I grew this in 2016, overwatered, and it was one of the most acidic of a very non-acidic batch of tomatoes. It tasted good, and the fruits reliably each had the same a peculiar shape. I suspected it might not be true-to-type (although I'm not sure). So, I'm trying it again from TomatoFest seeds to compare, this year.
