San Marzano Redorta
Redorta is a larger Italian selection named for a Bergamo peak, not the DOP San Marzano.
Origin & history
The Italian paste standard from the volcanic plain below Vesuvius, where the true DOP-protected canning tomato is still grown. Long, blocky, low-seed fruit that defined what sauce tomatoes should be.
