I use the 4 oz. mason jars (the smallest ones) for my cellar. I usually only buy a couple ounces of a blend at a time and cellar about a third of that in one of those small jars. They don't stack very well, but I also don't have the space or inclination to buy larger amounts of blends. I do have two wide mouth pint jars in use, one with 1Q and another that I combined leftover blends I didn't care for as a "display" jar alongside my antique cast iron cigar press.
