Expiration & Storage Tips
When does dark chocolate cocoa powder expire?
In an unopened state, dark chocolate cocoa powder can last between 2-3 years past the 'best by' date on its packaging. It is a stable and dry substance making it much less prone to spoilage. However, once the packet is opened, its shelf life decreases to six months to a year. Always refer to the best before date to be fully certain. Cocoa powder can also be frozen to extend its shelf life up to 4-5 years. When defrosting, ensure to do it slowly, preferably in the refrigerator over several hours or even overnight to prevent the formation of moisture which may spoil it.
How do you tell if dark chocolate cocoa powder is bad?
If the cocoa powder appears very hard, caked, or lumpy, it might be a sign of moisture, which can lead to spoilage. A shift in color, from deep brown to a lighter shade, also indicates aging. Most notably, if you're seeing bugs or mold, or it smells off or stale instead of rich and chocolatey, discard it immediately.
Tips for storing dark chocolate cocoa powder to extend shelf life
• Store it in a cool, dry and dark place like a pantry, which is away from heat, moisture, and light sources.
• After opening, ensure the container is airtight every time you use it. Properly sealing it slows down the process of it reacting with oxygen, thus extending its shelf life.
• Consider transferring the powder into a glass or metal container if it came in a cardboard box, as these materials provide better protection.
• For long-term storage, freezing is a good option. Pack it in airtight containers or heavy-duty freezer bags to avoid freezer burn.
