Rhubarb Cocktail Bitters from Fee Brothers

• $6.49
• Kegworks

Fee Brothers bitters are a bar staple for me — just a dash of bitters, with their herbal notes and flavors, dress up plain soda water into a refreshing summer treat. This essentially nonalcoholic rhubarb version is an especial favorite; I love the tangy sweetness it lends to soda water.

Also available in many local grocery stores and wine and liquor shops — most likely for a better price than the one listed here.
