Why Is Sonic Ice So Good?
It is not the water. It is the shape. Sonic uses nugget ice, which is made from compressed flakes full of tiny air pockets, so it is soft to chew and soaks up the drink around it.
People who say Sonic ice tastes better are not imagining it. By the bottom of the cup, the ice has absorbed some of the drink, which is why the leftover ice is often the best part.
How nugget ice is made
A normal ice machine freezes water in a mold until it forms a hard, clear cube. A nugget ice machine works in a completely different way.
| Step | What happens |
|---|---|
| 1. Flakes form | Water freezes in a thin layer on the inside of a chilled metal cylinder. |
| 2. Scraping | A rotating auger scrapes the flakes off the cylinder wall as they form. |
| 3. Compressing | The auger pushes the flakes up through a narrow opening, packing them together. |
| 4. Cutting | The packed ice comes out as a column and breaks into small nuggets about the size of a fingertip. |
Because the nuggets are pressed flakes rather than frozen solid, they keep small pockets of air and water inside. That structure is what gives Sonic ice its texture.
Why it tastes better
| What people notice | Why it happens |
|---|---|
| It is soft to chew | The nuggets are packed flakes with air inside, so they crumble instead of cracking like a hard cube. |
| It soaks up flavor | The air and water pockets absorb the drink, so the ice tastes of soda, tea or limeade. |
| Drinks get cold fast | Lots of small pieces have more surface touching the drink than a few big cubes. |
| Very sweet drinks taste lighter | The ice dilutes a drink a little as it melts, which balances sugary flavors. |
Where it came from
Nugget ice was pioneered by Scotsman, an American ice machine maker, which introduced its first chewable nugget ice machine, the MH750, in 1981. Sonic began putting Scotsman nugget ice machines in its drive ins in the mid 1980s, and the ice became part of the brand without the company ever needing to advertise it.
It was a good fit for a drink led chain. Sonic sells a huge range of sodas, slushes, limeades and flavored drinks, many of them in very large cups, and ice that cools fast and soaks up flavor suits that menu. The Route 44 and the rest of the drink sizes are listed on the Sonic menu.
Nugget ice machines are also cheaper to run in one important way. Scotsman says they use about 40 percent less water and 15 percent less energy than traditional cube machines.
Can you buy Sonic ice?
Yes, at many locations. Sonic drive ins commonly sell bags of ice, usually 10 pounds, for around 3 dollars, and you can also order a cup of ice on its own. Price and availability are set by each drive in, so it is worth calling ahead, especially in summer when bags can sell out.
One thing to know is that slushes do not use nugget ice. They are made with a different frozen process, so if you are after the chewable ice, order a fountain drink instead.
Other places that use it
Sonic made nugget ice famous, but it is not the only chain that uses it. Chick-fil-A also serves nugget ice and sells bags of it at many restaurants, and countertop nugget ice makers for the home have become popular, usually costing a few hundred dollars.
Sonic’s name and history have nothing to do with the ice. That story, which starts with a drive in called Top Hat, is in why is it called Sonic.
