Which of the following vermouth styles is noted for its usage with traditional cocktails?

The correct answer is Lillet because it is a fortified wine often used in classic cocktails, particularly known for its role in drinks like the Vesper Martini. Lillet has a distinctive style that combines crispness and a touch of sweetness, making it a versatile ingredient that complements a variety of spirits, especially gin and vodka.

This versatility has contributed to its widespread use in traditional cocktail recipes, allowing it to enhance both flavor and complexity.

Other options like Cocchi Americano, though unique and potentially used in cocktails, do not have the same historical significance or frequency of usage in traditional cocktails as Lillet. Similarly, Primitivo quiles is not a style commonly recognized or used in cocktail-making, while Byrrh, while having its place, has not achieved the same level of recognition in iconic cocktails compared to Lillet. Therefore, Lillet stands out for its established role in traditional cocktail culture.
