'Rejected' Grapes for White Wine

Aromella, in 3 years very little growth with diseased leaves, mid-season, zone 4b

Cayuga White, unhealthy plant with diseased leaves, early to mid-season, zone 5.

Delaware, low vigor, diseased leaves, early, zone 5b.

​Dilemma, diseased, low vigor, mid-season, zone 5b.

Frontenac Gris, healthy some years but heavily diseased others, not very tasty fresh nor as wine, mid to late, zone 3b.

Geisenheim 318, unhealthy plant with diseased leaves resulting in lack of ripening,
it died to ground level winter 2017-2018 but started new shoots Spring 2018 which again were unhealthy, so pulled out this vine, late, zone 5a.
13.8 Brix on Oct 4, 2017

Kay Gray, healthy but fair to poor taste fresh on my site, not for wine making. In a warmer climate, they are said to taste better. In our climate, we can do better with other varieties, early, zone 2b.

La Crescent, diseased, no growth, all leaves died, early, zone 3b.

Monastery Muscat, poor growth with diseased leaves, zone 5b

New York Muscat, diseased leaves, delicious grapes but most of them rotted away before ripening, mid-season, zone 6.
​

Orion,  diseased, stunted growth, mid-season, zone 4.

Osceola Muscat (ES 8-2-43), diseased, delicious grapes but most of them rotted away before ripening, early, zone 4a.

Ravat34, diseased, stunted growth, died over winter, however is said to have good disease-resistance, tried it in two locations without success, a winery in British Columbia (Zone 6) reports it has trouble ripening in some years so it probably would not be good for our site, mid-season, zone 5.

Swenson White, tasty, diseased leaves and berries, berries are large, mid to late, zone 4a, 
18.1 Brix on Sept 26, 2018

Swenson White, diseased leaves.

Traminette, diseased, stunted growth, most leaves died, late, zone 5.

Valvin Muscat, diseased, stunted growth, most leaves died, requires grafting to be productive however, I do not want to deal with grafted vines since they are too labor intensive to protect the vines during winter, mid-season, zone 5b to 6a.

Vidal Blanc, diseased, stunted growth, late, zone 5 to 6.

Wild White, healthy large berries but would not ripen on our site. Also it gets attacked by grape wine borer, guessing mid to late, guessing zone 4.
