Pertsovka is recognized for its flavoring with which spicy ingredient?

Pertsovka is a traditional Russian spirit known for its distinctive flavor profile, which is primarily attributed to the use of red chili pepper. This infusion provides the beverage with a notable spiciness and a vibrant heat that complements the base spirit, typically vodka. The red chili pepper is integral to Pertsovka's identity, enhancing its character and appeal.

In contrast, while ginger, black pepper, and cayenne are spicy ingredients used in various culinary contexts, they do not contribute to the signature flavor of Pertsovka in the same way that red chili pepper does. Each of these alternatives provides a different type of spiciness, either through warmth (ginger) or pungency (black pepper and cayenne), but none aligns with the traditional and recognized formulation of this particular spirit.
