Why are Joe's recommendations totally different from the fact sheet on Brewtan from the Manufacturer?
The manufacturer says this about Brewtan:
Mash - 2-4 g/hL (I do 3.25 gallon batches, so @ 3 g/hL this is 0.371 grams in mash)
Boil - 2-5 g/hL (@ 3.25 gallons and 4 g/hL this is 0.491 grams in boil)
Both doses are added as a 5-10% solution
Both doses are based on final volume of beer.
The final addition is added at most 5 minutes before end of boil or at whirlpool.
Whereas Joe gives his in tsp (which still might be in dose range recs), doesn't use a solution, adds @ 16 minutes, and bases dose his on initial water amount.
Confusing.
I also weighed it out several times on a scale. I had an average weight of about 1.23 grams for 1/2 tsp. Ranges were from 1.13 to 1.28. Which is 25% more than the 1.0 grams per 1/2 tsp mentioned above.
