Types of Cocktail Shaker and How to Choose One for Ready-Made Mixers

There are three main types of cocktail shaker: the Boston shaker, the cobbler shaker and the French shaker. For most home hosts using ready-made mixers, a cobbler shaker is the easiest place to start because it has a built-in strainer and needs no extra tools. A Boston shaker suits people who make drinks for groups often and want speed and a strong seal. A French shaker sits between the two, with a simple, elegant two-piece design. Whichever shaker you choose, the most important rule is the same: shake still mixers such as sour mix, juice and syrup, but never shake fizzy mixers such as tonic, soda or ginger beer in a sealed shaker.

What are the main types of cocktail shaker?

A cocktail shaker is a sealed container that chills, dilutes and blends a drink by moving the liquid hard against ice. The types of cocktail shaker differ in how many parts they have, whether a strainer is built in, and how easily they seal and open.

Shaker type	Parts	Built-in strainer?	Best for	Things to watch
Boston shaker	2: a large metal tin plus a mixing glass or a smaller metal tin	No, a separate strainer is needed	Regular hosts, larger batches, egg white or aquafaba drinks	Takes a little practice to seal and separate
Cobbler shaker	3: a tin, a strainer top and a cap	Yes	Beginners, small gatherings, quick single drinks	The lid can stick when very cold; the strainer holes can be awkward to clean
French shaker	2: a metal tin and a fitted metal cap	No, a separate strainer is needed	Hosts who want a tidy, stylish shaker without the glass part	Fewer models available; the cap can also stick when cold

Boston shaker

A Boston shaker is a two-piece shaker made of a large metal tin and either a pint-style mixing glass or a smaller metal tin that fits inside it. The version with two metal tins is often called tin-on-tin. When cold liquid and ice go in, the metal contracts slightly and the two pieces lock together, creating a firm seal. You open it by tapping the side of the large tin where the two pieces meet.

The Boston shaker has plenty of room, so it handles two drinks at once more comfortably than many small shakers. The glass version lets guests see the drink being made, but glass can chip or break, so the all-metal version is the safer choice for busy gatherings. Because there is no built-in strainer, you will also need a separate strainer.

Cobbler shaker

A cobbler shaker is a three-piece shaker with a metal tin, a lid that has a strainer built into it, and a small cap that covers the strainer. You fill the tin, put the lid and cap on, shake, then remove only the cap and pour through the built-in strainer.

The cobbler shaker is the most beginner-friendly of the types of cocktail shaker because everything you need is in one unit. It is a good fit for a dinner for a few friends, when you are making one or two drinks at a time from a ready-made sour mix or margarita mix. Its main drawbacks are that the lid can freeze tight after a long shake, and the small strainer holes can let ice shards through or trap pulp, which makes cleaning more fiddly.

French shaker

A French shaker, sometimes called a Parisian shaker, is a two-piece shaker made of a metal tin and a fitted metal cap that slides over the top. It looks a little like a cobbler shaker but has no built-in strainer, so you pour through a separate strainer, as with a Boston shaker.

A French shaker appeals to hosts who like a sleek look on the table and want fewer parts than a cobbler, without handling a glass. It is less common in shops, so you may have fewer sizes and styles to choose from.

Which strainer do you need with each shaker?

A strainer is a tool that holds back ice, fruit pieces and herbs as you pour a shaken drink into the glass. A cobbler shaker already has one in its lid, while a Boston shaker and a French shaker need a separate strainer.

Hawthorne strainer: a flat strainer with a metal spring around the edge. It sits over the mouth of a metal tin and is the usual partner for a Boston or French shaker.
Julep strainer: a perforated, spoon-shaped strainer that fits inside a mixing glass. It is more often used for stirred drinks than shaken ones.
Fine mesh strainer: a small, cone-shaped sieve held under the main strainer. Using both is called double straining, and it catches tiny ice chips and pulp for a smoother drink. It is useful with ready-made mixers that contain fruit purée or pulp.

How do ready-made mixers affect your choice of shaker?

Ready-made mixers are prepared bases such as sour mix, margarita mix, cocktail syrups, juices, tomato-based mixes and fizzy drinks like tonic or ginger beer. Some of them gain a lot from shaking and some should never go in a shaker, so the mixers you buy most often should guide which shaker you choose.

Mixers that benefit from shaking

Still, non-carbonated mixers blend and chill best when shaken with ice. These include:

Sour mix and margarita mix: citrus-and-sugar bases that turn bright and slightly frothy when shaken. Any of the three shaker types works well.
Fruit juices and purée-based mixers: shaking loosens thicker textures. A shaker with a separate strainer lets you double strain for a smoother finish.
Flavoured syrups: sugar syrups dissolve more evenly into cold liquid when shaken.
Cream-based or dairy-free creamy mixers: shaking builds a light, airy texture.

If you like drinks with a foamy top made from egg white or aquafaba (the liquid from a tin of chickpeas, used as a plant-based foaming agent), a tin-on-tin Boston shaker is the strongest choice because its tight seal and large space help build foam. These drinks are usually given a dry shake first, meaning a shake without ice to whip the foam, followed by a second shake with ice to chill.

