I prefer stronger alcohol in very small doses (20-30g or so), just for the taste and for unwinding after a hard day. I don't like feeling 'buzzed', let alone drunk, so I don't usually drink more than that: a normal-sized bottle of good scotch can last for several months.

Taste-wise, I like higher-end scotch whisky (mostly various single malts, peated or otherwise, including cask strength ones) and plain simple bourbon, but I can't stomach any dose of vodka - I find its taste disgusting. I also enjoy good wine, no matter white or red. I don't drink beer, though I can definitely enjoy it.
