Most of the guides I gave seen make little distinction between the two.
I've bottle a litre of it for using as vinegar, started a new 5L brew with the new pellicle & 400ml of the scoby, a a 2L brew with just a few hunderd ml of scoby, and reserved the old pellicle & a few 100ml of scoby in the fridge for a later brew.
This time, I'll probably check the fermentation a bit sooner.
If it has vinegared, won't you transfer the vinegar bacteria to your next brew on the scoby?
