What is the difference between an Ale & a Lager?

The basic difference between these two major beer styles is how they are fermented. Ales are fermented with top-fermenting yeast at warm temperatures (60-70F), and lagers are fermented with bottom-fermenting yeast at cold temperatures (35-50F).

What is the oldest beer we have on tap?

With 40 taps that are regularly interchanging with different beers, cocktails, and wines, our customers get to constantly try new beers they may not normally get to at other places. We have been lucky to put Yuengling on tap, which is the oldest beer we have on tap. D. G. Yuengling & Son is the oldest operating brewing company in America, established in 1829. Below are some fun facts about Yuengling & Son Brewing Co.:

What gives beer its different shades of color?

Grain is by far the strongest coloring agent in beer, and grains are colored by melanin, a rust-red pigment that drives the color of beer. Two chemical reactions make grains go from pale yellow to jet black: Maillard reactions and caramelization. An under-appreciated contributor to beer color isn’t even an ingredient: it’s time. As beer ages, particles in suspension within the beer – yeast, polyphenols, etc. – begin to fall to the bottom of the vessel. The remaining beer will reflect less light, making it appear darker.
