Wisconsin Old Fashioned
The bane of contemporary mixologists’ existence, the Wisconsin Old Fashioned, is alive and well-- muddled fruit and sour mix be-damned. Wisconsinites LOVE their Old Fashioned and arguably single handedly kept the Old Fashioned alive for decades before it came back in style in the early 2000s. The state also arguably single handedly brought Korbel California Brandy to success by way of their allegiance to the spirit over whiskey.

The primary differences between a Wisconsin Old Fashioned and the rest of the country’s Old Fashioned are:
A. the muddling of fruit and sugar cubes.
B. The inclusion of soda, citrus soda, and/or sour mix
and C. The aforementioned use of brandy over whiskey (Spirits/Cocktails)
