Over 5,500 different types of cheese exist globally, with many prized for their ability to improve with age. But why does aging cheese make it better? The process, also known as affinage, involves a controlled breakdown of proteins and fats by enzymes and microbes, which transforms a simple curd into a complex culinary masterpiece.

The USDA specifies that low-moisture mozzarella cheese has a pH not less than 5.1 and not more than 5.4, while fresh mozzarella typically falls between 5.5 and 5.7. These ranges indicate that mozzarella is, in fact, a mildly acidic food, with its exact level of acidity dependent on its type and production method. This mildness is key to its popular, delicate flavor profile and unique melt characteristics.

Over 55% of American households consume feta cheese regularly, but for those opting for a healthier version, the question arises: can you melt fat-free feta? The short answer is no, not in the traditional, gooey way you'd expect from cheeses like mozzarella. It lacks the necessary fat content and has a different protein structure that prevents it from truly melting.

According to cheese experts at Classpop!, Colby Jack melts into a smooth and creamy consistency without becoming stringy. Despite being a popular choice for melting, many people wonder, "Is Colby Jack cheese stringy?", especially when comparing it to other popular melting cheeses like mozzarella. The answer lies in its unique production method and curd makeup, which result in a high-moisture cheese that flows rather than stretches.

The world record for the longest cheese pull was set in 2023 at 15 meters using a blend of mozzarella and cheddar, proving that stretchy cheese is a universal crowd-pleaser. So, what kind of cheese is stretchy and why does it melt so magnificently into long, gooey strands? The answer lies in the cheese's internal protein structure, which is engineered for optimal stretch and melt.

While the microwave is a fast and convenient appliance, many home cooks have experienced the unfortunate result of a microwaved cheese disaster. The answer to "is it okay to microwave cheese?" is yes, but achieving that perfect, gooey melt requires a specific, low-and-slow approach to avoid a disappointing, separated texture.

Many popular cheeses, like sharp cheddar, have a naturally low pH below 5.2 due to lactic acid fermentation. If you are looking for milder, high-pH options, the least acidic cheeses include delicate varieties such as ricotta, Brie, and blue cheese, which are processed to retain more calcium and balance their final acidity levels.

Did you know that aged cheeses, like Parmesan and Cheddar, are naturally lower in lactose because beneficial bacteria consume the sugar during the aging process? Understanding which enzyme digests cheese reveals how our bodies break down this dairy product's proteins, fats, and residual sugars.

Excessive oiling-off, where a melted cheese like mozzarella becomes visibly oily, is a recognized quality defect in the dairy industry, though it's a common observation for home cooks. This phenomenon, often seen on pizzas and other baked goods, is a result of the cheese's fat content separating from its protein structure when heated.

According to nutritional data, many popular cheeses contain over 20g of fat per 100g, classifying them as high-fat foods. Understanding which cheeses are oily is key to cooking successfully, as high fat content and melting properties determine if cheese will release a pool of grease or create a smooth, creamy sauce.
