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.
