All natural. It all began in 1896 when young Teresa Marzetti arrived in the United States from Barga, Italy, and started her small Italian restaurant in Columbus, OH. Marzetti's became a local favorite and grew to become a four star restaurant and one of the finest dining experiences in the Midwest. After Teresa Marzetti's death in 1972, the restaurant closed forever, but her passion for quality still lives in Teresa's Select Recipes Salad Dressings. Made in USA.
