Also called a fermentation lock, bubbler, air valve, or water
trap. Easy to clean due to removable internal parts. Allows CO2 to
escape during fermentation, but does not allow air back inside your
fermenter. Essential item on any fermentation vessel.

2/24/2014 – Should the white cap be on the airlock when using the primary and secondary fermenter?
Response From Homebrew Heaven: Yes, and water should be added about 1/2 way up as well.
11/9/2012 – I have seen several questions and answers saying that there are options such as a hole and stopper and airlock on the 6 gallon plastic primary fermenter, but I cannot find these options. I would like to get the fermenter and lid with the airlock, stopper and spigot already installed. I know I have to get the spigot, and it is also in my cart . . .
Response From Homebrew Heaven: Certainly. The Bucket lid comes with airlock grommet installed. No stopper necessary. See links below for airlock and spigot (with installation)
7/27/2010 – I want to buy a kit that would enable me to do both beer and wine. A friend argues I should go with the wine kit and add the beer brewing stuff. Please let me know exactly what I need to purchase. Also, I intend to use ceramic top beer bottles for my beer. What's the best way to clean them? Do you sell the rubber piece (gaskets) they . . .
Response From Homebrew Heaven: In general, I would say your friend is on the right track, assuming you have a lot of flip-top bottles around. Those bottles are pretty handy. See below for a link to the replacement gaskets.If you are thinking of making wine from your own juice, fresh fruit etc, then the 5 gallon wine making kit is a good choice. If you want to make wine . . .

9/12/2009 – If I was to order this Deluxe Kit, how long from the time I start, until I am drinking my first home brew (scottish ale)? What do you recommend getting in addition to this kit, to brew maybe 3 different beers at once, or is that an option with 1 kit?
Response From Homebrew Heaven: A reasonable estimate for that is 3 to 4 weeks from cooking to drinking.In order to brew 3 beers simultaneously, you would need more equipment, primarily fermenters and airlocks/stoppers. A good way to this at a reasonable cost is to start a new batch about every 10 days. As the first batch comes out of the primary fermenter (it gets transferred . . .
8/7/2009 – I was interested in the 10 or 20 gallon fermenters but was wondering if you might be able to install spigot and lid hole with bubbler and stopper?
Response From Homebrew Heaven: We can install the plastic primary spigot without a problem. Due to the loose fitting lid on both of these fermenters, there is no need to use an airlock. It allows enough CO2 to escape on it's own. If you prefer, we can install an airlock and stopper, but as I say, you may not get much bubbling through it.
6/24/2009 – how do you know how much water to add to this air lock?
Response From Homebrew Heaven: It isn't critical how much is used. About 1/2 full is just fine.
7/11/2008 – I"m trying to find some large-mouth balloons,I use for making wine; They fit over gallon containers; Would appreciate any help
Response From Homebrew Heaven: The "balloon wine" recipe has been around for at least 40 years (I did this in high-school), but I should tell you it's a BAD idea. You WANT the CO2 to escape!It is much better to use an airlock and stopper. The CO2 will be released, and it does not allow air or bacteria to get in. For a couple of bucks, it improves your wine and is reusable!By . . .
1/26/2008 – I live about an hour (if traffic is good) from the address on your website. Do you have an actual store or is everything here based solely online?

