About Quattro Colli
Quattro Colli (also written Quattrocolli) is a distinguished Italian cheese producer specialising in authentic Pecorino Romano DOP. Based in Valmontone in the Lazio Region, approximately 50 kilometres south of Rome, the company produces this iconic Italian hard cheese using traditional methods that date back to ancient Rome. Pecorino Romano PDO (Protected Designation of Origin) is one of Italy's most celebrated cheeses, made exclusively from fresh sheep's milk sourced from farms in the designated regions of Sardegna, Lazio, and Grosseto Province. Quattro Colli maintains the same artisanal finishing process that was perfected by the Ancient Romans, creating a cheese with distinctive sharp, salty flavour that has made it a cornerstone of Italian cuisine for millennia. The brand is part of the GSI group (Casa Modena-Parmareggio), one of Italy's leading companies in premium Italian cheeses. This group focuses on preserving and promoting Italian gastronomic traditions, offering an impressive portfolio that includes Parmigiano Reggiano, Grana Padano, Piave, Asiago, and other regional specialities alongside the Pecorino Romano. In the UK, Quattro Colli Pecorino Romano is available at major supermarkets including Tesco and Ocado, both as whole wedges and convenient pre-grated formats. The cheese is essential for authentic Italian pasta dishes like Cacio e Pepe, Carbonara, and Amatriciana, where its robust flavour profile provides the distinctive taste that cannot be replicated with other cheeses.
