I’m not sure if this is a dry vermouth because it tastes quite sweet. However, the Lustau white/blanco is a white vermouth full of character with much bitterness, sweetness and tartaric acid at the same time and spicyness. Very much like a neat cocktail of its own, it is very good in any kind of drinks asking for dry or white/bianco vermouth. Consider to reduce the amount of bitters when using the Lustau because it contains already much bitterness of vermouth and probably also cinchona.
