IIRC brewtan B does not keep O2 out of solution, it just prevents it from reacting with the contents of your mash/wort. If thats the case measuring O2 may not be a good way to see if it's working.

too slow!

Oh, so you might see the same O2 level for both batches. Gotcha. If it were SMB, you might see a difference because SMB scavenges O2 and Brewtan just blocks the reaction with the malt (or whatever magic is going on). I have now made 4 brewtan batches... an Amarillo-Citra Pale Ale, a Helles, a pale ale with Santiam and Crystal hops and then the pilsner with S-189. I sure hope the brewtan doesn't do anything adverse to the beer or I'm out 20 gallons of suds!!

The Brewtan-B sample might have more O₂ since the oxygen in solution didn't react with anything in the beer.

I'm 3 batches in with the brewtan. Not that I have anything to compare it to, I'm still interested to see how the beers come out.

man, you guys are dedicated!  I'm not sure I'd go past 1 batch fully blind.

Why?

[matt6150]

Why?

It might ruin the beer!

[shaggaroo]

Maybe brew two identical batches, one with and one without the BrewTan, then run both on an LCMS and see if there are different components present.

Has anyone deduced gram weight dosages for this yet @ 5 gallon batch size?

I just weighed out a level ¼ tsp and it came to exactly .5 grams. I did it again and it came to 1.0 gram. That's the best I got.

I'm trusting Formanak. 1/4 TSP in the mash, 1/2 TSP rehydrated in the boil at 15.

Rehydrated? Is that just dissolving it in water first to avoid nucleation/boil over or is there some special procedure?

This is what I've done now four times.

I just take a little bottled water in a small bowl with a lid, add the ½ tsp of Brewtan, put the lid on, shake it and add it between 10 and 15 minutes before the end of the boil.

why boiled water ken?

[ChicagoWaterGuy]

I use one of those 2 ounce bottles that you get gypsum or calcium chloride in. Put the water in first then add 1/2 tsp Brewtan and shake, shake, shake.
Joe said to dissolve the boil addition in water first. I honestly don't know the reason.

Yeah, I'm not sure of the reason either but the brewtan dissolves in the water pretty easily.

bottled.

derp!

No way.  My initial testing so far shows that there is no downside to Brewtan use in terms of beer quality.

Don't you have measuring spoons?

I'm glad it sounds like it's working out.  all I meant was that when I introduce something new to my process I like to taste the results of the first batch before brewing the next using this new process.  at this point this seems pretty low risk given the amount of good results but some of you guys dived right in before hearing much about the results.  it's just an example of my risk averse nature.

There was some talk about how many things come across differently when O2 interaction has been lowered or taken out of the equation. Some people have said that the beers seem maltier as Denny mentioned. Others mentioned that crystal malts take on a completely different character and that hoppy beers come through with much better hop clarity & character. The GBF guys mentioned trying to achieve "IT" which is fine but I like the idea that MANY styles could show the benefit of the low-O2 (or low O2 interaction) process. This is one reason I did two hoppy pale ales, a pils and helles... trying to cover all of these spots. My next lager will be my Bordertown Dark Lager (a sort of Negra Modelo-style beer) so I can see how brewtan impacts a darker beer.
