What the sources say

FoodKeeper has one entry for cocoa and cocoa mixes: an unopened package keeps indefinitely in the pantry, and an opened one 1 year in the pantry.1

Iowa State University Extension agrees that unopened unsweetened cocoa powder has an indefinite shelf life, but gives opened cocoa powder a longer window, best quality for 3 years after opening, provided it is stored properly in tight packaging.21

It says the same holds for Dutch-process cocoa.2

The reason it gives is that the powder contains no fat or additives, although cocoa may lose its potency.2

The NDSU Extension food storage guide lists cocoa mixes on a separate line, at 1 year in the cupboard, with the advice to cover them tightly.3

FoodKeeper gives no refrigerator or freezer time for cocoa.1

In an article on natural and Dutch-processed cocoa, Iowa State University Extension also describes cocoa products as unsweetened and gluten-free, with a long shelf life.4
