Martini L'Aperitivo Rosso is a sweet red vermouth made by Martini & Rossi in Italy. It is based on a recipe from 1863 that blends selected wines with Italian herbs, and natural caramel gives it a scarlet color. It is bottled at 15% ABV and sells for around $14 to $18 in the US.
And it’s a credible and versatile vermouth that is fine on its own — more sweet than bitter, with notes of cinnamon, vanilla, citrus peel, and a moderated gentian character.
