I used to drink Hamms, Schlitz, PBR and many others, but I didn't learn what a good beer was until I went to Germany. Loved those flip top bottles and that strong beer! Today, I drink Sam Adams on the few occasions that I actually drink beer, you know like celebrating National Orange Week or some other national holiday.
I was an American army brat going to high school in Munich, Germany when I learned to drink beer, real bier. When I came back to the US I spit the first drink of American beer out, I thought there was something wrong with it. It tasted awful.
