My preferences definitely change too, though it might be more to do with the situation than the weather.

I will always drink red wine, usually pinot noir and tempranillo.

In the summer, I tend to drink clear liquors in cocktails (mainly gin and tonic). If it's hot and I'm outside, I like beer and white wine. In the winter, I become more of a whisk(e)y drinker, generally scotch neat, an old fashioned, or a Manhattan. Sazeracs are always good too.

I like beer, but usually only drink it in conjunction with certain foods (Mexican, sushi, Thai), or if it's hot out.
