Harvesting Lavender for Distilling Lavender Reserve

We've grown our lavender from seed. Lots of genetic diversity. Each year we harvest and distill small amounts of "Lavender Reserve" essential oil and hydrosols. Lavender officianados love this essential oil. It is unique in aroma. There really is nothing else like it! Here's JD Higdon's Lavender Harvester. Each row only takes us about 3 minutes to harvest.

Western Juniper

Our most recent distillation was quite successful. Our wild crafters brought a ton of Western Juniper (Juniperus occidentalis) leaf for us to distill. We managed to obtain a final yield of 0.62%, that's not bad for Western Juniper. Previous distillations yielded less than 0.5%. Previous to distilling Western Juniper, we distilled Bay Laurel Leaf (Laurus nobilis). The oil is exquisite. The best Bay Laurel oil I've experienced (if I do say so myself!). The branches were brought to the distillery by someone here in Portland, who was pruning her fast growing tree. This is not something we will distill on a regular basis unfortunately. However, it is something I love to distill. The last time I distilled Bay Laurel was on the Island of Syros, in Greece. We did manage to produce 2 ounces of gorgeous essential oil and ten gallons of fragrant hydrosol.

Distilling Incense Cedar Leaf

I managed to locate an excellent source for wild crafted aromatic raw materials. This is very exciting to me, as it opens a door for access to some very interesting plants, some of which I've wanted to distill for a very long time. Included in that list is Wild Ginger (Asarum canadense), Arrow Leaf Balsam Root (Balsamorhiza sagittata), Pipsissewa - Prince's Pine (Chimaphila umbellata) and of course one of my favorites, Incense Cedar (Libocedrus decurrens-- aka Calocedrus decurrens) I started distilling a batch of Incense Cedar Leaf. The leaf had been gently dried and there was minimal stem material. This is very good, because the twigs are unproductive and take up room and cost energy. I distilled for three hours and obtained less than 0.5% yield. Then it dawned on me that I had made an error. As with all conifers, the scales of the "leaf" of the Incense Cedar are covered with a waxy coating. In order to break the coating down and get at the essential oils the coating protects, the "leaf" must first be soaked in room temperature water. I turned off my distiller, and left the steam soaked plant material to sit overnight. When I distilled the next morning, the essential oil flowed easily. I finally ended up with a 1.4% yield of essential oil and lots of interesting hydrosols. When I do my next run of Incense Cedar Leaf, I will add copper to the system to reduce the sulfurous "still note". The last time I distilled Incense Cedar was in a copper still and the oil was "sweet" right from the beginning. I will also soak each batch for at least 12 hours prior to distillation. Right now the oil and waters are breathing, like a fine wine. I hope in the future to be able to increase the percent yield to between 1.5 and 2.0 %. Cant' wait to distill Wild Ginger and Arrowleaf Balsamroot!

Distillery Opens in Sellwood

Finally!! We've opened our distillery in Sellwood. Sellwood is on the south side of Portland, Oregon. It's a great neighborhood, about 4 miles from downtown Portland. We have expanded our warehouse an additional 7200 square feet. Within this additional space is our new distillery. This is a small scale boutique distillery with capabilities for direct steam and water/steam distillation. In addition to serving as a functional distillery, this is also a show room for interested parties to view the various types of distillation apparatus we offer for sale. Our newest piece of equipment is a 35 gallon water/steam distiller, currently priced at $8780 US FOB Oregon. This is a self contained distiller that operates using propane as fuel for the burner. The water level is regulated with a float valve, so you never have to worry about running out of water. The condenser is also regulated for temperature so that you can set it to the temperature that you desire your distillate to be.

