It works for me
I brew about once a month, and although I was making good beer, my OGs we're never as high as my beer software indicated it should be. I've tried this stuff for the last year with no other changes, and it has brought my OGs up 7 to 10 percent. I have never experienced any negative effects, and it has never resulted in a salty taste in my beers. But I would imagine its effectiveness would vary depending on one's particular water. I'm using well water in the central Rocky Mountains.

When switching to filtered tap water (rather than bottled), I realized PH matters. I'm not ready to learn chemistry, and I'm not trying to win awards... I'm just going for good beer. This stuff's my ONE addition, and it's terrific! I love this stuff.

Made beer taste like mineral water
I recently switched to AG and was obsessing about PH. My first beer I screwed up by adding 5.2 according to total water, rather than batch size. Though I got 91% efficiency, the beer was undrinkable, like mineral mud, and was dumped. The second beer, I used half the amount according to batch size (1/2 Tbls per 5 gal). This beer tasted like Perrier with a bit of beer mixed in and was at 88% efficiency. I kept it on the off hope that it will mellow over time, but it is not good now. After the 5.2 debacle, I decided tannins would be better and ignored the PH. This beer was decent, drinkable, but stalled out sweet (it was bigger, 1.085 -> 1.035) and I got 88% again. I just got a water report and my water is probably mineral deficient. I am going to adjust it manually and forget the 5.2 forever.FYI Na 22K 3Ca 29Mg 5Cl 23So4-S 7Total Alk 86

My water profile was all over the place.
My pH strips and pH meter showed I was close to 7.4? Variouse forms of specility malts and additives were a pain to do. I still have to tweak it a bit but 5.2 Mash ph Stabilizer made it easy and fool proof.

Perfect mash
Having VERY hard water, my efficiency was always low with light colored beers. This has changed my brewing to near perfect mash efficiency. I do not brew without it.

Good stuff
Mash water came down from Ph 7.2 to 5.2 nice and easy and my SG was spot on.

Serious boost in efficiency!
I have spectacularly hard water where I live and water chemistry confuses me. I bought this after seeing it on BTV and gave it a shot. WHOA! my OG readings were way higher than before. I usually have to mask 75 minutes to reach what they should be at 60, with this stuff I'm easily over target OG at 75 mins. It it kinda hard to gauge how well it will work for you.

I fly sparge. Should I use this in my sparge water as well as the mash?
A shopper on Jul 15, 2017
BEST ANSWER: I only use the stabilizer in my mash water with the other water treatments and sparge with plain RO or Spring water and get clean consistent results
Would this be useful for extract brewing? I usually brew extract with filtered water I buy form the super market, but if this could improve that process or allow me to just use tap water that would be great! thanks
J J on Jan 27, 2016
BEST ANSWER: This product is intended to help control mash pH. Since extract brewing does not involve this step, this product is not really needed. The boiling step of brewing is not particularly sensitive to varying pH. The only concern you should have with using tap water would be if the water contains something that would impart an off-flavor that wouldn't be boiled off. As a general rule, if your water tastes fine to drink straight, it's fine to use for extract brewing.
I make additions to my brewing water, depending on the type of beer I'm making. Can this be added even after changing the water profile with CacO3, salt, baking soda, etc...?
C A on Jul 4, 2016
BEST ANSWER: It is designed to adjust acidity and buffering so it can be used in that way. If you are already customizing your order, you should rely on salts or acids to hit the pH you want. This is the shotgun approach.
