How Humidity Affects Wine Storage When people think about storing wine, temperature usually gets all the attention. But humidity plays an equally important role in protecting your collection. Humidity directly affects the cork, and the cork is what keeps oxygen out of the bottle. If the air is too dry, the cork can slowly shrink and dry out. Even tiny gaps allow oxygen to enter the bottle, causing the wine to oxidize prematurely. Oxidized wine often loses its fresh aromas and vibrant flavors, leaving it flat or tired long before it should be. On the other hand, excessive humidity can create problems as well. While the wine itself is generally protected, labels can become damaged, making bottles less attractive and potentially reducing their value for collectors. The ideal environment for wine storage is around 65% humidity. This level keeps corks healthy while preventing unnecessary moisture buildup. Maintaining that balance isn't easy in Southern California. Los Angeles is known for its dry climate, and indoor air conditioning can lower humidity even further. That's one reason many collectors choose professional wine storage instead of storing bottles at home. At Del Rey Wine Center, both temperature and humidity are carefully maintained year-round. Our climate-controlled facility provides the stable environment needed to protect every bottle, whether you're storing everyday favorites or rare collector wines. Proper humidity may not be something you notice every day, but over the course of years, it can make all the difference in how your wine ages.
