As stated above, everything was more than likely WELL before you moved the fermenter....had you taken a grav reading you would have known that.

You have a 50% perecent chance that the only reason the airlock is bubbling, is simply, because you moved the fermenter. Again, you can't equate fermentation with airlock bubbling. Airlocks often start or don't start or stop or start after a period for various reasons, including disturbing the fermenter. That doesn't mean the yeast are doing anything different that they were in the other room. Nor does it mean they aren't all it means is that co2 is coming out... But not why, or if fermentation is or isn't happening....

Dang should i not have moved the fermenter? That was last night and today it has started bubbling plus i was real careful when moving it. So i just thought i was gonna wing it without taking the final grav reading, i have just started brewing about a month ago and i honestly still havnt read the purpose or importance of doing this. Next thing on the to do list.

What you should have done, was to wait 72 hours, and take a hydrometer reading. And not care whether the airlock bubbles or not. Half my beers NEVER have a bubbling airlock, but I've never had a fermentation not happen before. Like I was quoted above.

Airlock bubbling and fermentation are not the same thing. You have to separate that from your mindset. Airlock bubbling can be a sign of fermentation, but not a good one, because the airlock will often blip or not blip for various other reasons...so it is a tenuous connection at best.

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. If it bubbles it is because it needs to, if it doesn't, it just means it doesn't need too...

Often an airlock will bubble if the fermenter has been disturbed in some way, like a change in temperature, change in atmospheric pressure, the cat brushing against it, opening it up to take a hydro reading, any number of things. The co2 has sat in stasis for a period of time, then it was disturbed so it is not longer at equilibrium with everything else now. And therefore it is blipping in your airlock...

Or you could indeed have fermentation happening, since maybe your fermentation was laggy and a change in temp restarted fermentation.

Airlock bubbling only tells you that co2 is coming out of the airlock, it is not telling you why. And there's various reasons. That's why it's not a good idea to equate airlock bubbling with fermentation...It could be because it is fermenting, or it could not be because of fermentation...so it's not a trustworthy tool.

And airlocks sometimes bubble or they don't. And airlock is a valve, a vent to release excess co2...NOT a fermentation gauge. It's important to make that distinction, or you'll be panicking everytime a an airlock doesn't bubble, or stops bubbling.

Fermentation is not always "dynamic," just because you don't SEE anything happening, doesn't mean that any-thing's wrong,, and also doesn't mean that the yeast are still not working diligently away, doing what they've been doing for over 4,000 years.

That's why you need to take a gravity reading to know how your fermentation is going, 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).

The most important tool you can use is a hydrometer. It's the only way you will truly know when your beer is ready...airlock bubbles and other things are faulty.

The only way to truly know what is going on in your fermenter is with your hydrometer. 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?

Next time just ignore the airlock and if you are concerned take a gravity reading.

Oh i see. Sorry If the noobness is aggravating. lol. Got it Next time. Gonna figure out how take the final gravity before the next brew day later this week ( i still havnt took it out of its tube). Thanks for helping me get a better understanding of this.

One of our members, Bobby M, has a decent video on how to use it.

Ignore the math, or use one of the calculators online or on brewing software.

The grav reading will tell you NOW where on the journey from Original gravity to terminal gravity, your beer really is. You have the OG, if you didn;t take one, the recipe still should tell you what the grav is for that recipe, in extract it is foolproof...Or you can enter the recipe into any beer calculator even the free ones found online.

Your recipe should also tell you what the FG should be..

.And your gravity reading will tell you what you beer is doing NOW.

When I added my yeast the hydro reading was at 1070. I figured that was because I had added 12 oz of honey to up the ABV. My temp was at 68.

I'm the Queen of Analogies around here, so I'll use one in this instance.

I wonder if you guys could tell me if my car needs gas? I drove quite a bit yesterday, and I a full tank yesterday. I could check the gas gauge, but I didn't. I don't really want to learn how to do something that basic. Should I put more gas in it?

Well, the question is sort of the same. Without knowing your "gauge" of fermentation (the specific gravity), we just can't tell you what to do. If the SG isn't moving after three days, then you need more yeast. It's more than likely that fermentation has occurred, though.

Moving a fermenter can cause airlock bubbling. So can temperature change, and so can fermentation. The lack of bubbling doesn't mean anything, though.
