CSW CSW Wine Storage & Cellar Management

Question 1

What is the ideal temperature range for long-term wine storage?

Accepted Answer

45–65°F (7–18°C)

Answer

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?

Accepted Answer

To keep the natural cork moist and prevent it from drying out

Answer

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?

Accepted Answer

50–70%

Answer

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?

Accepted Answer

Excessive heat and temperature fluctuations

Answer

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?

Accepted Answer

The empty headspace between the wine's surface and the bottom of the cork

Answer

Increased ullage, or headspace, can indicate past leakage or evaporation and may signal that the wine has been compromised.
