Tupí (Fermented Cheese)

Tupí is a traditional Catalan strong fermented cheese paste, among the most pungent and intensely flavored cheeses in Spain. It is produced by fermenting and curing cheese curds—traditionally sheep's milk, sometimes cow's milk—with brandy, pomace spirit (augardiente), or wine. The curds are packed into clay vessels called tupís, which give the cheese its name and create the anaerobic conditions necessary for the slow fermentation process. During aging of several months or longer, the alcohol partially evaporates and the paste develops its characteristic sharp, almost biting flavor with lingering alcoholic undertones that reflect the original spirit used. The result is a smooth, dense, spreadable paste ranging from pale cream to light yellow.

This represents an endangered traditional craft, with production now limited to a handful of artisanal producers in Catalonia's mountain regions, particularly the Pyrenees foothills and the province of Girona. The intense concentration means that a small amount delivers enormous impact—a quality that defines Tupí's role in Catalan cuisine. Authentic artisanal Tupí, cured in clay pots and sourced directly from Catalan cheesemakers or specialty retailers, develops far greater complexity than industrial versions. When purchasing, seek out producers who follow the traditional method: the difference in depth and character is substantial.
