What's your favorite adult drink? I'd personally prefer your favorite drink being on the basis of flavor rather than "this gets me drunk the quickest." My favorites are port wine, gin & tonic, and hard cider. Gin & tonic is very sweet, and I love the bitterness. Port wine is great just because red wine itself, in my own opinion, always seems to be an incomplete flavor that brandy completes in port wine. Hard cider is just very sweet, and I love apples.
