Mutti Whole Peeled San Marzano Tomatoes are grown in the Italian Agro Sarnese Nocerino region, between Naples and Salerno. They are D.O.P certified, which means that their origin and quality are guaranteed by the highest standards. These deliciously sun-ripened fleshy tomatoes are a vibrant red color, have a dense texture, and maintain a slightly acidic flavor from the volcanic soil in which they are grown.
