A European grape like Cabernet Sauvignon only does well in California, maybe the northwest. They can't handle the cold in the northern united States or the heat of the south besides not being disease resistant. Kyoho might make it in a lot of places.
Even California has produced more resilient crosses. Ruby Cabernet is 100% vinifera cross of Cabernet Sauvignon but the wine flavors don't diminish in hot weather like Cabernet Sauvignon. Then they recently released grapes that are 94-96% vinifera with vinifera type berries but have a gene for pierce tolerance from vitis Arizonica. They have slightly better tolerance of fungus. But they were bred for California since traditional grapes are even having problems in Europe and California due to disease suceptiblity.
Europe has bred some vinifera quality hybrids but with improved disease resistance. Regent, malverina, laurot.
The ones for the north east or south eastern united states are a little more native need to be a little tougher but still good quality. Traminette or chardonnell etc for the north. Blanc du Boise, cab zehn etc in the south.
