Do I have anything to worrry about? Hot Side Aeration.

[Jmac]

I collect my wort after mash in buckets or carboys because I dont have a gravity system. I then pour this in the kettle which makes alot of bubbles etc...


Is this ok? anyone else do this?


Just poured 10 gallons of hot wort in the kettle!!! Rock on ladies and Gents!! Jammin to the radio and makin some beer!! I love it!!

HSA as an issue for the homebrewer has been pretty much debunked over the years..and some would argue even for the commercial brewers...we post this video as an example...If THEY don't get it more than likely, we don't either.

I stir my mash tun after every infusion and before every draining with a paint stirrer on a drill. Come taste my beers and THEN tell me that HSA can mess up a batch. Nuhuh.

We haven't had a good new brewer HSA freakout in months, IIRC...I kinda forgot the words "Hot Side Aeration, boogeyman"

It's BS if you ask me. Wouldn't the boil eliminate any oxygen youve introduced by splashing?

Sweet. I was just curious if my proceess was messed up.. I am not freaking out as it seems my beers are turning out ok but when I poured into kettle today it reminded me of hsa.

Wow, I love this site. Everyone is so helpful!! I feel honored Revy jumped in and assisted with my question. Your a legend!!

If the oxygen were just staying in solution, then that wouldn't be a problem. The problem is that the oxygen supposedly reacts chemically with the wort while it is hot.

Well i drain my MLT using tubing right into the boil kettle to minimize any splashing, but i still do get some bubbling and splashing and have not had any ill affects.

Yeah, a Revvy post What a rarity. That only happens about, oh, a few hundred times a day.

Oohoohoh sh*t. I got you good, you f*cker.

You seem pretty hip too. You kneed to be sure you don't bust your butt shouldering the burden of being waisted...

See that? When faced with your tongue-in-cheek comments, the man still manages to take it on the chin.

I have a bad case of the hic ups!!

Yes, a good boil essentially eliminates all dissolved gases from a solution, which is why we aerate after the boil and cooling.

Forum thought on the topic has come a ways since I posted these pics:

No, because we're actually talking about different compounds that are explained more fully in Fix.

I can't explain the science with enough intelligence, so I'll direct you here.

I think a lot of people are confused by what the term "oxidation" means. For example, while oxygen is certainly a oxidizing agent, oxidation can certainly occur in the complete absence of oxygen.

Any argument about the presence of molecular oxygen in the mash or boil are naive, since we are talking about oxidation which is only a superficially similar word to oxygen.

so if we aren't worring about HSA why do we Vorlauf? couldn't I just run the wort thru a screen to collect bits of grain?

The function of the vorlauf is about setting the grain bed and redistributing the smaller particles to the top for better clarity and filtering.