Distilling Lavandin Part 1

Distilling Lavandin Part 2

Greetings from Naxos

I spent the last month (June) distilling on the island of Syros in the Cyclades. I distilled rosemary, helichrysum, geranium and Bay Laurel. The Rose Geranium reacted with the copper of my Alembic distiller. The oil was initially clear but shortly turned into a "day-glow" green. This was easily remedied by adding citric acid to the oil, which precipitated the copper creating copper citrate. After decanting, the oil was the expected green color. I was pleased with the yield of oil from the Bay Laurel. The oil was on the low end of the expected yield (probably due to the wrong harvest time for the leaves), but it is extremely nice aromatically. The hydrosols are quite pleasant. I have sent the oils and waters off for analysis. Pictures will be added once I return to the USA in September. I'm currently on the island of Naxos Naxos is the largest island in the Cyclades. Unlike the other islands, there is plenty of water here. there are many lush (relatively speaking) green valleys here. Among the plants I've found here for potential distillation are: Vitex, rosemary, cypress, Jerusalem sage and lots of helichrysum. From here I'm headed to Chios to view the Mastic harvest and hopefully distillation of the essential oil. Then off to Crete for the Rock Rose (Cistus) resin harvest. I'll post photos as soon as possible. Kalo kalokairi!!

White Sage

I managed to distill about 445 pounds of Sacred Sage (Salvia apiana). The material was dry (perhaps two years old) with stems and leaves. Because of its age, I wasn't certain what the results would be. I've been pleasantly surprised. Because the material was dry, distillation went very quickly. Each batch of near 100 pounds only took about 1/2 hour. I distilled this oil using my 100 gallon stainless steel distiller. I obtained a 3.5% yield of a pale yellowish oil. Currently, the oil is being allowed to breathe, to eliminate the still note. The aroma is very pleasant, characteristic of White Sage. I believe it will sweeten up nicely. It will be interesting to see the analysis of this oil. I'm curious to see the difference between this oil, distilled from dry (old too) leaf and stem, and oil distilled from freshly harvested material. The Lavandin oil I distilled in July is ready to be bottled. This Lavandin was grown in Scholls, Oregon at Mountainside Lavender.

Distilling Season

It's been a busy distilling season. While at Mountainside Lavender I managed to distill 10 batches of Lavandin. The yield from each batch was approximately 2.5 pounds of oil, and lots of hydrosols. Hood River Lavender had a fun Lavender festival. There was wine, music and lots of boots selling hand made products. The weather was perfect. I had a table offering our hand hammered copper Alembic distillers. I also managed to distill some of our "Population Lavender" this is lavender (Lavendula angustifolia) which was grown from seed. Because the lavender was grown from seed, there is quite a bit of genetic diversity in the plants. Most lavender farms grow their lavender from clones, which offers no genetic diversity. The resulting oil from our genetically diverse crop is exquisite. We sell this beautiful essential oil here. Later this week I will be distilling Sacred White Sage

Businessman enjoys sweet smell of success

Aromatherapy - The quality of the essential oils Robert Seidel sells earns him a following

Thursday, April 26, 2007

POLLY CAMPBELL The Oregonian

In 1977 Robert Seidel started a business that made a lot of scents but not much money.

In fact Seidel, 56, says the first few years he made no money at all.

But 30 years later, The Essential Oil Co., a wholesaler of essential plant oils based in the Sellwood neighborhood of Southeast Portland, is doing quite well.

Last month he shared trade secrets with students at Clackamas County's Tree School, an annual program targeted to those in forestry and timber management fields sponsored by the Oregon State University Extension Service, Clackamas Community College and local forestry groups.

"Oils are a value-added product," Seidel said. "When you harvest a tree you can collect the branches that you cut off and distill the oil."

The essential oils Seidel sells are used by large manufacturing companies and individuals throughout the world in soaps, cosmetics, candles, lotions and other consumer products.

Seidel's considered a pioneer and a respected expert and distiller in the aromatherapy industry, according to those who buy from him.

He loves talking about the distillation process he began learning as a college student in New York more than 30 years ago.

In those days Seidel was studying forestry resource management. He became enamored of the smell of balsam fir and began researching methods for capturing the fragrant oils.

He discovered that few people knew how to extract the oils, and many companies that claimed to be using essential oils in their products were fabricating the scents in laboratories.

Using information he found in a couple of old books and a lot of trial and error, Seidel began distilling essential oils from Douglas fir and later from the needles, branches, leaves, stems and petals of other plants.

