It all started when we heard a rumor about someone mixing an entire half barrel of Wisconsin Old Fashioneds for a fishing trip.

We thought it was a brilliant idea and naturally had to try it ourselves. First, we needed to work out the recipe proportions so we didn't end up with 15.5 gallons of undrinkable sludge.

Conveniently, we already owned a 1.75-gallon keg from a short-lived beer brewing endeavor.

We decided to scale up our favorite Whiskey Old Fashioned Sour recipe to fit the keg.

To our delight, the keg could hold full bottles of whiskey and soda, making the mixing process very easy with little measuring. We then connected CO2 to maintain the carbonation and propel the cocktail.

Finally, everything was assembled in a cardboard box.

Together, we had our first taste.
It was GLORIOUS!
