Which Ice Cube Shapes Are Best for Your Restaurant

Table of Contents
Compare crescent cubes, nugget ice, flake ice, and more to find the right ice type for your beverages and operations
The shape of ice affects how quickly drinks cool, how fast ice melts, and how beverages taste. Crescent cubes offer superior liquid displacement and slow melting for mixed drinks. Nugget ice (also called Sonic ice or chewable ice) provides a soft, chewable texture popular with customers. Flake ice works best for food displays and seafood preservation. This guide covers each ice type, its ideal applications, and which ice machines produce each shape.
The ice in your drinks does more than keep beverages cold. Ice shape affects cooling speed, melt rate, flavor dilution, and even how full a glass looks. Choosing the right ice type for your operation can improve drink quality, reduce costs, and give customers a better experience.
Different ice shapes serve different purposes. Slow-melting cubes preserve the flavor of premium cocktails. Chewable nugget ice keeps customers coming back for refills. Flake ice protects delicate seafood in display cases. Understanding these differences helps you select ice machines that match your menu and service style.

Crescent Cubes

Crescent cubes are the workhorses of the foodservice industry. Their distinctive half-moon shape is instantly recognizable and delivers performance that standard square cubes cannot match.
The crescent shape was engineered for beverage service. When ice drops into a glass, crescent cubes naturally curve against the sides rather than stacking on top of each other. This creates exceptional liquid displacement, making drinks appear fuller with less liquid. For operators, this translates directly to cost savings on every pour.
Why Crescent Cubes Excel
Superior displacement: The curved shape allows more ice to fit in a glass while leaving room for liquid to flow around each piece. Drinks look generously filled, and customers perceive more value.
Reduced splashing: When liquid is poured over crescent cubes, the curved surface directs the flow smoothly into the glass. This prevents splashing that wastes product and creates cleanup.
Slow, even melting: Crescent cubes are solid and dense, melting slowly to keep drinks cold without rapid dilution. The consistent shape means predictable performance across every glass.
Versatility: From fountain sodas to premium cocktails to ice-cold water service, crescent cubes perform well across nearly every beverage application.
Crescent Cube Best Uses
- Soft drinks and fountain beverages
- Mixed drinks and cocktails
- Water service
- Iced tea and iced coffee
- Beer troughs and bottle service (keeps bottles cold for tableside presentation)
- General restaurant beverage service
Crescent cubes are the signature ice shape of Hoshizaki ice machines. Their KMEdge evaporator technology produces clear, hard crescent cubes using a double-sided freezing process that creates ice in fewer cycles than traditional grid-cell machines.
Nugget Ice (Sonic Ice / Chewable Ice)

Nugget ice has developed a devoted following. Also called Sonic ice, pebble ice, pellet ice, or chewable ice, this soft, airy ice type has customers seeking out restaurants specifically because of the ice they serve.
The appeal of nugget ice goes beyond just texture. Its porous structure absorbs the flavors of whatever drink it's in, making sodas taste sweeter and cocktails more intense. For operators, nugget ice also means happy customers who linger longer, order refills, and remember the experience. There's a reason people drive out of their way for "that ice."
The Origin of "Sonic Ice"
Scotsman Ice Systems invented nugget ice in 1981, originally designing it for healthcare facilities. Doctors needed an ice that patients with swallowing difficulties could safely chew without risking tooth damage. The soft, compressed texture solved this problem.
Sonic Drive-In began using Scotsman nugget ice machines in the mid-1980s for their signature slushes and drinks. Customers loved the chewable ice so much that "Sonic ice" became a household term. People started buying bags of ice from Sonic locations just to take home. Today, the demand for nugget ice at home has created an entire category of residential chewable ice makers.
How Nugget Ice Is Made
Nugget ice is created by compressing flake ice into small, cylindrical pieces. This process creates air pockets within each nugget, giving the ice its signature soft, chewable texture. The ice absorbs the flavors of beverages, which is why drinks served over nugget ice taste more flavorful to many customers.
Chewable Ice Terminology by Brand
Different manufacturers use different names for similar chewable ice:
| Brand: | Term Used: |
| Scotsman | Nugget Ice, "The Original Chewable Ice" (trademarked) |
| Hoshizaki | Cubelet |
| Ice-O-Matic | Pearl Ice |
| Manitowoc | Nugget Ice |
| Follett | Chewblet, Micro Chewblet |
Hoshizaki's Cubelet ice is produced using a similar compression method but results in a slightly denser, firmer texture compared to Scotsman's softer nugget. Both are considered chewable ice, and most customers cannot tell the difference.
Nugget Ice Best Uses
- Soft drinks and fountain beverages
- Iced coffee and cold brew (the soft texture complements coffee drinks)
- Smoothies and blended drinks
- Healthcare facilities (safe for patients to chew)
- Convenience stores and quick-service restaurants
- Any operation where customers enjoy chewing ice
Why Customers Love Nugget Ice
- Soft texture: Easy to chew without hurting teeth
- Flavor absorption: Soaks up drink flavors for a more intense taste
- Quick cooling: Cools beverages rapidly due to high surface area
- Fun factor: Many people simply enjoy crunching on soft ice
Full Cube Ice

