Don't know why I didn't think to take a gravity...
As for no visible activity, can anyone tell me what's going on with the yeast?
I was thinking that even during their aerobic metabolism of sugars, nutrients, etc. they would still be producing CO2, but apparently this isn't the case.
Thanks for the help/suggestions!
It's not that there's anything wrong with your yeast (obviously, now that you took a gravity) it's that your relience on an airlock is faulty.
If your airlock was bubbling and stopped---It doesn't mean fermentation has stopped.
If you airlock isn't bubbling, it doesn't mean your fermentation hasn't started....
If your airlock starts bubbling, it really doesn't matter.
If your airlock NEVER bubbles, it doesn't mean anything is wrong or right.
Your airlock is not a fermentation gauge, it is a VALVE to release excess co2. And the peak of fermentation has already wound down, so there's simply no need to vent off any excess co2. Or it is getting out elsewhere, which is nothing to worry about either.
The only answer that is accurate or consistant, are the numbers on the little stick. I have had every airlock bubbling/non bubbling/slow bubbling/fast bubbling/little krausen/big krausen/slow forming krausen/krausen staying 3 weeks after the hydro showed terminal gravity scenario imaginable in nearly 1,000 gallons of beer, and none of that stuff is as sccurate as 30 seconds with a hydrometer.
NOT go by airlocks, or size of krausen, or a calendar, the horoscope or the phases of the moon (those things in my mind are equally accurate).
Like I said here in my blog, which I encourage you to read, Think evaluation before action
you sure as HELL wouldn't want a doctor to start cutting on you unless he used the proper diagnostic instuments like x-rays first, right? You wouldn't want him to just take a look in your eyes briefly and say "I'm cutting into your chest first thing in the morning." You would want them to use the right diagnostic tools
before the slice and dice, right? You'd cry malpractice, I would hope, if they didn't say they were sending you for an MRI and other things before going in....
Thinking about "doing anything" like repitching, or bottling, or racking, without first taking a hydrometer reading is tantamount to the doctor deciding to cut you open without running any diagnostic tests....Taking one look at you and saying, "Yeah I'm going in." You would really want the doctor to use all means to properly diagnose what's going on?
And as you can see, there was absolutely nothing wrong with your yeasts at all.
