I've tried their Winter Lager, Boston Ale, and Oktoberfest beers. I liked all three...I think I've only had the Boston Ale on draft. The cherry and cranberry things violate one of my primary rules of alcohol consumption. Fruits are for Wine and Grains are for Beer.
I wouldn't say any of their beers are my favorites, but they are high on my list of bottled beers available nationwide. I travel quite a bit, and the locally brewed beers are usually my preference. When I'm home, I like a Molson or Moosehead if I'm in the mood for a lighter brew, but mostly I just drink Guinness.
