One is pleasant to chew and melts fast. The other barely waters your drink down. The decision is about what you drink, not which machine is better.
Updated October 2026 · By Stephen V.
Buy nugget if you drink sodas, iced coffee and long mixed drinks; buy clear cube if you drink spirits over ice. The GE Profile Opal Ultra is the nugget pick and the Newair countertop clear ice maker the cube pick. This is a question about your glass, not about machine quality — both are good machines and they make genuinely different products.
The underlying difference is physical. Nugget ice is compacted flake — snow, essentially — so it is soft, full of air, chewable, and has an enormous surface area for its weight. Clear cube ice is slow-frozen in layers so impurities and air are pushed out, leaving dense transparent ice with very little surface area. Every practical difference below follows from those two sentences.
The short answer
In a hurry? These are the picks we'd buy. Prices are live; tap a card below for the full reasoning.
Dense, transparent, slow-melting cubes that barely dilute a drink over twenty minutes — and the only ice here that looks good in a glass.
Ice
Clear cube
First batch
Under 15 minutes per listing
Melt rate
Slowest
Dilution
Low
Noise
Compressor hum, periodic drop
Pros
Melts slowly, so a sipped drink stays a drink rather than becoming water
Clear ice looks dramatically better in a glass than cloudy or nugget
Simpler mechanism than a nugget machine — less to scale up and fail
More versatile: works in a cooler, a highball or a tumbler
Cons
Hard cubes, not chewable
Slower per pound than bullet-ice machines, because clear freezing takes time
Does not absorb a drink's flavour — which some people specifically want
Best for: Whisky, old fashioneds, negronis, and anything you sip slowly.
How to choose (and what to skip)
Decide from your most common drink
Pour what you usually drink and ask whether you want the ice to disappear into it or stay out of the way. Soda, iced coffee, iced tea, a tall mixed drink finished in fifteen minutes: nugget, because the ice becomes part of the drink and chewing it is half the pleasure. A whisky, an old fashioned, a negroni, anything sipped over twenty minutes: clear cube, because dilution is the enemy.
Count the household
Nugget ice is the only type children reliably like, and it is safe to chew in a way a hard cube is not. If the machine is for a family kitchen as much as a bar, that tips it decisively toward nugget regardless of what the adults drink.
Weigh maintenance honestly
Nugget machines use an auger and a compression head and keep more water moving through more parts, so scale has more places to build and descaling matters more. Cube machines are mechanically simpler. If you know you are not going to keep up with a cleaning schedule, cube is the more forgiving choice — and either way, filtered water roughly halves the problem.
Think about noise and where it will live
A nugget machine grinds more or less continuously while producing — it is the noisiest countertop appliance in a bar. A cube machine hums and then clatters periodically as a batch drops. If the machine is going in an open-plan room where people watch television, that difference is worth more than it looks on paper.
Consider having both, cheaply
You do not need two machines to get both. A nugget machine plus a clear-ice cube tray — a silicone insulated tray that freezes directionally in your own freezer for a few dollars — covers both needs. The tray makes a handful of large clear cubes or spheres slowly, which is exactly the quantity a spirits drinker needs, while the machine handles volume.
Why clear ice dilutes less
Melting is a surface phenomenon: ice melts where it touches liquid. A single dense 2-inch cube has a small surface area relative to its mass, so it cools the drink and then sits there. A glass packed with nugget ice has an enormous combined surface area, so it cools the drink very quickly and then keeps melting into it. Within fifteen minutes the nugget glass is noticeably weaker.
Both behaviours are useful. Fast cooling and some dilution is exactly right for a spirit-forward long drink that you want cold and drinkable immediately. Slow cooling and minimal dilution is exactly right for whisky you want to taste at the end of the glass the way it tasted at the start. The mistake is expecting one ice type to do both jobs.
Bullet ice: the third option nobody asks for
Most sub-$100 countertop machines make neither nugget nor clear cube. They make bullet ice: hollow, cloudy cylinders, ready in six to ten minutes. The hollow centre means it melts quickly and the cloudiness means it looks cheap, but these machines produce a lot of ice for very little money and are genuinely the right answer for filling a cooler, serving a crowd, or a first bar where ice volume matters more than ice quality.
If your honest requirement is "a lot of cold ice, cheaply", do not pay nugget or clear-ice prices. Buy a bullet machine and spend the difference on something else in the bar.
What neither machine will do
Neither will store ice. Countertop machines of both types drop ice into an insulated but unrefrigerated basket, so it melts back into the reservoir and gets re-frozen. Nugget melts back faster because it is softer, but the limitation applies to both. If you want ice waiting for you rather than being made, you need an undercounter machine with a cooled bin, or the simple habit of bagging early batches into your freezer.
And neither will make ice that tastes better than the water you put in. Filtered water improves both, and keeping ice covered in the freezer stops it absorbing smells — which is the actual reason freezer ice has a bad reputation. Our nugget ice guide goes further into whether the premium is justified.
Frequently asked questions
Which is better, nugget or cube ice?+
Neither — they suit different drinks. Nugget is soft, chewable and absorbs the drink, which makes it right for sodas, iced coffee and long mixed drinks. Clear cube is dense and slow-melting, which makes it right for spirits you sip. Choose from what you usually drink rather than from which machine seems better.
Does nugget ice water down a drink more than cube ice?+
Yes, noticeably. Nugget ice is compacted flake with a very large surface area for its weight, so it cools fast and keeps melting. A dense clear cube has far less surface area and barely dilutes over twenty minutes. For a whisky that difference is the whole argument for cube ice.
Are nugget ice makers less reliable than cube machines?+
They have more to go wrong. A nugget machine needs an auger and a compression head and keeps more water circulating, so mineral scale has more places to accumulate and descaling matters more. A cube machine is mechanically simpler. Either lasts well if you descale on schedule and use filtered water.
Can I get clear ice without buying a clear ice machine?+
Yes. An insulated directional-freezing tray in your own freezer makes a handful of large clear cubes or spheres for a few dollars — slowly, but that is the quantity a spirits drinker needs. Pairing one of those with a cheaper high-volume machine is often better value than buying a dedicated clear-ice machine.
