Dissolved Oxygen Experiment- Interesting Finds with Beer Transfer Method

[micraftbeer]

Yeah, it is a good day when my spam to legit ratio is only 50:1. If anybody needs leads on increasing their customer retention, or is looking for a vape shop, or CBD, or lingerie, just let me know!

I don't want to reinvigorate the kicking, as I haven't posted the update to my MW600 review yet with the info we discussed here, but I came across one of those random spam comments on my WordPress site today that made me laugh. Below is a comment someone left on my website, attached to my tasting review of Stone Arrogant Bastard. This is the stuff you have to slog through on Comment postings on WordPress. This one in particular made me laugh...

I wish to show some appreciation to this writer for rescuing me from this particular circumstance. Right after surfing through the world-wide-web and meeting notions that were not powerful, I thought my life was done. Living devoid of the strategies to the issues you’ve resolved by means of your main guide is a critical case, and the kind which could have adversely damaged my career if I had not noticed the blog. That capability and kindness in controlling all the details was precious. I am not sure what I would’ve done if I hadn’t come across such a solution like this. I’m able to at this moment relish my future. Thanks for your time very much for the high quality and effective help. I will not think twice to recommend the blog to any person who will need recommendations about this matter.

I wonder how many different places they posted that exact same comment. It's specific to absolutely nothing.

Brew on

Not specific!? You mean to tell me my beer review didn't save that person's life and career? It felt very personal and sincere.

Interesting video of our friend Bassman having fun with a high quality DO meter.

Very happy to hear that you are considering some corrections. That really is the most important thing that can come of all this.

Remember though that measuring oxygen uptake in the brewing process is 4th year brewing university level and will take some time to fully grasp. May I suggest you limit your review of the MW600 to simply measuring DO in water and when oxygenating pre-pitch since that’s all this meter is really capable of doing. Limiting the scope should make the job easier. Consider concentrating more on how to setup, calibrate and then confirm the meters function with zero solution.

Be glad to help if you run into issues. Also maybe think about posting the drafts of any corrections here so everyone can weigh in on it.

Hope that helps.

Apologies for resurrecting an old but quite 'energetic' discussion, could I ask @Bilsch to help clarify if my method if using the MW600 would be correct?

My intent is exactly as you describe - to measure DO in my wort after it's been brought to pitching temps but before oxygenation via a carb stone. This is at the 1BBL scale and my presumption is I can use the meter hung through a top 1.5" TC port, submerged just under the surface while providing O2 through the carb stone located towards the bottom of the fermenter.

Would the motion provided by the bubbling be sufficient to provide an accurate measurement of the DO ingress on the fly, so that I simply wait to hit my target ppm number on the MW600 and then cut off the O2? Or is there a smarter better way that others do this?

WordPerfect for DOS, run off 5-1/4" floppies.

WordStar, FTW.

Carry on

 

[PCABrewing]

WordPerfect... Probably shows my age. Or anyone that knows what that program is!

I used WordPerfect 3.0 back in the DOS days.
Then I worked for a consulting firm that specialized on the legal market helping firms complete the "inevitable" transition from WordPerfect to Word.
If you ever wanted to know how to get entire staff of legal teams to hate you, that was it.
WordPerfect was clearly the superior product at the time up the point that they tried to develop for both Windows and OS/2.
That's when they started to lose ground.

Did you ever get to see financial managers being forced to go from Lotus 1-2-3 to Excel? Good times.

 

[mac_1103]

Yes, WordPerfect was by far the superior product. And I loved Louts 1-2-3 almost as much as I love typos.

so... anyone still On Topic?

After you've been around here for a while you'll notice how threads can wander a bit, sometimes like a high school marching band on meth.

It is a tough and expensive topic. To answer your last post, maybe without confidence. My understanding is that one can not really trust the readings of a lower cost DO meter. Sadly lower cost is under $700-$1000. I tried to research this and realized I was better off just consulting the few folks that had expensive meters and setting a ballpark procedure.

I know this is a crap answer but it is sadly the case. DO is a tricky measurement anyway because there is absorption so the readings fluctuate as saturation takes place. So if anything, during oxygination you would want to add some O2, wait, take a reading, add some more, take a reading etc... until the numbers stabilize. If you are using oxygen scrubbers like sulfites the process is more complicated as they are eating the O2 as you add it. So you first need to see when they are expended to know you are net adding O2 to the wort.

I would use your meter, keep constant motion and monitor your batches. As a whole, the group tends to favor over-oxygenation than under. I do 2 min at .12 LPM, let rest while I empty the boil kettle then add 2-4 minutes at .5 LPM. Personal experience is going to be your only guide as most of the "others" were kind of shown to not be welcome here. So you are not going to get the answers unless you join elsewhere.
