Finally, taste test time, and I must say I'm most impressed with the first of the season.
First (from bottom up), was have the Galina x Grub's Mystery Green F1 (canary yellow) - a lovely burst of flavour with much more depth than Galina; rich, deep nice "acid"/sweet balance. Only down side - skin slightly tough and a wee bit small.
Next up is Grushovka (pink) - smooth, light, tasty, on the sweet side - yum. Plant health and production make this one a keeper.
Then we have Persey (red) - have grown this one a few times - rich (but not the depth of others tasted today), sweet, nice "acid", "crispy".
Finally, in top pic, Shtambovy Kartofelnolistny 164 (pink), wow! - a real surprise standout, nice "acid" bite, rich, deep taste and colour - with sweet notes - PL dwarf and pink (clear skin) - a rather rare combination I believe.
Lots of green tomatoes starting to lighten up - now if they all taste as good as these four I will be more than pleased - even if they are late .......