He used a distiller made from a refrigerator coil and a pressure cooker to produce a small quantity of peppermint and a few other oils. He also began buying and selling small amounts of essential oils.

"There were very few people then who knew what an essential oil was," said Seidel, who worked full time as a plywood inspector for a trade association in the late '70s. "So there was me and about five hippies that I sold to."

n 1981, when the timber industry foundered and Seidel lost his job, he turned his passion for essential oils into a full-time profession. He also drove a cab for a while and took other jobs to pay the bills while building his business.

Initially, the company sold oils through a catalog. Now customers from around the world buy pounds of his products from the Internet. He also sells to a loyal group of regional customers, many of whom come to the sample bar at his Sellwood office and warehouse to get a whiff of the different aromas.

Once they meet Seidel, customers are likely to come back, said Joe Orcutt, a lavender grower from Hood River who has purchased oils and a distiller from Seidel's company.

Seidel exudes passion for plants and their essence. His products, though sometimes more expensive than others, are of the highest quality, Orcutt said.

The quality is in part because Seidel "goes out in the field with the growers," said Heather Michet, an aromatherapist from Sandy who buys about 90 percent of her scents from Seidel's company.

Travel is part of the allure of the job for Seidel. He spends weeks every year on the road.

"I travel to distillers and visit with them to make sure they are doing what they say they are doing. I want to see the plants growing," Seidel said. "I like to travel and meet people, and it's a great way to see the country not just as a tourist."

In a couple of weeks Seidel will be in Fiji meeting with sandalwood growers. He's visited Egypt and India in search of jasmine and met with rosemary growers in Tunisia and Israel.

When he's not creating his own line of essential oils, Seidel is helping others distill theirs through a steaming process that vaporizes the oil before cooling it back to a watery liquid that leaves the oil on top. He also builds and sells distillers.

When time allows, Seidel attends area festivals and events to demonstrate the distillation process and teach others how to do it.

"I like it every time I distill," he said. "You put in the raw material and you get this beautiful smelly oil out. It's like capturing the essence of the plant."

From The Capital Press:

Essential oils can be distilled from foliage

Process works well for lavender growers, company president says at Tree School

Mateusz Perkowski Capital Press Staff Writer

Out of the countless things that can be made from conifers, toiletries are seldom at the top of the list.

While trunks are commonly used for lumber, it's possible to extract value-added products from foliage as well, said Robert Seidel, president of the Essential Oil Co. in Portland.

Conifer needles contain essential oils that can be distilled and sold in liquid form or used in lotions, soaps, perfumes, aromatherapy candles, balms and similar goods.

Although it's unfeasible for family forest owners or Christmas tree growers to generate enough essential oil to compete on a wholesale level, they can find a retail niche for smaller amounts, Seidel explained.

"If you're selling it directly to the consumer, then you can make some money at it," he said. Seidel gave a distilling demonstration at 2007 Clackamas Tree School in Oregon City on March 24.

The process has been working well for lavender growers in Oregon and Washington, who add essential oil and flowers to various personal care products, he said.

Each year, Seidel travels to lavender farms with his mobile still; he is paid for his efforts with a portion of the oil he extracts. Such an arrangement also may be practical with other materials besides lavender, but only if it doesn't require traveling long distances, he said.

Growing lavender for essential oil is much more common, but in terms of cultivation, tree farmers have a distinct advantage: unlike lavender flowers, conifer foliage is simply a byproduct and doesn't require special maintenance or irrigation, Seidel said.

Christmas tree growers can gather material left over from pruning, while woodland owners can save branches they've cut from logs, he said. "One tree is going to have a lot of material," he said.

At the wholesale level, one pound of essential oil sells for $10 to $25, he said. Distilling 100 pounds of raw conifer material yields about half a pound of oil and requires industrial-sized equipment that costs at least $25,000.

Obviously, a full-blown commercial venture would not be economical for tree farmers, Seidel said. Even if someone invested in a commercial plant, producers in Central and Eastern Europe would be able to undercut them on price, he said.

