I have a prime example of why not to use the airlock for fermentation indicator. I brewed my second batch last Saturday and by Wednesday the airlock had slowed significantly and the krausen had started to shrink and drop out. I checked the gravity on Thursday and it was nowhere near complete. I checked today and it is getting very close. There is very little to no activity in the airlock at this time. Bubbles every two to three minutes. TRUST YOUR HYDROMETER. Even though it is nearly complete I will hold it in primary at least five days past the third day of the SG reading going unchanged. being as I am a compliance engineer I love having a calibrated scale to work with.
