This is my kinda topic
Beer: For a long time now my two favourites are from breweries in Toronto: Great Lakes Brewery's Pompous Ass English Ale; and Mill Street Brewery's Tankhouse Ale. I love all kinds of beer but I will turn my nose up at boring, tasteless big-name stuff (Canadian, Blue, Bud, Coors Light, various generic Euro lagers, etc). Life's too short to drink bad beer.
Wine: I mainly like reds but what I drink depends a bit on the time of year. In the summer I like something a bit lighter, top choice is usually La Vieille Ferme or a pinot noir. The rest of the year I probably take something heavier, a malbec or cab. sauv.
Mixed drink: Not something I do very much, but every now and then I like rye + ginger ale or dark rum + coke with lime. Need at least a 50/50 mix or else I'm just drinking pop and what's the point of that.
Straight up booze: Scotch for sure. I'm not a connoisseur by any means and can happily drink anything that isn't obviously cheap shit.
