You can cram quite a bit into mason jars. Flakes are also another obvious choice for effeciency sake. I have 20 lbs cellared now, 99% of which is in jars, and it can get kind of expensive to buy jars. if I were to do it over again, I'd just cellar everything in quart jars. Now I only put the stuff prone to age really, really well long term in 8 ounce jars, since I don't need to interrupt aging for more than a few ounces. Everything else is going in quart jars.
