In this episode of Sake Deep Dive, Jim and Andy tackle koshu-the history and culture of aging sake. Once more, our intrepid geeks go back to the early days of sake to see just what age does to our favorite beverage. We discuss the ancient history of aging sake, the Lost Century that saw the practice fade, and a little about its recent resurgence.
