I think the labels say 8-10 months or so. Very conservative in my view. Please also note that I use this stuff only for baking, but I use a lot and buy it in bulk. I always repackage it at home (sealed zipper bags or heavier) and store then stash them in the freezers. Even at 2+ years beyond the formal expiration date, I've never encountered any off odors or tastes and it seems to be just fine. Just like most other staple goods, the most important part is the storage conditions. Truth be told, I'd never drink reconstituted skim milk as a beverage; I was forced to do so, if briefly as a child and it truly sucks! That 'economy' program lasted until one of us boldly challenged our frugal Mother, "We will drink it when you drink it." One mouthful and her experiment was over, but she never apologized for trying to poison us. For baking and cooking, it works just fine, but storage seems to be key. Best wishes.
