Kombucha brew flavorings

I'm getting pretty good at this kombucha brewing.   My last batch was ready in about 3 days, which I was shocked since it usually takes about a week for a batch to get to the right consistency.  I made my satellite batch, honey basil ginger.  I also had enough to bottle 3 liter sized bottles.  New flavors are black cherry basil, cranberry basil, and blueberry basil.    The cherry one was enjoyed tonight with our spaghetti squash spaghetti dinner.

Even though I have a continuous brew going, I think I am going to clean out the bottom of my jar before fermenting the next batch.    Need to do a little research beforehand.