Full cube ice, also called dice ice or square cube ice, is the standard ice shape found in most commercial settings. These solid, uniform cubes provide reliable cooling with minimal dilution.
The uniform shape of full cubes makes them ideal for operations that bag and sell ice or need consistent performance across high-volume service. Their solid construction means they stack neatly in bins, transport without breaking apart, and look professional in any glass. For many restaurants, full cubes are the dependable default that just works.
Full Cube Characteristics
- Size: Approximately 7/8" x 7/8" x 7/8"
- Melt rate: Slow
- Ice-to-water ratio: Nearly 100% (solid ice, minimal air)
- Appearance: Clear, uniform cubes
Full Cube Best Uses
- Ice bagging for retail sale
- Spirits served on the rocks
- Cocktails where slow dilution matters
- Self-service dispensing
- Catering and events
Full cubes are the most versatile ice shape for general commercial use. Their solid construction means they last longer in drinks and hold up well during transport and storage.
Half Cube Ice

Half cubes offer a balance between cooling speed and melt rate. Smaller than full cubes but still solid, half cubes pack tightly into glasses and dispensers.
The compact size of half cubes makes them a favorite for self-service beverage stations and fountain drink systems. They flow easily through dispensers without jamming, fill cups quickly during rush periods, and cool drinks faster than larger cubes. For high-volume operations where speed matters, half cubes deliver efficiency without sacrificing quality.
Half Cube Characteristics
- Size: Approximately 7/8" x 7/8" x 3/8"
- Melt rate: Moderate
- Also known as: Half dice, small cube
Half Cube Best Uses
- Fountain beverages
- Blended drinks and smoothies
- Self-service dispensing (fits dispensers well)
- Mixed drinks where moderate dilution is acceptable
- High-volume operations where ice consumption is heavy
Half cubes are popular in quick-service restaurants, convenience stores, and anywhere drinks are dispensed quickly. The smaller size means faster cooling, which customers appreciate when they want an immediately cold drink.
Flake Ice

Flake ice is soft, snow-like ice used primarily for food display and preservation rather than beverages. Its unique properties make it essential for specific applications.
Unlike cube ice, flake ice molds to the shape of whatever it surrounds, creating a protective blanket that keeps products cold from every angle. This conforming quality makes it irreplaceable for delicate items like sushi-grade fish, fresh oysters, and produce that would bruise under the weight of hard cubes. The visual appeal of a bed of pristine flake ice also signals freshness to customers at first glance.
Flake Ice Characteristics
- Texture: Soft, moldable, snow-like
- Ice-to-water ratio: Approximately 73% (contains air pockets)
- Melt rate: Quick
- Temperature: Colder than cube ice at the point of production
Why Flake Ice Melts Quickly
Unlike solid cube ice, flake ice contains significant air between the ice crystals. This lower density means faster melting. For beverage service, this would water down drinks too quickly. But for food display and preservation, the rapid cooling and moldable texture are exactly what operators need.
Flake Ice Best Uses
- Sushi cases and sushi displays: The standard ice for sushi restaurants, keeping fish at safe temperatures while providing an attractive bed for presentation
- Seafood displays: Keeps fish, shellfish, oysters, and other seafood fresh and visually appealing at raw bars and fish counters
- Produce displays: Maintains freshness in salad bars and produce sections
- Food prep and kitchen use: Bakers use flake ice to keep dough cold, and kitchens use ice baths for blanching vegetables and chilling soups
- Meat packing: Protects meat during transport and storage
- Medical applications: Cold compresses that mold to the body without excessive pressure
- Blended drinks: Creates smooth texture in frozen margaritas, daiquiris, and smoothies
Flake ice is essential equipment for sushi restaurants, bakeries, grocery stores, fish markets, buffets, and healthcare facilities. Restaurants with raw bars, oyster bars, or seafood displays rely on flake ice to keep product fresh and safe throughout service.
Gourmet Ice (Top Hat Ice)

Gourmet ice, also called top hat ice or octagon ice, is designed for upscale beverage service. Crystal-clear and elegantly shaped, these cubes elevate the presentation of premium drinks.
The crystal clarity of gourmet ice comes from a specialized freezing process that eliminates the cloudy center found in standard cubes. When a customer orders a $15 cocktail or a pour of aged whiskey, the ice should match the quality of what's in the glass. Gourmet ice makes that statement without saying a word, signaling attention to detail that justifies premium pricing.
Gourmet Ice Characteristics
- Size: Approximately 1 3/8" x 1 3/8" (cylindrical or octagonal)
- Melt rate: Slow
- Appearance: Crystal clear, no cloudiness
- Ice-to-water ratio: Nearly 100%
What Makes Gourmet Ice Different
Gourmet ice is frozen from the outside in, pushing air and impurities to the center where they are flushed away. This process creates perfectly clear ice without the cloudy center found in standard cubes. The result is ice that looks as premium as the spirits it accompanies.
Gourmet Ice Best Uses
- Premium whiskeys and bourbons
- High-end cocktails (Old Fashioneds, Manhattans)
- Upscale bar and lounge service
- Banquet and event catering
- Executive suites and VIP areas
Gourmet ice is typically found only in undercounter machines, limiting its availability to bars and beverage stations rather than high-volume production. The slower production rate is offset by the premium presentation value.
Square Cube Ice

