I came across that thread/dosage information too but it conflicts significantly with everything i've seen from the manufacturer. For one, they don't specify quantity in teaspoons. Also as a general policy, I immediately disregard any advice that involves teaspoons or tablespoon measurements because its going to be wildly variable.
I agree that the dosage recommendations seem to be pretty scattered in terms of quantities and timing depending on what source you use. I also agree with measurements using tsp/tbsp when clearly these are substances that should be measured by weight. I bake, therefore I much prefer to use weight and I recognize it's importance in such instances. I do not have BtB but foresee getting some at some point this year, and would like to have a reliable dosage and instructions prior to using. Are you willing to share what have you been able to come up with?
Basically what I've see is the Denny/Joe dosage advice from the AHA forum way that uses teaspoons (see below). The experimental brewing igor experiment dosage suggestions (see below). The Wyeast package instructions (see below). Finally, the ajinomoto pdf dosage instructions (see below).
AHA Forum Recommendation:
Brewtan B Dosage
-1/4 tsp per 5 gallons of all water including sparge
-1/2 tsp slurry @ 15 (i.e. mix BtB with small amount of hot wort to make a slurry)
-Denny posted and I believe Joe said in the podcast that there is no effect on pH
Experimental Brewing Recommends:
Brew the second with the recommended dosing rates (0.5gm / 5 gallons mash/sparge water; 1.0gm dissolved in a slurry and added to boil with 16 minutes remaining)
Wyeast Recommends:
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.
Ajinomoto Recommends:
Due to its strong reducing power and its inhibiting
properties against aldehyde formation Brewtan B can be
added at mashing-in to improve flavour stability. When
used at mashing-in a remarkable improvement of
lautering performance can be achieved, with improve
d brewhouse yields and higher extraction quality.
By using Brewtan B at boiling haze forming proteins a
re selectively removed already early on in the brewing
process and final colloidal stability is significantly
improved. Use at this stage of the process also has a
marked positive effect on whirlpool yields, shorten
s maturation times and provides longer filter runtimes.
Brewtan B is typically added as a 5 – 10 % solution.
Mashing in:
Brewtan B is added in the mashing water before the
addition of the malt, typical
dosage levels are 2 – 6 g/hl.
Boiling:
Brewtan B is added max. 5 min before the end of the
boiling process or during the
transfer to the whirlpool, typical dosage levels are
2 – 6 g/hl.
A combined use in mashing-in and boiling is becoming
increasingly popular in the industry and combines the
beneficial effects of both approaches.
