We operate a small commercial-scale essential oil distillation unit that is made from 90% recycled stainless steel.

Building the still was time-consuming and challenging but we are totally pleased with the final product! It can hold up to 120 lbs of plant material and automatically maintains constant low-pressure, low-temperature steam for up to 9 hours without refilling (20+ hours with hydrosol recirculation). It was built with 100% stainless steel using recycled materials wherever possible.

For instance, the stainless barrels held cinnamon essential oil for a ubiquitous Atlanta, Ga based soft drink maker; the stainless screening for the plant material baskets came from unused but discarded washing machine drums (a pallet or two must have been bent in transit); the stainless waterproof electronics box, all of the stainless tubing and many stainless fittings were fortunate scrap yard finds. The (new) dome for the top of the still was a traditional giant stainless Mexican cooking dish known as a Cazo. Of course, stainless steel was used for all welds. Our still is electrically heated to allow for greater flexibility in distillation location.

We use pure mountain spring water from our remote forest farm in our distillations and cold, plentiful creek water to cool our still.

Another key to the distillation puzzle is the receiver/separator; it collects the cooled steam (hydrosol) and oil from the still and gives it space to separate. The oil floats on top of the hydrosol; the latter of which drains from an outlet at the bottom of the separator. We tried building our own separator from stainless tubing… but quickly learned it needs to be adjustable and we need to see what’s happening inside. So we found a great local glass blower to custom build a laboratory-quality one based on some general principles and drawings. It works absolutely flawlessly! Plus, look at it… Beautiful.

  1. What a magnificent work. Thousand thumbs up and more grease to your elbow. I just love it. Am also planning to go into essential oil distillation and I have been looking here and for information about the process and equipments involved and that brought me to your site. I would be happy if we will stay in touch to share ideas for my project and to learn more from you. Kofi from Ghana where a lot of natural stuffs are available to distill. Thanks and hope to hear from you.

  2. I agree with Kofi, this appears to be quality home craftsmanship.

    I too stumbled upon your website during the course of some preliminary online research. We have a small farm, and are exploring essential oil steam distillation as a high value-add post-harvest process. I wonder if you would be willing or able to quote a price for fabricating one of these for our use?

    Thanks very much,


    1. Hi George and thanks for your message! Yes, we are open to that idea and have done so a few times in the past. We’ll send you an email to discuss further. – Ian

  3. I have a large Monterrey Cypress Tree that I would love to have essential oil made from. Would you be able to do something like that for me?
