Protect your investment.
If you don’t have a wine storage space that’s consistently cool, dark, and moist, a wine refrigerator–cooler is a good idea.
Unlike a standard refrigerator, which keeps your food very cold and dry, a wine fridge keeps wine between 10-15˚C (50-60˚F) and at the proper humidity.
Keeping your wine in a separate wine fridge also helps prevent cross-contamination from food odors. If cost is a concern, remember: wine can be an investment, and in that case a good wine fridge is a way to protect your investment.
