Mozzarella: Fresh Italian stretched-curd cheese

Production and characteristics

After milk is acidified and coagulated with rennet, the curd is cut and heated. The warmed curd is kneaded and stretched until it becomes smooth and elastic, then shaped and cooled in water or a light saline solution. Fresh mozzarella has a high moisture content, a soft texture, and a delicate, milky flavor. Low-moisture types are drier and are often used where longer shelf life and stronger browning are desired.

Varieties

• Mozzarella di bufala — made from water buffalo milk; known for creaminess and tang.
• Fior di latte — made from cow's milk; common, slightly firmer than bufala.
• Bocconcini and ciliegine — small balls, used in salads and appetizers.
• Smoked and aged variants — include scamorza and smoked mozzarella, with firmer texture and stronger flavor.
• Sheep and goat versions — in parts of Italy producers make mozzarella-like cheeses from sheep (sometimes called mozzapecora) and from goats' milk, the latter promoted because goats' milk can be easier to digest for some people.

Uses and culinary importance

Mozzarella is widely used in both fresh and cooked dishes. It is a classic topping for pizza, the key component of a Caprese salad, and a favorite in panini and baked pasta. Fresh balls are often served simply with tomato, basil and olive oil; low-moisture loaves melt well for gratins and sandwiches.

Storage and handling

Fresh mozzarella is perishable. It is commonly stored in a light saline liquid or brine to preserve moisture and flavor and should be kept in the fridge. Use within a few days for best texture; freezing is possible but usually degrades the soft, elastic quality. When using in hot preparations, allow the cheese to drain and come closer to room temperature for more even melting.

History and regional notes

Origins of mozzarella lie in southern Italy, particularly the Campania region, where water buffalo were historically raised for milk. Regional traditions produced distinctive local names and techniques. In some central and island regions producers adapted the method to sheep's milk — examples appear in Sardinia, Abruzzo and Lazio. Over time the cheese spread worldwide and now exists in many commercial and artisanal forms.

Notable distinctions

Key differences to remember are milk source (buffalo vs cow vs sheep/goat), moisture level (fresh vs low-moisture), and treatment (smoked or aged). These factors determine flavor, texture and best culinary use. For consumers seeking authenticity, look for regional designations and traditional producers; for everyday cooking, fior di latte and low-moisture mozzarella are convenient and versatile.
