Since I travel a bit, I like to search for the 'best' of certain things. Craft beers is one of those. Dogfish Head in Delaware is certainly top 3 in the ones I've tried so far. Their beers are very flavourful and robust. They have some interesting wood aged beers - Palo Santo Marron was the one that made me a big fan. It is dark, 12% (or there abouts) and incredibly good.
If my daughter can make it east we'll do tastings at Troeg's (30 minutes from me), Dogfish Head, then Flying Dog (which I've never had).
EDIT: You don't have to drink it warm. I don't. I drink it out of the fridge.
