Hello Daisy
I wondered about making homemade,
quality, essential oils too and a couple of years ago I started asking questions and I went searching for info....
Here's what I can add:
if its for homeuse or maybe domestic market/stall sales only, you may be able to use a
smallish still (ie bigger than a homebrew shop model; you'll get very little from them; but less than a distillery size) to obtain a 'reasonable quantity' of finished product.
You will also need to deal with significantly different quantities of base botanicals for different oil extraction...and the only 'true' way is to use a basket somewhere on the top of the liquid in the boiler i.e. in the vapour path.
There are often issues regarding the purity and effective shelflife of finished oils too. If you are considering sales, you will need to be meticulous about base botanical source and also the distilling process undertaken (time/temp etc). There will also be potential problems with 'output' contamination if the distillations are varied.
if its for anything other than a homebased output (ie homeuse levels), you will be confronted with significant setup costs and possibly 'red tape' (ie government interference).
All this is not too say its impossible or even inadviseable, just not easy. Good luck and I would love to know how you go.
