What is the ideal temperature and humidity for a wine cellar?

Most wines are best stored at a consistent temperature between 55°F and 58°F, with relative humidity maintained between 50% and 70%. Temperature fluctuations are one of the most damaging factors for wine—even small swings over time can accelerate aging, compromise corks, and alter a wine's flavor profile. Humidity that is too low can dry out corks and allow air into the bottle, while excessive humidity can promote mold growth. A properly engineered wine cellar cooling system eliminates these variables by maintaining stable conditions year-round, regardless of the outside climate or season.

What is the difference between a self-contained and a split wine cellar cooling system?

A self-contained cooling unit houses all components—compressor, condenser, and evaporator—in a single unit that is typically mounted through the wall of the cellar. These units are simpler to install and work well for smaller cellars with adequate ventilation outside the unit. A split system separates the evaporator inside the cellar from the condenser, which is located outside or in a remote mechanical space. Split systems are quieter, handle larger spaces more effectively, and are often the preferred choice for high-end residential and commercial wine cellars where noise and aesthetic integration matter. Our team will recommend the right system based on your cellar size, location, and goals. Call us at (831) 287-8808 .
