Cheese

A 7,000-year-old technology

The oldest archaeological evidence of cheese-making comes from Kuyavia, Poland — perforated ceramic strainers dated to roughly 5,500 BCE that show milk fat residues. Cheese was a logical solution to two problems: most adult humans couldn’t digest fresh milk’s lactose, and milk spoiled rapidly. Fermenting and pressing it converted lactose to lactic acid (digestible) and concentrated the fat and protein into a storable form.

Categories by texture

Cheese roughly divides by moisture and aging:

• Fresh — ricotta, mozzarella, queso fresco; eaten within days
• Soft-ripened — brie, camembert; mold-ripened from outside in
• Washed-rind — taleggio, époisses, limburger; pungent
• Semi-hard — cheddar, gouda; aged months
• Hard — parmigiano, manchego, pecorino; aged 1-3+ years
• Blue — roquefort, stilton, gorgonzola; veined with mold cultures

Each category requires different microorganisms, salt levels, humidity, and aging conditions.

Protected names

Many traditional cheeses have legal name protection (PDO/DOP in Europe). Only cheese made in specific regions with specific methods can be called Roquefort, Parmigiano Reggiano, Gruyère, Stilton, or Feta. American “parmesan” is legally a different product.
