Here are some Black Vernissage fruits. I saved seeds from them. The plant was stunted until other plants had already been big for a good while. However, it was the first tomato to sprout, I believe. I think a disease stunted it. I zapped the seeds (so, I'm curious to see how they perform next time).
The fruits were firmer than I expected, and pleasantly so. The taste was a bit sweet. It was good. It wasn't all that different from Noire de Crimee' (but it was different). The fruits weren't much smaller, either.
