I must add my list of favorites, in no particular order:
Hoosier Ma Stout from Rockbottom in Indianapolis. 13.2% alcohol, dark, and yummy.
Samuel Adams Chocolate Bock. $20 for one 20 oz bottle, but very much worth the price. Only brewed twice per year.
Guinness 225th Anniversary Stout
Leinenkugel's Oktoberfest
Leinenkugel's Northwoods (but they don't make it anymore).
Leinenkugel's Honey/Berry: Mix the Berry Weiss 50/50 with the Honey Weiss in a frozen pint glass, enjoy. This is probably the only way to drink more than one of the Berry's, they are very sweet.
There are many others, but these are the best for now.
