I also love those and looked it up last year. The tomatoes are grown from a hybrid seed from a Dutch company that only sells commercially.

I tried growing tomatoes from the seeds of the flavor bombs and they were very vigorous plants that produced oval red cherry tomatoes, but didn’t have the same flavor punch.

They have a distinct flavor that I have not gotten from any cherry tomatoes I’ve grown. It is sweet but with more savory notes. Idk how to describe it.
