For someone who do doesn't drink

Would you think it'd still be a good idea to stock up on alcoholic drinks? I've read a lot of scenarios where alcohol might come in handy for bartering purposes, as a painkiller substitute, and I've even heard some people claim it's a decent substitute for rubbing alcohol.

How likely would a scenario where we go back to bartering for goods, specifically alcohol, rather than using some form of standardized currency be?

If you guys think it's worthwhile investing in alcoholic beverages, what should I invest in? I've got little knowledge of alcohol to begin with, other than generic terms for types of alcohol, like vodka, whiskey, ect. and a few of the big brand name beer and wine manufacturers. What would even be the best way to store them, just let them sit in my basement for 20 years?
