Ideal Relative Humidity for Wine Cellars

The ideal relative humidity for wine cellars is generally between 50% to 70%.

What happens if humidity is too high?

While high humidity won't immediately ruin the wine, it will cause the labels on the bottles to peel, warp, and grow mold, ruining the aesthetic and resale value of the collection.

What happens if humidity is too low?

If a wine cellar drops below 50% relative humidity, the corks can dry out and shrink. This allows oxygen to seep into the bottle, prematurely oxidizing and ruining the wine.


Frequently Asked Questions

Does temperature matter as much as humidity for wine?
Yes, temperature is arguably more critical. Wine should ideally be stored at a consistent 55°F (13°C). Fluctuating temperatures can push the cork out or cook the wine.
How can I add humidity to a small wine fridge?
A simple and cost-effective method is to place a small sponge soaked in distilled water inside the fridge, checking and re-soaking it periodically.
