Essential oil distillation home made , rosemary - Huile essentielle distillation maison, romarin

In this video I show my very simple home made distillery for essential oils and distill rosemary oil. I use a pressure cooker, some copper pipe and a pot (for the condenser). Simple to put together and easy to run. (see bellow for more information)

Where to get the equipment:
Pressure cooker:
Try googling "pressure cooker" or "cocotte minute" (in French)  You want one that has a removable safety valve. I have an older version of this model,  Seb Autocuiseur Inox P0531600 Authentique 10L , new they can be expensive. You may know someone that has one and no longer uses it, that is how I found mine.

Condenser:
You will have to make this. I was given this by someone that no longer used it ! It was hand made. You need a 10 liter pot (or more) and some small diameter coiled copper tubing.

Connection from pressure cooker to condenser:
I used a flexible plumbing pipe, it is what I had and happened to fit perfectly without and special joining. Though this works it is not the best solution as the inside of the flexible wire mesh pipe is rubber/plastic. Best would be copper.

Making the oil:
- I used fresh cut rosemary (a fully packed pressure cooker - about 3 - 4 KG)
- a fifth of the pressure cooker is filled with water
- the condenser is filled with cold water, I also added blocks of ice and periodically removed the surface hot water and replaced it with cold water and more ice (if I had it) so that the condenser stays cool.
- after a few minutes of distillate production a fine layer of oil begins to form on top of the water
What come out of the condenser are two liquids: 1: hydrolat (also known as distillate water or floral water) the hydrolat is slightly perfumed, 2: essential oil.
-  I use a syringe to remove the water from the oil 
- the distillation process takes about 45 minutes
- the full 10 liter pressure cooker gave about 5ml of rosemary essential oil
