Chase Parham and Steve Thomason are back with another episode of Bourbon South, and this week the topic is Pappy Van Winkle. Andy O'Bryan of Yalobusha Brewing Company is our tour guide as we sample four different Van Winkle bottles -- 10 year, 12 year, 15 year and 20 year. We discuss the secondary market, the bourbon craze and how Van Winkle became the one of the keynote brands associated with this craze.
