Chocolate and Other Cocoa Products
Chocolate will keep for up to a year at a temperature of 18°C to 20°C (64°F to 68°F) with a relative humidity level of 60%. These are the ideal storage conditions. It is not always possible in bakeries to meet the ideal, but in general, room temperature is all right. Chocolate must be kept safe from odours and humidity, and therefore the refrigerator is not the ideal place to store it.
These guidelines apply also to all pure chocolate products, such as chocolate chips, hail, and sticks. All must be protected from humidity and odours and kept cool and dry at room temperature in sealed containers or in the original packaging.
