Dry vs. Dirty Martini: What's the Difference?
Two Martinis, same base, very different vibe. A Dry Martini is crisp, botanical and barely there. A Dirty Martini is savoury, salty and unmistakable. Here's exactly how each one is built — and when to pour which.
The base they share
Both drinks are built on the same two ingredients: a base spirit (London Dry gin is classic, vodka is the modern default) and dry vermouth. The fork in the road is what happens next — and how much vermouth and brine go in the glass.
The Dry Martini
- Gin (or vodka)2.5 oz / 75 ml
- Dry vermouth1 dash to 0.5 oz / 15 ml
- GarnishLemon twist or olive
Stir with ice for 20–30 seconds, strain into a chilled coupe or Martini glass.
"Dry" refers to the vermouth ratio — the less vermouth, the drier the drink. A 6:1 gin-to-vermouth pour is a balanced modern Dry Martini; Hemingway-style "very dry" Martinis go closer to a whisper of vermouth. The flavour is clean and botanical, dominated by the base spirit, with a citrus or briny lift from the garnish.
The Dirty Martini
- Gin or vodka2.5 oz / 75 ml
- Dry vermouth0.5 oz / 15 ml
- Olive brine0.25–0.75 oz / 7.5–22 ml
- Garnish2–3 olives on a pick
Stir (or shake — see below) with ice, strain into a chilled glass.
The defining move is the splash of olive brine straight from the jar. It adds salt, umami and a subtle cloudiness. The amount sets the level:
- Lightly dirty — 1/4 oz brine. Salinity without committing.
- Standard Dirty — 1/2 oz brine. The version most bars pour.
- Filthy — 3/4 oz or more. Brine-forward, almost savoury.

| Garnish | Lemon twist or single olive | Skewered olives |
Shaken or stirred?
Classic technique is stirred — it keeps the drink silky, clear and properly cold without bruising the spirit. Shaking aerates and dilutes faster, which some bartenders prefer for a Dirty Martini because the brine integrates more quickly and the slight cloudiness suits the style anyway. For a Dry Martini, stir. For a Dirty Martini, do whichever you like — and ignore anyone who tells you there's only one right way.
When to pour which
Reach for a Dry Martini when you want the gin (or vodka) to do the talking — pre-dinner, with something light, or any time you'd otherwise sip a neat spirit. Reach for a Dirty Martini when you want something more food-like: alongside oysters, charcuterie, or as a standalone savoury sipper.
