Food has fun history. Like the root rot that happened across France and Italy that almost wiped out the grape vineyards. They were saved by grafting some of them and transporting them to California, and then they found out the root systems in California were immune to the root rot occuring in France/Italy so they were able to move some of those plants back. Not saying that all of California’s wine comes from those grafted plants, but I wonder how much of an impact they had on turning California into the wine creators they are today.
