hello!
you can find the 1 gallon large jars on e-bay. i spotted several for approx. $11. + shipping.

also i just drove down to santa barbara and set my son up with two 2 1/2 gallon Ceramic Water Crock Dispensers $18.95 + shippping. that can be found at foryourwater.com. ((what better health policy can you provide ??!!!) it is truly amazing the health benefits of this ancient tea brewing method!!

this container has a spigot and allows the continuous kombucha brewing method.

either way it is fun to brew.
i am on my 7th continuous batch and although i do not feel i have gotten it "RIGHT" as the tasty commercial brews,
we have been very happy with our results.
which vary...........but i consider this a self taught class so i am kind to myself.
but yes after completed and placing in airtight bottles (i use my cases of commercially made brew) and setting aside for 3-5 days the carbonation matches that of the commercially brewed kombucha teas!!!
be well and brew well! lisa rose
p.s. i have always used white vinegar as a disinfectant in my pots and brewing containers!
and ZERO molds have appeared!
and regarding fruitflies DO NOT USE cheese cloth EVEN if in many layers!! fruitflies can drop their eggs thru!! been there done that!!
