Never heard of it and search says tea and sugar and SCOBY. All ready to drink brands show only tea and no juice. I think Malta Goya would be preferrable which is a ready to drink grain and sugar beverage. Probably not easy for DIY. Sort of like instant drink Postum which didn't do well here in USA and is not in stores now. Is SCOBY readily available? Is juice sub for tea?
So how I like to do it is make tea (black, green, it doesn't really matter), cool and sweeten it, then add a cup of your last batch of kombucha (or starter), put the scoby on top and let it ferment in a gallon jar with a cloth on top for a week. After a week, I fill smaller jars about 3/4 full, top it off with juice or fresh fruit, put lids on and let it ferment again for a couple days.
If you let it sit too long it'll get vinegary.
My mom used to make it alot, then this past year I started it up again. I've had good batches and not so good batches
