What makes tomatoes SOUR and disgusting?

[hasshoes]

Okay. . . after pulling tons of plants I should be happy I getting a few sungolds that are tasty. . . but this whole scenario is such a tease!!!

Here's the deal:

I've been getting tons and tons of "Togo Trifel" that are so cute but utterly inedible. I mean, I could stand the mealy, but these actually smell rotten before you cut into them.

They taste hideously rotten and sour. Like, on a objective level I believe 100% of anyone that tasted them would go "eww" and gag.

I chalked it up to the variety and bad weather.

Well I finally picked a Paul Robeson yesterday. Cut it open. . . exact same nasty sour taste as the Togo Trifel. I mean, total 100% exact taste.

What is causing this? I would be inclined to think it was 'first tomato syndrome" but I've been getting these nasty Togo Trifels for weeks.

Can too much rain or overwatering be causing this? They are also mealy.

I may have over watered a few weeks ago because my moisture meter kept saying "dry". I didn't really water Paul so much though.

Thanks for any tips. I'll be sooo bummed if I finally make it past this Late Blight nonsense only to get rotten tasting maters!
