I think San Marzano is variety of Italian plum tomato sold by many packers. Muir Glen is a packing company who may also sell san Marzanos. So it may be their way of packing--or it could be just that batch.
And I totally agree with the poster that said her heirlooms will blow everything else out of the water!! BUT we can't have summer tomatoes all year long, unfortunately. ;o)
