What Animal Does Mozzarella Come From?
Mozzarella, in its most authentic form, comes from water buffalo milk, though cow’s milk is a common and widely available substitute, particularly in North America and beyond.
Understanding Mozzarella: A Dairy Deep Dive
Mozzarella, beloved for its soft texture and mild flavor, is a staple in Italian cuisine and a favorite worldwide. But beyond its ubiquitous presence on pizzas and in salads, understanding its origins and production methods reveals a fascinating story of tradition, adaptation, and global dairy dynamics.
A Brief History of Mozzarella
The history of mozzarella is intertwined with the story of the water buffalo in Italy. These majestic animals were likely introduced to the country sometime during the Middle Ages. Their milk, richer in fat and protein than cow’s milk, proved ideal for cheesemaking. The traditional method, known as pasta filata (spun paste), was developed, involving stretching and kneading the curd in hot water to achieve its characteristic smooth, elastic texture. This artisanal process, handed down through generations, has made mozzarella a symbol of Italian culinary heritage.
The Two Main Types: Buffalo vs. Cow
While both buffalo and cow’s milk mozzarella share the same basic cheesemaking process, the resulting cheeses are distinctly different.
- Buffalo Mozzarella (Mozzarella di Bufala Campana DOP): Made exclusively from the milk of Italian Mediterranean buffalo, this type is known for its richer, slightly tangy flavor, higher fat content, and incredibly creamy texture. The DOP designation guarantees authenticity and adherence to strict production standards within the Campania region of Italy.
- Cow’s Milk Mozzarella (Fior di Latte): More widely available and generally less expensive, cow’s milk mozzarella offers a milder, more delicate flavor profile. Its texture tends to be firmer than buffalo mozzarella. This is the most common type found in supermarkets outside of Italy.
The Mozzarella Making Process
Whether using buffalo or cow’s milk, the basic process for making mozzarella involves the following steps:
- Pasteurization (Optional): While traditional methods often use raw milk, many modern producers pasteurize the milk to ensure safety and consistency.
- Acidification: The milk is acidified using a starter culture or citric acid. This process helps the curd to form.
- Coagulation: Rennet, an enzyme, is added to coagulate the milk, forming a solid curd.
- Cutting the Curd: The curd is cut into small pieces, allowing whey to separate.
- Heating and Stirring: The curd is heated and stirred to further expel whey.
- Pasta Filata (Spinning): The curd is submerged in hot water and stretched and kneaded until it forms a smooth, elastic mass.
- Shaping: The pasta filata is shaped into balls (bocconcini), braids (treccia), or other desired forms.
- Brining: The mozzarella is immersed in a brine solution to add flavor and preserve its freshness.
Nutritional Benefits of Mozzarella
Mozzarella, particularly buffalo mozzarella, offers several nutritional benefits:
- Good Source of Protein: Essential for building and repairing tissues.
- Rich in Calcium: Important for bone health.
- Contains Vitamins and Minerals: Including vitamin B12, riboflavin, and phosphorus.
- Lower in Sodium (Compared to other cheeses): Depending on the brine solution used.

|---|---|
| Calories | 280-300 |
| Protein | 18-22g |
| Fat | 22-25g |
| Calcium | 400-500mg |
| Sodium | 150-200mg |
(Note: These values are approximate and can vary depending on the milk source and production method.)
Common Mistakes When Buying and Storing Mozzarella
- Buying based solely on price: Lower prices often indicate lower quality, especially with buffalo mozzarella. Look for reputable brands or local cheesemakers.
- Ignoring the liquid: High-quality mozzarella is typically packaged in a milky liquid (whey or brine). This helps keep it moist and fresh. Avoid mozzarella that looks dry or has been sitting in its packaging for too long.
- Improper storage: Mozzarella should be stored in its original liquid in the refrigerator. Consume it within a few days of opening. Freezing is generally not recommended as it can alter the texture.
- Using pre-shredded mozzarella: While convenient, pre-shredded mozzarella often contains cellulose to prevent clumping, which can affect its melting properties. Opt for fresh mozzarella and shred it yourself for the best results.
Frequently Asked Questions (FAQs)
Is all mozzarella made from buffalo milk?
No. While authentic Mozzarella di Bufala Campana is exclusively made from buffalo milk, much of the mozzarella available in supermarkets is made from cow’s milk.
What is the difference between fresh mozzarella and low-moisture mozzarella?
Fresh mozzarella, also known as fior di latte, is typically packaged in water and has a soft, delicate texture. Low-moisture mozzarella is drier and firmer, making it ideal for grating and melting on pizzas.
How can I tell if mozzarella is made from buffalo or cow’s milk?
The label should clearly indicate the type of milk used. Buffalo mozzarella will usually have the DOP label and is typically more expensive. Also, buffalo mozzarella tends to be creamier and slightly tangy.
Does buffalo mozzarella taste different from cow’s milk mozzarella?
Yes. Buffalo mozzarella has a richer, more complex flavor and a slightly tangy aroma. Cow’s milk mozzarella is milder and more neutral in taste.
Is buffalo mozzarella more nutritious than cow’s milk mozzarella?
Generally, yes. Buffalo mozzarella tends to have a higher fat and protein content, as well as higher levels of calcium and other minerals.
Can I make mozzarella at home?
Yes! While it requires some practice and patience, it is possible to make both buffalo and cow’s milk mozzarella at home. There are many recipes and kits available online. The pasta filata step is often the most challenging.
What is burrata, and how is it different from mozzarella?
Burrata is essentially a mozzarella shell filled with stracciatella, which is shredded mozzarella soaked in cream. It is incredibly rich and creamy compared to regular mozzarella.
Is it safe to eat the liquid that mozzarella comes in?
Yes, the liquid is typically a mixture of whey or brine, which is safe to consume. However, it may have a slightly salty or acidic taste.
Why is some mozzarella yellow?
The color of mozzarella can vary depending on the diet of the animal. Mozzarella from grass-fed cows or buffalo may have a slightly yellowish tint due to the presence of beta-carotene. It does not indicate spoilage.
How long does mozzarella last?
Fresh mozzarella is best consumed within a few days of opening. Low-moisture mozzarella can last a bit longer, but it’s always best to check the expiration date. Always store it properly in the refrigerator.
Can I freeze mozzarella?
Freezing mozzarella is generally not recommended as it can change the texture, making it grainy and watery. However, if you must freeze it, wrap it tightly in plastic wrap and then place it in a freezer bag.
Is mozzarella lactose-free?
Mozzarella is not naturally lactose-free, but some brands offer lactose-free versions. The fermentation process can reduce the lactose content in some cheeses, but it’s important to check the label if you have a lactose intolerance.
