Blanc Quinquina is a pale, wine-based aperitif flavored with quinine from cinchona bark.
Quinine bitterness on a light wine base, and quinine is what separates it from a vermouth — swap one in and you get wormwood instead. A dash of a quinine bitters over a pale vermouth closes most of the distance.
Americano and bitter vino (bitter aromatized wines)
The neighboring shelf: the bitterness comes from gentian and wormwood rather than quinine, and the wine is usually colored. In a spritz they lead — herbier, rounder, darker — where a quinquina stays dry and sits under the wine.
Dry/white vermouth
Vermouth must be aromatized with wormwood, and that is the whole distinction. They look alike and get used alike, but swap one in and the drink trades a quinine dryness for a herbal one.
Refrigerate after opening and use within six weeks — it oxidizes and fades faster than spirits do.
