I've always been fascinated by these trace alcohols. They are very rarely talked about. Some people will say 'alcohol is alcohol' but that's actually incorrect.

I've always been fascinated by these trace alcohols. They are very rarely talked about. Some people will say 'alcohol is alcohol' but that's actually incorrect. Alcoholic drinks are bioactive concoctions made of organic materials with multiple active ingredients-- the hops in beer for example has a slight effect on cannabinoid receptors which is why beer tend to makes one sleepy. Like you said there are a lot of trace alcohols as well. People report having different effects from different alcohols-- vodka can be numbing while wine feels more relaxed, etc. By categorizing an inventory of these trace alcohols and their effects, one could hypothetically create customized alcohols with varying effects and levels of metabolic load. These trace alcohols are also called fusel alcohols. A lot of these are very weird chemicals with varying effects, though, not all positive. Propan-1-ol is a fusel alcohol that is thought to be 2-4 times stronger that alcohol and similar in effects, but can lead to high anion gap metabolic acidosis as a lethal side effect. So there are likely safe maximum levels of each fusel alcohol that can actually be added. Fusel alcohols are something brewers take great care to avoid, after all, as they can cause many negative effects. There's something interesting there and I'm surprised no one has pursued this before(AFAIK)
