Scotch - Yes, but if I'm drinking scotch, my preference is an Islay scotch with lots of peat and smoke.
Bourbon - Yes. Some nice local offerings, but I also enjoy Gentleman Jack. I don't care for Knob Creek.
Beer - Yes. I like most different beers, but like Bill, I am good for 1... maybe 1 1/2. I like stouts and porters, but I do not care for imperial stouts (too strong and astringent for me), and I'm very, very tired of the IPA "hoppier the better" fad. I do like a nice German lager. Also, a nice bock or doppelbock is an excellent beer to have with a good steak.
Wine - Yes, though I don't know a lot. I like a nice Cabernet with a meal, but that's about it. I tend to buy wines in the $10 per bottle range, and feel like anything more expensive than that is lost on me.
Gin - My wife likes gin, so we usually have some on hand. Her favorite is Hendricks, but we have a local distillery that makes great gin and also...
Aquavit - probably my favorite spirit.
Vodka - Not generally, though if I drink it I usually have Gray Goose, Tino's or a local vodka from Soft Tail made from apples.
Tequila - no.
Oh, regarding karate, no comment.
