Aeration equipment

Post by Frothy » Mon Feb 05, 2007 7:17 pm

A recent brew proved particuarly stubborn to ferment.
I'd made a 300ml starter and the only thing I hadn't done is aerate the wort.
I bought a 2micron stainless steel airstone & HEPA air filter from http://www.Beertech.co.uk as they were very reasonably priced. Only to find that these items have 1/4" fittings and my puny aquarium pump is both too pathetic & only equipt with 1/8" fittings.

Solution?Very sucessful & cheap
12v air compressor ~£10.

Use 3/8" OD plastic beer hose to connect it all together, chop the tyre valve connector end off of the pump & use a 1/4" hose joiner -> I also chopped the cigarette lighter socket off & fitted a couple of crocodile clips for using a seperate battery. Image

Works a charm if a little over zealous, probably only need ~ 3minutes of wort aeration with one of these on the go.

good job Frothy, does this mean that you don't need to stir vigorously for about nine hours or use the paddle in a drill etc?

do you aerate just before or just after the yeast is pitched? i aertae just before then stir the yeats in well.

That's what I'd be worried about with that type of compressor....

I understand that it's only designed to be used for short periods of time. With a HEPA filter in the line I think the risks are negligable. The compressor is under very little strain compared to blowing up tyres.

Garth - yeah ideally I'd aerate just before pitching the yeast although this time I didn't have any choice. At least it's going now :)
