Canadice is a seedless red grape that brings both productivity and reliability to northern gardens, thriving in hardiness zones 5 through 8. This Cornell University licensed cultivar ripens reliably by mid-August, producing medium-sized, firm red grapes with a distinctive spicy-sweet flavor that works beautifully fresh, in salads, or pressed into juice and wine. The vines mature between 4 and 6 feet tall and spread generously on a trellis, bearing compact clusters even after harsh winters, making it an exceptional choice for gardeners in cooler climates who want a versatile, seedless harvest.

Canadice delivers consistent crops of firm, seedless red grapes with remarkable cold hardiness and a flavor profile that balances sweetness with a unique spicy character. The compact 6 to 8 inch clusters ripen in mid-August and hold well on the vine through September, giving you a long picking window. This variety was licensed from Cornell University specifically for growers seeking reliable performance in cooler regions, and it proves its worth year after year by producing heavily even when winter has been brutal.
Canadice earns its reputation as a multi-purpose grape. Eat the firm red fruits fresh as a snack, toss them into salads for a burst of spicy-sweet flavor, or press them into homemade juice and wine. The compact clusters and seedless nature make them particularly appealing for fresh eating straight from the vine, while the sweet, flavorful juice renders easily for home processing. Their ability to keep well on the vine through September extends your harvest window and lets you pick at peak ripeness.

Plant bare-root or containerized Canadice vines in early spring as soon as soil is workable, spacing them 8 feet apart. Choose a location in full sun to ensure robust growth and fruit quality. Prepare the planting site with well-draining soil rich in organic matter, and trellis or stake the vine for support as it establishes.
Canadice grapes ripen in mid-August and remain harvestable through September. Pick bunches when the grapes have turned a deep red color and feel firm and full on the vine; ripe berries will have a waxy bloom and slip easily from their stems. Cut clusters with pruning shears rather than pulling, as this preserves the vine and reduces damage to remaining fruit. The grapes keep exceptionally well on the vine, so you can pick selectively as you need them over several weeks.
Prune Canadice vines in late winter or early spring while dormant, removing old or damaged wood and training new growth along your chosen support structure. The variety produces compact clusters that benefit from moderate pruning to encourage air circulation and prevent disease. Remove any weak or crossing canes, and train the strongest shoots horizontally along your trellis system for even fruit distribution and easier harvesting.

“Canadice is a Cornell University licensed cultivar, developed through deliberate breeding that combined Vitis labrusca and vinifera genetics to create a grape suited to northern climates. The variety represents institutional plant breeding focused on solving the real problem faced by gardeners in zones 5 and 6: the need for seedless grapes that actually ripen in shorter growing seasons and survive harsh winters. By licensing this variety to nurseries, Cornell made cold-hardy, seedless grape growing accessible to home gardeners who had previously been limited to seeded or tender cultivars.”