Small stills, on the other hand, only process about 10 to 12 pounds of raw material at a time, producing an ounce of oil or less after three hours of boiling. Such stills cost $1,500 to $3,000, but they also can be built from inexpensive metal objects.

Seidel fashioned his first still from a pressure cooker and a copper coil. Also, they can be heated with a propane burner or wood, rather than a costly boiler.

"There are some interesting configurations," he said. "A guy can get creative."

Although the amount of oil these stills produce is minute, a little bit goes a long way when it's diluted in personal care products - for example, a pound of pre-made, unscented soap requires only one-sixteenth of an ounce of oil, Seidel said.

To expedite production, it may be wise to team up with someone - a wife or daughter, for instance - so that one person is in charge of distilling and the other handles blending and packaging, he said.

The organic and natural personal care industry generates about $5 billion a year in sales and is expected to grow to $11 billion by 2009, according to the Natural Marketing Institute.

In such an expanding and competitive market, distilling one's own essential oil can be a big selling point, particularly if consumers can see how the product is derived from raw needles in a still, said Seidel. "People like to see how things are done," he said.

This marketing angle has allowed Seidel to sell essential oil his company has distilled for up to $15 a half-ounce, he said. "With retail, the sky's the limit."

Distilling essential oil from tree needles isn't going to make anyone rich or generate enough money to retire on, but Seidel believes it's a viable way to garner some value from a waste material - and have some fun at the same time.

"Every time I see oil come from the distiller, I'm amazed," said Seidel. "It goes back to the old alchemy days."

Distilling Frankincense Gum

I managed to obtain some fresh prime Olibanum (Frankincense) Gum (Boswellia carterii) from Somalia. I have distilled Gum Olibanum before, in my 100 gallon stainless steel steam distiller. It was a successful distillation, but an incredible mess. Frankincense Gum is actually a gum/resin. Partially water soluble. Inside the steam distiller, the gum would melt from the heat and water. Globs of gum covered the steam spreader bars. I normally distill plants such as lavender at about 1 pound of pressure. For this gum, I had to boost the pressure to 5 lbs, to keep the spreader bars clear. In the steam distiller, the gum bubbles up and expands. If too much gum is placed in the still, the gum will bubble up and possible clog the condenser.

For this distillation, I used a 40 liter rotating column Alembic distiller. I left the column down and performed a hydrodistillation. The most efficient quantity of gum to distill in this size distiller is about 5 pounds. I added enough water to insure that I would not run out of water during distillation. It is impossible to add water while distilling to this traditional style Alembic distiller. For each batch, I distilled for 4 hours. The first batch had 5 pounds of gum, the second batch, 8 pounds. The expected yield was 5%. My actual yield, was 4%. I am very pleased with the result of this distillation. The resulting oil is sweet and pleasantly aromatic. I plan to distill this oil on a regular basis. Another interesting distillation I did recently was Osha Root Powder (Ligusticum porteri). This was a test batch for a company that manufactures medicinal products which include Osha root and its extractives. It was a hydrodistillation because the raw material was freshly powdered root. For this distillation, I used a 7.5 gallon Stainless Steel Table Top distiller. I obtained a yield of 3.75% Next week, I will be distilling some incredible Sandalwood Powder (Santalum album). This is a very pure and aromatic heartwood powder directly from Mysore.

Distilling at the US Botanic Gardens, Wash DC

At the end of July, I was invited to the US Botanic Gardens in Washington D.C. to demonstrate distillation for the general public. The Botanic Gardens are very beautiful, containing specimens of plants from all over the world. At the time I was there, the Ylang Ylang Tree (Cananga odorata) in the gardens was flowering. What a fabulous aroma. A flowering branch was placed in a vase for all to enjoy.

