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.

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.

Adds unnecessary sodium
5.2 is a sodium phosphate salt so it adds a whole buncha sodium to your beer - when paired with a high level of sulfates it definitely makes for a less than good beer. You're better off not messing with your water or learning a tertiary amount of information about water. This is not good stuff - I've made award winning beers with it, but I'm the first to say that that was lucky.http://www.homebrewersassociation.org/forum/index.php?topic=1125.0

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

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...?

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.
