Maybe it's trying to tell you to buy American grain!
I have those issues with inscrutable Thai Jasmine rice bags. There was an episode of Dirty Jobs where he was instructed on how to open the bags of Soy Beans. They don't show it close up enough for me to truly see the trick.
There is a guy who works with me who can do it with some regularity, I'll try and film him doing it, even though I don't think he knows what he's doing.
