The Martinez is a classic cocktail made with gin, sweet vermouth, maraschino liqueur, and bitters. It is believed to be the predecessor to the modern-day Martini.
Martinez recipe
Stirred over ice, strained into a chilled glass, garnished, and served up.

The Martinez sits in the family tree between the Manhattan and the Martini, but it drinks like neither exactly. It is rounder, softer, and more perfumed than a dry Martini, with a gently sweet core from vermouth and maraschino. Orange bitters keep it from feeling heavy, while the gin adds structure and a herbal spine.
If you want it leaner, use a more juniper-forward gin and go easy on the maraschino. If you prefer a richer, old-fashioned style, choose a fuller vermouth and garnish with a cherry.
The Martinez is widely considered a 19th-century precursor to the Martini, though the exact origin is debated. One popular story links it to the town of Martinez, California; another ties it to legendary bartender Jerry Thomas, whose 1887 book includes a Martinez recipe. Early versions varied quite a bit, often using Old Tom gin rather than drier modern styles, which helps explain why recipes differ from bar to bar today.
This is a strong, spirit-forward drink, but it should never taste sharp. Serve it very cold in a stemmed glass and pair it with salty snacks, olives, nuts, or cured meats. It works especially well as a slow first drink of the evening.
For a non-alcoholic nod to the style, stir together a zero-proof gin alternative, a non-alcoholic red vermouth-style aperitif, and a dash or two of orange bitters alternative over ice, then strain up and finish with a lemon twist.
