Somewhere along the way, gin got replaced by vodka in the martini. That was a mistake.
A vodka martini is fine - unoffensive, clean, easy to like. But a gin martini is the actual drink. The botanicals do something in vermouth that vodka simply can’t. The juniper, the citrus, the herbal depth - it all comes together in a way that makes the cocktail worth drinking slowly instead of just getting through it.
This gin martini recipe covers the classic build and the dirty variation. The right gin, the right ratio, and the details that make a perfect gin martini worth ordering twice.
Essential Gin Martini Ingredients
In fact, the ingredients for this cocktail are quite simple. But it is precisely this carefully curated list that allows you to savor every sip:
-
Gin. The main character here. About 60ml, or two ounces. The botanicals are going to be front and center - this is not a drink that hides anything. That’s exactly why we make Devil’s Grin the way we do: 14 botanicals, each macerated separately, so every note shows up clearly in the glass. In a martini, that kind of layering matters.
-
Dry vermouth. This is where most home bartenders go wrong. Vermouth is not optional, and “just wave the bottle near the glass” is a joke that produces a worse drink. Start with a 5:1 ratio - 60ml gin to 12ml vermouth - and adjust from there. Vermouth adds a herbal, slightly bitter complexity that makes the drink cohesive. Without it, you’re just drinking cold gin.
-
Ice. Use large, dense cubes if you have them. Slow-melting ice gives you more control over dilution.
-
Garnish. Lemon twist or olive, BUT not both. A twist adds aromatic brightness. An olive adds a faint salinity. Pick one based on which direction you want to go.
For a dirty version, you’ll also need olive brine - a splash, not a pour (more on that read below). These are your gin martini ingredients. Resist the urge to add things.
Choosing the Best Gin for Martini
The best gin for a martini is one with enough character to carry the drink but not so much going on that it becomes chaotic.
Classic London Dry gins work well because they’re assertive and clean - juniper forward, with citrus and a dry finish. The vermouth has room to work alongside them without competing.
Devil’s Grin is worth trying here. Fourteen botanicals, including toasted mesquite from South Texas and cardamom from Guatemala, give it a complexity that holds up in a stirred drink. The layers - juniper up front, spice and citrus behind it - come through clearly when there’s nothing masking them. That’s exactly what a martini asks of a gin.
Avoid anything too floral or heavily fruit-forward for a classic martini. Those gins are fine cocktail ingredients, but the martini format tends to amplify whatever is dominant in a gin, and a very sweet or perfumed bottle can go sideways quickly. If you love a floral gin, try it first with a wider vermouth ratio and see how it lands before committing to a full build.
How to Make a Gin Martini: Classic Recipe
This is how to make a gin martini that’s actually cold, properly diluted, and worth drinking.
What you need:
-
60ml gin.
-
12ml dry vermouth.
-
Ice (large cubes or cracked).
-
Lemon twist or olive to garnish.
The process:
Chill your glass first. Put it in the freezer for ten minutes, or fill it with ice water while you build the drink. A warm glass ruins a martini faster than anything else - the drink warms up immediately, and you lose the whole point.
Add ice to your mixing glass - fill it about two-thirds. Pour in the vermouth first, then the gin. This order doesn’t change the drink chemically, but it forces you to measure the vermouth accurately rather than eyeballing it at the end.
Stir, not shake. The stirring-versus-shaking debate has been exhausted, but the short version is this: shaking introduces tiny air bubbles and over-dilutes a drink that relies on its texture. A stirred martini is silky. A shaken one is watery and slightly cloudy. Stir for about 30 seconds - longer than you think you need to.
Strain into the chilled glass. If you’re using a twist, express the lemon oil over the surface of the drink by bending the peel skin-side down over the glass, then run the outside edge around the rim and drop it in. If you’re using an olive, spear it and drop it in.
This classic gin martini recipe doesn’t need improvement. The only variable worth adjusting is the vermouth ratio based on your taste. Try it at 5:1 first. If you want more botanicals, go to 4:1. If you want drier, pull back slightly - but don’t go below 8:1 unless you’re making a statement rather than a cocktail.
The gin martini recipe is a ratio, not a fixed measurement. Scale it up or down, but keep the proportions.
A perfect gin martini is about temperature as much as anything else. Cold glass, cold mixing glass, cold gin if you store it in the freezer. Warmth is the enemy.
Dirty Gin Martini Variation
The dirty martini divides people. Gin purists find it excessive. People who love it really love it.
Here’s what changes: you add olive brine to the mix, which makes the drink cloudier, saltier, and more savory. It softens the gin’s botanical edge and pushes everything in a briny, almost food-like direction. Some people find this more approachable than a straight classic. Others think it covers up the gin, which is the whole point.
For a dirty gin martini recipe, use the same 60ml gin and 12ml vermouth, then add 15-20ml olive brine. Stir with ice, strain, garnish with olives - and here, the garnish matters more. A plain olive is fine. A blue cheese-stuffed olive is better. The funk of the cheese picks up the salinity of the brine and the botanicals of the gin in a way that works surprisingly well.
Cocktail onions are another option - that variation is technically called a Gibson, but the principle is the same. Savory garnish, savory drink.
The gin martini in its dirty form is a different experience from the classic. Not better, not worse. Just a different conversation with the same base ingredients.
One thing stays constant in both versions: quality gin, proper temperature, and enough restraint not to overload a drink that was designed to be simple.
