What does the recent cold in the Midwest mean for grapes?

It means if they are Vitis vinifera, they are probably all dead now. The classic European winegrapes have little resistance to extreme cold (or to various fungal diseases). But their sturdier American and Asian grape-friends have excellent cold resistance--often down to -40F!, whereas vinifera will die off at about 0 degrees F (and the Amer and Asian grapes have excellent disease ressistance, too). This is why I'm supporting grapes that are crosses between the classic winegrapes (vinifera) and the American and Asian grapes. These modern grapes also ripen earlier. The modern grapes are a win-win-win in every sense.


If you want to talk about foolishness, real foolishness is the expensive and time-consuming planting of Vitis vinifera in the Midwest, when those grapes just cannot live there. Those growers should be planting modern grapes instead. Modern grapes make great wine. When will they learn? It's a little hard to feel too sorry for them.
