How to Make Clear Ice: The Complete Guide to Commercial Ice Makers for Bars
Over the past decade, large clear ice cubes have become the standard at better cocktail bars across America. They can come in two-inch cubes or rectangular “spears” for Collins glasses, or be carved or pressed into spheres and other shapes. They look fantastic compared with cloudy cubes, make even the simplest cocktails look mixology-fancy, and often earn the free advertising that comes from visitors sharing Instagram pics of the drinks at your bar.
But achieving that level of clarity and size consistently—day after day, during peak service hours—requires more than manual effort. It demands the right equipment: a commercial ice maker designed specifically for clear ice production.
In this comprehensive guide, we’ll explore the science behind clear ice, compare manual methods with professional solutions, and help you choose the perfect high-capacity commercial ice maker for your bar, restaurant, or bubble tea shop. Whether you need a clear ice commercial ice maker for craft cocktails or a nugget ice commercial ice maker for refreshing beverages, we’ll cover everything you need to know.

The Science of Clear Ice: Why It's Different
Understanding why ice becomes cloudy is the first step to making it clear. When water freezes into ice, the forming ice crystal lattice rejects air and any impurities in the water. In a typical ice cube tray, water freezes from all sides toward the middle. The air and impurities are pushed into the center, eventually forming that familiar cloudy core. Expansion of the ice during freezing causes cracks that magnify the cloudy appearance.
Clear ice requires controlling the freezing direction. When water is forced to freeze from one direction only—typically from the top down—impurities are pushed ahead of the freezing front, eventually collecting at the bottom. The result: a completely transparent block of ice above, with any cloudiness confined to the very bottom where it can be removed.
This principle is what professional clear ice commercial ice makers leverage to produce beautiful, consistent cubes for the world’s best cocktail bars.
A Small Clear Ice Program: Manual Methods for Startups
For very small operations or as a temporary measure, clear ice can be made manually using a technique called “directional freezing.” This involves filling an insulated cooler with water and placing it in a freezer with the lid off. Because the sides and bottom are insulated, the water freezes from the top down, pushing impurities to the bottom.
When only the last third or so of the water starts freezing does the ice become cloudy in that section, as trapped air has nowhere else to go. To harvest only clear ice, you remove the cooler before the cloudy part forms, or freeze the entire block and cut away the cloudy bottom.
The limitations of manual methods:
Requires significant freezer space
Labor-intensive cutting and processing
Inconsistent results
Not scalable for high-volume operations
Takes 24-48 hours per batch
While manual methods can work for a tiny bar testing the waters, any serious operation needs a commercial ice machine designed for consistent, high-quality production.
Professional Clear Ice: Commercial Ice Makers for High-Volume Bars
When your bar’s reputation—and your customers’ Instagram posts—depend on consistently beautiful ice, it’s time to invest in professional equipment.

Not every drink calls for clear cube ice. Perhaps your menu includes frozen cocktails that benefit from nugget ice, or you need flake ice for seafood displays. Naixer’s multi-type commercial ice maker lineup gives you the flexibility to produce exactly what your business needs.
Nugget ice—that soft, chewable ice made famous by quick-service chains—has become incredibly popular in bubble tea shops, cafes, and casual dining venues. Unlike hard cubes, nugget ice absorbs the flavor of the drink, creating a delightful treat at the bottom of the cup.

Commercial Ice Maker Buying Guide: Making the Right Investment
Choosing the right commercial ice maker involves more than picking a model you like. Here’s a systematic approach to ensure you get the perfect fit for your business.
Commercial Ice Maker Capacity Calculation
The most common mistake is undersizing. Use this formula:Daily ice needed = (Peak hour customers × ice per drink × peak hours) + (kitchen/bar prep needs) + 20% buffer
Example:
50 customers per peak hour × 2 drinks each × 0.5 lb ice per drink = 50 lbs per hour
4 peak hours = 200 lbs daily
Plus 50 lbs for prep = 250 lbs
Plus 20% buffer = 300 lbs daily requirement
Reference Naixer capacities:
ZD-160 dispenser system: 160 kg (350 lbs) daily
TH500B: 225 kg (495 lbs) daily
TH700B: 320 kg (705 lbs) daily
Commercial Ice Maker Cost Considerations
Commercial ice maker cost involves more than the purchase price. Consider:
Initial investment: $2,000-$10,000+ depending on size and features
Energy consumption: Look for energy-efficient models to reduce commercial ice maker electricity consumption
Water usage: Especially important for water-cooled models
Maintenance costs: Factor in filter replacements, professional cleaning
Lifespan: Quality machines last 7-10 years with proper care
Commercial Ice Maker Space Requirements
Before purchasing, measure your space carefully:
Footprint: Width, depth, height of the unit
Ventilation clearance: Air-cooled models need space behind and sides (usually 4-6 inches)
Access: Can you get the machine into your space?
Utilities: Proximity to water line, drain, and electrical outlet
Commercial Ice Maker Maintenance Schedule
To keep your NSF certified commercial ice maker performing optimally:
Daily: Wipe exterior, check for unusual sounds
Weekly: Sanitize ice storage bin, inspect air filters
Monthly: Deep clean interior surfaces, clean condenser coils
Quarterly: Professional descaling and sanitization
Annually: Comprehensive professional inspection