Mixers you should not shake

Carbonated mixers such as tonic water, soda water, cola, lemonade and ginger beer should not be shaken in a sealed shaker. Shaking releases the bubbles, which can build pressure, push the lid off and leave you with a flat drink. Instead, shake the still ingredients, strain them into the glass, then top up with the fizzy mixer and stir gently once. This applies to every type of cocktail shaker.

Thick mixers that are better rolled

Thick, tomato-based mixers, such as a ready-made Bloody Mary mix, can turn foamy and thin if shaken hard. Many hosts roll them instead, which means pouring the drink gently back and forth between two vessels with ice. A Boston shaker makes rolling easy because its two open pieces can be used as the two vessels.

How to choose a cocktail shaker

The best cocktail shaker is the one that matches how often you host, how many people you serve and which mixers you use. Work through these steps:

Think about your usual gathering. For quiet evenings with one to four people, a cobbler shaker is simple and quick. For larger groups or regular parties, a Boston shaker handles bigger volumes and repeated use more easily.
Look at the mixers you buy most. If you mostly top spirits with tonic or soda, you may rarely need a shaker at all. If you use sour mix, juice, syrups or creamy mixers, a shaker becomes essential.
Decide whether you want a built-in strainer. Choose a cobbler shaker if you want everything in one piece. Choose a Boston or French shaker if you are happy to use a separate strainer, which also makes double straining easier.
Check the material. Stainless steel is durable, chills quickly and does not break. Glass parts let guests watch the drink but can crack. Plastic shakers are light and suit outdoor events, though they do not chill as quickly.
Check the capacity. Choose a shaker that holds the liquid for the number of drinks you usually make plus plenty of room for ice. Sizes vary between brands, so read the stated capacity before you buy.
Consider grip and cleaning. A shaker should feel comfortable to hold with both hands. Fewer small holes and crevices mean easier washing, especially after pulpy or creamy mixers.

How to shake a drink made with a ready-made mixer

Shaking a drink with a ready-made mixer takes only a few steps, and the method is similar for every type of cocktail shaker.

Chill your serving glass in the fridge or fill it with ice while you prepare the drink.
Pour the still ingredients into the shaker: your spirit or alcohol-free alternative, plus the ready-made mixer, following the measures on the mixer label.
Fill the shaker about two-thirds full with fresh ice.
Seal the shaker firmly. For a Boston shaker, press the smaller piece into the larger one at a slight angle. For a cobbler or French shaker, fit the lid and cap securely.
Shake hard, holding both ends, until the outside of the shaker feels very cold. Many bartenders aim for about 10 to 15 seconds.
Open the shaker. Tap a Boston shaker where the pieces meet; twist off the cap of a cobbler or French shaker.
Strain into the glass, using the built-in strainer or a separate strainer, and double strain if the mixer contains pulp.
If the recipe includes a fizzy mixer, add it now and stir gently once, then garnish and serve.

Glassware and serving suggestions

The right glass depends on whether the shaken drink is served with ice, without ice or topped with a fizzy mixer.

Coupe or martini-style glass: for drinks served up, meaning strained and served without ice, such as a sour made with ready-made sour mix.
Rocks glass: a short, heavy tumbler for shaken drinks poured over fresh ice, such as a margarita made from margarita mix.
Highball or Collins glass: tall glasses for drinks that are shaken and then topped with soda, tonic or ginger beer.

Simple garnishes such as a citrus wheel, a twist of peel or a few fresh herbs add aroma and make even a mixer-based drink feel special. For food, bright citrus drinks made with sour or margarita mix go well with salty snacks, grilled dishes and lightly spiced food, while creamy shaken drinks suit desserts and are best kept small.

Alcohol-free drinks made with a cocktail shaker

A cocktail shaker is just as useful for alcohol-free drinks, and having one means every guest can enjoy a properly made, chilled drink. Shaking gives non-alcoholic drinks the same cold, lively texture as cocktails.

Alcohol-free sour: shake a ready-made sour mix with an alcohol-free spirit alternative or a splash of fruit juice, plus aquafaba for a foamy top, and strain into a coupe.
Shaken fruit cooler: shake juice and a flavoured syrup with ice, strain into a tall glass over ice and top with soda water.
Virgin margarita-style drink: shake margarita mix with extra lime juice and a little orange juice, then serve in a rocks glass.

Offering a couple of shaken alcohol-free options alongside cocktails is an easy way to make a gathering feel welcoming and to help guests pace themselves.

Which shaker suits your next get-together?

For a relaxed dinner where you make a few drinks from ready-made mixers, a cobbler shaker gives you everything in one tool. For a lively party or a host who enjoys foamy sours and larger batches, a tin-on-tin Boston shaker with a Hawthorne strainer is the most versatile pairing. For a stylish, streamlined set-up, a French shaker with a separate strainer looks good and works well. Choose the shaker that fits the way you entertain, keep fizzy mixers out of it, and focus on serving fewer, well-made drinks that you and your guests will remember.
