Using oxygen in big beers

Postby Calmbrews » Thursday Jul 28, 2011 5:06 pm

Hey guys I'm looking for a solution to use pure oxygen in a big beer I'm Thinking of tackling. In the states there's a Williams O2 wand which pumps o2 into fermenter but they don't ship to AUS. What to some of you guys use?

Hi and welcome, Calmbrews.

Do you want to use the oxygen to aerate the wort before you pitch the yeast, so that the yeast gets off to a good start?

If so, I haven't heard of anyone using pure oxygen to aerate the wort. Airstones with an aquarium pump seem to be the method of choice around here.

If not, let us know what you're trying to achieve.

Cheers,

Oliver

Thanks for reply..

I'm looking to try the dog fish head 120 ipa clone, which uses 2 yeasts. The oxygen would be used within 12 hrs of adding the high grav yeast. It will be added in a starter of fresh wort.

Here's recipe. But I'm looking to use o2 after 2nd yeast added no more than 12 hrs after.
I don't want to go through the labour intensive recipe and screw it by not aerate the brew enough.

Wow, that's quite a beer. FG of 1050 and 20% abv! I'm tipping this isn't your first homebrew? :-)

Re the oxygen, do you know anyone who has oxy-acetylene welding equipment? Perhaps you could borrow their oxy cylinder for four days?

Or you could hire your own on-site oxygen generator ...

Hope this helps.

Perhaps others have ideas.

Cheers,

Oliver

I just did a bit more research.

Here's something from a page on the Grain and Grape website:

The best way to get oxygen into your wort is by using pure oxygen. This speeds up the process and makes oxygen levels more predictable by the use of a flow meter on the regulator. Due to the higher pressure, a smaller aeration stone can be used (0.5mm). Oxygenation times of about 1-2 minutes give the desired levels of oxygen in the wort. Obtaining an oxygen cylinder from a gas dealer can be relatively expensive though.


And a link from byo.com about oxygenating wort.

And something about whether welding gas cylinders are safe for brewing, also from byo.com.

Cheers,

Oliver

I use an air set-up (instead of pure O2) works fine, you just need to leave it for a lot longer... I usually do a half hour or so.

I use an aquarium pump and an airstone to pump air through my wort.

Usually leave it for 15-20mins.

Since doing this i am getting better attenuation and the beers are fermented out to FG in less than 3 days.
