Types of Cocktail Ice 

Standard cubes are the workhorses behind the bar. Roughly one-inch cubes are excellent all-purpose ice for shaking, stirring, highballs, and cocktails served on the rocks.

If you could have only one type of cocktail ice, this would be it.

They're not flashy.

Neither is a good pair of black work shoes, but bartenders appreciate both.

​

Large Cubes

Large cubes—often around two inches—are commonly used for spirit-forward cocktails such as an Old Fashioned or Negroni.

One large cube has less surface area relative to its volume than a bunch of smaller cubes, so it generally melts more slowly and keeps a drink cold without becoming watery as quickly.

And let's admit it: a giant crystal-clear cube makes almost any cocktail look $5 more expensive.

​

Crushed Ice

Crushed ice consists of small irregular pieces and is ideal for drinks such as Mint Juleps, Swizzles, and many tropical cocktails.

You can buy an ice crusher or go old school with a Lewis bag: put ice into the heavy canvas bag and whack it with a wooden mallet until crushed. —SHOP

It's cocktail preparation and stress management in one convenient activity.

​

Pebble / Pellet / Nugget Ice

Call it pebble ice, pellet ice, nugget ice, or—as many Americans inevitably do—Sonic ice. —SHOP

It's made of small, soft, chewable pieces and works beautifully in tropical cocktails, swizzles, cobblers, and other drinks designed around lots of cold, crunchy ice.

Because the pieces have lots of surface area, they dilute drinks faster than large cubes. That isn't necessarily bad—the cocktail should be designed with that dilution in mind.

I've bought hundreds of bags of Sonic ice over the years.

At some point that probably qualifies as a relationship.

​

Shaved Ice

Shaved ice is made by shaving a block of ice into extremely fine, fluffy crystals.

New Orleans knows all about this. The city's famous sno-balls use finely shaved ice that absorbs flavored syrup rather than allowing most of it to sink straight to the bottom.

For cocktails, shaved ice can create dramatic frozen presentations and chill drinks extremely quickly.

​

Ice Spheres

Hand-carved ice spheres became especially associated with the precision and presentation of Japanese bartending.

A sphere has the lowest surface-area-to-volume ratio of any shape, although in practical cocktail terms the dilution difference between a large sphere and similarly sized large cube isn't enormous.

So why use one?

Because it looks fabulous.

Today you don't need five minutes, an ice pick, and Japanese bartending skills. Silicone sphere molds and clear-ice sphere makers are widely available for home use.

​

Collins Spears

A Collins spear is a long rectangular piece of ice designed to fit neatly into a Collins or highball glass.

Besides looking beautiful, one large spear provides less exposed surface area than filling the glass with many small cubes, helping control dilution. It also leaves plenty of room for carbonated mixers.

It's basically the cocktail equivalent of custom tailoring.

​

You can also use these in Stanley cups. —SHOP
 

​Block Ice

And this is where we started.

Modern cocktail bars sometimes purchase or make large blocks of clear ice, then hand-cut them into cubes, spears, chunks, and other shapes.

Watching a skilled bartender break down a gorgeous clear block of ice with picks and saws is fascinating.

Watching an unskilled person attempt it is why we have emergency rooms.

​

​

Clear Ice

Clear ice became one of the signatures of the modern craft-cocktail movement. It looks beautiful in a glass—but contrary to a lot of old cocktail advice, you do not need distilled water or repeatedly boiled water to make it.

​

Cloudy household ice forms because water in an ordinary tray freezes from several directions, trapping dissolved gases and other material toward the center.

The breakthrough came in 2009, when cocktail writer Camper English documented what became known as directional freezing. Instead of trying to purify the water into submission, you control the direction in which it freezes.

​

Directional Freezing at Home

The classic method is surprisingly simple:

Fill a small hard-sided insulated cooler with water.

Leave the lid off.

Place it in the freezer.

Because the cooler insulates the sides and bottom, the water primarily freezes from the top downward. Air and impurities are pushed toward the last portion to freeze, leaving most of the upper block beautifully clear.

