Grandpa and Mines Grapes.. - Grandpa started out growing Green Grapes... Well I did not know as a child. That there was a difference between Wild Grapes, and Green Grapes... So I planted Wild grape seeds after I ate them all over around Grandpa's grapes... One year ... His Grapes were not green no more... It has not effected any of the wild Grapes, but his grapes are now twice a huge and cross polination between wild grapes and purple ones. They are extra thicked skinned, have huge seeds but are very very tastey, Thick enough so that we learned by mistake one year when we started eating the fermented grapes we could get drunk off them... oopsies!:) .. So we make sure we harvest the grapes sooner and all seeds from our grapes we spit onto napkins rinse off and then sprinkle around the remaining grapevines...
