I have been testing the commercial bean cellars in the freezer and have been noticing that the o-rings shrink with the low temperatures, basically, the cap shows movement when it comes right out of the freezer. I have 48 cellars and pretty much all of them show this behavior. Can you please advice? In a previous post you (Craig) said it was ok to use them in the freezer and that's the reason I bought them... Could it be defective o-rings?
