Vermont’s extreme winters demand grape varieties with exceptional cold hardiness, such as Valiant. When you’re searching for the best grapes to grow in vermont, you need varieties that can survive -30°F and still produce a decent crop.
Cold climate viticulture is different from growing grapes in California or New York. You face short growing seasons, late spring frosts, and deep freezes that kill tender vines. But don’t worry—many excellent grapes thrive here.
This guide covers the top varieties for Vermont home growers and small vineyards. You’ll learn which grapes handle cold, resist disease, and actually taste good.
Best Grapes To Grow In Vermont
These are the most reliable grape varieties for Vermont’s climate. Each one has proven cold hardiness and reasonable disease resistance.
Valiant Grapes
Valiant is the gold standard for extreme cold. This variety survives -50°F without damage. It ripens early, usually by mid-September.
Valiant produces small, blue-black grapes with a foxy flavor. They work well for juice, jelly, and blending. The vines grow vigorously and need strong trellising.
- Cold hardiness: -50°F
- Ripening: Early September
- Use: Juice, jelly, wine blending
- Disease resistance: Good
Frontenac Grapes
Frontenac is a popular red wine grape for cold climates. It survives -35°F and produces deep red wines with cherry notes. The grapes are small but packed with flavor.
This variety needs full sun and good air flow. It resists powdery mildew better than many hybrids. Harvest in late September to early October.
- Cold hardiness: -35°F
- Ripening: Late September
- Use: Red wine, rosé
- Disease resistance: Moderate to good
Marquette Grapes
Marquette is the top choice for serious Vermont winemakers. It combines cold hardiness (-35°F) with excellent wine quality. The flavor profile includes cherry, berry, and spice notes.
Marquette ripens earlier than Frontenac, usually by mid-September. It needs careful pruning to avoid overcropping. The vines are moderately vigorous.

- Ripening: Mid-September
- Use: Red wine
- Disease resistance: Good
La Crescent Grapes
La Crescent is a white wine grape with apricot and citrus aromas. It survives -35°F and ripens in early October. This variety makes excellent dry and sweet wines.
La Crescent can be prone to powdery mildew in humid summers. Plant in a sunny, well-ventilated spot. The grapes have thick skins that resist splitting.
- Cold hardiness: -35°F
- Ripening: Early October
- Use: White wine
- Disease resistance: Moderate
St. Croix Grapes
St. Croix is a versatile red grape for juice and wine. It survives -30°F and produces mild, fruity wines. The vines are productive and disease-resistant.
This variety does well in Vermont’s heavier soils. It ripens in late September. St. Croix is a good choice for beginners.

- Ripening: Late September
- Use: Juice, wine
- Disease resistance: Good
Swenson Red Grapes
Swenson Red is a table grape with excellent flavor. It survives -30°F and ripens in early September. The berries are large, red, and sweet.
This variety is perfect for fresh eating. It also makes good juice. Swenson Red needs regular pruning to maintain fruit quality.
- Cold hardiness: -30°F
- Ripening: Early September
- Use: Fresh eating, juice
- Disease resistance: Moderate
Site Selection And Preparation
Choosing the right spot is critical for grape success in Vermont. Even the hardiest varieties struggle in poor locations.
Sunlight Requirements
Grapes need full sun—at least 6-8 hours daily. South-facing slopes are ideal. They warm up faster in spring and stay warmer in fall.
Avoid shaded areas near buildings or trees. Shade reduces fruit quality and increases disease risk.
Soil Conditions
Grapes prefer well-drained soil with pH between 5.5 and 6.5. Heavy clay soils can cause root rot in wet years.
Test your soil before planting. Add lime to raise pH or sulfur to lower it. Organic matter helps drainage in heavy soils.
Air Drainage
Cold air settles in low spots, causing frost damage. Plant on slopes where cold air drains away. Avoid valley bottoms and frost pockets.
Good air flow also reduces fungal diseases. Space vines properly and keep the area weed-free.
Planting And Care
Proper planting sets your vines up for success. Follow these steps for healthy growth.
When To Plant
Plant in spring after the last frost. In Vermont, that’s usually mid-May to early June. Bare-root vines should be planted as soon as the soil is workable.
Fall planting is risky in Vermont. Young vines may not establish before winter.
Spacing And Trellising
Space vines 6-8 feet apart in rows 8-10 feet apart. This allows room for growth and air circulation.
Use a sturdy trellis system. The high cordon or Geneva double curtain work well for cold climates. Set posts deeply—frost heave can topple weak trellises.
Watering And Mulching
Water young vines regularly during their first year. Established vines are drought-tolerant but benefit from deep watering during dry spells.
Mulch with wood chips or straw to retain moisture and suppress weeds. Keep mulch away from the trunk to prevent rot.
Pruning
Prune in late winter or early spring before buds swell. Remove dead, damaged, or crossing wood. Leave 2-3 bud spurs for fruiting.
Severe pruning is better than light pruning for cold-climate grapes. It reduces the crop load and improves fruit quality.
Winter Protection
Even hardy varieties need some winter care in Vermont. Here’s how to protect your vines.
Mulching For Winter
Apply a thick layer of mulch (6-8 inches) around the base after the ground freezes. This insulates roots from temperature swings.
Remove mulch in spring when danger of hard frost passes.
Burying Vines
For extra protection, bury canes in soil or compost. This method works well for less hardy varieties.
Dig a trench next to the vine, lay the cane in it, and cover with 6 inches of soil. Uncover in spring.
Using Row Covers
Floating row covers provide 4-6 degrees of frost protection. Use them in spring to protect buds from late frosts.
Remove covers during the day if temperatures rise above 50°F.
Pest And Disease Management
Vermont’s humid summers create ideal conditions for fungal diseases. Stay ahead of problems with these strategies.
Common Diseases
Powdery mildew and downy mildew are the biggest threats. Black rot and botrytis also cause problems in wet years.
Choose resistant varieties when possible. Marquette and Frontenac have good resistance. La Crescent needs more attention.
Prevention Tips
- Space vines for air circulation
- Prune to open the canopy
- Remove fallen leaves and fruit
- Apply sulfur or copper sprays preventatively
- Water at the base, not on leaves
Pest Control
Birds love ripe grapes. Use netting to protect your crop. Deer can damage vines—fencing may be necessary.
Japanese beetles sometimes appear in July. Hand-pick them or use insecticidal soap.
Harvesting And Using Your Grapes
Knowing when to harvest is key to getting the best flavor. Here’s what to look for.
When To Harvest
Grapes ripen from late August to October, depending on variety. Taste test regularly—color alone isn’t reliable.
Look for full color, slight softness, and sweet flavor. Seeds should be brown, not green.
How To Harvest
Cut clusters with clean pruners. Handle gently to avoid bruising. Place in shallow containers to prevent crushing.
Harvest in the morning when grapes are cool. Refrigerate immediately if not processing right away.

These varieties have the complexity and structure needed for serious winemaking.
Best For Juice And Jelly
Valiant is the top choice for juice and jelly. It has intense flavor and high sugar content. St. Croix also works well.
These varieties are easier to grow and more forgiving than wine grapes.
