Hm, I don't know the answer to that, but technically regular shortening is supposed to be good for 1 year after opening, if stored in a cool, dry place. I've had it go bad in under a year, which is why I followed CC suggestions to freeze my (more-expensive) hi-ratio as a precaution. I don't know if/how Hi-Ratio differs with regard to storage... Anyone?
