Here in the far northeast of Portugal, too. Also, lots of rye, buckwheat, and all sorts of crazy cultivars of other stuff - they grow lettuce here that bolts a meter tall without any loss of flavour, and jersey walking sticks, yellow (on the inside too) watermelons with huge seeds - all sorts - because they still grow the same village/family seed stocks their medieval ancestors did, and a lot of stuff is hyper-adapted to the local climate.
Also larger things like figs and grapes - only after you spend a few years here do you learn that dona olema has one particular fig tree that tastes like melon, and senor rodrigo has a grape vine that makes gigantic (billiard ball sized) ridiculously sweet grapes. This knowledge doesn’t travel to the next valley over, even. Oh, and then you find another vine, the same, climbing a tree in a forest that was a vineyard 70 years ago.
Kinda amazes me how much genetic diversity for crop cultivars there still is, smack under our noses, across Europe.
Funny that I grew up in rural north portugal and never heard of any of this bs
Gigantic grapes sound awesome, so did a quick check. Assuming 5–6 cm in diameter, this appears to far exceed the size of any known grape variety.
