This is what got me into homebrewing, fermenting cabbage,kefir,kombucha. I just use my bottle capper and used 16 oz pint beer bottles. I usually use dried fruit/or a small amout of fruit juice.Then cap them check one after 5 days,but usually keep them till 7 before refrigerating.
Sounds like you should just get a bigger jar, get a gallon or two depending how much you drink it. I rotate usually ferment about1.5- 2 wks bottle one week usually getting 6 pints. I ordered my scoby on line and have been making kombucha about a year.
I recommend ginger to bottle with along with your favorite fruit.I like the spicy kick ginger gives and makes it even better for you.
