I'm brewing my second batch in a continuous brewing system and have been having lack of fizz after the f2. One of the suggestions for fizz is to stir up the yeast before bottling, but with the continuous brew, you aren't supposed to touch the scoby at all. Stirring up the yeast certainly makes sense, because I used to do that when I did the gallon jar method and never had fizz issues, but is disturbing the scoby going to give me other problems with the continuous brewing?
