How Is Feta Made?

Feta is a brined curd white cheese made from sheep’s milk or a mix of sheep’s and goat’s milk. The process starts by adding rennet to warm milk to form curds, which are then cut, drained, and pressed into blocks. These blocks are salted and aged in a brine solution for at least two months, giving feta its signature tangy, salty flavor and crumbly texture.

What is feta cheese exactly?

Feta is a protected designation of origin (PDO) product in the European Union. This means only cheese made in specific regions of Greece, using traditional methods, can legally be called feta. The milk must come from sheep or a mix of sheep and goat milk, with goat milk making up no more than 30 percent of the blend.

The PDO rules also dictate the production process. The cheese must be aged in brine for at least two months. This brine aging is what gives feta its distinct salty taste and slightly grainy texture. Cheeses outside this PDO system are often labeled as “feta-style” or “white brined cheese.”

How is feta made step by step?

The process is straightforward but requires precision at each stage. Here is how traditional feta is made from start to finish.

1. Milk preparation. Fresh sheep’s milk, or a mix with goat’s milk, is pasteurized. The milk is then warmed to about 95°F (35°C). Starter cultures are added to begin the fermentation process.

2. Coagulation. Rennet, an enzyme that causes milk to thicken, is added. The milk sits for about 45 to 60 minutes until it forms a firm gel-like curd.

3. Cutting the curd. The curd is cut into small cubes, roughly the size of sugar cubes. This releases whey, the liquid part of milk. Smaller cuts mean a drier, firmer cheese.

4. Draining and molding. The curds and whey are transferred to perforated molds. The whey drains off over several hours. The curds are not pressed heavily — just enough to form a solid block.

5. Salting. The formed blocks are removed from the molds and dry-salted. Salt is rubbed onto all surfaces. This draws out more whey and starts the preservation process.

6. Brining and aging. The salted blocks are placed into containers filled with brine — a saltwater solution. They age at cool temperatures for at least two months. During this time, the cheese develops its tangy flavor and crumbly texture.

7. Packaging. After aging, the feta is packaged in brine or vacuum-sealed. It is stored refrigerated until it reaches you.

What milk is used for feta?

Authentic Greek feta uses sheep’s milk as the base. Sheep milk is higher in fat and protein than cow’s milk, which gives feta its rich, creamy mouthfeel despite being crumbly. Goat’s milk can be added, but it cannot exceed 30 percent of the total milk volume.

Sheep milk also has a different protein structure. It curdles more easily and holds together differently than cow milk. This is part of why feta has its characteristic texture — it is not rubbery like many cow milk cheeses.

Feta-style cheeses made outside Greece often use cow’s milk. These will taste milder and have a softer, less crumbly texture. They are also typically aged for less time.

How long does feta need to age?

Traditional Greek feta must age in brine for a minimum of two months. Some producers age it for three to six months for a stronger, more pungent flavor. The aging time directly affects the taste and texture.

Younger feta, aged around two months, is milder, creamier, and slightly more moist. As it ages longer, it becomes saltier, firmer, and more crumbly. The flavor becomes sharper and more tangy.

Commercially produced feta-style cheeses are often aged for only a few weeks. These lack the depth of flavor and the crumbly texture that comes from longer brine aging.

What makes feta different from other cheeses?

Feta stands apart because of its brine aging process. Most aged cheeses are air-dried or waxed. Feta stays submerged in a saltwater solution for its entire aging period. This gives it a high salt content and a tangy, acidic taste.

Another difference is the lack of a rind. Because feta is stored in brine, it does not develop a hard outer skin. The cheese remains uniform from edge to center.

The crumbly texture is also unique. Feta does not melt well when heated. It softens but holds its shape, which makes it ideal for salads and baked dishes where you want distinct pieces of cheese.

Is feta healthy?

Feta is a nutrient-dense cheese. A one-ounce serving (about 28 grams) contains roughly 75 calories, 6 grams of fat, and 4 grams of protein. It is also a good source of calcium and phosphorus, both important for bone health.

Feta is lower in fat than many aged cheeses like cheddar or parmesan. It also contains less lactose because the brine aging process breaks down much of the lactose. Many people with mild lactose intolerance can tolerate small amounts of feta.

The salt content is the main concern. Feta is high in sodium, often containing 300 to 400 milligrams per ounce. If you have high blood pressure or are watching your salt intake, eat feta in moderation.

Can you make feta at home?

Yes, you can make a feta-style cheese at home, though it will not be authentic PDO feta. The process requires rennet, cheese cultures, and a brine solution. You also need a consistent cool temperature for aging, around 50°F to 55°F.

Home cheesemaking kits are available and include the necessary cultures and rennet. The process takes about two to three hours of active work, followed by two months of aging. The result will be a white brined cheese similar to feta, though the flavor will depend on your milk source and aging conditions.

If you want authentic Greek feta, buy it from a reputable source. The flavor and texture from traditional production methods are hard to replicate at home without experience.
