Ideally, chocolate should be wrapped first in foil and then in plastic and stored at a constant temperature of 65°F and 50% humidity. Slightly higher temperatures and humidity are acceptable although the chocolate may not last as long. Stored under perfect conditions, unsweetened and dark chocolate will last for 10 years, and certainly up to a year in good home kitchen conditions; milk and white chocolate for 7 to 8 months.

HERE IS WHAT HERSHEY HAS TO SAY:

Solid chocolate products will maintain their quality if well wrapped and stored in a cool, dry place (55-60°F). While refrigerated chocolate is certainly safe to use, we don’t recommend it. Chocolate kept in the refrigerator may "sweat" when brought to room temperature and may not melt properly.

Cocoa is considered a non-perishable item which should maintain quality if stored at room temperature in a tightly sealed container
