Mutti Tomato Paste Double Concentrato was first produced in 1889. In 1951, this rich and intense tomato paste was put into a resealable tube to retain freshness. The fact that this tomato paste is double-concentrated gives it a deeper, more powerful flavor. Five-and-a-half pounds of Mutti's famous Italian tomatoes go into making just one pound of Mutti Tomato Paste Double Concentrato!
