Summary

Chenin Blanc is one of the world’s most versatile grape varieties, capable of producing the full spectrum of wine styles from bone-dry to lusciously sweet, and from still to sparkling. With approximately 32,000 hectares under cultivation globally, Chenin Blanc is most significant in the Loire Valley of France (where it produces Vouvray, Savennières, and Coteaux du Layon) and South Africa (where it is the most planted variety, known historically as Steen). The variety is characterized by exceptionally high natural acidity, which persists even at elevated sugar levels—enabling production of balanced sweet wines without cloying character. Chenin Blanc’s susceptibility to botrytis, when conditions are favorable, produces some of the world’s greatest dessert wines. Its neutral aromatic profile when young evolves into remarkable complexity with age, developing honey, lanolin, and quince characteristics.

Identity & Synonyms

Official Name: Chenin Blanc
VIVC Database: VIVC Entry #2525
Prime Name: CHENIN BLANC (VIVC)
Berry Color: BLANC (White/Green-yellow)

Synonyms:

  • Pineau de la Loire (Loire Valley - historical primary name)
  • Pineau d’Anjou (Anjou region, Loire)
  • Blanc d’Anjou (Loire)

Common Enological Issues

High Acidity Management

  • Cause: Chenin Blanc retains exceptionally high malic and tartaric acid even at elevated sugar levels; TA commonly 9-12 g/L in Loire.
  • Risk: Excessively tart dry wines in cool vintages; balance issues.
  • Decision point: MLF partial or complete can soften acidity for dry wines; residual sugar as balance mechanism; blending with lower-acid lots; stylistic acceptance of high-acid profile as varietal characteristic.

Botrytis as Dual Agent

  • Cause: High susceptibility to Botrytis cinerea; humid conditions determine whether it develops as beneficial noble rot or destructive grey rot. See Botrytis Management for comprehensive protocols.
  • Risk: Grey rot compromises fruit quality, introduces laccase, creates off-flavors; noble rot requires precise conditions.
  • Decision point: Selective hand-harvesting (multiple passes) essential for sweet wine production; weather monitoring; sorting to separate affected berries; laccase testing for grey rot detection.

Oxidation Susceptibility

  • Cause: Low phenolic content provides limited antioxidant protection; susceptible to both enzymatic and chemical oxidation. See Oxidation Management in White Wines for detailed protocols.
  • Risk: Premature browning; loss of freshness and fruit character.
  • Decision point: Protective winemaking (SO₂, inert gas, cool temperatures); minimize oxygen exposure; appropriate sulfur management at bottling.

Residual Sugar Stability

  • Cause: Off-dry and sweet wines contain fermentable sugar and potentially viable yeast.
  • Risk: Refermentation in bottle; carbonation in still wines; bottle explosions.
  • Decision point: Sterile filtration (0.45 μm); adequate sulfur dioxide; sorbic acid addition where permitted; cold storage.

Neutral Young Character

  • Cause: Young Chenin Blanc can be relatively neutral and unremarkable compared to aromatic varieties.
  • Risk: Consumer perception of low value; difficulty competing with aromatic varieties in commercial market.
  • Decision point: Oak treatment for complexity; lees contact for texture; extended aging before release; site selection for terroir expression; marketing emphasis on aging potential.

Esca and Trunk Disease

  • Cause: Fungal pathogens affecting vine trunk; Chenin Blanc shows moderate susceptibility.
  • Risk: Vine decline; yield loss; vineyard replanting costs; loss of old vines.
  • Decision point: Pruning wound protection; trunk renewal strategies; vineyard management practices.

Operational Considerations

Harvest timing:

  • Extremely variable depending on target wine style
  • Sparkling base: Early harvest (17-19 °Brix) for maximum acidity
  • Dry wines: Standard timing (20-22 °Brix) with emphasis on flavor development
  • Sweet wines: Extended hang time; multiple passes for botrytis-affected selection
  • Botrytis monitoring critical for sweet wine production

Sorting and selection:

  • Crucial for sweet wine production; separate clean, botrytized, and grey-rotted berries
  • Multiple harvest passes standard for quality sweet wines
  • Laccase testing for grey rot detection

Fermentation management:

  • Temperature: Cool (14-18°C) for aromatic preservation
  • Yeast selection: Neutral strains for terroir expression; aromatic strains for commercial wines
  • Fermentation arrest: Chilling, sterile filtration, or sulfur dioxide for sweet wines
  • Duration: Extended cool fermentation acceptable

MLF decisions:

  • Block MLF: Standard for sparkling, most dry, and all sweet wines; preserves characteristic acidity
  • Partial MLF: Some dry wine production for softer style
  • Full MLF: Rare; fundamentally alters varietal character

Oak program:

  • Traditional large neutral oak preserves fruit, adds texture
  • New oak (20-40%) for premium dry wines (Savennières style)
  • Sweet wines rarely see new oak; concentration sufficient
  • Duration: 6-18 months depending on style

Aging and development:

  • Chenin Blanc uniquely benefits from bottle aging
  • Even dry wines improve significantly over 5-10+ years
  • Sweet wines can age 50+ years
  • Sur lie aging (still or sparkling) adds complexity

Sparkling production:

  • Early harvest essential
  • Traditional method standard in Loire
  • Extended lees aging (18+ months) for quality cuvées
  • Dosage adjusted to balance high base acidity
