Liquore Strega Is an 80 proof herbal concoction, with a reputed 70 ingredients. Amongst those ingredients include mint, saffron and fennel. Strega is a bright yellow, nearly fluorescent yellow. It is saffron that gives it this color. Swirling the liquor in a glass shows it to be a nearly viscous syrup. Strega is a very complex drink. It starts sweet from the sugar, but then it becomes very bitter from the herbal components. The tail end of drink finishes with a strong liquorice flavor, most likely coming from the fennel.
The story behind Strega is interesting as well. In 1860, Giuseppe Alberti found monks from Benevento, Campania who made this liquor. Promising to do nothing but good with the recipe he coaxed the secret recipe from them. At first he sold it as a medical elixer (as many liquors were). Sales were poor. Smart businessman that he was, he decided to sell it as a liquor instead. He renamed it to Liquore Strega, which roughly translates to liquor of the witch. From there, the sales took off.
