9. D.G. Yuengling and Son Brewery – Pottsville, Pennsylvania
Known as America’s oldest brewery, this Schuylkill County establishment has been brewing since 1829. Travelers can step back in time as they explore the hand-dug fermentation caves used to store beer before modern refrigeration. Thirsty travelers can also savor some samples in the basement tavern built under the former Pottsville city hall. Complimentary tours operate Monday through Saturday.
