San Marzano Tomatoes P.D.O.
Choose options
San Marzano tomatoes (Solanum lycopersicum) — the plum tomato from the volcanic plains south of Vesuvius that has become the benchmark for sauce-making worldwide. These hold P.D.O. (DOP — Denominazione di Origine Protetta) status, meaning they are grown within the designated area around San Marzano sul Sarno near Naples, in the mineral-rich volcanic soil that defines the variety's character. The combination of that soil, the Mediterranean climate and the specific growing conditions of the Sarno valley produces a tomato with a flavour profile that has never been convincingly replicated elsewhere.
San Marzano tomatoes are longer and more pointed than standard plum varieties, with a thicker flesh, fewer seeds and less water content. The flavour is concentrated, sweet and notably low in acidity — which is exactly why they became the foundation of classic Neapolitan sauce. Where other tomatoes need sugar to compensate for sharpness, a good San Marzano does not. The dense, meaty texture breaks down into a smooth, rich sauce with minimal effort: crush by hand, cook gently with garlic and olive oil, and the tomato does the rest. They are equally good eaten fresh — sliced into salads, on bruschetta, or simply with salt and olive oil — though their reputation rests on what happens when they meet a pan.
