Lots of great choices. Just about anything that comes from Belgium is awesome, Most Sam Adams brews are good and in the hot summer few can beat a Corona w/lime.
Onto the worst of the worst ... I nominate Drummond brothers (wonder if they are still in biz). In college a 24 pack cost about $10 and that was about $9.99 overpriced. It tasted like someone fermented the leftover scraps from a deli grill at the end of a busy day --- yummmmmy
Best,
