FAQs:

What are bitters?

Bitters are made by infusing alcohol with botanical extracts such as bark, roots, and berries. Typically, they are used in small quantities (think a few dashes) to flavor different cocktails. While including bitters can be an acquired taste, they can greatly enhance the flavor profile of many cocktails. Bitterman says, “Bitters are to cocktails as salt is to food.” You can read more about bitters and their uses in the Epicurious article: What Are Bitters and How Should I Use Them?

What are the ingredients in a traditional Old Fashioned?

A traditional Old Fashioned is very straight forward. Dissolve a small amount of sugar in a bit of water in the bottom of a rocks glass (or use a dash of simple syrup). Add a few dashes of bitters. Pour in a few ounces of bourbon or whiskey to the glass, and stir the ingredients. Adding ice is optional, as is a citrus twist.
