Tom, Firestone - their Double Barrel Ale, in particular - has been a popular one down here for years. Based on the ones I've had (3-5 styles, I forget) I would agree that they tend towards the dry side, herbal hops featured. I don't buy them, but a friend does.
Last night I had Jake to myself while the old lady was at night school. So we went to happy hour at a local brewery, of course. The waitress was not amused, I fear.
Anyways, BJs porter is still one of my all-time fave beers. Black as night, persistent dense head of foam, creamy mouth feel, chewy malt flavors, drying bitterness from burnt barley, with a long finish balanced between malt sweetness and black patent. I think they use nitrogen from the tap, too. Very corporate place nowadays, but that beer is still divine, based on last nights sample.
Never been disappointed with their porter.
