CSW CSW Wine Storage & Cellar Management 1 — Questions and Answers
Question 1: What is the ideal temperature range for long-term wine storage?
- 35–44°F (2–7°C)
- 45–65°F (7–18°C) (Correct answer)
- 66–75°F (19–24°C)
- 76–85°F (25–30°C)
Correct answer: 45–65°F (7–18°C)
The 45–65°F range allows wine to age slowly and gracefully without the risk of cooking or freezing.
Question 2: Why are wine bottles traditionally stored on their sides?
- To keep the natural cork moist and prevent it from drying out (Correct answer)
- To save shelf space in the cellar
- To allow the wine to cool faster
- To encourage sediment to collect at the bottom
Correct answer: To keep the natural cork moist and prevent it from drying out
Horizontal storage keeps wine in contact with the cork, preventing it from drying, shrinking, and allowing air ingress.
Question 3: What humidity level is considered optimal for a wine cellar?
- 10–30%
- 50–70% (Correct answer)
- 80–95%
- 100%
Correct answer: 50–70%
50–70% relative humidity keeps corks supple without promoting mold growth on labels and wooden racks.
Question 4: Which factor most commonly causes premature aging in stored wines?
- Consistent cool darkness
- Stable low humidity
- Excessive heat and temperature fluctuations (Correct answer)
- Storing bottles horizontally
Correct answer: Excessive heat and temperature fluctuations
Heat accelerates chemical reactions that age wine, and fluctuations cause expansion and contraction that can compromise the cork seal.
Question 5: What is 'ullage' in the context of wine storage?
- The adhesive used for bottle labels
- The empty headspace between the wine's surface and the bottom of the cork (Correct answer)
- The sediment that accumulates at the bottle's base
- The wax or foil capsule covering the cork
Correct answer: The empty headspace between the wine's surface and the bottom of the cork
Increased ullage, or headspace, can indicate past leakage or evaporation and may signal that the wine has been compromised.
Question 6: Which wine type generally benefits most from extended cellar aging?
- Beaujolais Nouveau
- Moscato d'Asti
- Grand Cru Bordeaux (Correct answer)
- Light unoaked Rosé
Correct answer: Grand Cru Bordeaux
Grand Cru Bordeaux has the tannin, acidity, and structural complexity to evolve and improve over decades of careful cellaring.
