How Long Does Cocoa Powder (Unsweetened) Last in Mylar Bags?
Quick Answer: Unsweetened cocoa powder lasts 10-15 years in mylar bags with oxygen absorbers and desiccant. Dutch-processed cocoa stores slightly longer than natural cocoa. Hot chocolate mix only lasts 2-3 years due to added dairy and sugar. Include desiccant — cocoa is highly hygroscopic.
