During our first morning in Kilkenny, we were awoken by loud and successive clanging. My wife asked with irritation, “What is that rude noise?” My answer was, “That is an Irish wake up call.” This time-honored tradition happens when barkeeps roll out empty beer kegs so they can be replaced by a delivery truck. You would think based on how the Irish love their pints, they would adopt the U.S. standard of 15.5 gallons verses their 13.2 gallon size.
