It’s almost certainly cheaper to just buy it if you’re operating on the smaller end of the scale. For some of the bigger processors though, that 2-5% solvent loss adds up in a real hurry, especially if you’re using beverage grade/excise paid ethanol.
I was just talking about doing this the other day! Seems like if you could get a few hemp processors to go in on it it would be super worth it and would make a waste stream useful. Shall we start a future4200 hempthanol production plant?
I think it’s not a bad idea, though probably a lot easier down in the US than it is up here in Canada. I think it’s a lot easier to get the required exemptions if you’re doing your own distillation for industrial purposes rather than for sale up here.
On the smaller end of the scale, I bet there’s a market for a Hemp/Cannabis distillery. Literally just vodka/whisky/etc made from waste biomass. No cannabinoids, just trendy (and likely super expensive) booze.
Ehhh, at least you guys have it legal on a federal level now. I can just imagine applying for a federal permit here with the ATF and ending up creating a legal mess for yourself when their DEA buddies catch wind of what the industrial use for non-denatured etoh is. If we can even get away with not having to denature it for industrial use.
I read somewhere that the permit for comercial beverage ethanol distillation is around 200k though. If you could market that liquor and make your own solvent, the permitting costs would probably pay for themselves pretty quickly.
I’m a craft distiller in B.C. I’ve been thinking about this project for quite some time.
I’ve done some minimal steam treatment to try and break down some of the cellulose. If you’re thinking about making it into ethanol for drinking I can assure you it will taste like garbage lol. Steamed weed doesn’t really have the best flavour profile. It’s suuuuper vegetal. You’re gonna have to really charcoal the crap out of it or make a super earthy gin, it’s pretty limited as a spirit base in my opinion.
I wonder if you could throw the biomass in a gin box and run rye vodka through it to pick up the terpene notes? Craft distilling used to be a pretty big hobby of mine, so this has definitely peaked my interest.
I’ve run the same organicalcohol.com (used to be alchemical solutions) over the same strain of buds at -80C 4x, recovered in the rotovap => EHO, then fresh buds, and that “terpshine” was an absolutely gorgeous representation of the starting material. Do wish I’d started with the organic grape 190 rather than the corn based 200proof.
