The full title of this book is "The Social History of Bourbon - An Unhurried Account of Our Star-Spangled American Drink".
I recently picked up a used copy of the book at Commonwealth Books' Milk Street shop, while stranded in Boston for a bit after a flight cancellation.
This book is an excellent read - the author has a nice easygoing and very readable style. He does a great job of mixing exhaustive research with a dry wit. If you can grab a copy for a few bucks, it is well worth the read, despite being relatively dated.
My favourite chapters are "Whiskey Fun and Folklore" and "The Swinging Door", which relates some interesting stories about the last of the pre-prohibition saloons.
