The higher ABV, the higher the chance I'll like it.
These days I've been drinking more liquor than anything, just to keep the beer belly from getting any larger. I stick with either Hendricks Gin or Red Breast 12 or 15 year. The fiance is pretty damn irish and drinks Jameson like it's water, so I use that as a go-to when my mainstays aren't around.
Beer wise - Dragon's Milk, Bourbon County Stout, Dogfish Head 90 Minute, Delerium Noel, and Chimay Blue are fantastic.
If my friends and I are playing drinking games though? Cheap beer FTW. Ain't no way I'm wasting the good and pricey stuff on a game of Hockey.
