THe PA Yuengling brewery is up in the mountains here. I've gone out for the tour and it was a good time except when they yelled at me for catching beer in my hands that was over flowing from the cans during processing. The most interesting thing was the main section of the brewery with the vats. The brewery was originally built before electricity was commonly available so the brewery has a stained glass ceiling. This provided light in the brewery and cut down on glare from the light reflecting off the early polished copper vats that caused problems for the brewery workers. The PA brewery also has a nice sized bar in it that is used for taste testing but was originally the employee bar where employees drank for free till the drinking and driving laws created liability issues for yuengling.
