Using an airlock in a carboy is a simple process. The carboy should have been cleaned and sanitized prior to use. An airlock is a specialized device inserted into the carboy bung to allow gas to escape while preventing air from entering.
In order to use an airlock, first attach the airlock to the carboy bung by inserting the stopper with the attached airlock into the carboy. While some airlocks come with pre-drilled holes, others may require the user to drill a hole.
Ensure the airlock is fully seated in the bung before drilling. Next, fill the airlock with a suitable liquid, usually a half-and-half mixture of water and a sanitizing solution.
To begin fermentation, add the yeast or other starter culture to the carboy, also ensuring it has been sanitized. It is important to top up the carboy with liquid such as a previously made beer, or some sort of nutrient solution depending on the desired fermentation goals.
At this point the airlock should bebubbling, indicating the yeast is doing its job.
After fermentation has finished and the airlock has stopped bubbling, remove the airlock and replace the bung. Now the beer is ready for bottling, kegging, or other desired packaging!

What is the purpose of an airlock?
An airlock is used as a barrier between two air spaces to prevent air from mixing. This is typically used when one space is at a different pressure than the other, such as when going from the outside of a spacecraft to the inside.
Airlocks also prevent air from escaping when a door is opened, which is important for maintaining a habitable environment.
Do you put water in an airlock?
No, you don’t put water in an airlock. An airlock is a device that helps to prevent contaminated air from entering a sterile environment.
What do you fill airlock with?
An airlock is a chamber used to Equalize pressure between two environments. When you open a door between two areas of different pressure, air will rush in or out until both areas have equal pressure.
Airlocks are used in spaceships, submarines, and other sealed environments where it is necessary to Equalize pressure before entering or leaving.
Airlocks typically have two doors, one leading into the sealed environment, and one leading out. To Equalize pressure, you first close the door leading into the sealed environment. Then you open the door leading out, allowing air to rush in or out until the pressure is equalized.
Finally, you close the door leading out and open the door leading into the sealed environment.
Can you ferment without an airlock?
You can use a airlock or you can use a solid lid with a hole punched in it and covered with a coffee filter or cheesecloth secured with a rubber band. The airlock is just there to allow gas to escape and keep contaminants out.
Does fermentation need to be airtight?
No, fermentation does not need to be airtight, but it is important to keep oxygen out of the fermentation process as much as possible. Oxygen can cause spoilage and off-flavors in beer and wine, so it is typically removed from the fermentation vessel using a airlock or some other system.
Should you Stir wine during fermentation?
Stirring wine during fermentation can help to release carbon dioxide gas and prevent the wine from getting too yeasty. However, it is important to not stir too much or you could end up aerating the wine too much.
How do you make a sulphite solution for an airlock?
As the amount and type of sulphite needed for an airlock will vary depending on the specific application. However, a general method for making a sulphite solution for an airlock would be to dissolve the desired amount of sulphite in distilled water, and then add the solution to the airlock.
How long does it take for the airlock to start bubbling?
It depends on the size of the airlock, the amount of fermenting liquid, the temperature of the liquid, and the type of fermentation. In general, the airlock will start bubbling within a few hours to a few days.
Do I need to change water in airlock?
Airlocks are used to release pressure in a bottle without allowing air to enter. This is done by submerging the airlock in a small amount of water. The water provides a seal that prevents air from entering the bottle.
Over time, the water in the airlock will evaporate and will need to be replaced.
Is airlock necessary for fermentation?
The first reason is that airlock prevents oxygen from entering the fermentation process. Oxygen can cause oxidation, which will ruin your batch of beer. The second reason is that airlock allows carbon dioxide to escape.
Carbon dioxide is a byproduct of fermentation, and if it builds up too much, it can explode your container. The third reason is that airlock prevents bacteria and wild yeast from getting into your beer.
Bacteria and wild yeast can cause your beer to spoil or taste bad.
Can you use vodka in airlock?
You can use vodka in airlock, but it is not recommended. Vodka is a distilled liquor and has a high alcohol content. This can cause the airlock to become full of vodka very quickly, which can lead to problems with the airlock or the entire system.
How often should my airlock bubble?
This is a difficult question to answer definitively because it depends on a number of factors, including the type of airlock you are using, the temperature and humidity of your fermenting environment, the alcohol content of your fermenting beer or wine, and the CO2 production rate of your yeast.
In general, though, you should see bubbles coming through your airlock at least once every minute during the first few days of fermentation, and then at decreasing intervals as fermentation slows. If you see no bubbles at all for 12-24 hours, that’s usually an indication that fermentation has stalled and you should take action to troubleshoot the problem.
Should I use an airlock during primary fermentation?
Using an airlock during primary fermentation is not necessary, but it can be helpful. Airlocks allow carbon dioxide to escape from the fermenting beer, which can help to prevent oxidation. In addition, airlocks can help to keep out contaminants, such as wild yeast and bacteria.
Are airlocks necessary?
Yes, airlocks are necessary for two reasons. One reason is to keep the air inside the space station clean. The other reason is to keep the space station from being damaged by space debris.
Does primary fermentation need oxygen?
Primary fermentation generally does not need oxygen, because the yeast produces enough oxygen during fermentation to meet its own needs. However, some styles of beer (such as Belgian-style lambics) are intentionally fermented with oxygen to produce a specific flavor profile.
How do I know when primary fermentation is complete wine?
You’ll know primary fermentation is complete when the bubbling in the airlock slows to about one bubble every few seconds. At this point, you should rack the wine into a secondary fermenter to clear it of sediment before bottling.
