I have been able to get some antioxin sbt (45% potassium meta, 45% ascorbic acid, 10% gallotannines).

Cf. http://www.lowoxygenbrewing.com/wp-content/uploads/2016/11/ANTIOXINSBT.pdf

Any suggestions on what to do with it? I already have and use sodium meta and brewtan b.

5-10g/hl in the water before dough in.

Yes, obviously, I can read the instructions - but I was looking for something more interesting, like combination with so-meta and/or btb, or not in mash, etc.

No, SBT is basically the holy trinity of SMB, AA, and BTB. Deoxygenate the water, add SBT and call it a day.

Gallotannins is 10%. So at 10g/hl we get 1g/hl gallotannins which is a lot less than the recommended 8 grams per 120 liters in the mash for BTB.

Does anyone have a MSDS, or sheet showing what BTB gallotannin % is?

Is this product more efficient than only using Sodium Metabisulfite?

Only thing I can find is that BTB contains max 1% gallic acid http://www.ingredientsnetwork.com/brewtan-b-prod645735.html

Supposedly! Its another way for folks to lower their SMB rate while still seeing the benefits of a much larger dose, without the side effects (too much sulfur).

Yea so without knowing the materials in it and the %'s, we can't say if the dosage rates are true.

Homo- where did you get that ratio from (45/45/10)?  I am speaking with them directly and it's not aligning. Thanks!

Really cool, is this available to home brewers?

The smallest amount you can buy is 1 kg. A fellow-homebrewer bought it (directly from Italy), and distributed it amongst a number of people.  He printed the composition on a sticker to send along. I've asked him where he got that information from...

[EDIT: apparently it was printed on the 1 kg package, and he copied it on a sticker. The order was:
Antioxin SBT kg 1   3353712   1   €24.50]

[EDIT2: it's not Aromax, right? That has a different composition: http://www.aebafrica.co.za/antioxy/AROMAX_depliant_inglese.pdf]

No, not in the US.
