View Full Version : Pure O2, Blue Moon Yeast, HELP!

Two questions my friends can help me with. I have an O2 extractor, one of those deals the people with emphysema use at home, producing 96% pure oxygen. I've been using it to aerate when brewing yeast in small batches of sterilized corn syrup and water mix and it seems to be working great in the initial phase toward flocculation.

My question: would it be recommended to go pure O2 with a bubble stone in wort as well, or is that contraindicated? Would yeast overproduce in the first fermentation in a super-oxygenated mix (as noted in a recent thread)? Any other anticipated problems? Of course, I'm using antiseptic technique, so that issue aside.

Also, does anyone know what kind of yeast is used to produce Blue Moon? Is it real Belgian yeast? Is it a wheat yeast, or otherwise. I just drew off from a bottle of Blue Moon, and it's flocculating even while we speak. I am hoping to use it in a batch of my own wit.

I would say that going for both the starter and the wort is possibly too much oxygen.

Just as not enough is a problem too much will cause problems with the yeast. Over oxygenation will cause excessive yeast growth which can result in reduced alcohol production as well as issues with the flavor and aroma profiles. Another concern is stressing the yeast during the propogation cycle, I have seen this one first hand with a new strain being propped up. Oxygen was hooked up and forgotten for an afternoon, the yeast was worthless.


A quick search turns up a decent link to BYO for you on this issue.

Thanx for the link, brewmonkey. And my search reveals that Blue Moon uses a wit yeast. Banana, fruity odor, bubblegum the whole bit.

I've been infusing the corn syrup/water mix with straight O2 before adding yeast, and the Wizard says that's good, but, like you said, avoid during growth phase, and not in Wort at all

You are the man!

I don't like to use a starter. Safer to just buy a second vial of the yeast.

Then, I run oxygen through a stone into my just pitched wort for a full minute. Seems to work for me. I know many are enjoying the Boh Pils I recently brewed. Very clean lager.
