    Sanitizer? Vodka? Boiled/reverse osmosis/distilled water? What do you use?

    Filtered Water (from my sink), sometimes Star San.

    Starsan. Though, if I had vodka sitting around and I was fermenting a bigger beer that had a chance of unexpectedly blowing-off, then I'd use the vodka.

    Vodka, but only because I have SO MUCH VODKA that people leave after parties and such and I can't stand the stuff.

    Tap water during fermentation and vodka for long-term storage/cold conditioning/lagering.

    tap water. When I use a blowoff hose I put leftover starsan in the bucket just because the krausen that blows through looks like a path infections could take.

    Re: other parts of the brewing procedure, I switched back to solely Iodophor after I found out Star san reacts with my water and turns beers cloudy (tested at bottling time).

    Relatedly, why is the lock filled with liquid? Is it to create a barrier??

    (This question woke me up a 4am last night, so I thought I'd ask..)

    To keep oxygen out which helps keep your beers from oxidizing as quickly

    Itt creates a barrier as well as keeps oxygen out. Bad microbes can't make it through from outside, and neitther can oxygen. I use start san simply because I don't want a mini cesspool between my beer and the outside world. Some people would rather use vodka incase the fluid sucks into the beer. I personally have never had that happen. My neighbor insists that every batch he has fermented has sucked in a little bit of airlock fluid.

    I work at a flavor house so I have access to tons (literally) of 99% grain alcohol, so that's what I use.

    Starsan for me. In short, it's anything that you wouldn't mind ending up in your beer in case something unfortunate happens.

    Starsan or water... Depends on what is near me at the time. Starsan is preferred, but never had an infection from the multitude of airlocks that have sucked water back into them (damn flexible Better Bottles!)

    I normally though run blow off into water jugs...

    It is sterile.

    I use some of the sanitizer I have pre-mixed, be it iodophor or star san. When I've lagered, I've used vodka, just in case it gets too cold the vodka won't freeze.
