I lived almost 7 years in Germany, and the average tomato at a supermarket was lightyears beyond the US. Then farmers markets are even better.

Funny enough, the further east you go, the better they taste.

But tbf, only for a few months when the many small farmers grow them outdoors and sell them for unbelievably cheap.

Rest of the time it's greenhouse tomatoes like everyone else.

I am willing to participate in a blind taste test to resolve this issue.

Yep. You have to grow own tomatoes to have good ones. Which is something only few people are willing and have option to do.

Except the available seeds are probably decreasing in quality as well.

No, there are places dedicated to preserving and making available heirloom seeds.

Is there a market for good tasting tomato seeds? :D

It's actually fascinating - I remember my grandmother scooping out the seeds out of vegetables and drying them, to be used next year.

The villagers also traded them as apparently they had different varieties.
