Brewtan B- 1 oz Bag

One ounce bag of Brewtan B (formerly called Tanal B). Brewtan 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.

In the mash: 1.5 grams per 6 gallons of mash liquor.

In the boiler: 1 gram per 6 gallons wort (5 g/1.17 hL).
