Buffalo Trace Distillery Tested The Effectiveness Of 5, 10, and 15 Gallon Barrels for Aging Bourbon Whiskey. Chuck Cowdery's article about that experiment, published in his American whiskey newsletter, The Bourbon Country Reader, caused a sensation, especially among the micro-distillers who swear by small barrels. This small book includes that original article as well as some additional, related material. Some of it is new and appears here for the first time. It is being published as an ebook for the benefit of people who want to read it, but don't want to shell out for a subscription to the newsletter. The community of people who have an interest in this sort of thing is small but ardent. This seems to be the best way to make it available to the greatest number of people without just giving it away as a blog post.
