Ideal wine storage temperature is 55–58°F with humidity at 55–70%, held steady year-round. The key is consistency — large swings in temperature or humidity damage corks, allow oxidation, and accelerate aging. A properly designed wine room with a sealed envelope and dedicated cooling unit holds those numbers without drifting.
How to maintain the target conditions
- Use a wine-room-rated cooling unit (split, ducted, or through-wall)
- Insulate and vapor-seal the room envelope
- Install solid-core, gasketed door
- Add humidity control if your climate is dry
- Use a quality temperature/humidity sensor with alerts
We design, install, and service wine rooms through wine-room cooling, plus pair with humidifiers and insulation as needed.
