São Jorge Cheese Making

Queijo de São Jorge

The making of Queijo de São Jorge — a firm, sharp, well-aged cow's milk cheese from São Jorge island in the Azores, made using a technique brought by Flemish settlers in the 15th century and adapted to the island's distinct volcanic pasture. Unlike the mainland Portuguese cheeses (Serra da Estrela CRAFT-1126, which uses cardoon vegetable rennet), São Jorge uses traditional animal rennet and a long aging period (minimum 3 months, often much longer) that produces a hard, piquant cheese closer in character to a Dutch Gouda or aged cheddar than to any mainland Portuguese tradition. The queijeiro reads the rind development by a combination of color and a specific knuckle-tap resonance test.

Community / Ethnic Group
Jorgense / Açoriano
Estimated Origin
15th century (Flemish settlers brought to the Azores under Portuguese crown sponsorship from the 1460s introduced Dutch-style cheese-making technique, adapted over centuries to the volcanic island pasture and climate); DOP Queijo São Jorge 1996
Cultural Function
Queijo de São Jorge is the most commercially significant Azorean food export and the island's primary economic activity — its DOP status and distinctive sharp, piquant character (distinguishing it from every mainland Portuguese cheese tradition) make it the clearest example of the Flemish settlement's lasting cultural and culinary imprint on the Azores
Primary Materials
Cow milk (from São Jorge island volcanic pasture — DOP requirement restricts production to the island); animal rennet (distinguishing this tradition from the mainland Serra da Estrela vegetable-rennet approach CRAFT-1126)
Primary Tools
Large cheese vat and press (sized for the 25–35kg wheel format); aging shelving; the knuckle (for the multi-point tap resonance test)
Process Overview
Milk coagulated with animal rennet; curd cut and cooked; pressed into large 25–35kg wheels; salted; aged for a minimum of 3 months with periodic multi-point knuckle-tap and color monitoring, often extended considerably longer for premium sharp grades
Traditional Applications
Table cheese (primary, especially for sharp aged grades favored for grating and strong flavor applications)
Contemporary Applications
Major Portuguese cheese export (the most commercially significant Azorean food product); international cheese retail; gastronomy
Notable Practitioners
São Jorge island dairy farms; Cooperativa de Lacticínios de São Jorge; approximately 1,000+ contributing farms
