I'm looking for distributors/shops close to central Pennsylvania that sell Okocim beers such as Okocim Porter, Okocim Beer, or Okocim Mocne. I've seen O.K. Beer around here (another Okocim product), but the branded Okocim beers are what I'm really interested in. I don't mind driving a bit either, but hopefully something in or around the state...
Okocim Beer is part of the Carlsberg group. According to Carlsbergs site it looks like they are distributed in the USA by St. Killian.
St. Killian has a beer finder page that lets you search for bars, resturants, or stores that sell particular products by zip code. When typing in the zip code for State College, Pennsylvania, I'm not sure where you are located but this is pretty central, it shows four locations within 100 miles.
You could put in your zip code and then select see what is near. I'd call before making the trip and see which Okocim beers they actually sell since the comments seem to suggest that some only carry O.K..
