This airlock or fermentation lock is filled partially with liquid (water/vodka, whatever) and it sticks in the
top of a drilled stopper and into the top of your fermenter. It allows the fermentation gasses to escape
without allowing anything to float down into your fermenter. You should have several airlocks and a few
extra (trust me on that one).

    More difficult to fill, clean, and just use in general than the three piece airlock. At least it only costs a buck.

    I have both double-bubbler and 3-piece airlocks. I have often heard or seen it stated that, “The double-bubbler is harder to fill” or, “The double is harder to use” or,”… harder to clean.” While I do not believe that either airlock is superiour I do want to come to the defence of this oft-maligned champion of sanitary fermenting.Is far as filling is concerned, it really is no harder to pour liquid into one than into a 3-piece. Ummm … harder to use? Um … stick it in your stopper. Cleanup is straightforward. Toss it into a bucket of PBW, B-Brite, or your cleaner of choice with all of your other little items for a soak and it cleans up just as well and easily as the 3-piece airlock. I will concede that you might have to shake it a bit to get the airlock full of cleaning solution. Is a benefit I have found that it seems to take longer to dry out during a vigorous fermentation than a 3-piece airlock. I have never actually measured, however.Ihere are fewer parts to get lost or broken (both of which I have done) than are associated with a 3-piece.It really comes down to opinion, I suppose. I use both styles.
