What liquid do people use for their airlocks?
I have been using water for a while but have recently seen people who think this isn’t best practice and is likely to get infected.
I have also found out that the sanitizer I use breaks down over time so likely wouldn’t be suitable. I have taken to using dish soap for now but don’t know if there is a problem with this practice.
I am currently avoiding vodka because of the alcohol duty in my country.
I use the sanitizer I’m using at the brew day. Iodofor, Starsan, Alcohol 70%, etc. Have never had an infection, never used tape water though. Just keep in mind that if you don’t have any way of closing the airlock in the fermentation vessel - airlock tube section, when cold crashing, the liquid might get sacked to the vessel, due to pressure difference caused by temperature drop.
I don’t cold crash lol. Do you have a dedicated fridge or something?
Not really, but it’s on my goal. I intend building a kegerator and use my fridge just for fermentation. I cold crash in the same fridge for the momment. Oh, and I do have a valve for closing my airlock, mostly for preventing oxidation tham infections concerns.
