San Marzano tomatoes, a variety of plum tomatoes, are considered by many chefs to be the best plum tomatoes in the world.[1]


Compared to the Roma tomato, San Marzano tomatoes are thinner and more pointed. The flesh is much thicker with fewer seeds, and the taste is stronger, sweeter and less acidic. Many people[who?] describe the taste as bittersweet.

The San Marzano vines are indeterminate and have a somewhat longer season than other paste tomato varieties, making them particularly suitable for warmer climates. As is typical of heirloom plants, San Marzano is an open-pollinated variety that breeds true from generation to generation, making seed saving practical for the home gardener or farmer.

Commercial production and use[edit]

Amy P. Goldman calls the San Marzano "the most important industrial tomato of the 20th century"; its commercial introduction in 1926 provided canneries with a "sturdy, flawless subject, and breeders with genes they'd be raiding for decades."[2] Though commercial production of the San Marzano variety is most closely associated with Italy, seeds for the variety are available worldwide, often labeled as an heirloom variety.[citation needed] Canned San Marzanos, when grown in the Valle del Sarno (valley of the Sarno) in Italy in compliance with Italian law, can be classified as Pomodoro S. Marzano dell'Agro Sarnese-Nocerino and have the EU "DOP" emblem on the label.

Brands available in supermarkets include Cento, Nina, La Bella, Solinia, Vantia, La Valle and Strianese.[citation needed] Most San Marzano tomatoes sold commercially are grown in Italy, though they are produced commercially in smaller quantities in other countries. Because of San Marzano's premium pricing, there is an ongoing battle against fraudulent product. On November 22, 2010,[citation needed] the Italian carabinieri confiscated 1,470 tons of canned tomatoes worth 1.2 million of improperly labeled product.

San Marzano tomatoes have been designated as the only tomatoes that can be used for Vera Pizza Napoletana (True Neapolitan Pizza).[3]


One story goes that the first seed of the San Marzano tomato came to Campania in 1770,[citation needed] as a gift from the Viceroyalty of Peru to the Kingdom of Naples, and that it was planted in the area that corresponds to the present commune of San Marzano sul Sarno. They come from a small town of the same name near Naples, Italy, and were first grown in volcanic soil in the shadow of Mount Vesuvius.[citation needed]

In the United States, San Marzano tomatoes are the genetic base for another popular paste tomato, the Roma tomato. The Roma is a cross between a San Marzano and two other varieties (one of which was also a San Marzano hybrid),[2] was introduced by the USDA's Agricultural Research Service in 1955.[4]
