Putting back on airlock

[BrewBama (Dwain)]

If you got a lot of Krausen into the blow off, then I would replace it with a clean air lock when fermentation settled down.  Maybe that’s unnecessary and I’m just being too anal, but I would prefer the clean air lock in this situation.

That’s cool. I like to solve problems as they arise.  Cause and Effect: i develop a plan and IF something comes up, THEN I address it.

In this case I might clean the tube or just let it go (if everything else is fine) until i clean the fermenter. All depends where i am in the process.

I have had blowoff more times than i can count. A brush and water cleans it right up.

I have had a tube block once because the ID was too small. I increased the tube ID to eliminate that issue.

I leave a blowoff tube on from start to finish. No need to change air locks.

I saw on line that it’s good to put the airlock back after all the crazy fermentation is done. Next brew I’ll start and end with it.

I can’t imagine what the difference would be.

They didn’t go into why so I couldn’t tell you.

My guess is that they didn’t go into why because there is no reason.  Functionally there is no difference.

Listing to all you guys I am willing to be they just wanted to sound smart. Every hobby has them

I always used sanitizer for the blow off or airlock, occasionally some old cheap vodka.

I used Starsan in my airlock for a while, but with a vigorous fermentation the sanitizer would bubble and get pushed out of the airlock and it would start to go empty. I got tired of refilling it, so I just use clean water now.

Same here…started with vodka, went to Starsan, now water (unless I already have Starsan mixed up).  Haven’t seen any difference.

How would hard water be in a airlock. I got hard water by me. When I brew I use Poland Spring since it says it has low ph and I like how it taste

The water in a blowoff jar doesn’t matter. I use the sanitizer I sanitized the fermenter with just prior to transferring the wort into it. But I have used tap water as well.

Cleaning/sanitizing I’ll use my tap water. Brewing its porn springs water.

[emoji106] An airlock is an airlock, whether a plastic bubbler or a hose stuck in a jar. I see no advantage to changing near the end.

If you’re going to open your fermenter do it while there’s still yeast activity so the yeast can cleanup any O2 you’ve introduced.

Not only that, but you have a large blanket of CO2 on top of the beer so you will be OK.

[BrewBama (Dwain)]

[emoji106] Left undisturbed I would agree there is a blanket of CO2 on top of the wort/beer.

However, as soon as the turbulence from opening the fermenter stirs the air with CO2, that blanket is mixed up.

Add hops by pouring them into the liquid or throwing in a hop bag and more mixing occurs.

The active yeast will push the mixture out the blowoff and if any O2 was inadvertently introduced to the liquid they will consume it.

I haven’t done any dry hopping yet I honestly don’t know why people use a hop sack when hops are a natural disinfectant and will not cause any infections to the beer if they sink to the bottom it’s not going to case any plugging issues. Tho I would cold crash to have all the hop floaters sync to the bottom with the trub
