Make a quick old-fashioned cocktail with this easy syrup that already has bitters added into the mix. Great for making batch cocktails. Makes 8 ounces, equal to about 16-32 cocktails (depending on how sweet you like your old-fashioneds).
In a medium saucepan, combine water and sugar over medium heat and stir until the sugar has dissolved.
Remove from heat and let cool completely. Then stir in the bitters.
To make 1 old-fashioned: Add ¼ to ½ ounce of syrup to a rocks glass. Top with 2 ounces of bourbon. Add a large ice cube and garnishes.
For a pitcher of old-fashioneds (about 12 drinks): Pour 750 mL whiskey into a quart-sized pitcher. Stir in ¾ cup old-fashioned simple syrup with a wooden spoon. (You will have leftover syrup.) To serve, pour ~2½ ounces into rocks glasses with large ice cubes.
