Enological Implications

Evidence-Backed Implications

Tempranillo dominance:

• ~80% of red grape plantings
• Moderate tannins; good acidity retention
• Excellent oak affinity (both American and French). See Oak Integration and Tannin Management for protocols.

Traditional American oak style:

• Historical use of American oak dominant
• Coconut, dill, vanilla aromatics
• Longer aging typical (18-36+ months). Extended aging requires volatile acidity monitoring.

French oak evolution:

• Modern producers increasingly use French oak
• Shorter aging periods
• More fruit-forward style

Operational Observations

Oak barrel economics:

• Aging requirements (1-2 years oak) require substantial barrel inventory
• American oak historically cheaper than French
• Barrel age management critical

Aging classification decisions:

• Same base wine can be designated Crianza, Reserva, or Gran Reserva
• Vintage quality influences classification allocation
• Economic implications of extended inventory holding

Frequent Compliance Risks

Aging Documentation

• Risk: Insufficient documentation of oak/bottle aging periods
• Impact: Cannot claim aging category
• Mitigation: Cellar tracking systems; barrel entry/exit logs

Oak Aging Shortfall

• Risk: Less than required oak aging (1 year Crianza, 2 years Gran Reserva)
• Impact: Must sell as lower classification
• Mitigation: Aging protocol management

Sub-Zone Labeling

• Risk: Claiming sub-zone (Rioja Alta, etc.) without 100% sourcing
• Impact: Labeling violation
• Mitigation: Grape origin documentation

Relevant Grape Varieties

• Tempranillo — dominant red variety (~80% of plantings)
• Grenache — secondary red variety (as Garnacha)
• Graciano — aromatic, acidity component
• Mazuelo/Carignan — color and structure component
• Viura — primary white variety
• Verdejo — recently authorized white
• Viognier — NOT permitted in Rioja

Related Appellations
