'source' as in obviously a different place in Greece vs. wherever they came from there to (US?) 'variety' as in among those that are available - maybe what you can get grown easily and cheaply in Greece/med is much better than that in the US, which is perhaps also local but necessarily (or for better yield) a different variety, so if you don't pay any attention to it you get something different. My point is it's not just passage of time that changed but also where they came from. If you think all tomatoes everywhere are (now) tasteless and you're one of the few enlightened ones who have realised this, you are absolutely kidding yourself.
