Brewtan B

Brewtan B (formerly called Tanal B) is a 100% natural, high molecular weight tannic acid extracted from renewable plant materials specifically for the brewing industry. Incorporating Brewtan B into your process will improve the shelf life and enhance the flavor and colloidal stability of your beer.

The gallotannins in Brewtan B react with wort proteins through adsorption and precipitation - the Brewtan B/protein complex is left in the spent grains when Brewtan B is added to the mash, or removed in the whirlpool when it is added to the boiler.

It is highly effective at coagulating and flocculating proline and –thiol –containing proteins, but does not interact with foam-positive proteins. This in turn inhibits downstream lipid and protein oxidation, improving flavor stability and shelf life.

Dosage rate:

In the mash: 8 grams per barrel of mash liquor. In the boiler: 5 grams per barrel of wort.

Usage: Dissolve powder in warm water; add solution to mash, boil, or both.
In the mash:

Add solution to mash water prior to dough-in. In the boiler: Add solution 0-5 minutes prior to end of boil.

Stability: 1 year, stored in airtight container in cool environment
Packaging: available in 1-, 3-, 10-, 25-, and 50-pound units
