If you want a bit more oomph to your Old Fashioned, then how about adding a bit of coffee. For this Cold Brew Coffee is the trick, added to Bourbon, Simple Syrup, Orange Bitters, Angostura Bitters & a good dash of Chocolate Bitters.
Build all ingredients in mixing glass. Stir with ice until chilled. Strain into Old Fashioned glass
