Grapes, White 'Vignoles' (Live Plant)

Key Characteristics

• Origin: 'Vignoles' is a white hybrid grape variety once believed to be of a grapevine that was imported into the US in 1949 named Ravat 51, but later genetic testing revealed that the specimen could not have either Seibel 6905 nor Pinot de Corton, the parents of Ravat 51, could be a parent to the vine. It gained popularity in North America, particularly in regions like New York and Missouri, and was officially named 'Vignoles' in 1970 by the Finger Lakes Wine Growers Association.
• Patent Status: Based on its release date, 'Vignoles' grapes are **not patented** and are considered a public domain variety.
• Berry Production: Produces small, oblate (flattened round) berries that are often contorted due to the compactness of the clusters. The berries have a thick, light green skin with a pinkish tinge and juicy flesh. They are known for developing high sugar levels while retaining high acidity. Clusters are small and very compact, occasionally with a small wing.
• Ripening Time: Ripens in the **mid-season** to **late season**, typically from late August to mid-September in many growing regions. Bud break is late, which helps it avoid damage from late spring frosts. It takes approximately 105 days from bloom to harvest.
• Plant Size and Appearance: The 'Vignoles' vine is moderately vigorous with an upright and open growth habit. It requires a support system like a trellis.
• Flowers: Produces typical, inconspicuous grapevine flowers in the spring.
• Hardiness: Considered moderately hardy, generally within USDA Zones **5 through 7**, with some reports of tolerance in Zone 4 and potentially Zone 8 with protection. It can withstand temperatures down to -10°F to -15°F.
• Pollination: 'Vignoles' is self-fertile and does not require another grape variety for pollination.
• Growing Conditions:
  • Sunlight: Requires full sun for optimal ripening and flavor development.
  • Soil: Prefers deep, loamy, medium moisture, and well-drained soils. Good drainage is essential.
  • Watering: Requires consistent moisture, especially during the growing season.
  • Fertilizing: Follow general recommendations for grape fertilization in your region.
  • Pruning: Requires regular pruning during the dormant season to manage growth and maximize fruit production.
• Uses: Primarily used for **wine production**, 'Vignoles' is highly versatile and can produce various styles:
  • Excellent **late-harvest sweet wines**, including ice wine, due to its ability to retain high acidity alongside high sugar levels.
  • Fruity **dry and off-dry white wines** with notable aromatics and balanced acidity.
  • Semi-sweet wines with pronounced floral and tropical fruit notes (apricots, pineapples).
• Wildlife Value: Grapevines can provide food and shelter for wildlife. Birds may be attracted to the ripening grapes.
• Ornamental Value: Grapevines can be attractive when trained on structures.
• Disease and Pest Resistance: 'Vignoles' is rated as highly susceptible to **Botrytis bunch rot** and **powdery mildew**, and susceptible to Anthracnose. It has moderate susceptibility to crown gall and downy mildew. Good vineyard management practices, including adequate airflow and timely spraying, are crucial.
