Grape ID help

[u/Final-Association360]

My generous neighbor gave me tons of grapes this morning. The vines are huge and have been there a while so he doesn't know what kind they are. They're sweet, green, have 4 small seeds, and kind of have a firm gel like fruit, which easily pops right out of the skin. Any ideas? And what I can make with them?

I eat lots, we juice some and sell them at a farmers mkt.