We had Lavandin flown in from Hood River Lavender. Despite the long distiance that the flowers traveled, and the loss of a bit of color, the buds were still laden with oil. The distiller I used was one that I designed myself. A Stainless Steel table top distiller. It was designed to use either gas or electicity (external hotplate). We used a small 10,000 btu butane burner, which worked like a charm. I used about one small can of butane per batch. many people from all over the world stopped by to see what I was doing and ask questions. The most frequently was "Where is the restroom?" followed by "Are you making coffee?" Most people had never witnessed the distillation of essential oils. There was a great deal of fascination in the process. Once I filled the still and started cooking, the whole room was filled with the aroma of "lavender". This drew people to discover the source of the aroma. I packed the distiller as full as I could with lavandin flowers along with the stems. The distiller has a total capacity of one cubic foot. This equates to 28.4 liters or 7.5 US gallons. During past distillations in a similar distiller I was able to obtain 5.5 ounces of oil per batch, with distillation times up to 4 hours. For demonstration purposes I reduced the distillation time. I was still happy with the yield despite the reduce distillation time (about 1.5 hours) When distilling 65% of the oil you will obtain s distilled during the first 25% of your distillation time. The oil flow diminishes with time as the plants are exhausted. Once the distiller was packed with flowers, I added water about 1/3 the way up the inside of the retort (the distilling pot). This distiller is equipped with a sight glass so that I can monitor the water level inside the distiller. Lavandin is hydrophilic and will absorb sorm of the water in the distiller. The lid is then put in place, and the stainless hose coming from the lid (bird's beak) is then attached to the condenser. Between batch changes the distiller is very hot. It's adviseable to wear gloves druing this operation. Better safe than sorry. Once everything is attached, the lid is tight and the condenser filled with water, I'm ready to start cooking. It took about 1/2 hour for the water to come to a boil. The first oils started flowing about fifteen minutes later. The butane gas burner was a pleasure to use. It enabled me to reduce the temperature once the distiller came to a boil, which in turn helps to reduce fuel consumption. Once the distillate started to flow from the condenser it was captured in my Florentine separator, my Essencier. This is a valuable tool for the small scale distiller. It permits automatic separation of the distillate waters (hydrosols) from the essential oils. Although the process is simple, once it's understood, many people were mystified as to what was happening. I explained the process from beginning to end about two hundred times during the day. I didn't mind it of course because I was having fun, doing what I enjoy as well as for the pleasure and edification of others. When the essential oils started flowing from the Essencier the process was met with amazement. Another mystery is the workings of the Essencier. I've been distilling for a long time, and I'm still thrilled when the oils begin to flow. It really is Alchemy. All of the above photos are credited to Mr Steven Buhneing.

Distilling in Greece 2006

During May of this year, we distilled once again on the sunny island of Syros. Syros is a beautiful little island situated in the heart of the Cyclades. We distilled; thyme (harvested wild), sage (Salvia triloba - harvested wild), Rosemary and Rose Geranium. Our yields from thyme, sage and rosemary were quite good, slightly above the expected yield as outlined in the literature. The Rose Geranium was a disappointment. We have the Rose Geranium planted on a local farm. The low yield is most likely due to improper cultivation of the plant. This is only the end of our first year with the geranium in the ground, we're learning. Next year we hope to increase the yield considerably. You can register for next year's Summer School with the American College of Healthcare Sciences. This year's session was lots of fun. We ended with a graduation sail to the archaeological island of Delos. Our 65 foot wooden Turkish barque was escorted part of the way by some local dolphins. Very magical!

Busy Distilling Season

This has been a busy season for distillation. Beginning with our Summer School on the island of Syros during the month of May. We distilled: Thyme, Rosemary, Sage and Rose geranium. Summer School 2006 Since then, I've been our distilling Lavender and Lavandin. I started at JD's Art Farm, where we have "population" lavender growing. This lavender (Lavendula angustifolia) was grown from seed. The resulting plants offered quite a bit of genetic diversity. Our end product is exquisite. The oil is a "perfume" all by itself. From there I went to Hood River Lavender for their "Lavender and Butterflies" festival. I distilled angustifolia in a 100 liter copper Alembic distiller (the same style I use in Greece). For the last week, I've been distilling Lavandin (grosso) at Mountainside Lavender in Sholls, Oregon. It's been a good year with plenty of heat and great yields. Please visit this page again. I will be posting some photos soon.

