How do you oxygenate your wort?

[Bobby_M]

I put a little video together showing how I use my oxygen system. Beware, not for dialup, it's about 15 meg but it will stream.

[JimiGibbs]

I've been looking at the oxygen systems as well. Right now I splash it up with my immersion chiller, once it has cooled, and then since I use a bucket as a primary, I pour it back and forth from my brew pot a couple times....

Rich, I think this is one of those simple steps to brew improvement (not suggesting you need it but...) WELL aerated wort really gives your fermentation a boost which in turn gives your brew a boost. Quicker fermentation, cleaner product. I say get the system and enjoy the benefits.

And once again, Merry Christmas!:fro: :fro: :fro:

I'm convinced. If for no other reason I am tired of shaking the carboy and I don't even think it is very effective. This will be my next purchase.

Merry Christmas Brewpastor!

Next time im at the hardware store i will pick one up.

Oxygen regulator for small cans $35 seems expensive perhaps the hardware store will have them for cheap

Found this one for $15.99 would it work? (doesnt look like it would fit a small can)

 

[Bobby_M]

Your only option besides getting that $35 reg is to find a used MAPP Gas + Oxygen soldering/brazing rig. Lowes sells the kit for $49 and includes both tanks of gas. The oxygen bottles are LEFT hand thread.

Here's the regulator only at Williams Brewing for $17.90.

[Bobby_M]

That's def the cheapest I've seen this reg. Get it. As you can see in my video, if you're using the cheap aquarium stones, you'll need to attach it to something rigid because it's gonna want to float up on you. That's why the stainless stones are nice I suppose, but they're not cheap.

Thanks for the feedback unfourtantly canadian homebrew websites don't even come close in comparison with the selection or prices of most american sites.

I am most defiantly jealous of the more popular US homebrew sites.

I would order from these american sites and pay the shipping to Canada but canadian customs and many other fee's/taxes would make it ridiculously expensive.

Have a look at some hardware stores and see what they have for selection and prices.....if not i will just dig deep and buy the damn thing from that canadian website for $36 + shipping.

 

[Brewsmith]

I use the combo method shown by Chimone. Spalsh like crazy into the fermenter through a strainer, then shake the crap out of it.

 

[Orfy]

Do you think this'd work?

Could I make one from copper?

It looks like it would work to me but I'm currently 3 sheets to the wind so you may not want to consider my opinion.

 

[Brewtopia]

[I'm currently 3 sheets to the wind /QUOTE]

You too eh?

 

[Orfy]

I'm currently in post hangover phase. Things have stopped swaying, I'm just a little delicate. Probably 3 hours away from my next Ale.

 

[Yuri_Rage]

Lucky you guys - I've come down with one of the worst head colds I've ever had. Currently typing in delirium at 4:30 AM because I can't sleep. Wish I were drunk!

 

[Orfy]

Bad luck Yuri.

It's 11:30 am here. Just had christmas breakfast and the wifes watching here dog training dvd I bought here. Peace and quiet. Just what the Dr. ordered.

just as of last week i was looking into getting an o2 system. when i do full boils i belive i will get this system. right now im only doing 2.5 gal. boils. so i was talking to some local brew people in my area and they gave me a new way to get more o2 into the wort without shaking a carboy pooring from one container to another. so i used an mix stur. its used for wine making but does a super job at mixing up the wort in a carboy

ill soon post some images of how good it works

I need to find me one of those!

 

[Bobby_M]

I hate to be the continuous devil's advocate but I have to chime in again and say that frothing up the wort is still not oxygenating. I'm sure there's got to be some level of oxygen that is absolutely required and maybe once you reach that point, additional saturation is wasted or even harmful, but I wonder if you can reach it without an O2 system. As I mentioned, the air we breathe is only 20-21% oxygen. The rest is Nitrogen and small traces of other stuff (including wild yeast and other nasties). Maybe you can take totally depleted wort from 0% to 5% O2 saturation by aerating, frothing, shaking, or pumping. I'd think you'd have to do it many times though because the foam will fill your headspace and then you'd have to let it settle before doing it again (and again). Doing it once probably gets you to maybe 1% saturation (I'd love to see some data on this).

