Classic Martini Recipe

This 6:1 gin-to-vermouth formula produces a spirit-forward but balanced dry martini. It gives the gin enough structure to remain the focus while the vermouth contributes herbal, floral, and lightly bitter notes.

What You Need

• A mixing glass or sturdy pint glass
• A long-handled bar spoon
• A julep or Hawthorne strainer
• A chilled coupe, Nick & Nora glass, or martini glass
• A jigger or measuring tool
• Fresh, firm ice

Use a gin whose botanicals you enjoy neat, because the finished drink contains no juice, syrup, or other ingredient to conceal its character. A classic London dry gin gives a juniper-led result, while a softer contemporary gin can make the same ratio taste more floral or citrus-driven.

How to Make It Step by Step

1. Chill the glass

Place the serving glass in the freezer for at least 10 minutes, or fill it with ice and cold water while you prepare the drink. Discard the temporary ice water before straining. A cold glass slows warming and keeps the final sip closer to its intended dilution.

2. Measure the ingredients

Add 60 ml of gin and 10 ml of dry vermouth to the mixing glass. Measuring matters more than relying on a free pour: adding only 5 ml of vermouth produces a much drier drink, while 15–20 ml creates a softer, more aromatic martini.

3. Add plenty of ice

Fill the mixing glass with solid ice, ideally reaching nearly to the top. Large, dense cubes are preferable because they chill efficiently while melting more slowly than small or cracked ice.

4. Stir for controlled dilution

Stir smoothly for 20–25 seconds, keeping the spoon against the side of the glass. The aim is a cold, silky drink with roughly 15–20% water added through melting. Shaking introduces more air and can create a cloudier, colder drink, but stirring is the traditional method for a clear, polished martini.

5. Strain and garnish

Strain into the chilled glass immediately. For a lemon version, express a strip of lemon peel over the surface by twisting it skin-side down, rub the peel around the rim if desired, and drop it in or discard it. For an olive version, add one or two chilled green olives on a pick.

Martini Ratios Compared

“Dry” traditionally refers to using less vermouth, not to adding a dry ingredient. The best ratio depends on whether you want a sharp, spirit-heavy drink or a more integrated aperitif-style cocktail.

If you are unsure where to begin, use the 6:1 version. It is dry enough to feel classic without reducing the vermouth to a barely detectable rinse.

How Much Dilution Is Right?

Dilution lowers the drink’s alcohol intensity and integrates the gin and vermouth. A useful target is approximately 15–20% added water by volume. For the 70 ml recipe above, that means roughly 10–14 ml of melted ice water, producing about 80–84 ml before the garnish.

This is a target rather than a requirement. Ice temperature, cube size, mixing-glass shape, and stirring speed all change the result. Instead of counting seconds rigidly, use three checks:

• Temperature: the outside of the mixing glass should feel very cold, often close to too cold to hold comfortably.
• Texture: the drink should pour smoothly rather than feel hot or harsh.
• Aroma: the gin should smell clear and expressive, not dominated by raw alcohol.

If the drink tastes hot and aggressive, stir it for another 5–10 seconds. If it tastes thin or watery, use larger ice, stir for less time, and chill the glass more thoroughly before making the next one.

Choosing the Garnish

Lemon twist

Choose a lemon twist when you want brightness and a clean botanical finish. The aromatic oils in the yellow outer peel are more important than the juice. Avoid squeezing lemon juice into the glass unless you are intentionally making a different cocktail.

Green olive

Choose an olive for salinity and a fuller, savory finish. A firm, plain green olive generally keeps the drink balanced. Blue-cheese-stuffed or heavily seasoned olives can dominate delicate gins, so use them only when you specifically want that flavor.

Gibson-style onion

A pickled cocktail onion turns the drink into a Gibson-style martini. Its vinegar and sweetness are more assertive than either lemon or a standard olive, making it a better match for a robust, juniper-heavy gin.

Glassware: Which Shape Works Best?

For temperature control, a smaller glass holding about 90–120 ml is usually more practical than an oversized cocktail glass. The recipe yields approximately 80–84 ml after dilution, leaving enough room for the garnish without creating a large warm surface.

Common Problems and Fixes

The martini tastes too harsh

The usual causes are insufficient dilution, warm ingredients, or a ratio with too little vermouth. Stir for another 5–10 seconds, use a properly chilled glass, or move from a 12:1 ratio to 6:1.

The martini tastes watery

Overstirring, small melting ice, or a warm mixing glass can add excessive water. Replace the ice, use larger cubes, and shorten the stir. Measure the vermouth carefully as well, because too much vermouth can be mistaken for over-dilution.

The drink has little aroma

Use a fresh lemon twist and express its oils over the surface. Also check the vermouth: once opened, dry vermouth is best refrigerated and used while its aroma is still fresh. A stale bottle can taste flat, oxidized, or muted.

The drink is too cold but still tastes rough

Coldness alone does not guarantee balance. The drink may need more dilution or a slightly higher vermouth proportion. Try the 6:1 recipe with a full 20–25-second stir rather than serving an under-diluted, very cold pour.

Quick Formula to Remember

For one classic martini, use 60 ml gin, 10 ml dry vermouth, plenty of ice, and a 20–25-second stir. Choose lemon for brightness, an olive for salinity, or a cocktail onion for a savory Gibson-style variation. Adjust the ratio before changing the gin: the gin-to-vermouth balance is the most effective way to tailor the drink.

Frequently asked questions

Can I make a martini without a mixing glass?

Yes. A sturdy pint glass can stand in for a mixing glass. Add the gin, vermouth, and ice, stir with a long-handled bar spoon, then strain into a chilled serving glass. A julep or Hawthorne strainer is listed as suitable for straining.

Should I refrigerate dry vermouth after opening it?

Yes. The article recommends refrigerating dry vermouth after opening and using it while its aroma is still fresh. A stale bottle can make a martini taste flat, oxidized, or muted, so fresh vermouth can help preserve the drink’s herbal and floral notes.

Can I use a contemporary gin instead of London dry gin?

Yes. The recipe can be made with a softer contemporary gin; the same ratio may taste more floral or citrus-driven. The article recommends choosing a gin whose botanicals you enjoy neat, since the finished drink has no juice, syrup, or other ingredient to conceal its character.

Why should I use a small serving glass?

A smaller glass helps with temperature control. The recipe yields about 80–84 ml after dilution, and a glass holding about 90–120 ml leaves room for garnish without creating a large warm surface. The article also notes that a smaller glass is more practical than an oversized cocktail glass.

Can I shake a classic martini instead of stirring it?

Yes, but stirring is the traditional method for a clear, polished martini. Shaking introduces more air and can make the drink cloudier and colder. For the article’s classic method, stir smoothly with ice for 20–25 seconds, aiming for a cold, silky drink with controlled dilution.
