Burton Baton
One of the good things (the one good thing?) about spending time in Delaware is that Dogfish Head is the local beer.
The greater Philadelphia area in general is great for craft beer, with lots of small brewers starting all the time, and established high-quality breweries such as Victory and Tröegs close by.
My new favorite beer is Dogfish's Burton Baton a 10% abv oak-aged imperial IPA
From the site: "For Burton Baton we first brew two 'threads' or batches of beer: an English-style Old Ale and an Imperial IPA. After fementating the separate beers in our stainless tanks, the two are transferred and blended together in one of our large oak tanks. Burton Baton sits on the wood for about a month."
As Mike says, it's an "ender" in that after a glass of Burton you're pretty much set drink-wise for a while - it ain't no session ale.
