Grapes need lots of warm days to ripen and they only ripen on the vine. This used to make growing grapes in zone 5 or colder difficult if not impossible but newer varieties of cold hardy grapes makes growing grapevines for zone 5 promising. Read on to find out about these cold hardy zone 5 grape varieties.
Growing Grapes in Zone 5
In cooler regions, choosing the correct varietal is crucial. They need to be able to mature before the first frost hits. Even with cold hardy grape varieties, the northern gardener will probably be leaving the grapes on the vine well into early fall, sometimes up to the first killing frost of the season.
This puts the grower into a perilous area. The grapes won’t ripen off the vine, but a hard freeze will ruin them. An ongoing taste test is the only true way to see if the grapes are ready to harvest. The longer they are left on the wine, the sweeter and juicier they become.
Hardy grape varieties are bred using indigenous grapes found throughout the eastern half of northern North America. Although the fruit of this regional grape is small and less than tasty, it is very cold hardy. So breeders cross bred these grapes with other varieties of wine, table and jelly grapes to create hybrid
Zone 5 Wine Grapes
There was a time when northern grape varieties lacked vineyard parentage, thus rendering them too acidic for winemaking. But today’s cold hardy grapes have been bred to be higher in sugars, so zone 5 wine grapes are now available to northern growers. The list of these suitable wine grapes is now quite extensive.
