I used to drink the standard Bud Light beers, but I lived in Germany for a while and grew to love pilsners. After that, my first craft beer was Sierra Nevada Pale Ale, and that really opened my tastebuds to every type of beer. Well, almost every type. I still don't love sours, and probably never will.
Well sour beers are something that are an acquired taste. Kinda like kraut, smelly cheese, or pickled herring. Back on topic killigans red and sam adams were the only choice in my area 12 years ago. Now there is a nice variety. But the gateway beer to craft beer was miller lite, after drinking that and then discovering something with flavor like sam or killigans it changed the whole perspective on beer.
