Yikes, people. Forget the airlock. Sometimes it helps, sometimes it doesn't. But it is fun to watch.

Just go get a carboy or Better Bottle and WATCH the fermentation. You'll know when it's done by looking at it. Now everybody make nice.

I put the wort in the fermenter, pitch the yeast, and watch to see that some activity has started thru the airlock after a few hours or the next day.

After a month or 6 weeks or whatever, I give it a swirl and come back two days later, get a FG reading to document the beer and find ABV, and rack it into a keg.

There are so many things that can make an airlock appear to be not active, and things that can make a finished ferment look active, by the airlock.

It means nothing either way, and only serves as a passive check valve for gas coming out and nasties to not go in.

A hydrometer or refractometer is the only way to know what the current state of the beer is.

So what, Revvy can be a little abrasive sometimes. Its not that big of a deal, get over it. Revvy has probably helped more noob brewers than 99% of the members in this community. Although sometimes he and I have had misunderstandings and exchanged words I always remember that they are just that, words. I respect Revvy for his contribution to HBT and consider him a very valuable asset. He never claimed to be a scientist and will be the first to admit that, but what he does have is experience. And sometimes experience is worth more than knowledge.

As far as airlocks are concerned I've had krausen drop and airlock activity stop but the gravity continued to drop. Towards the latter end of fermentation you'd have to sit around the airlock and wait for spurts of gas every hour or so. A hydrometer/refractometer will tell you the gravity, gas coming from the carboy won't. There is much more to be learned from using precise instruments than there is from using a fifty cent piece of plastic.

I am totally with you on this. Revvy has gone above and beyond to help the beginners who come to this forum. All this banter aside, that's something that gets my respect. Had my share of homebrew last night and mellowed out. Hope we can all start this new day as friends.

It was a rough game, but thanks for playing.

I have to disagree with this statement.. excessive sampling is excessive reasoning to taste excessive samples.. especially for those of us who are inherently impatient at heart...so you can't say it does *nothing*...

just a thought...

There is a non-zero chance that even your hydrometer/refractometer doesn't tell you what the current state of the beer is (just use your imagination...you can come up with ways it could be wrong). I admit...it's very close to zero but still non-zero.

On the other hand I think that using the airlock, along with experience and knowledge of what has already happened (like; krausen rose and fell) gives me a very, very good idea of where the beer is at in the process. There's a non-zero chance it would be wrong...but still very close to zero. I'm fine with that very small risk...it's just a tiny bit more risk than relying on a hydrometer imo. It's not like I'm waiting for the airlock to stop so I can rack it...I'm not racking it before 2 weeks no matter what. Usually the airlock has been idle for at least a week. At that point I see no reason to take a hydro sample...I'll just catch a hydro sample as I'm racking (by 'catch' I mean the sample gets collected as I'm racking so no chance of contamination). However, if the airlock was still bubbling a lot I wouldn't rack it...or take a hydro sample.

I know that in the past Revvy has claimed to have full fermentations without ANY bubbles coming from an airlock. I think that claims like that, without further clarification, can be misleading. It seems like a gross exaggeration just to try to make a point (and I totally agree that Revvy is usually one of the more helpful HBT members). If your beer fully fermented...it made CO2...a LOT of it...fact. If you had a full fermentation without airlock activity you either had a leak or you didn't use an airlock...or maybe you forgot to put water in it.

For most of it's history people made beer without hydrometers...or even thermometers. They did it by being observant. The notion that you have to be some sort of Yeast Whisperer or Beer Savant to do this is ridiculous imo.

It was bad enough that Squirrely decided to take out whatever sh!T was going on yesterday out on me. That's why I pretty much ignored this what did he just call it, "little game", 'casue I knew I didn't do anything to warrant it.


But don't you ever ****ing call me a liar again!!!!!!!!!!!!!!!!!!

Or accuse me of being "misleading."

If I don't see airlock bubbling I don't see airlcok bubbling, several OTHER PEOPLE IN THIS THREAD HAVE SAID THEY DON'T OFTEN SEE AIRLOCK BUBBLING. So shove it up your ass!!!!!!!!!!

I wouldn't say that if it wasn't true....where the **** do you THINK I got the IDEA NOT TO TRUST THE DAMN THING ANYWAY, from my own observations.

I have 9 different fermenters, buckets, carboys, water bottles, whatever, and I have seen airlock bubling maybe half the time....
