IBC Root Beer comes in 1 quart brown bottles, I get mine at Wal-Mart for about 70 cents. I use the clear cream soda bottles for distilled water. Also, check for a local beer-brewing store, one near me carries the usual 12 and 16 oz bottles as well as gallon jugs. A lot of hardware stores carry rubber stoppers in those little drawers with the small nuts & bolts.(posted 8272 days ago)
