Why is my soy milk frozen?
I bought a quart of soy milk for the first time ever last week. It has been sitting unopened in the door of my refrigerator since. I pulled it out today to use it in a bowl of cereal and it was frozen solid.
My refrigerator is not particularly frigid; regular milk and juice products stored in the back do not freeze. It's even more shocking to me that it froze in the door of my fridge, since that is the warmest place.
Is this normal for soy milk? If not, what went wrong? How should I store soy milk?
*The expiration date is sometime in March 2011

Have you ever put a quart-sized container of plain water in the spot where your soymilk froze? Perhaps that spot in your fridge is actually very cold--not cold enough to freeze milk with all its fat content (even skim as some), but enough to freeze soymilk (especially if it's settled and separated a bit).

I've had the same thing happen - in fact, I've had a brand new soy milk freeze solid, sitting next to the other carton of soy milk that is around half full, which isn't frozen. Both the same brand and type of soy milk - one frozen solid, one not frozen at all. So I suspect that something may go wrong in some batches of soy milk that affects the freezing temp, but I have no idea what. Mine is Silk brand, organic unsweetened.
