I have been brewing my Kombucha on a Continuous Brew for several months. I typically draw out the brewed Kombucha every 14 - 18 days, and then let it sit bottled on the counter for 3-5 days.
I have tried adding flavoring (organic grape juice, slices of raw ginger etc) to the 2nd fermentation but still no fizz!
I use e-z cap bottles (that I bought at a beer supply store).
I have made Kombucha with Black Tea, and other times with Green Tea.
I use a 1 cup of Tea & 1 tablespoon of sugar ratio when I replenish the continuous brew after I have drawn out the KT.
The continuous brew kombucha container is left on the kitchen counter covered with a tablecloth and secured with a rubber band...and I draw out the KT through a spigot.
My SCOBY grows beautifully every time, so I know it is alive....but no fizz
