"Coming from Italy, I'm always amazed how large US tomatoes/zucchini/eggplants/etc are, and those big, watery vegetables are almost always tasteless in comparison." From Melbourne, @SamBam what do think is the reason? My own personal observation, growing both Roma and large Beaf steak variety tomatoes in a home plot, is it's a combination of cultivar and heat. I agree on variety chosen. The commercial varieties are combinations of size, colour, season and preservation. Not necessarily taste. So it maybe the sugar content. Leave the tomatoes in that sun, pick them when they are ripe and the taste is there. Back at the supermarket, picked early and cooled... not so much flavour.
