I understand how it shows if the beer is fermenting but serve any other purpose ? The reason I ask is I couldn't find my middle piece when I finished brewing. I just placed the airlock and lid on. I trust it will ferment.
I'm not doubting this works, but I used to do my starters this way. Then one fine day I checked on a starter in a kitchen closet. To my horror I found a trail of ants climbing up the side of the flask, under the foil and down into the sweet treat below. Needless to say I chucked the culture of yeast ants rather than pitch it into brew. I invested in an 89 cent foam stopper and haven't had a problem since. Not every contaminant "falls" in; some "crawls" in!!!I usually let the first few days in primary go without an airlock. I just put on some starsan-soaked aluminum foil. Just after high krausen I add the airlock. All you have to do is keep anything from falling in. After the krausen drops, it's a different story. Less protection up top allows o2 diffusion. But you got a few days before you need to come up with a new airlock.
Thankfully, I've never had this problem. I have taken precautions and I realize that my process is not for everyone, but I wanted to give the OP a little peace of mind. I do believe he needs to airlock soon.unionrdr said:Yeah,those lil ants or them pesky fruit flies!
No. The airlock doesn't affect fermentation. Fermentation affects the airlock.I bought a new airlock today poured some starsan in it and popped the middle piece on. It's been on dry for about 3 days. It's not bubbling should I be worried?
If you have crawly things and want to keep them out of a fermenter put the entire thing in a tub of water with detergent in it or sprinkle some food grade diatomaceous earth around the fermenter in a six inch band.I have found ants crawling over my carboy this spring. The airlock definitely saved the beer from being infested. I believe there are some natural foods toucan place in proximity to the beer that will keep them at bay like garlic or coffee grounds.
Yes. I usually go 3-5 days without an airlock, depending on the yeast activity.joydivision said:So if the krausen has not fallen I'm probably ok? How soon does the krausen fall? I went three days w a dry airlock.
