Minerally And Soapy Taste
Caused two of my brews to go into the garbage because it left a minerally, salty and soapy taste afterwards. I added it according to the instructions, in a stout and a saison, with similar results. If you are thinking of tweaking you water chemistry, this is not the product to use. If your pH is way off, my recommendation is to look for individual salts to add to your water or mash instead of using a "catch all" like 5.2 stabilizer.

Does absolutely nothing! I have tested it with a PH meter an the results never change. This is just a waste of money.

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.

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.

Works for mash PH
This will put your mash PH at 5.2 but if you measure treated water at room temp it will be about 5.8 (as stated in another post) I've used this with no taste issues and have relatively high sodium content in my water. Use this and perfect sanitation, proper boil process, and fermentation control. Once you master that get a water test kit and adjust your water properly. Master the other things and you will make award winning beer. Water is the last thing to master unless it is just terrible. In that case buy water at the store.

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.
