Does the parent Kombucha have to float before it forms a new one?
There is not much difference whether the Kombucha colonies float or sink. Its density is close to that of water or a little heavier, so when undisturbed, the gas out of fermentation will keep it afloat on or near the surface until someone disturbs it and releases the bubbles underneath, then it will sink. A new Kombucha will start on the surface whether or not the parent is floating or has sunk.