I do believe making wort foamy with air is better than nothing at all, but my experience tells me that your ferment will start in half the time with pure O2. Maybe it doesn't matter enough to justify the $30-40 it takes upfront, but it's a part of my brew process from now on.

 

[Bobby_M]

I was actually suggesting that a regular blue/green diffusor stone would want to float. I realize the stainless is heavy enough to attach directly to vinyl tubing.

I do agree that the filtered air system is the next best thing to pure O2. I believe all you do is sacrifice time. The upfront costs are about the same with both methods but O2 requires refill costs. So time vs. money like everything else.

I use a large 02 tank from the same gas place I get C02 from. With a .5 micron stone and a precision regulator, 5 minutes at 15 psi. Not only has this made a great difference in my fermentations, but after 50+ batches the tank is still mostly full.

I went to the local medical oxygen place and they snootily told me O2 was a drug that I could only get with a prescription. I could have sworn O2 was a gas available (at 21%) in the air we breathe every day and not a "drug" which the FDA defines as a substance that alters the body chemistry to achieve a desired effect - or some such terminology. So, until my friend graduates from med school and can write me a prescription for this mysterios "oxygen" substance, I have to look elsewhere...

I asked about purchasing O2 from my local National Welders branch that sold me my CO2 and all the fittings for my multi-tap kegerator. They said that their O2 was "not medical quality O2" which meant that " there could be traces of oil in the tanks although there shouldn't be any."

Does anyone besides Jsin use welding-grade O2 and have you ever had any adverse effects? I surely wouldn't want to risk a batch of beer, or my health, if there's a good chance there's going to be some oil in the O2, but if the chances are small (1:100-ish or less), then I'd go for it. Any words of wisdom?

Like I said before right now I'm doing small 5 gal batches and I’m only boiling 2.5 gals. now I’m not to good with science, but the other 2.5 gals still have o2 in it the other 2.5 that I boil yes the o2 gets depleted. When I combine the two and stir them up I’m mixing back in some 02 and maybe getting some more. I like the method I’m using because I see it as less of a chance of contamination and hopefully less of chance of the carboy getting away from me while shaking it. Like I said I’m not all that great with science I just know what works for me. And using this method with a starter fermentation started in 6 hours. I’m still new to brewing and always open to new methods.

 

[Bobby_M]

Yeah, with a half boil I don't see it as mandatory.

Regarding O2 being a drug, it is, especially when you're talking to a medical supply joint. You can actually die from breathing too much of it (100% O2 that is). The only reason I know this is that I'm certified to dive on Nitrox or enhanced air up to 40% O2 and knowing the point when you'd black out on it is essential.

I doubt there's enough contamination in welding grade O2 to worry about. They just have to tell you it's not medical grade for liability purposes in case someone wanted a bargain on grandma's O2 supply. Bad to breathe the entire tank down, but to add O2 to your wort, nah.

 

[Jsin]

They have to tell you it is not medical grade gas at the welding shop. But there has never been oil in my oxygen bottle. You would know because oil will not go threw a .5 micron diffusion stone. That and when welding if there is oil in your oxygen you get flair ups. So if you see welders buying gas from that gas shop it is ok to use. :rockin:

The LHBS recommends getting the O2 from the hardware store so I don't think it is an issue.

 

[FlyGuy]

About 2-3 minutes. Nice marketing tactic Williams . I don't crank it wide open either. Ok, maybe it's 5-6 batches.

I use a similar system, but only oxygenate for about 30-40 seconds. That has always been sufficient for me. Have you confirmed that 2-3 minutes is necessary?

Mailman just delivered my new oxygen regulator and stone from Williams Brewing. Now I need to brew!

No confirm, but not sure how I would. Probably just being on the safe side...
