Peppers, especially varieties like jalapeños, habaneros, and bell peppers, add a unique and often spicy dimension to cocktails. Their incorporation can range from muddling fresh peppers to infuse the drink with heat and flavor, to using pepper-infused spirits or syrups. The heat from peppers can provide a counterbalance to the sweetness and acidity often found in cocktails, creating a more complex and layered drinking experience.

In cocktails, jalapeños, for example, are commonly used to add a moderate heat level and a fresh, green flavor. Habaneros, with their higher Scoville rating, bring more intense heat and a fruity undertone, making them suitable for bolder cocktails. Bell peppers, though not spicy, can contribute a mild sweetness and a crisp, vegetal note. These elements make peppers versatile ingredients that can be tailored to enhance a wide range of alcoholic beverages, from margaritas and martinis to more innovative concoctions.
