does soy milk have an expiration date like cow milk?

It lasts a lot longer than cow's milk - but if you buy it in those shelf-stable aseptic boxes, it will last for years.

Soy milk does have an expiration date like almost anything, but it lasts significantly longer. :)

Yes. I think everything has some sort of expiration date. But soy milk is a manufactured product, not a natural product. So its shelf life is longer than real milk.

Yes. The one that I have expires July 2012. It's printed on the box.
