How long do Jabo's hold on to the fruit ?
Im sure most people pick them as soon as they are ripe
but, if you happen to have a few large trees with a lot of fruit
(not that i will have that problem any time soon mind you)
it would be good to know they will keep on the tree for a while
depends on species or variety!
sabara can hold for a while, but u cant'really eat them when they first turn black!
they need to turn black, then hang on the tree for a few days or more...then they get a bit rubbery, and soft...this is when they're ready to eat...
but to be honest, it seems like the longer they sit on the tree,(without being molested by wildlife, mind you) the fruits develop a sweeter smoother pulp...up until the inevitable point, when they turn to wine.
the red jaboticaba is unique because it can be eaten at several stages...when partially green (it is tart, and a bit fibrous, but still good if you want to beat the birds)....or when fully red...when the fruit is quite sweet and tart, the skin is thicker when you chew, but comparable to sabara.....or finally when super ripe...the fruits turn a very deep wine red (or purple...not black), and become extremely rubber/soft to the touch...the pulp on the inside is silky smooth, and very succulent...the flavor is so sweet it's incredible...when you juice the fruit at this phase, it's too sweet to drink by itself..i found that it must be cut in half with water, or even use 1/4th juice and 3/4 water...and it will still be sufficiently sweet.
typically the fruits with thicker skins..like M. vexator, M.glazioviana, and P. edulis....can sit on the tree much longer than Sabara, trunciflora, red jabo, and others which are similar.....then you have those like the Grimal, which are in between, having a nice thick skin, that can really hang on the tree even longer than Sabara, but not as long as glazioviana....
the diversity is astounding! I only have experience with a fraction of what's out there in the world.
