I used to like Rolling Rock because it was a clean, simple taste but refreshing. It was bought out by a larger brewing house (forget which one) and maybe it's my imagination, but I can detect a different taste which makes it seem more like every other mass-produced beer, in other words, it's still drinkable but nothing special anymore.
There's a New Orleans beer I used to like but I don't even know if they make it anymore, esp. post-Katrina. Dixie or something?

I'm so knowledgable. lol
I do like Sam Adams' wheat ale.
