THC isn't water soluble, but it is alcohol soluble. This has me curious as to whether or not it might be possible to use something similar to the "double fermentation" techniques that are used in brewing some beers to finally achieve fermented cannabis.
Imagine if someone in a country where cannabis is legal were to add cannabis to a 5-20% solution of alcohol to extract the THC. After allowing the finely ground herb to macerate for a few days, they then add fruit juice or a combination of molasses and water to reduce the alcohol content to a lower level (like 2.5-5%). With a lower alcohol content and a new source of sugar, they restart fermentation with a yeast strain possessing a high tolerance for ethanol.
Saccharomyces cerevesiae is the common brewer's yeast, but other yeasts and bacteria could be used in conjuction as well: Torulaspora, Brettanomyces, Zygosaccharomyces, Pediococcus, and Lactobacillus are all used in various fermented products. Acetobacter can also convert alcoholic solutions into vinegars. The idea is that one or more of these microbes might generate new metabolic byproducts of THC and some of these might be of improved potency, different duration, or else exhibit some other pharmacological differences from THC.
For that person in a country where such activities are legal, is this an idea worth trying? Have I failed to consider something?
