I have some liquid malt extract from Northern brewer that is about 2 years old. It was in the fridge the whole time and was the fresh kind that they pack in the plastic milk style jugs. Is it possible that it is still useable? Is there any easy way to tell if it is not usable? There is no bulging of the containers. I know that it won't be optimal, but I hate the ideal of throwing it away if I
can still turn out a relatively drinkable beer out of it.
