A guide to the three faces of mozzarella — fresh, low-moisture, and buffalo — including how each is made and when to use them.
Mozzarella is one of the most-eaten cheeses on earth, yet the soft white ball sitting in brine at an Italian deli and the shreds melting on a takeout pizza are barely the same product. Understanding the mozzarella family — fresh, low-moisture, and buffalo — helps you buy the right one for caprese, pizza, or a quick snack.
What Makes Mozzarella Different
Mozzarella belongs to a family called pasta filata, or "spun paste." After the curd forms, it's heated and stretched until it becomes smooth, glossy, and elastic, then shaped into balls or blocks. This stretching is what gives mozzarella its signature pull and stringiness when melted. Unlike aged cheeses, classic mozzarella is meant to be eaten within days of being made.
Fresh Mozzarella
Fresh mozzarella (fior di latte when made from cow's milk) is the soft, milky ball sold floating in water or whey. It has a delicate, sweet, lactic flavor and a tender, almost springy texture. Because it holds a lot of moisture, it's best eaten raw or barely warmed — sliced into a caprese salad with tomatoes and basil, torn over a finished pizza, or served simply with good olive oil and salt. Its high water content means it can make a pizza soggy if used straight from the tub without draining.
Low-Moisture Mozzarella
Low-moisture mozzarella is the firmer, drier, longer-lasting version most people know from pizza. By removing more whey and aging the cheese briefly, makers create a product that shreds cleanly, melts into stretchy strands, and browns without releasing too much water. It has a saltier, slightly tangier flavor than fresh mozzarella and a much longer shelf life. This is the cheese you want for pizza, baked pasta, and grilled sandwiches.
Buffalo Mozzarella
Mozzarella di Bufala Campana is made from the milk of water buffalo in southern Italy and carries a protected designation of origin. Buffalo milk is richer and higher in fat than cow's milk, giving this mozzarella a more pronounced flavor — tangy, grassy, and intensely creamy — with a softer, more yielding texture. It's prized for eating fresh, where its richness can shine, and is generally considered the finest mozzarella for a simple plate with tomatoes or prosciutto.
How to Choose and Use Each Type
Reach for fresh mozzarella when the cheese is the star and won't be cooked hard. Choose low-moisture mozzarella when you need reliable melt and browning. Splurge on buffalo mozzarella when you want the fullest flavor and plan to eat it raw. If you must use fresh mozzarella on pizza, slice it ahead and pat it dry, or let it drain, to avoid a watery result.
Storing Mozzarella
Keep fresh and buffalo mozzarella in their liquid and use within a few days of opening. Low-moisture mozzarella keeps far longer, sealed in the fridge, and freezes reasonably well for cooking.
Frequently Asked Questions
Is buffalo mozzarella made from buffalo meat?
No — it's made from the milk of water buffalo, not from any meat.
Why is fresh mozzarella stored in water?
The liquid keeps the soft cheese hydrated and protects its delicate texture, since it has no rind.
Which mozzarella is best for pizza?
Low-moisture mozzarella, because it melts and browns well without releasing excess water. Drained fresh mozzarella works for thinner, higher-end pizzas.
