I am 21 years old, can someone teach me about alcohol?

Yes, I know, broad question, but let me this easier and tell you that all I currently know. Firstly, it seems that if I were to divide alcohol into subcategories, you got beer, wine, and spirits, the ladder being the most robust. Beer is made of wheat, wine grapes, and spirts… well, I guess it varies, but I am not entirely sure. It seems that spirts are the strongest one on average… so if I want to get that extra buzz, go for that one. Personally, it’s my favorite so far because it just screams gentlemanly class like, “yeah, I can drink that”, but I also enjoyed the taste of an old fashioned I had recently. Beer tastes pretty good too but I want to maintain my hot bod, so I try to refrain from the possible reality of a beer belly. Um… yeah. I had a white wine at a restaurant and didn’t like it; I think it was to bitter. But I tried a white wine for thanksgiving and actually enjoyed it. Maybe a more refined pallet after coming to like whiskey? Idk. Like, what alcohol is good and for what occasions? As a spirits guys, what would you recommend?
