Badger, I tried out that beer in Gettysburg, in that tavern in the basement below the Dobbin House. It was very good.
Regarding the Rev Dobbin, I wonder how that minister from "Ireland" (I would bet dollars to donuts he was from Antrim), made all his money to build such a fancy house back in the 18th century. Did they have the functional equivalent of televangelists in the 18th century?
A real favorite of mine for 20 years. I'm glad America's Oldest Brewery (in continuous operation) is growing as a regional brew. They've earned it.
If at all possible try their Porter. It's not commercially pushed as heavily as their Lager or Black and Tan, but in terms of pure craftsmanship its their masterpiece.
