Does Chocolate Spoil?
Sunday, December 10th, 2006Here’s a recent tidbit I found on the Scharffenberger FAQ page that asks that very question:
Q: Does your chocolate spoil?A: Eventually every food product will go past its prime. Dark chocolate, however, is one of the longest lasting and most stable foods you can buy. Our dark chocolate has a shelf life of approximately 18 months. If held properly, chocolate can last for years. That being said, many people wrongly identify the phenomenon of fat or sugar “bloom” as “spoiled” chocolate.
The best way to store a chocolate bar is in a cool, dry environment where it will not come in contact with heat or moisture. There is usually no need to refrigerate dark chocolate that you will use within 8 months to a year of purchase. If you live in a very hot or humid area and must refrigerate your chocolate, we suggest wrapping it tightly in an extra layer of plastic wrap to help protect the aroma and flavor. Always allow the refrigerated chocolate to warm to room temperature before eating. We suggest that you never freeze chocolate.
So what about that stuff that looks like mold? That white or grayish tint on it when it’s old?
Q: Why does chocolate sometimes get a white or gray sheen on it?A: There are two possibilities for this: 1) the cocoa butter has “bloomed” because the chocolate got warm enough for the cocoa butter’s crystalline bonds to break and re-form in a “sloppy” pattern (”fat bloom”); or 2) condensation of water on the chocolate’s surface has caused “sugar bloom”. Neither type of bloom damages the chocolate for cooking purposes, but both make the chocolate grainy for eating out-of-hand.
