The Straub Brewery in St. Mary’s, PA has several good beers plus season beers, bock beer, craft beers, etc. They set up special days at bars and beer distributors all around the state.
The flagship beer is a 1880’s recipe that has a distinct taste not found in the mass-produced swill. I liked it a lot before I quit drinking.
Check out their website. If you go there, they have the Eternal Tap where you can have a few free glasses.
