In the small town of Pottsville, Pennsylvania, visitors can find the oldest beer brewery in America; Yuengling & Son's, which had produced its first beer in 1829, and has since become iconic to beer enthusiasts up and down the eastern seaboard. The wonderful thing about this brewery, even though I don't actually drink beer myself, is that they give free tours year-round to those who make the pilgrimage. As a part of the tour, we were shuffled down flights of industrial revolution-era stairs, and into a huge, expansive cavern that stayed at a cool 50 degrees, year-round. With the temperature rising well above 85 outside, being in this dark, cool place was an absolute godsend. Fortunately for the founders of the Yuengling brewery, this natural cavern formation was also the perfect place, at the perfect temperature, to store beer. This hallway you see in this photo connects the Yuengling factory proper with the dark, stony walls of the cavern, where workers a hundred years ago rolled enormous barrels (Some of the smaller ones, you can clearly see!) of freshly-brewed ale from the pressure-injection room, down to be stored in the caverns below. Makes you thirsty, doesn't it?
