An amaro (that’s Italian for bitter) is a bittersweet, herbal Italian digestif. It is typically made by infusing 90% alcohol with a combination of herbs and bitters, then diluting the infusion such that the alcohol content of the final product falls between 16% and 40 %. Most homemade amari are diluted with simple syrup, but more nuanced products are diluted with water then sweetened via aging in oak wine barrel’s.
