Wyeast Tanal A is a 100% natural, medium- to high-molecular weight tannic acid extracted from renewable plant materials specifically for the brewing industry. It can be used to enhance yeast and colloidal suspension (permanent haze) in beer. It is ideal for Hefeweizen, Witbier, and other styles where a cloudy appearance is desired.
Dosage Rate: 4.5 grams/BBL (4.5 g/1.17 hL) of finished beer. Rate will depend on amount of protein in finished beer. Less will be required for beers containing more protein. The use of a higher dosage will cause some Tanal A to be left as sediment.
Usage: Dissolve in de-aerated sterile water or beer. It is recommended to mix in small amounts, in 250 – 1000 mL bottles, to avoid clumps. Add dissolved solution to conditioning tank prior to or during transfer of beer. Haze production will be immediate.
Note: A small dose of Brewtan B at the rate of 2.93g/BBL (2.5 g/hL) at the end of boil is recommended for any style to remove large chain proteins, and can be used in conjunction with Tanal A.
Stability: Store in airtight container at ambient temperature. Product may be retested after listed Retest date, and may continue to be used if it is still of satisfactory quality.
