The vines should have been exposed to a period of cold temperatures above
freezing for several weeks. The temps minght not be consistent, but enough
to put them in to dormancy and total defoliation. That way you know the
vines are asleep.

I don't let my roots freeze. Probably kill them. I unpot my vines on a cold
day, (less than 45 F). That way, the roots and vine can be wrapped after
being thoroughly wetted and shoved in a cooler at 34 - 40 F until spring.

If the wrapped vines are allowed to remain in temps above 40 there is a risk
of mold and/or rot.

Last year, before bringing the vines out of cold storage, their genetic
triggering already sent them into bud swell before pulling them out of the
bag. Some mold had formed on the roots, but nothing alarming, or rotten.
When in cold storage, remember to pull them out when the temperature is
steadily above 45 F.
