Airlocks

Airlocks are another one of those necessary pieces of equipment for every homebrewer.  If you ferment in a carboy or bucket this 3 piece airlock is a must! It’s a popular alternative to the triple ripple type of airlock because it can be taken apart and cleaned, and is easy to fill. (However we do sell the triple ripple type (FE371) in case you are used to that type and would like to stay with it.)    While a simple device not all airlocks are the same. Some other designs have only a couple holes in the plastic lid and this can cause the airlock to pop out during an active fermentation.  Our design features multiple holes that allow CO2 to escape easily.  Additionally some other airlocks have a cross hatch design on the bottom. We have found this more easily leads to Krausen clogs and the airlock being pushed out of the fermenter. Ours is open, allowing Krausen foam to enter the airlock if necesary.  Better to clean your airlock out than to find it laying on the floor next to your fermenter 3 days later.     Another cool feature of this 3-piece airlock is that 1/2" ID Silicone tubing will fit onto the center post for use as a blowoff. In the cases where you are using a yeast known to produce lots of Krausen (wlp002 from White Labs or 1968 from Wyeast for example) remove the top cover, remove the plastic 'hat', and install the silicone tubing.  Run the silicone tubing into a jar or bucket of water. When fermentation dies back down remove the tubing and replace the hat and cover.   Please Note: Airlock only - stopper not included.

S-shaped airlocks are the "OG" airlocks for home beer and winemaking. They make it easy to spot fermentation activity, and have no loose peices to lose. The advantage of this type of airlock is that they have a smaller chamber so you can more closely observe the CO2 rising and therefore the rate of fermentation. They are also handy when you are cooling a beer as there is less chance of sucking airlock water back into the fermentation. They cannot be cleaned manually if they get dirty during the ferment. That is why many homebrewers prefer 3-piece airlocks for the active portion of the ferment, when the krausen (foam) from fermentation might be pushed up into the airlock. Please Note: Stopper Not Included.

This oversized 3-piece airlock can hold 50% more water or sanitizer so your airlock is less likely to evaporate dry or get sucked dry. When the temperature drops, your fermenter will suck in solution from the airlock, and if the temperature drop is significant the airlock can be completely emptied. An empty airlock opens the door for airborne spoilants to make their way into your fermenter unchecked. The extra large 3-piece airlock offers your fermenter even more protection, and is especially useful when cold crashing.   While a simple device not all airlocks are the same. Some other designs have only a couple holes in the plastic lid and this can cause the airlock to pop out during an active fermentation.  Just like our normally sized airlock, our design features many holes in the lid that allow CO2 to escape easily.  Additionally some other airlocks have a cross hatch design on the bottom while our is open to allow Krausen foam to enter the airlock if necesary.  Better to clean your airlock out than to find it laying on the floor next to your fermenter 3 days later.     Another cool feature of this 3-piece airlock is that 1/2" ID tubing will fit onto the center post for use as a blowoff.  This can be handy if you have a really active ferment that is blowing out the top of your fermenter.     Please Note: Airlock only - stopper not included.
