What is the garnish for a Gibson?

The garnish for a Gibson is cocktail onions. This classic martini variation is distinguished not only by its use of gin and dry vermouth but also by the specific garnish that accompanies it. While olives are commonly used in traditional martinis and cherries are typically found in drinks like Manhattans or other sweet cocktails, the cocktail onion adds a unique flavor profile that complements the dryness of the gin in a Gibson.

Using cocktail onions provides a subtle, slightly sweet and tangy flavor, enhancing the overall tasting experience of the drink. This specificity of garnish is what sets the Gibson apart and makes it recognizable on a cocktail menu.
