San Marzanos are great indeed for sauce. I grew them last year. I am considering them again. However, I was a bit disappointed in their yield. While many tomatoes grew, they tended to be smaller than expected. They were more like the size of romas, and I was expecting them to be larger. Some were larger, but most were on the smaller side.Consider San Marzanos for sauce...if you can grow them. I tried them last year and they were both prolific and delicious.
