I like a good hefeweizen or dunkelweizen, although the high carbonation doesn't exactly get comfortable with a belly full of food.
My favorite, though, is for somewhat sentimental reasons, even though it was Christmas. We went over to my Aunt and Uncle's house. They are big wine drinkers with an extensive and excellent cellar, but they know almost diddly squat about beer. They know I like beer, though, and they wanted to indulge me. When we arrived, my Uncle said "I went to [the store] and asked them what I should get."
I thought I was certain to find some sort of Shiner Bock or ca-ca beer. Instead, when he led me over to the bar sink, it was full of ice and Samuel Smith Imperial Stout. Oh, yeah. When I showed my wife, she shared my sentiment. Since then, it's been my favorite holiday beer.
