Spent most of my life in Wisconsin and observed this: When it comes to brandy old fashioneds bartenders in Wisconsin tend to offer 3 options: sweet, sour, or press. Korbel is the most popular brandy in Wisconsin for old fashioneds and will go with that by default, but people have widely differing opinions on whether to use sprite, 7-up, squirt, or 50/50. Basic maraschino cocktail cherries are generally preferred over luxardo or similar.
