A unique tomato
The characteristics that make the San Marzano Tomato unique and distinguishable from all others are very specific.
The fruits have a typical elongated shape and usually measure between six and eight centimeters; when ripe, the color is bright red.
The thin skin peels off easily, enclosing firm, fleshy pulp with few seeds.
The interior has two or three chambers and the taste is typically strong, sweet and sour.
The dense, fleshy pulp ensures that San Marzano does not crush during processing, producing firm peeled tomatoes and consistent sauces.
