By carefully controlling humidity, active cellars prevent corks from drying out and minimize the risk of wine oxidation. This level of control is particularly beneficial in regions with low natural humidity or where precise humidity levels are required.
Ventilation
Active wine cellars often incorporate mechanical ventilation systems to ensure proper air circulation. This helps to reduce the risk of odors, mold, and mildew, as well as to maintain consistent air quality. The use of fans or air circulation systems aids in eliminating stagnant air and preventing any buildup of unwanted smells in the cellar. Active ventilation systems also provide the advantage of easy adjustment and control, allowing for quick air exchange when necessary.
Insulation
Insulation remains important in active wine cellars as it helps to minimize temperature fluctuations caused by external conditions. High-quality insulation materials are used to create a well-sealed environment, which prevents heat transfer or loss.
