What is one of the four main groups of aromatized wines?

Vermouth is one of the four main groups of aromatized wines, which are wines that have been flavored with various botanicals, including herbs, spices, and other plant materials. These additives impart complex flavors and aromas, enhancing the wine's profile. Vermouth specifically has two primary styles: dry and sweet (or sweet red), and it is often used as an aperitif or in various cocktails, such as the classic Martini and Negroni. The use of fortified wines and the addition of aromatic herbs and spices make vermouth a unique and versatile category within the larger world of aromatized wines.

The other options do not fall within the recognized categories of aromatized wines. Fruity spritzers and cocktail mixers are more associated with mixed drinks or low-alcohol beverages and do not specifically reference a type of wine. Sweet wines, while they do exist and can be flavored, do not qualify as aromatized wines unless they are infused with botanicals, which is not the primary characteristic of typical sweet wines.