Distilling Rose Oil

How to Make Rose Oil Several years ago, I joined Dr Peter Wilde (pictured on the left) on a fabulous trip through Turkey. I like to visit distillers of essential oils that I purchase to sell through The Essential Oil Company. I like to see how the plants are grown, harvested, handled and distilled to gain confidence in my suppliers and develop a personal relationship with them. This ensures that my customers receive only the best essential oils possible. If you have never been to Istanbul, you are really missing something. This is truly where East meets West. History and mythology. The senses are assaulted from all directions. Sights, sounds and aromas. We travelled in a group from Istabul to the Mediterranean sea. The region around Isparta is the heart of rose production in Turkey The roses are generally harvested during the month of June. The harvest begins at daylight and proceeds until about 10 AM. It's always best to harvest the rose petals while the dew is still on them, and before the heat of the day causes the essential oils to evaporate into the atmosphere. Women do the harvesting. (Men make the tea for the morning break- nice job) Only the rose petals are taken, no green bits allowed. I tried my hand at harvesting but found that I was wasn't built for it. I spent most of my time trying to get the thorns out of my hands, and "unhooking" my shirt from the ever present thorns. Once the rose petals are harvested, they are placed into sacks and loaded onto trailers. Care must be taken not to bruise the rose petals. The rose petals then make the short journey from the rose fields to the distillery. Once at the distillery, the sacks of rose petals are unloaded from the trailer and dumped on the smoothe cool concrete floor . The rose petals are allowed to ferment a bit. Decomposition apparently helps to produce more rose essential oil inside of the petals. The rose petals are left for seveal hours to allow nature to do its work. The room is incredibly aromatic. Ms Dorene Petersen, President of the American College of Healthcare Sciences found the specter of a pile of rose petals irresistible. Overwhelmed by the aroma, Dorene temporarily passed out, reportedly falling into a deep rose inspired sleep . We managed to bring Dorene back to her senses, otherwise she would have been loaded, along with the rose petals into the large distillers. Rose petals are distilled via hydrodistillation. Rose petals are delicate. It is necessary to have the rose petals float freely in water in order for them to be distilled. Steam distillation does not work for rose petals. Once hit with the heat of the steam, the rose petals form mush which does not permit complete distillation. Picture a pot of oatmeal cooking. Looking into the pot, you will see "steam vents". This is exactly what happens to rose petals if steam distillation is attempted. The steam will find its way through these "tunnels" and will not adequately contact with the rose. In addition, the heat and pressure will destroy some of the finer "notes" in the essential oil. So, after allowing the rose petals to ferment a little bit, and with the removal of Ms Petersen, the rose petals are loaded into th distillers. Inside the distillers is about 1500 liters of water. Each distiller is then filled with about 500 kgs of rose petals, and packed to the top, to overflowing. Steam is introduced into the bottom of the steam jacket which surrounds the copper container that is holding the rose petals and water. The steam causes the water inside the pot to boil. This is similar to a "Bain Marie" double boiler. This works quite well. If the rose petals and water were in a pot, without the "double boiler", and heated via direct fire, you run the risk of burning your rose petals. This is due to the fact that the water inside will evaporate as distillation proceeds, and the remaining rose petals will contact the hot sides of the distiller. One thing you never want to do is burn your raw material. The distillery is a two story operation. Rose petals are loaded into the top of the distillers (retorts). When the distillation period is over, the bottom of the retort is opened to remove the spent rose petals and remaining waters. As distillation proceeds, the distillate is captured in a receiving can (Essencier), with the Rose oil (attar, Otto) floating to the top. It's very important to capture the waters which exit the Essencier and redistill the waters to remove the essential oils which haven't adequately separated from the waters. The product of the redistilled waters and and the essential oils which float to the top of the Essencier are then filtered and blended back together. The resulting products are beautiful Turkish Rose Essential Oil and Rose Flower Water (these are the hydrosols that flow from the Essenciers) Turkish Rose Attar (Rose Oil, Rose Otto) is similar to that distilled in Bulgaria. The rose used is the beautiful Damask Rose. Rose Oil is among the favorites used in herbal medicine and aromatherapy.

