We're coming in somewhere around $50 a month, I think. That's a 6-pack, 2 bottles of wine, and some liquor...
Liquor: We both love Scotch (Speyside and Lowland for me, Islay and Highland for him), and our latest favorite is the Balvenie Doublewood. He loves tequila. Our current bottle is Riazul, an anejo. Quite honestly, the Riazul drinks like a Scotch to me!
Beer: local craft brew at about $8/6pk but go through them pretty slowly.
Wine: generally in the $10-$15 range, lots of merlots, cab sauvignons, malbecs, and the occasional rose, pinot noir, riesling, or sauvignon blanc.
We don't go out for drinks very often, but each time we do, we spend $15-30.
