Tentura (Greek: te?t???a) or tintura, from the Italian word for tincture, is a liqueur traditionally produced in the Greek city of Patras since the 15th century. It contains alcohol, water, sugar and fermented essences of cloves, cinnamon, nutmeg, and citrus fruits. Tentura is a quite dark shade of orange-red, hence its name. It is served chilled, in a small glass. It can also be added in espresso coffee, which is then called corretto. It is also served at room temperature. The alcohol it contains is from the nearby winery in Patras.
