Climate Control: Why are Temperature & Humidity Important?

When we design wine cellars, cooling systems often come up in our discussion. We can use cooling equipment to manage the temperature when storing wine. Proper storage with a suitable cooling system to maintain optimal temperature and humidity levels is required to keep wines fresh over time.

But what are those levels? And why are temperature and humidity so critical to storing wine?

Why is Temperature Important?

When discussing how temperature factors into wine storage, it is important to realize we need to consider the temperature inside and outside the wine cellar. Outside ambient temperature in hot climates could indicate the need for a more extensive cooling system to maintain the environment effectively.

Units that aren’t adequate enough can lose control of the humidity in turn. This is part of the reason it’s so essential to design the right system.

The ideal temperature you should keep in your wine cellar is between 12 °C - 14 °C. Ensure that the temperature remains constant and that no wild fluctuations are occurring. Temperature fluctuations can cause the cork to expand and contract, seriously affecting its ability to age and store properly.

Why is Humidity Important?

Humidity can wreak havoc and destroy the look of the bottles themselves. Too much humidity can cause labels to deteriorate and become illegible. The quality of the wine can be affected as well as the cork can dry and crack under little humidity and oxidize the wine.

Controlling the humidity level in your wine cellar starts with having a properly constructed and sealed space. Cooling systems are crucial in hot and cold climates to help ward off issues due to humidity.

Humidity levels are indicated by the relative humidity (RH) percentage in the space. Simply put, ideally, you want to keep your RH levels between 55%-75% and NEVER below 50%.

Keep track of the RH in your space to ensure your wine ages well, keeps corks from drying, and maintains the label's quality.

Each design comes with its challenges, and each home has its obstacles. We have several different cooling systems to suit the needs of your wine cellar and your home!
