My 50 cent wort aerator

[Walker]

What I am doubting is whether I can still sire children at this point.

I'd bet your third nut that you can't.

I'd bet your third nut that you can't.

That, along with the other two nuts I've already wagered, belongs to my wife. So if I lose any of these bets, you'll have to take the issue up with her.

So, how long after this aeration do I have to pitch ?

That is a question of temperature. If you have dropped the temp down to pitching range, go ahead and pitch. The aeration doesn't change anything there.

What I mean is,
For how long does the added oxygen remain in the wort ?
I xfer from kettle to carboys in garage, and sometimes need
to wait for my son to tote to the basement because of my sore back.

Well, if it weren't for oxidation reactions, a solution at or below the saturation point would retain all of the dissolved 02 so long as the atmospheric pressure remained the same or greater, and the temperature remained the same or lower. But... oxygen does react with the wort to form compounds we don't want. That's the reason it's recommended to avoid aeration once the yeast have started active fermentation.

Basically, it's best if you get the yeast pitched as soon as possible after aerating. You want them to hurry up & use the o2 for their purposes before it can react too much w/ the wort. If your current process has you waiting a significant amount of time between aeration & pitch, it might be better to try to avoid aerating the wort at all until you do. Transfer from kettle to primary the way you'd rack into a secondary to minimize air pickup, and then aerate when you pitch.

But I don't know how long you're waiting? Might not be long enough to be of consequence.

Short video I made to demonstrate the wine airator. I was thinking more about it and I might have oxygen flow into the venturi inlets when I do this. Although this probably works pretty well.

Curtis!!!!!!!!!!!!!!!!!! How'd you find me! lol You are brewing too?? How's your tank doing? Does brewing get in the way of doing WCs for you too? Sure does for me

Nice, MILES!!! Glad to see we have more in common. Ya, I just started my first batches a few days ago. I am stoked on this new hobby. I love me a good brew, and don't mind the money I save. Also don't mind the work involved, it's fun.

Thanks for the video, I was picturing something completely different. It looks like that works pretty well.

I just use a large plastic funnel, and pour directly into the carboy (though I used a strainer for the last batch of pumpkin ale).

Had almost no lag time, and within 3-4 hours, was getting happy fermentation.

Yah i love this hobby. Brew day is a blast. As you can see in my sig i've got several batches under my belt. I just brewed an american pale ale and hit all my numbers for the first time the other weekend so i was stoked. Stay in touch!

Go Ducks!!!

Sorry for the hijack everyone.
