How do you aerate your wort

Post by PaulStat » Fri Oct 02, 2009 8:52 am

My usual method is drop the cooled wort from the boiler down into the FV from about a 2ft drop. Last time however the run off from the boiler got stuck meaning I had to jug a sieve so the wort wasn't very well aerated.

So I've invested in one of these for such circumstances.

I inadvertantly aerated a kit brew yesterday by pouring the wort from one FV to the other, and then back. From a 6g sachet of yeast, it has the largest foam head I have seen to date! :shock:

I was actually trying to reduce the temperature of the wort to pitch the yeast but that didn't work very well :lol:

Mine goes through my counter flow cooler then drops through a seive into my FV. Never had a problem with a stuck fermentation yet.

I just let it run from one FV to another via a Collinder. Not had any problems yet.

Semi-long drop through sieve then after the yeast is pitched I give it a good thrashing with the paddle ;)

All methods listed here work fine - letting the wort drop into the FV from a height should provide enough oxygen for a healthy fermentation. Can't remember where I read it but I recently attached my beer paddle to an electric drill, set the speed to medium(ish), stuck it in the wort and gave it a good blast. If you try this, be sure to move the paddle about as if whisking, rather than just sticking it in the centre; otherwise you'll form a giant whirlpool and could end up with a nice 360 deg splashing of wort around your FV! #-o

If I'm using Nottingham or Windsor I don't bother. Danstar state "It is unnecessary to aerate wort."

That is true up to a point....if you are brewing a beer up to 5% then you are all set with your dry yeast. If however you want to do a higher alcohol brew then you will benefit from aeration, I use a Stainless Steel 2 micron diffusion stone and an aquarium pump with a sanitary filter in between. I usually let it bubble away for 20 minutes and have good results with the setup.

How long do you oxygenate for, 30 seconds or so? I have looked at these and toyed with the thought of getting one, have you noticed a marked difference in your ferments?

How did I guess that any of the chaps from over the pond who answered this post would have bottles of o2 and SSteel Air stones :D

What would that cost over here?

I must say, I have looked and have a HEPA filter for an air pump and enquired about a SSteel air stone :oops: .

I like to chuck a few Piranha in and a James Bond villain that works quite well. :lol:

I have the kit and don't use it any more if you want it :D

Why use o2 or even aerate at all when it causes oxidation of the wort? Just add a tiny drop of olive oil to your starter, Carapelli works best :=P

I usually oxygenate between 45-60 seconds. I get fast very fast starts. There are many ways to this, but I prefer pure oxygen.

Regarding olive oil:

I thought "like heck am I adding Olive oil to my beer", so looked it up. Interesting, at least... Increased Esters would be good for a lot of ale styles
