Strega (or Liquore Strega), is an Italian herbal liqueur produced since 1860 by the S. A. Distilleria Liquore Strega in Benevento, Campania, Italy. Its yellow color comes from the presence of saffron in its recipe. Liquore Strega is 80 proof (40%) and among its approximately 70 herbal ingredients are mint and fennel. Strega is considered a digestif, meant for drinking after meals. Strega is the Italian word for "witch". I love this so much - very tasty!