Square cube ice represents the newest innovation in commercial ice production. These large, perfectly square cubes are designed specifically for craft cocktails and premium spirits.
The oversized dimensions of square cubes mean dramatically slower melting, which keeps drinks stronger for longer. Bartenders at craft cocktail establishments favor this ice because it gives guests time to savor their drink without rushing before dilution takes over. The bold, geometric look of a large square cube in an Old Fashioned glass has become a signature of serious cocktail programs.
Square Cube Characteristics
- Size: Approximately 1 1/4" x 1 1/4" x 1 1/4"
- Melt rate: Slowest of all cube types
- Appearance: Large, clear, uniform squares
Square Cube Best Uses
- Craft cocktail bars
- Whiskey and bourbon service
- Premium spirits on the rocks
- High-end restaurant bars
- Establishments focused on cocktail presentation
Hoshizaki's square cube ice machines (like the IM-500SAB) produce these large, impressive cubes that have become standard in craft cocktail programs. The extra-slow melt rate means drinks stay strong longer, and the visual impact of a large, clear cube adds perceived value to every pour.

Frequently Asked Questions
What is Sonic ice?
Sonic ice is a popular term for nugget ice, named after the Sonic Drive-In restaurant chain. Sonic began using Scotsman nugget ice machines in the mid-1980s, and customers loved the soft, chewable texture so much that "Sonic ice" became a common name for this ice type. Scotsman invented nugget ice in 1981 and holds the trademark for "The Original Chewable Ice."
What is the difference between nugget ice and cubelet ice?
Nugget ice and cubelet ice are both chewable ice types made by compressing flake ice. The main difference is the manufacturer: Scotsman calls theirs nugget ice, while Hoshizaki uses the term cubelet. Hoshizaki's cubelet tends to be slightly denser and firmer than Scotsman's softer nugget ice, but both serve the same purpose and most customers consider them interchangeable.
Which ice type melts the slowest?
Square cubes and gourmet (top hat) ice melt the slowest due to their large size and solid construction. Among standard ice types, crescent cubes and full cubes also melt slowly. Nugget ice and flake ice melt the fastest because they contain more air and have greater surface area.
Why do restaurants use crescent ice?
Crescent ice offers superior liquid displacement, making drinks look fuller with less liquid. The curved shape prevents splashing when drinks are poured, reduces waste, and melts slowly to maintain drink flavor. Crescent cubes are also versatile enough to work well across nearly every beverage type, from sodas to cocktails to water service.
Can I get Sonic ice for my home?
Yes. Several manufacturers now make residential nugget ice machines. Scotsman offers the Brilliance series for home use, which produces the same nugget ice they invented for commercial use. Other brands like GE and Frigidaire also make countertop nugget ice makers for residential kitchens.
What ice is best for whiskey?
Large, slow-melting ice is best for whiskey. Gourmet (top hat) ice and square cubes are the top choices because they chill the spirit without rapid dilution. Some whiskey bars use oversized ice spheres or large cubes specifically to minimize water added to the drink while still achieving proper temperature.
What is the best ice for smoothies?
Nugget ice or flake ice works best for smoothies. Both blend easily and create smooth texture without damaging blender blades. Flake ice incorporates quickly, while nugget ice adds a slight chewable texture that some customers prefer. Avoid using large, hard cubes which can strain blenders and create uneven texture.
Why is my ice cloudy?
Cloudy ice forms when air and minerals get trapped during freezing. Standard ice machines freeze water from the outside in, trapping impurities in the center. Gourmet ice machines freeze water directionally and flush away impurities, creating crystal-clear ice. Water quality also affects clarity; using filtered water produces clearer ice regardless of machine type.
What type of ice do sushi restaurants use?
Sushi restaurants use flake ice in their sushi cases and display areas. Flake ice is soft and moldable, allowing it to cradle delicate fish while maintaining safe temperatures. The snow-like texture creates an attractive presentation and keeps sushi-grade fish fresh throughout service. Flake ice is the industry standard for sushi displays, raw bars, and any seafood presentation.
What ice is best for iced coffee and cold brew?
Nugget ice and crescent cubes are both popular choices for iced coffee. Nugget ice cools drinks quickly and has a soft texture that coffee shop customers love. Crescent cubes melt more slowly, which prevents over-dilution of cold brew and iced lattes. Many specialty coffee shops choose nugget ice for the same reason Sonic made it famous: customers enjoy the chewable texture between sips.