7/14/2006 – I am about to order a 7.8 Gallon primary fermenter and a 6 Gallon Glass carboy however when I add both items to my basket you ask me whether I would like an airlock and stopper with the items. I immediately think 'yes' but I read on another website somewhere that when the must is at it's primary fermenting stage, it's not good to have an airlock . . .
Response From Homebrew Heaven: At the very beginning (1st day or so) of wine fermentation, your must "likes" a little oxygen, so there is no harm in leaving it open to the air. Yeast doesn't "breathe" but if oxygen is present, it will reproduce faster. After fermentation begins, however, it is best to use an airlock.i.e. I would also get the airlock.
6/16/2006 – Are you supposed to put any liquid into the airlock before you attach it to the fermentor.
Response From Homebrew Heaven: Yes. Fill it about half way up with water.
3/9/2006 – do I need new airlocks every time i make wine?, and what are campden tablets?
Response From Homebrew Heaven: No, the airlocks can be used for years.Campden tablets are potassium bifulfite, compressed into a convenient tablet. You typically use one per gallon of wine.
10/7/2005 – I've heard that during the first few days of wine fermentation, you shouldn't attatch an airlock. You should cover the opening with a cloth or something similar. They say this is because it needs to get air during this time. Then you should transfer the wine to a secondary vessel and attatch an airlock. Is this true, or should an airlock . . .
Response From Homebrew Heaven: Yes, we hear that one all the time too. Folklore is hard to shake.We believe it is better to aerate your must (wine) before adding the yeast if you can, and THEN to add an airlock. It's true that yeast "need" a little oxygen at the beginning, but that is easy to do when you add water, or by shaking stirring etc. Using a lid and a airlock . . .
8/10/2005 – What is the preferred airlock the 3 piece or red top. What are the ups and downs to both?
Response From Homebrew Heaven: Just personal preference is all. Some people like the 3-pc airlock because they can disassemble it for cleaning. The downside is that there are more parts to lose/break. The both do exactly the same job performance-wise.
3/20/2005 – I just bought a wine making kit. This is my second day. Do I put the cylinder air lock on the bucket or the carboy? I did not get any good directions with the kit. When I do put it on, am I supposed to put water in it? Help. I need some advise on this matter.
Response From Homebrew Heaven: Hello Charlotte. I suspect this isn't one of our kits. We provide better directions than that!An airlock is used on whatever you are using to ferment the wine. We encourage people to start their wine in a plastic bucket (primary fermenter), but it can be done either way. The airlock should be filled about half way up with water, and . . .
3/15/2005 – I would like to filter hops, fruit etc. while I siphon into my fermenter. Would any of your screens work well when attached to a siphon hose? Do you have any other suggestions outside of a tapped kettle connected to a bazooka screen?
Response From Homebrew Heaven: The real problem will be getting the stuff thru your siphon hose. If you are willing to pour the wort:In our Brewing Accessories category we have a variety of straining bags that might well serve this purpose.There are also funnels with straining screens that can be used.
3/8/2005 – I have read elsewhere that you should fill the airlock with sanitizer or vodka. What is your recommendation and are either of these liquids a good option?
Response From Homebrew Heaven: I've read this too, and it seems ridiculous to me. Water works just FINE. When actively fermenting, CO2 is going OUT, and bacteria cannot work their way in. I have NEVER heard of a batch being contaminated thru the airlock, regardless of what was used.Problems with using alcohol or sanitizer:1) Sometimes due to temperature and minor . . .
12/27/2004 – With the airlock comes a little top with two tiny holes. Does that top need to be on so long as the water is high enough that bubbles come out from under the water? The pressure in my ferm. built up and popped off the top because the bubbles werent' escaping fast enough through the two little holes.
Response From Homebrew Heaven: Yes, the top should be on, and water filled up about half way. Sometimes, with a very active fermenation this can happen. Just clean out the airlock, put more water in it and replace it. If you like, you can put a couple more little holes in the top. No harm in that.
9/17/2004 – i just got done making some wine do i have to put water in the airlock and if so how much does it need in there? and how long do i wait to see this work this is my first time using a airlock and making wine help
Response From Homebrew Heaven: You fill it about half way up the airlock. When fermentation begins, it will bubble. How long THAT takes depends on many things, what you are making, type of yeast, temperature and many other factors.
8/13/2004 – When u are fermenting something in a container with a heat source underneath can the container be sealed or do u run the problem or to much pressure building up and eventually cracking or shattering your container if so what can be done about this?
Response From Homebrew Heaven: It's a bad idea to seal up ANY vessel when it has actively fermenting liquid in it. Fermentation gives off CO2 gas, and pressure will build up. You need to use a pressure release, like an airlock and stopper sized to your opening.. Here is a link to one
8/4/2004 – Can you use this on a 5 gallon water jug?
Response From Homebrew Heaven: Yes, along with a stopper of the right size to fit the opening. The opening size varies on these, so it is best to measure it.
3/28/2004 – How can you take a sample in "order to test with the hydrometer" without being susceptible to airborne bacteria during or at the end of fermenting?
Response From Homebrew Heaven: The likelihood of airborne bacteria contaminating your beer or wine is really quite low. Most infections are due to equipment, not airborne bacteria. Also, the most critical time is just BEFORE adding the yeast, not during or at the end of fermentation. During fermentation, the CO2 being produced helps to protect it, and afterwards the . . .
1/28/2004 – I had planned on buying a carboy to ferment mead and was wondering about the bubbler setup I should use. I was wondering if this airlock would work with the carboy or is there another type of setup I need to use when using a carboy to ferment mead?
Response From Homebrew Heaven: Yes, this airlock works just fine for mead.
1/11/2004 – We are putting our apple wine in the fermenting bin and we do not know how to work the three piece airlock. Do we need a cork to attach it to the bin or does it just sit on top of the opening? Also do we have to put water in the airlock? Will our wine be ok if we attach it incorrectly?
Response From Homebrew Heaven: Yes, you need a stopper to put the airlock into. The stopper and airlock then go into the opening. Fill the airlock 1/2 way with water. This allows CO2 to "bubble thru" under pressure. Without an airlock, your wine is susceptible to airborne bacteria. It may be fine, but maybe not.
10/9/2003 – Do you put anything in the airlock stoppers and do you use them right after the wine is pressed? The wine is still fermenting in the demi johns.
Response From Homebrew Heaven: Well, the airlock fits into the stopper, and you add water to the airlock. Is that what you mean?Everyone has a different way of making wine, and different equipment is favored by some. Typically, the wine is started in a large bucket (primary fermenter), and then later transferred to carboys (secondary fermenter). It sounds like you are . . .
9/12/2003 – What size stopper or plug do you buy to fit this part? Being the smallest or the next size up from that.
Response From Homebrew Heaven: You buy the size that fits the opening of carboy or fermenter. There is a chart showing stopper sizes available by clicking on the details button for that item.
6/2/2003 – Are you supposed to leave the plastic cap on the airlock while fermenting?If so, how does the CO2 escape?
Response From Homebrew Heaven: Yes, this is often referred to as a "dust cap". If you look very closely at the plastic cap, you will see a very small hole that is large enough to allow CO2 to escape.On the Red Top airlock, there is a gap between the airlock body, and the red cap that allows CO2 to escape.
