How do you aerate your wort

[196osh]

A drill with a paddle attahed to it. Aerates nicly.

[mysterio]

I go in with a SS diffusion stone and pure O2 for about a minute while agitating the wort. It is a quick sanitary way of getting the job done.

I drop it through a sieve into the FV. It's certainly good enough for the dried yeasts I use.

Primarily I use Wyeast liquid yeasts.

Mostly I use an airstone and an aquarium pump, until the froth threatens to climb out of the fermenter. I consider it sufficiently done at that stage.

Alternatively, when I use a starter, I will sometimes pour off the starter beer, leaving only the slurry. I pour about 3 litres from my batch onto the slurry in the starter bottle, and I aerate the crap out of that for about 3 hours. The whole starter gets pitched into the batch, which is itself not aerated. Takes off is within an hour or two.

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.

Three weeks ago I brewed an imperial pilsner with dry yeast, didn't aerate, and it worked fine. I pitched the yeast at 3 pm and the airlock was burping every 8 seconds when I got up the next morning at 7. 1.012 after two weeks.

A man after my own heart. I also count the 'burps' as an indication of how well the fermentation is going!

I never would have thought to use a Milk Frother

I use an air bed inflation pump and a length of hose. This works well.

When the burps become one loud B-E-L-C-H you know you're onto a winner. Aeration? Nah, don't bother and evidently don't need to.

I switched to primarily dry yeast several years ago and the only aeration I ever get is a little from transferring the wort from the kettle to the carboy and I've never had a long lag time except for the two times I used Mangrove Jack yeasts.

I just drop the wort into the FV from a height and add the yeast. Fermentation always takes off like a rocket.

Get one of these on your electric drill http://www.ebay.co.uk/itm/Mixing-Paddle ... SwRgJXlPKM
I used to use a length of hose attached to my car tyre inflater but I got fed up lugging the FV to the carport.

`Good thread revival this one, of only to see Whorst's avatar again.

If you use dried yeast and are not looking to brew a BIG beer then it isn't necessary, but anyone using liquid yeast close to or passed its best by date and particularly for brewers reusing slurry, then a shot of oxygen is vital. At the very least a paddle in a drill can get you close but will mix in whatever is in the air too. The ideal solution is pure O2 and a sintered stone, but that needs very careful handling and storage (O2) and the stones easily clog with wort so need careful cleaning. 60 seconds at 1 litre per second is enough for a 25 litre brew.

Excellent I hadn't thought of aeration through the dump valve. I've always just dropped in via the top. Thanks Orlando

I use a spray nozzle on the end of my hose from my kettle to my fermentor.
