Ginger syrup is a sweet and spicy liquid made from fresh ginger, sugar, and water. It is commonly used as an ingredient in a variety of cocktails to add a distinctive, warming kick. The syrup's bold ginger flavor pairs well with a wide range of spirits, making it a versatile addition to any mixologist's arsenal.

In the context of alcohol, ginger syrup is particularly popular in cocktails that benefit from a touch of spice, such as the Moscow Mule or the Dark 'n' Stormy. By infusing the drink with a concentrated ginger essence, the syrup elevates the overall flavor profile, providing a complex, aromatic experience. Its thickness also helps to balance the acidity and bitterness of other cocktail ingredients, ensuring a well-rounded and harmonious drink.
