My San Marzano tom's are quite small, about the size of cherry tom's maybe a tad larger but still tasty.  Is this because I used saved seed, F1 possibly but I cannot remember.

Cheers,  Tony.

San Marzano isn't an F1 variety, so I don't think that is why they are small.  Well, my packet is not an F1, but some varieties do have a 'name' attached and these seem to be F1.  What type did you grow?

I think you have mixed the seeds with others. San Marzano are a quite large tomato 150-200g is not unusual. There is a cherry plum tomato called  Piccolo that is F1 maybe the seeds got mixed up? I grow San Marzano tomatoes every year and have done for at least ten years and never had a small tomato from a crop even from saved seeds. It is a funny one though I assumed it was heir-loomed by now it is an old variety but three year ago I bought F1 hybrid San Marzano seeds from a shop in Italy, I am using the last of the seeds this year.

IIRC San Marzano Lungo (longer fruit) and San Marzano Nano (smaller plant and fruit) are both F1 Hybrids, but ordinary San Marzano is definitely not an F1.
You either got your seeds muddled up (likely) or they cross pollinated with a cherry variety (unlikely)

I've never seen Piccolos that are plum shaped, only round. I also don't think it's an F1 unless I've been very lucky with my saved seed!

Have a look here where you can get a supermarzano F1  as well same seeds I bought in Italy.

I suppose you could get the usual San Marzano confused with Supermarzano, but either way, it doesn't explain the cherry sized tomatoes 
Are the Supermarzanos really any better than normal ones?

I have grown different " oridinary Marzano's" from seed suppliers and saved seeds and got really nice tomatoes. Last year and this I have grown supermarzano F1 Last year I grew some really nice tomatoes which I thought had a slightly different, classic marzano, shape and were consistently sized . Was one a better producer than the other? Very difficult to say because there are far too many variables and I never really pay too much attention to actual yield. When it comes to flavour again it is difficult to say because they were grown in different years. But they were nice tomatoes he is a some of the supermarzano F1 that I took a photo of last year. I use these tomatoes manly for conservation but they are quite nice in a salad. It is notable that my nieghbour does not like them because the are too firm the French like really soft fleshed tomatoes like Marmande , coeur de bouffe and cornue des Andes... also in general BIG tomatoes.

I never knew my cat took a holiday with you last year, I know she was missing for a few days, but still! She could have sent me a postcard

We've got some San Marzano growing well, but now pear-shaped!

Might be a watering issue, as they are in pots in troughs, but - hey ho, who cares really!
