Glenn Howerton, Rob McElhenney, and Charlie Day know a thing or two about bars — those four walls wherein people connect, celebrate, and escape their troubles for a while. Like the fictional Paddy's Pub where their It's Always Sunny in Philadelphia characters congregate, their Four Walls whiskey is both Irish and American. It's a blend of grain and malt Irish Whiskeys from Great Northern Distillery in Dundalk, Ireland, and bold American Rye from Cedar Ridge Distillery in Iowa. The resulting whiskey brings out the best in both, resulting in a drink that's great on its own, in a cocktail, or as a beer-chased shot, and recently won a Gold Medal at the 2024 San Francisco Spirits Competition.
