They made Ice Cream. Apparently there is some sort of crossover somehow.
They haven't for about 20 years but I grew up in Pottsville, PA and you'd always see all sorts of Yuengling Ice Cream Signs, etc.
Having cut my teeth on Yuengling, I have to say in my opinion Lager is not really my favorite. I think outside the area it is way overpriced. Premies are pretty good and way cheaper. They bottle a version of Yuengling Black and Tan that is half Premium and half Porter, but if you want a real treat have a true Yuengling Half and Half (Black and Tan, if you will) by mixing Yuengling Lord Chesterfeld Ale and Yuengling Porter.
In my opinion Chesties (Lord Chesterfeld Ale) are the best they make.
