I'm sold. You had me at "crystal meth". Although I think my beers could be improved on with a little crack character added to it...

Seriously, that kind of scares me now that you say it has strong chemical smells. Did you notice any of this in your finished brews, or was it just in the strike water itself before the mash? I hit 71% on my second batch sparge yesterday, so if I can eventually hit 75% without the 5.2 buffer, I'll probably just forego using it, especially if it gives off funky odors.

No just the stuff itself smells. It doesnt affect the beer flavor at all. I stopped using it just because...no real reason, I just stopped using it. Im sure it works, but I didnt notice any difference in effecincy or anything.

My understanding of pH adjusters is that they are composed of salts, and the salts dissolved in water form ions, which give a lowering change to the pH. Also, trying to understand how Palmer explains pH and hardness, is that he links pH, and adjustment by salts, to the alkalinity of the water, which IIRC, is the available calcium (carbonate?) of some form.

All I know is I get confused every time I try to think of pH separate from alkalinity. Since I have a pool, a salt water, chlorine-ion generator type pool, and I'm generally half in the bag whenever I try to adjust the pool pH.

I have come to try to adjust pH in my pool with Muriatic acid, and think I want to use phosphoric acid (like the Brew/Pub) in my beer, rather than dump salts and minerals in it. The most direct way, in other words. Why add a bunch of minerals/salts to relatively soft well water? I just want to change the pH.

The standard in Europe now is to add lactic Acid to the mash to lower PH.

Alkaline sparge water will cause your mash PH to lower quicker but for anything other than pilsners or other light colored beers it shoud not matter. Odds are you will be done gathering your runnings before the PH drops enough to be a problem.

It's just a simple phosphate buffer I think. It may smell like chemicals but it won't hurt you and once it's diluted it will be undetectable.

I don't do a thing to adjust my pH. I've never even checked. It still comes out as great beer.

Adjustments are really only needed if you have screwy water with a high PH and are brewing light colored beers with said water.
