Brewtan B Dosing

Just wanted to do a quick post detailing the required dosing for Brewtan B. There was some discussion recently on another forum and I added to that discussion a quick summary of the current dosing recommendations:

So, to summarize:

VOLUME BASED DOSING

Mash – 1/2 tsp/5 gal (0.1 tsp/gal) for TOTAL water amount in mash (dose based on strike for no-sparge, dose based on strike+sparge if sparging) and add directly to water.

Boil – 1/2 tsp/5 gal (0.1 tsp/gal) in the boil. Dissolve boil dose  in 1/4 cup of water and add at 15 minutes. Add at least 1 minute prior to kettle fining agents.

(Note: Joe F.’s dosing seems to be based off of 4 g/hl or 0.15 g/gal)

WEIGHT BASED DOSING

Mash – Add between 0.08-0.26 g/gal (2-6.84 g/hl) directly to mash (dose based on strike for no-sparge, dose based on strike+sparge if sparging).

Boil – Add between 0.08-0.26 g/gal (2-6.84 g/hl) in the boil. Dissolve boil dose  in 1/4 cup of water and add at 15 minutes. Add at least 1 minute prior to kettle fining agents.

COMMENTS ON BOIL ADDITION

For those using Copper chillers, the boil addition is certainly worthwhile in addition to kettle fining agents due to the copper chiller’s potential for participating in the Fenton reaction.

For those using Stainless chillers, the boil addition shouldn’t be required. Adding Brewtan B in the boil in addition to kettle finings really serves no purpose in the absence of the requirement for metal chelation (from the copper). Since you have theoretically already treated both the mash and sparge water volume prior, you shouldn’t require the metal chelation for your source water either once in the boil.
