Longtime hardcore/metalcore listener here, this is going on my workout/boxing rotation. Solid work man, good luck in all of your endeavors!

It very well could! That’s a little beyond my knowledge level, I did some googling because I like the topic but couldn’t tell you. I wouldn’t be surprised if there was some method to get rid of sediment after aging, it’s a very different grade but I’ve had aged cinnamon and rose petal mead and I bet coal filtration would have made that a much better experience.

Many, yes! It mostly depends on if it’s toxic. I have friends who homebrew/distill and we visited a distillery together recently and did the whole tour, it’s pretty interesting stuff. Some places are taking traditionally “clear” alcohols and also “finishing” them in re-purposed barrels. So for example, gin, by definition, has to contain juniper berries and must be at least 37.5% alcohol by EU regulations (which I used as an example since london gin is a staple) Traditionally, aged gin wasn’t really a thing but there’s a trend now of aging gin in re-purposed bourbon barrels. This gives the gin both color and flavor, while still following the legal requirement. Every country has different requirements on what process you must follow to sell an alcohol under that name, and some require certain alcohols to only be aged with certain types of wood. In short, it depends, but the creativity is getting wild.
