Beer festivals are all the rage, especially in Pennsylvania, and it's not like they've ever not been cool, but as the years go by, it seems as if beer festivals are becoming even more popular and celebrated. "Beer festivals not only offer attendees the chance to sample numerous brews (sometimes even rare and one-off pours)," USA Today notes, "but also allow beer fans to get to know their favorite brewmasters, sample paired foods, and learn all about beer and brewing." The Homebrewers Association points to one of the very first beer festivals being held in 1810, when "Bavaria's King Maximillian I. Joseph declared a 2-day festival in mid-October to celebrate the wedding of his son, Prince Ludwig to Princess Therese."