Remove the block before it freezes completely, or cut away the cloudy bottom afterward.
 

Today you can also buy clear-ice molds that essentially perform directional freezing for you. —SHOP

​

Homemade Cocktail Ice

You don't need a $20,000 bar ice program to have fun with ice.

Silicone molds now come in just about every imaginable size and shape: cubes, spheres, diamonds, skulls, flowers, hearts, stars, golf balls, and probably something shaped like Nicolas Cage if you search long enough.

For cocktails, larger shapes generally work better because tiny decorative ice melts quickly.

You can also freeze ingredients into your ice:

Citrus slices • berries • herbs • edible flowers • cucumber • mint • coffee • coconut water • fruit juice • ginger beer

Just remember: whatever you freeze into cocktail ice should be food-safe and something you'd be comfortable putting directly into someone's drink.

​

Punch Ice

For a punch bowl, one large block of ice is usually better than dozens of little cubes because it melts more slowly.

​

Here's an old inexpensive trick: wash an empty paper milk or juice carton, fill it with water, and freeze it. When you're ready for the party, tear away the carton and place the giant block into your punch bowl.

Even better, freeze some of the punch's nonalcoholic ingredients instead of water. As the block melts, you're adding flavor instead of simply watering down the punch.

​

You can also freeze citrus slices, berries, herbs, or edible flowers inside the block.

Suddenly your old milk carton has a craft-cocktail ice program.

​

Ice Around a Bottle

Place a bottle inside a clean paper carton or other freezer-safe container. Add enough water to surround most of the bottle and freeze it. Once frozen, remove the outer container and you'll have a bottle encased in ice.

Add citrus wheels, berries, herbs, or edible flowers during freezing for decoration.

Just remember that water expands when frozen, so don't completely trap or submerge a bottle in a way that could cause breakage.

​

The Glass Is Half Full

In 2014, I came up with what I call my “Glass Is Half Full” technique.

I didn't want to spend money on fancy molds, so I filled Old-Fashioned glasses halfway with

water, covered them, and froze the glasses. When I needed one, I removed it from the freezer

and strained the finished cocktail directly over the ice frozen inside the glass.

​

Then I took it one step further and served the glasses on lighted coasters.

Was it necessary?

Absolutely not.

Did it look cool? Absolutely.

Dry Ice & Cocktails

Dry ice is frozen carbon dioxide (CO₂) that bartenders use to create dramatic bubbling, fog, and smoke-like effects around cocktails. Unlike regular ice, dry ice doesn't melt into water—it sublimates, changing directly from a solid into carbon dioxide gas. At about −109°F (−79°C), it's cold enough to cause serious frostbite, so never handle it with bare hands or swallow it. Use insulated gloves or appropriate tongs when handling it.

You will need to contact local ice companies to find it.
 

You can use dry ice around a cocktail for presentation—such as beneath a glass, in a separate compartment of a serving vessel, or in a punch-bowl display where guests cannot reach it. 
This happens often around Halloween to create drama on the bar top.

 

Bartenders can also use specially designed dry-ice stir sticks that hold a small pellet inside a perforated safety cage. Once placed in the drink, the liquid activates the dry ice and creates the bubbling fog while the solid pellet remains trapped inside the device. —SHOP

​

Safety is an important part. Never serve loose pieces of dry ice where a guest could accidentally swallow or touch them. If you place dry ice directly into a beverage, FDA guidance is to ensure it has completely sublimated before the beverage is consumed. Dry ice also releases carbon dioxide gas, so use and store it in a well-ventilated area, and never keep it in an airtight container—accumulating gas can create dangerous pressure.
 

Good to know: That mysterious white “smoke” isn't actually smoke. The extremely cold CO₂ chills the surrounding air, creating a visible fog of tiny condensed water droplets. And because the CO₂ disappears into gas instead of melting into water, dry ice doesn't dilute a cocktail the way ordinary ice does.

​

Dry ice can turn a cocktail into a showstopper. Just remember: the drama belongs in the glass—not in the emergency room.
