I don't know why this isn't posted in any of the topics here on whey or in any blog, etc., but HOW DO YOU KNOW whether your whey has gone bad? Right now this whey smells like a non-rotting dead animal, which is approximately the same as what whey smells like when it first comes out except that it's also "tangy" or smells like spoiled milk. In both cases, the smell is mild so that you can only smell it if you put your nose there. So what does whey smell and look like - whichever one changes if it's not both - when it is bad and will make you sick and not have probiotics?!
