It's only my opinion, but don't put this over ice unless you increase the sweetness (and acidity?) a touch... My go-to sour serving is (essentially 'up') in a footed rocks glass, no ice. This recipe unmistakably lives up to its name.

Backed off the sugar syrup by 1/3. Cocktail was lovely. Nice hints of the cherry and Bourbon comes through. While it was nicely balance, would half the sugar to make the resulting cocktail a bit more sour.

I used homemade cherry brandy for this one and instead of the rich sugar syrup, I used some leftover cherry syrup from the brandy preparation process. Turned out to be Awesome!

Doesn't need the simple syrup, delicious all natural cherry bomb

This was a lovely cocktail. It's a little sweet, but it works. We really like the cherry flavor.
