Brocciu AOP — Corsican Whey Cheese: Seasonal Production and Technique

Corsica, France — island-wide production. AOP since 1983; EU AOP 1996. Production season: November–June only.

Brocciu is the foundational dairy product of Corsican cuisine — not simply a cheese but a culinary system. It is made from the whey left after pressing Corsican sheep or goat cheese, enriched with 15–25% whole sheep-milk or goat-milk, then heated slowly to 80–90°C. As the temperature rises, the whey proteins — principally lactalbumin and lactoglobulin — denature and aggregate into soft white curds that float to the surface. These are scooped with a perforated ladle into traditional conical rush baskets — fiscelle di giunco — that give brocciu frais its characteristic ridged surface. The production window runs November through June, tied to the lactation cycle of Corsican sheep and goats on their maquis pasture. Outside this window, brocciu cannot be made — the AOP prohibits summer production. After 21 days of salting and draining, fresh brocciu becomes brocciu passu (aged brocciu), a firmer, more pungent product with a dry rind. Brocciu is the only French AOP cheese made from whey, placing it technically closer to Italian ricotta than to any French cheese — yet its flavour is distinct: the maquis-herb character of the island's pasture, the specific Corsican sheep breeds, and the rush-basket imprint make it irreproducible elsewhere.

• Ricotta di pecora (Italy — whey-based parallel, lower enrichment ratio)
• Brousse du Rove (Provence — goat-whey cheese, French mainland cognate)
• Sérac (Alpine — whey cheese from cow milk, different base animal)

Silken-fresh, faintly lactic, sheep-milk sweetness with maquis-herb pastoral note; mild salt; delicate — strongest flavours are pasture and season rather than cheese-specific.