Percent Yield

There are many variables which will determine the percent yield you will get from your raw material. Growing conditions, harvest time (including time of day), condition of the material (dry or fresh), distillation time etc. Here's a useful guide which can tell you what you may expect to obtain from your distillations. Feel free to add your data as this page can easily be updated.

The Copper Essencier

The Copper Essencier was designed for separating essential oils and hydrosols from distillates when using smaller apparatus. I have used it successfully with our table top distillers, our copper Alembics and even with our 100 gallon portable stainless steel distiller. It also works great as a secondary receiving can. At times, I've noticed essential oils in my waters which haven't separated adequately. Perhaps because the condenser is too cold, or the flow of distillate is too great. I place the Copper Essencier so that it captures the waters coming from the primary separator. This affords more time for the separation. I have also saved my initial waters and added them back into the distiller for redistillation, but I find that secondary separation is quite efficient.

Distillation on a Greek Island

Soon, I'll be on the island of Syros in the heart of the Cyclades. Syros is a beautiful and peaceful island with a rich history and culture. The Australasian College of Health Sciences is sponsoring this hands on Summer Session For ten days, we will enjoy the relaxing healthy lifestyle of a Greek island amidst a wide variety of Mediterranean plants and herbs. Instruction is by ACHS’s outstanding faculty, with bonus guest lectures from leading professionals in the industry. Greece is the birthplace of the “father of medicine” Hippocrates, who believed the body should be treated as a whole and that food should be our medicine. Summer session 2006 is an opportunity to immerse yourself in this ancient land. Syros is close to Mykonos and Santorini and not too far from the island of Cos where Hippocrates founded a medical school and began teaching his ideas. Syros is an enchanting location for this residential session. We have Rosemary and Rose Geranium planted on the island, which have been grown using organic methods. In addition to these plants, we also hope to harvest Sage, Thyme and Helichrysum from the wild. The hills on Syros are quite aromatic. It's a very heady experience to walk on a hillside covered with wild growing aromatic plants with the bright blue sea lapping the beaches below. It's Aromatherapy, pure and simple. We will be distilling in a 100 liter rotating column copper Alembic. The Alembic stands about 6 feet tall when the column is up, in the position for steam and water distillation. Traditionally, this apparatus is used for making Eau de Vie, Tziporo, Grappa etc. The Essential Oil Company represents a group of Artisans in Portugal who make many and varied distillers, all in the traditional fashion. With very little adaptation, I find that this equipment is fabulous for making essential oils and hydrosols. There are no gaskets for these distillers. Joints between the Alembic head (onion) and the column, and the joint between the column and the "pot" are sealed using dough made from rye flour. This is a very old and established method, and it works like a charm. Only rye flour will work. Rye seems to absorb moisture and stay somewhat soft, while other flours will dry and crack from the heat of distillation. Some folks make a paste with rye flour and water and smear it over the joints. I prefer to make a dough, roll the dough into a rope and press it into the joints. Our Alembic is fired with propane. We will also distill in a propane stainless steel table top distiller. The Alembic can hold about 50 pounds of raw material. The table top can hold up to 15 pounds. We will be distilling the same material in both distillers so that we can see the difference in the products. For separating the essential oils and hydrosols we will use our copper Essencier and stainless steel Florentine Separator. Last year was quite an experience getting our equipment into Greece. We couldn't get the stainless steel distiller and Florentine Separator out of customs. For our first few batches from our copper Alembic we had to catch the distillate in a bowl and then decant the oils using pouring and pipettes. What a pain in the neck. There was some loss of essential oils. It was also an expensive excercise with customs fees seeming somewhat arbitrary. We distilled Thyme, Sage (officinalis), Pine (Aleppo), Rosemary and Rose Geranium. Thyme is a protected plant on the island, because Thyme honey is a specialty product. In order to harvest, we had to get permission and be well away from beehives and beekeepers. Participants in last year's summer session had a great time. They made a variety of natural products from the plants they harvested. Not just essential oils. I can't wait to get back to Syros. It's a lovely environment to work and play.
