Strike a balance between spirituous strength, citrus acidity, herbal complexity, bitterness from the aromatised wine and rich chocolate, and this cocktail...
The following variant works for me; the Cocchi Americano brings a pleasant bitterness, with a note of cinnamon: 1.5 oz gin, 3/4 oz Cocchi Americano, 1/2 oz crème de cacao, 1/2 oz lemon juice.
