After many years of trialing SNFLA, I've finally had mixed results. The early tomatoes were great. Then after three rain storms in one week the next batch to ripen were almost bland, interiors were mushy and also had puffiness. The late ones returned to having great flavor.
This tomato should not taste sweet. In ideal growing conditions, it, for me, is firm, with a rich tangy flavor. No sweetness, and no tartness.
Filling in the history, thanks to Neil Gillard from Ontario ("retiree" here at T'ville) who saw the J.O. initials and suspected it was Jason Olson from Kansas. He contacted Jason and confirmed that seeds were sent to David Lemasters, and then David sent them to me. Jason's original source was Heirloom Seeds. He still has his original seed pack (Red Brandywine) from 1999.
