Enological Implications

Evidence-Backed Implications

Sangiovese dominance requirement (80%+):

• High natural acidity of Sangiovese requires management. See pH and Acidity Adjustment for principles.
• Complete MLF standard practice
• Blending with softer varieties (Merlot, Colorino) affects final balance

Gran Selezione estate requirement:

• Must use only estate-grown grapes
• Limits blending options to owned/controlled vineyards
• Positions as single-estate quality tier

Operational Observations

Tiered production planning:

• Same vineyard source can produce Annata, Riserva, or Gran Selezione
• Selection decision impacts cellar allocation and aging program
• Cash flow varies significantly by tier (12 vs. 30 months)

Oak program flexibility:

• No minimum oak aging specified for Annata or Riserva
• Allows range from no-oak to heavily oaked styles
• Producer philosophy determines approach

Frequent Compliance Risks

Sangiovese Minimum Shortfall

• Risk: Blend falling below 80% Sangiovese
• Impact: Cannot be labeled Chianti Classico
• Mitigation: Precise blending records; component tracking

Gran Selezione Sourcing Violations

• Risk: Using purchased grapes for Gran Selezione
• Impact: Declassification to Riserva or Annata
• Mitigation: Vineyard ownership/lease documentation

White Grape Inclusion

• Risk: Historical practice of including white grapes (Trebbiano, Malvasia)
• Impact: Not permitted under current disciplinare
• Mitigation: Vineyard audit; separate harvesting

Relevant Grape Varieties

• Sangiovese — primary variety (80-100%)
• Canaiolo Nero — permitted complementary
• Colorino — permitted complementary
• Cabernet Sauvignon — permitted complementary
• Merlot — permitted complementary
