That's according to food experts.
Food experts are advising people not to put chocolate in the fridge.
A survey by Galaxy, of 2,000 adults, found 78% store chocolate in the fridge.
18 degrees is reported to be the perfect temperature for chocolate to be both stored and eaten at.
Low temperatures, and high humidity levels in fridges, can cause sugar blooms, oxidation, and transform the taste and odour of the chocolate.
