Question: do you need to refrigerate unopened soy milk?
Answer: While soy milk is unopened, proper storage depends on the kind of soy milk. If it's shelf-stable soy milk (sold unrefrigerated), then you should store it in a cool, dry place, e.g., in the pantry. ... If your soy milk was sold refrigerated, that's another story. It has to be kept in the fridge.
