I've had many of their beers, and never found a bad one. They're all drinkable, and some are outstanding. The McHenry is a damned fine CAP, the Oxford Organic Amber is a tasty pounder, and Holy Sheet is a really good interpretation of Belgian-style Abbey Ale.
The only one I've had I didn't particularly like was Loose Cannon. I found it unpleasantly unbalanced, but I'm not a hophead; the green mist that attacked me when I opened the bottle probably put me off. If you're into hopsmacks, you'll probably like it.
