What is the ideal wine storage temperature?
Long-term storage: 55°F (13°C) is ideal for all wine types. Short-term serving temperatures vary: Sparkling 40-50°F, White/Rosé 45-55°F, Red 55-65°F. Stability matters more than exact temperature - fluctuations of 5°F+ damage wine. Avoid temperatures above 70°F for extended periods - cooks wine, causes oxidation.
How much cooling capacity do I need for my wine cellar?
Calculate BTUs: 10 BTUs per bottle for passive cellars, 15 BTUs per bottle for active cooling in warm climates. Add 500 BTUs per square foot of room. Example: 500 bottles in 100 sq ft room = (500 × 15) + (100 × 500) = 7,500 + 50,000 = 57,500 BTUs. Use wine-specific cooling units, not regular AC.
Why is temperature stability important?
Temperature fluctuations cause wine to expand/contract, pushing corks out slightly and letting air in. This causes oxidation - wine tastes like sherry or vinegar. Consistent 55°F is better than swinging between 50-60°F. Daily fluctuations are worse than seasonal. Wine coolers maintain ±1°F stability, passive cellars may swing 5-10°F.
What humidity level should my wine cellar have?
Ideal humidity: 60-70%. Below 50%: corks dry out, air enters bottle. Above 80%: mold grows on labels and wood, though wine is fine. Passive cellars naturally maintain humidity. Active cooling removes humidity - may need humidifier. Cork condition matters more for long-term storage (5+ years).
