Is there a guideline as to the upper limits of sauermalz and lactic acid one would want to add?

3% sauermalz is subtly beneficial to flavor without any suggestion of sourness whatsoever and I believe Weyermann has on its website a recipe for a Berliner Weiße that calls for 8% (IIRC) so clearly there is some sour perception there. I guess I would not go above 4% without trepidation. As always, your best answer will come from experimentation.

First, let me say that the instructions in the original post are very clear. The only ambiguity I saw was,

"For British beers: Add 1 tsp gypsum as well as 1 tsp calcium chloride"

This was clarified later in the thread, and, if I understand it correctly, this is in addition to the baseline that already adds 1 tsp calcium chloride, so it would total 2 tsp calcium chloride and 1 tsp gyspsum. It may make sense to edit the original post to make this completely clear.

The other piece of info I picked up later in the thread is that for 1 tsp we are assuming 5 g. Perhaps the original post should be converted to grams.

Thanks so much for this.

I'm pretty sure it is one of each. Calcium chloride for the baseline PLUS one of gypsum if you wish to accentuate hope bitterness. Yooper posted the sticky from her account so AJ can't do a direct edit.

No, but if AJ wants me to edit the post, I'll certainly be willing! I am LOVING this water chemistry primer.

I also appreciate that it's not called "Water Chemistry for Dummies"! This is still quite a bit over my head, but the light is going on mroe and more for me and my last beers, brewed a couple of weeks ago, are definitely "shining" more than before.

One question- I saw a question about the max % of sauermaltz recommended before flavor changes occurred. I also saw the question about lactic acid. I have never used lactic acid to adjust mash pH but one of my friends does. At what point do you get a flavor from the lactic acid?

I'd certainly like clarification on those questions if possible. My assumption was that for British/Pales we were to add 1 tsp of each (gypsum and cal chl). Also, I've been assuming a tsp of gypsum = 4 grams while a tsp of cal chl = 3.4 grams. Those figures were given in Palmer's book so that's what I've been using personally and what I've given as information in my brew chart. If we're supposed to be assuming something different I'd love to know so that both myself and anyone using my brew chart have the best available info.

Thanks.

I'm pretty sure AJ has said that the amounts aren't super critical. Think about it. This is just a starting point and doesn't take grain bill into account. In the end, this is cooking and everything is done 'to taste' so to speak. This is where science and art start to merge. You can always just take a teaspoon and measure one out on your scale.

I get that and agree. However, if his assumptions are easily available I'd like to have the correct assumptions is all.

By the way, I wish I was from an alternate universe sometimes myself

The intention was that it would be 1 tsp (5 grams) calcium chloride as the base line. If you wished to emphasize hops (as you would in many British styles) you would add 1 tsp of gypsum in addition to that original tsp of CaCl2.2H2O for a total of 1 tsp of each. But it then goes on to say for minerally beers (such as Burton ales) that you should double the salts (2 tsp of each).

Thanks AJ, really appreciate it.

Are you then assuming 5 grams per tsp of Gypsum as well?
