The shelf life of chocolate is generally a year. Ingredients such as nuts will shorten the shelf life. Chocolate kept beyond 1 year may suffer flavor loss or texture changes.
Can chocolate be frozen?
It is not recommended to freeze Filled Centered product, Lindor Truffles, and Liquid Filled Bars. However, other varieties can be frozen up to several months. Place the entire package into a sealed Freezer Bag. When ready to consume, allow the chocolate to slowly thaw by placing the bag in the refrigerator (6 hours). Once thawed in the refrigerator, slowly bring the product up to room temperature (2 hours, 65 F). Never re-freeze chocolate once it has thawed. Freezing chocolate can increase its shelf-life by 50%.
What is that white stuff on my chocolate?
Chocolate contains cocoa butter, a vegetable fat that is sensitive to heat and humidity. Temperatures above 75 degrees will cause chocolate to melt. The cocoa butter can rise to the surface and form a grayish discoloration called "cocoa butter bloom." Condensation on milk or semi-sweet chocolate may cause sugar to dissolve and rise to the surface as "sugar bloom." Neither "bloom" affects the quality or flavor of chocolate.
I freeze chocolates, too. But not white chocolate...tastes funny after being frozen...at least to me it does.
