Okay leave the top off the whole time? I just want to make sure I am reading this right since I want to do this. Thanks.Probably do...some of the Bragg's I've seen just has a little smokey swirl in the middle which you will miss if you aren't looking closely. The mother comes in all consistencies, depending on the way it was developed and what food it currently has to feed on. That sediment in the bottom is just that...but the whole bottle will have yeast spores in it if they advertise it as such. Here's a good way to find out....place some in a plain bottle of ACV, leave the top open to air, place in a dark cupboard and check on it in a week or so.
When you raise it up and look through the liquid after that time, you should see a whitish looking swirly of mother in it.
