Great question!
You can keep dormant canes in the refrigerator for about a year before they start to degrade. After 2+ weeks in refrigeration, the canes can be rooted. It takes about 6 months from budbreak to harvest. This time is the same in the greenhouse as it is in the vineyard. If the vines are grown in a greenhouse where day-length and temperature are controlled, it is possible to harvest 2 crops a year @ ~6 months apiece. We just take the canes out of the refrigerator when we start a new batch.
As a greenhouse (soil) grower of vegetables myself, is this actually feasible? Many plants produce based on chilling cycles or day length; do you envision swapping out plants midway through the season? I know for greenhouse blueberries and possibly raspberries it can be plausible to grow in pots and bring into greenhouse in stages just for the fruiting cycle but I don't know if grapes are daylength or cold sensitive.
