Q1. Describe your experience with fermentation management, specifically regarding temperature control and yeast selection for different varietals.
Why you'll be asked this: This question assesses your technical depth in a core winemaking process, your understanding of varietal-specific needs, and your ability to make critical decisions that impact wine quality.
Discuss specific varietals (e.g., Pinot Noir vs. Chardonnay), detailing temperature regimes, yeast strains used (e.g., Lalvin, Scott Labs), and how these choices impact aromatic profiles, mouthfeel, and overall wine style. Quantify results where possible (e.g., 'achieved desired volatile acidity levels consistently').
- Generic answers without specific examples of varietals or yeast types.
- Lack of understanding of how fermentation parameters influence wine characteristics.
- Inability to explain troubleshooting steps for stuck or problematic fermentations.
- How do you monitor fermentation progress, and what corrective actions do you take if issues arise?
- Can you discuss your experience with malolactic fermentation and control strategies?
- What specific equipment or software do you use for fermentation monitoring and control?
