We will taste it in the best possible scenario: a XIX century historical tavern. Vermouth on tap is white wine flavored with botanicals such as: wormwood, vanilla, ginger, licorice, cinnamon, lemon balm, coriander and many more. It has been the aperitif of Madrid for over a century. It comes on tap and it is served on the rocks. In America, vermouth is used as a cocktail ingredient but in southern Europe it is drunk straight.
