What is the correct garnish for a classic Martini?

The classic garnish for a Martini is an olive or a twist of lemon peel. This choice is rooted in tradition and serves both aesthetic and functional purposes. The olive adds a touch of brininess that can enhance the drink's overall flavor, while the lemon twist provides a hint of citrus aroma, which complements the botanicals in the gin or the flavor notes of the vodka.

Using an olive as a garnish is particularly iconic for gin-based Martinis, often associated with the classic dry style. The twist, on the other hand, is favored by those who prefer a less pronounced flavor, allowing the spirit to shine while contributing a fragrant element. Both garnishes are widely accepted and recognized among bartenders and drinkers alike, making them the quintessential choices for this timeless cocktail.
