Pomerol Clone Grape

Vitis vinifera 'Pomerol Clone'

vine

Pomerol Clone is a premium wine grape variety originating from the Pomerol region of Bordeaux, France, known for producing rich, full-bodied red wines with notes of dark fruit and earthiness. This clone represents a specific genetic selection optimized for quality wine production in cool to moderate climates. It is a vinifera variety that requires careful management and is best suited for dedicated vineyard cultivation.

Growing Conditions

☀️
Sun: Full sun, 7-8 hours daily minimum; ideally 8+ hours for proper ripening
💧
Water: Moderate watering during growing season; establish deep root system through strategic watering. Reduce water as grapes mature to concentrate sugars. Approximately 20-24 inches of water annually depending on climate.
📏
Spacing: 48 inches
📅
Days to maturity: 120-150 days from bloom to harvest (varies by climate and management)
🌱
Planting depth: Plant dormant cuttings or rooted vines at soil level; graft union should be 2-3 inches above ground to prevent disease

Soil

Type: Well-draining, gravelly or sandy loam soil with moderate fertility
pH: 6.0-7.0
Amendments:
Aged compost Perlite or gravel for drainage Minimal nitrogen fertilizer (excessive vigor reduces wine quality) Potassium and phosphorus for ripening

Growth Stages

1

Dormancy & Budbreak

6-8 weeks (March-April in Northern Hemisphere)

Canes are woody and bare; buds swell and break in spring releasing tender new shoots with small leaves

Prune during dormancy (winter) to 2-3 buds per cane for mature vines. Protect buds from late frosts. Remove winter-damaged wood.

2

Vegetative Growth

8-10 weeks

Vigorous shoot growth with developing leaves, tendrils, and lateral shoots. Canopy expands rapidly.

Manage canopy to prevent overcrowding; remove excessive laterals and weak shoots. Provide support structure (trellis/wire system). Begin training shoots along supports. Monitor for powdery mildew.

3

Flowering & Fruit Set

3-4 weeks

Inconspicuous small green flowers appear at nodes; flowers are self-fertile and wind-pollinated. Berries set and begin expanding.

Avoid excessive watering during flowering; maintain consistent moisture. Continue canopy management to ensure airflow. Do not apply sulfur during flowering. Thin clusters if yield is excessive (leave 2-3 clusters per shoot for premium wine).

4

Veraison & Ripening

4-6 weeks

Grapes change color (red varieties turn from green to deep purple-red), soften, and accumulate sugars, tannins, and phenolic compounds. Canopy leaves may show autumn colors.

Reduce water stress to concentrate flavors (regulated deficit irrigation). Continue canopy management for sunlight exposure. Monitor brix (sugar content) and phenolic ripeness. Reduce nitrogen fertilizer; provide adequate potassium.

5

Harvest & Post-Harvest

Harvest window 2-3 weeks

Grapes reach optimal ripeness with concentrated sugars and balanced acidity. Berries are plump and dark purple-red with waxy bloom.

Harvest at optimal brix (typically 23-25 for this clone). Hand-harvest to prevent berry damage if producing wine. Prune off excess canopy after harvest to prepare for dormancy. Remove and dispose of diseased fruit.

Companion Planting

Plant with:

Avoid planting near:

Brassicas (cabbage, broccoli) Fennel Rue Horses (not plants, but important) Areas with poor drainage

Common Pests

  • Improve air circulation through canopy management; apply sulfur fungicide (not during flowering); remove affected leaves and shoots; maintain consistent irrigation

  • Copper-based fungicides; improve drainage and airflow; remove infected leaves; apply preventative sprays in humid conditions

  • Use grafted vines on phylloxera-resistant rootstocks (essential in most regions); inspect nursery stock carefully; avoid replanting with own-rooted vines in infested soil

  • Hand-pick early morning; use pheromone traps away from vines; apply neem oil or spinosad; encourage natural predators

  • Reflective mulches; insecticidal soap; encourage beneficial insects; avoid broad-spectrum pesticides that kill predators

  • Remove infected berries and mummified fruit; improve air circulation; apply fungicides; prune for canopy management

Uses

🍳

Premium Wine Production

Culinary

Pomerol Clone is exclusively used for fine wine production, creating full-bodied red wines with complex flavors of dark fruits, plums, and earthy undertones. This clone is prized for producing wines with excellent aging potential and silky tannin structure. [source]

🎨

Home Winemaking

Craft

For dedicated home winemakers, this clone allows production of craft wines that rival commercial Pomerol-style wines when proper fermentation and barrel aging techniques are employed. [source]

🏠

Landscape Ornament

Household

Beyond wine production, the grapevine serves as an attractive ornamental with deeply lobed foliage, providing shade on pergolas or arbors while producing fruit. [source]

🦋

Wildlife Food Source

Wildlife

Ripe grapes provide valuable nutrition for birds and beneficial insects, supporting local ecosystems while any excess fruit can be left for wildlife. [source]

Harvest Tips

Harvest grapes in late September to early October (Northern Hemisphere) when brix reaches 23-25° (optimal for this clone). Taste grapes for phenolic ripeness (seeds should be brown, not green). Hand-harvest clusters using pruning shears to avoid crushing berries if making wine. For highest quality, harvest in early morning when temperatures are cool. Bring to winery/processing facility promptly to preserve aromatic compounds.

Fun Facts

  • 🌱 Pomerol Clone grapes produce some of the most expensive wines in the world; a single bottle of vintage Pomerol can exceed $1,000 due to limited production and exceptional aging potential.
  • 🌱 The term 'clone' in viticulture refers to a genetically identical propagation from a single parent vine, meaning all Pomerol Clone vines descend from a single exceptional ancestral plant in Bordeaux.
  • 🌱 Unlike most fruit crops, premium wine grape quality typically improves when vines are moderately stressed by limiting water and nitrogen; this stress concentrates flavors and tannins rather than promoting excessive vegetative growth.
