Mozzarella di Bufala in Paestum: Farms, Dairies and the Greek Temples

Paestum, near Salerno in Campania, is famous for two things that would seem to have nothing to do with each other: three of the best-preserved Greek temples in the world, and the home of Mozzarella di Bufala Campana PDO. The combination — Doric columns rising from a flat coastal plain surrounded by water buffalo grazing on spring grass — is one of the stranger and more memorable sights in southern Italy.

What is Mozzarella di Bufala Campana PDO?

The cheese received PDO (Protected Designation of Origin) status in 2008. To carry the designation, the milk must come from water buffalo herds raised within the designated zone (covering parts of Campania, Lazio and Molise), and the entire production process — curdling, spinning, shaping and packing — must take place within the same zone. The buffalo is not simply a cow alternative: buffalo milk has roughly twice the fat content and distinct mineral characteristics that give the cheese its signature creamy richness and clean, lactic flavour.

How Mozzarella di Bufala is Made

The production process is straightforward but unforgiving of shortcuts. Raw milk is heated and passed through a cream separator. Natural whey from the previous day’s production is added to curdle the milk; the curds are then matured in large tubs until they reach the correct pH. At the spinning stage (filatura), hot water is added to the curd mass, which is stretched and folded until it becomes smooth and elastic. The stretched curd is pinched off into balls — the word mozzarella comes from mozzare, to cut — and immediately placed in cold water to firm up. The finished balls are packed in their own whey. The best mozzarella is eaten the same day; flavour deteriorates within 24-48 hours of production, which is why locals argue that anything sold outside the region is a lesser product.

The Mozzarella Road and Farms to Visit

A cluster of buffalo farms and dairies lines the SS18 south of Paestum — locally known as the “Mozzarella Road.” Most dairies welcome visitors for the production process, which wraps up by late morning; arrive before 11am to see the spinning stage. Production is fully automated at the larger facilities, though a few smaller dairies still shape by hand.

Notable farms include Tenuta Vannulo, perhaps the best-known, an organic estate that also produces buffalo-milk gelato, yoghurt and soap; guided tours are offered in several languages but must be booked in advance. Caseificio Il Granato and Caseificio Salati are smaller operations where the process is more visible and the atmosphere less formal.

The Greek Temples of Paestum

The Paestum archaeological site is among the finest in Italy outside Sicily. Three Doric temples survive in extraordinary condition: the Temple of Hera (6th century BC), the Temple of Neptune (5th century BC, actually dedicated to Hera) and the Temple of Ceres (late 6th century BC, later converted to a Christian church). The National Archaeological Museum on site holds the famous tomb paintings including the Diver’s Tomb, one of the only surviving examples of ancient Greek figurative painting.
