Organic Greek Feta PDO: What the Double Certification Really Means

Most cheese labeled “organic feta” in American supermarkets fails one of two tests. Either it’s organic but not real feta (cow’s milk, made in Wisconsin or California), or it’s authentic Greek feta without organic certification. Finding cheese that passes both tests is genuinely rare, and understanding why requires looking at what each certification actually demands.

Alpha Omega Imports carries Roussas Organic Feta PDO, made by the Roussas family dairy in Almyros, Thessaly — one of the few cheeses on the American market that carries both stamps. Here’s what goes into that, from the pasture to the brine barrel.

First test: what PDO legally requires

Feta is not a style of cheese. Under EU law, it’s a Protected Designation of Origin, which means the word itself is legally reserved. To be sold as feta in Europe, a cheese must be produced in specific designated regions of Greece, made from sheep’s milk or a blend containing no more than 30% goat’s milk, from animals raised on local pasture, and brined and matured for at least two months.

That last detail about local pasture matters more than people realize. The flavor of PDO feta comes from what the sheep and goats eat: the wild herbs, thyme, and grasses of the Greek countryside. It’s the same principle as terroir in wine. A feta from Thessaly tastes like Thessaly.

Second test: what organic certification adds

Organic certification operates on top of the PDO rules, not instead of them. For a Greek dairy, going organic means every farm supplying milk must be certified under the EU organic standard: no synthetic pesticides or fertilizers on the grazing land, organic feed, strict animal welfare requirements, and annual third-party audits with full traceability from flock to cheese vat.

Here’s the part that explains why so few Greek dairies bother. PDO feta already requires local sheep’s and goat’s milk, which is in chronically short supply in Greece. Certified organic milk is a fraction of that fraction. A dairy committing to organic PDO feta is voluntarily narrowing its milk supply to the scarcest tier available, and paying a premium for it. Most producers don’t. The ones who do tend to be family operations with long-standing relationships with specific organic farms.

The dairy behind ours: Roussas of Almyros

The Roussas dairy sits in Almyros, a small agricultural town in Thessaly at the foot of Mount Othrys, in one of the officially recognized PDO feta zones. If you’ve shopped with us before, you already know their classic feta: it’s our best seller, barrel-aged, made with the traditional sheep and goat’s milk blend.

Their organic feta earned 2 stars at the Great Taste Awards, one of the most rigorous blind-tasting competitions in the food world, and it carries a stack of certifications that is genuinely hard to find on one label: PDO, USDA Organic, DIO organic certification, and kosher. The ingredient list is four items long: organic pasteurized sheep’s milk, sea salt, cultures, and microbial rennet, which also makes it suitable for vegetarians.

Notice something in that list? Only sheep’s milk. And that’s not an accident.

Sheep only, or sheep and goat? The two faces of real feta

A question we get constantly: is the “best” feta pure sheep’s milk, or the traditional blend with goat’s milk? The honest answer is that both are authentic, and they taste meaningfully different.

The blend is what most Greeks mean by classic feta. Goat’s milk gives feta its bright white color, its firmer, crumblier structure, and the peppery bite at the finish. That’s the profile of our classic Roussas Feta PDO, made from a sheep and goat’s milk blend.

Pure sheep’s milk feta is the other tradition: creamier, richer, more buttery, with a gentler, sweeter tang. Sheep’s milk is nearly twice as rich in fat and protein as goat’s milk, and when it stands alone, the resulting cheese is noticeably more luxurious on the palate. That’s Roussas Organic Feta.

There’s also a practical reality behind the choice. Organic sheep’s milk is already among the scarcest dairy supplies in Greece, and organic goat’s milk is scarcer still. A 100% organic sheep’s milk feta is the version a dairy can actually produce consistently, year round, at PDO quality.

So which one should you buy?

Both, honestly, because they serve different moments. The classic blend is the feta for a horiatiki salad, where you want that salty, peppery edge cutting through tomato and cucumber. The organic pure sheep’s milk version shines where creaminess matters: whipped feta dips, baked feta pasta, pairing with honey and figs, or eaten on its own with good bread and olive oil. And if certified organic sourcing is a priority for your table, the choice makes itself. Most cheese sold as “organic feta” on American shelves is domestic cow’s milk cheese, which isn’t feta at all. An organic PDO sheep’s milk feta from Thessaly is a different category entirely.
