No, dual zone wine refrigerators aren't always better than single zone wine fridges. Both have different, unique purposes. If you are a wine collector or enjoy the taste of all types of wines, then a dual zone wine cooler will provide you with ample space to store both your reds and whites. If you only enjoy a single type of wine and want to age them or store them for longer periods of time, then a single zone cooler would be a far better choice.
