Made by Five Star Chemicals. When added to the mash, this combination of buffer salts keeps the mash pH at 5.2—regardless of the pH of your brewing water. In our tests, we have achieved a noticeable increase in efficiency when mashing with Buffer 5.2.
- Borderline fraud Review by Scientist Brewer
It can "accidentally" work for a few people who are already very close to target pH. For the vast majority of brewers not taking a few minutes to read about how simple water chemistry can be, it's an abysmal failure.
This absolutely does not "lock in" a 5.2 pH. and if you add enough you'll buffer to ~5.7. Oops. At least it's good for keeping you under 6. Nevermind the sodium. (Posted on 8/5/12)

- Keeps your mash at 5.2, but... Review by natrix
It's a buffer solution, with a certain buffer capacity. If you dump it in to water with a pH of 8.0, you are asking too much of that buffer and it's not going to work. (Posted on 8/18/11)
- Made beer taste like mineral water Review by Sploit
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.

- Doesn't make better beer Review by JJL
- This may lock your pH in at 5.2, but it doesn't make better beer. It adds sodium, which does add a noticeable salty flavor to the beer. If the pH of your mash isn't right, this isn't going to fix your mash. It just moves the pH closer to 5.2. This isn't a substitute for having at least a minimum understanding of water chemistry.
