I bought this brand at a grocery store and by chance am cooking side by side with a can of DOP San Marzano tomatoes from Dani Coop. Major difference is this San Marzano brand apparently (from what I read on internet) is San Marzano variety of plum tomatoe that they grow in Italy except it is grown in California under different conditions. The San Marzano brand is much lighter, almost watery flavor and it does not immediately breakdown i.e. still alot of chunks after slow cooking for 30 minutes. The Dani Coop had intense flavor, a bit on the acidic side and immediately brokedown into a sauce once I put it on the burner. There is a major difference in price as the Dani Coop is around the same price as the SM brand except it is 14.1 oz instead of 28 oz. I would not buy the SM brand again given I was deceived on the San Marzano label (and the expensive price!). I will try other San Marzano brands.
