High temperature cheese is a specialty cheese designed to hold its shape at cooking temperatures that would turn regular cheese into a puddle. It has a melting point around 400°F, compared to standard cheeses that start melting between 130°F and 180°F. It’s most commonly used in sausage making, where cheese cubes need to survive a smoker or grill without liquefying and leaking out of the casing.
How It’s Made Differently
The key difference happens during the curdling process. When making regular cheddar or similar soft cheeses, the milk is cooled before curds form. That cooling step produces a soft, smooth, slightly crumbly texture that melts predictably when heated.
High temperature cheese takes the opposite approach. The milk is heated during curdling, which causes the curd particles to deform and close together more tightly, trapping less moisture inside. The result is a cheese that’s tougher, denser, and drier than its conventional counterpart. If you’ve ever pulled apart a stick of string cheese, you have a good sense of the consistency. It’s firm and somewhat rubbery at room temperature, and when cooked it softens and gets creamy without losing its structure.
There’s no official FDA standard defining “high temperature cheese” as a product category. It’s an industry term used by cheese and sausage-making suppliers rather than a regulated classification.
Available Varieties
Most popular cheese styles come in a high-temp version. The staples are cheddar, mozzarella, and Swiss. For bolder flavors, you can find pepper jack, habanero, and blue cheese versions. They’re typically sold as small cubes or diced pieces, pre-cut to a size that mixes easily into ground meat or sausage.
Why Sausage Makers Rely on It
Sausage making is by far the most common use. When you smoke a sausage at 170°F to 200°F, regular cheese would melt completely, pooling at the bottom of the casing or leaking out through any weak spot. High-temp cheese cubes stay intact at those temperatures. They soften just enough to give each bite a creamy, rich pocket of flavor without compromising the sausage’s structure.
Cheddar and jalapeño is a classic combination for a Mexican-inspired sausage. Swiss adds a tart, nutty note to links finished at higher cooking temperatures. Some producers even make specialty items like Hawaiian pizza bratwurst, which wouldn’t hold together with conventional cheese inside.
Uses Beyond Sausage
High-temp cheese works well anywhere you want cheese to be present without disappearing into the dish. Mixed into ground beef for burgers, the cubes hold their shape on a hot grill, creating distinct pockets of melted cheese throughout the patty rather than a greasy layer that drips into the flames. The same principle works for tacos or meatballs.
You can also place high-temp cheese directly on grill grates. It picks up char marks and softens without collapsing, making it a useful addition to salads, pasta, or charcuterie boards. Grilled or smoked cheese cubes offer a flavor and texture you can’t replicate with regular cheese.
Taste and Texture Differences
Uncooked, high-temp cheese tastes like the variety it’s based on, but the texture is noticeably different. It’s firmer and chewier, with less of the creamy mouthfeel you’d expect from a standard block of cheddar or jack. Some people find it slightly bland compared to aged versions of the same cheese, since the denser structure can mute some of the sharper flavor notes.
Once heated, the difference narrows. The cheese softens and becomes creamy, delivering a flavor burst that’s close to the original variety. In a sausage or burger, most people can’t distinguish high-temp cheddar from regular cheddar by taste alone. The texture difference is the whole point: you get cheese flavor distributed throughout the product rather than lost to the cooking process.
Storage and Shelf Life
High-temp cheese follows the same storage rules as the cheese variety it’s based on. Hard and semi-hard cheeses like cheddar and Swiss last up to six months unopened in the refrigerator and three to four weeks once opened. They can also be frozen for up to six months without significant quality loss, which is convenient if you buy in bulk for occasional sausage-making sessions.
Because high-temp cheese is drier than standard cheese, it’s slightly more forgiving in the fridge. It dries out less quickly at the cut surfaces and is less prone to developing the slimy texture that softer cheeses get when they start to turn. Vacuum-sealed packages, which most suppliers use, extend shelf life further and make freezing straightforward.
Where to Buy It
You won’t typically find high-temp cheese at a regular grocery store. It’s a specialty product sold primarily through sausage-making supply companies, butcher shops, and online retailers that cater to home meat processing. It’s usually sold in one-pound or five-pound bags of pre-diced cubes. Prices run slightly higher than standard cheese of the same variety, reflecting the smaller market and specialty production process.
