I'm going .1g per gallon strike and sparge for mash, and .2 gallon per finished gallon at 15.

Please don't do that.  Please use the amounts and times I listed.

Yes, and he got it wrong.  We discussed it and he's changed the writeup now.  My amounts and times come from the company rep, who is a multi award winning homebrewer.

From the write up - "Joe recommends a dosing rate of 1/4 tsp (0.5gm) per 5 gallons of sparge/mash water and 1/2 tsp (1.0gm) dissolved into a beer slurry and added to  the boil at 16 minutes. It's a wee amount!"

Not trying to argue. You say tomato, I say potato. You use volume, I use mass.

Sorry for the confusion!  Sure, use mass if that's what you like.  But please don't put it in the sparge water.  I think...I'm gonna try to confirm with Joe.

I would interpret those instructions to mean adding at that rate to both strike and sparge water, but I could be wrong....

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.

Yep, you're correct.

Joe is a food scientist who reps the product for the company.  He is also a multi award winning homebrewer who uses it.  You are free to use whatever dosage you like, but I'll stick with what he says.

[Stevie]

Joe's dosages seem to line up within the ranges of both commercial offerings I've seen.  Maybe it's one of those things where too much is too hard to hit.

I understand all of that, but when I buy anything new, I usually look at the instructions that came with it, or find some literature online; I don't seek out a rep from the company to explain it to me.  If I did however, I would imagine that reps advice and the company's instructions would line up.

I appreciate Joe taking the time to talk about it, and you for getting him on the show; but I would like more clarity on those items.  I'm assuming its an issue of homebrew scale vs commercial scale.
