5.2 is a proprietary blend of food-grade phosphate buffers (similar to brewer’s salts) that will lock in your mash and kettle water at a pH of 5.2 regardless of the starting pH of your water. 5.2 is safe for your mash and WILL NOT add any flavors to your beer. 5.2 will provide consistency of pH in any water conditions, but the most significant gains will be obtained if you are brewing in hard water. Use 5.2 Mash Stabilizer to optimize your enzymatic activity in your malt, help clarify your wort, and achieve a more consistent hop utilization. Use 1/3 oz. per 5 gallons of water.

Must have for All Grain Brewing
Once I realized that my pH had to be 5.2 and I started testing the pH I realized I was no where I needed to be. I started using the 5.2 pH stablizer and it works wonders! It is also so easy to use, just get your strike water up to temp, put it in your mash tun, add 1 tsb for 5 gallons of water and your good to go. Once I started using this I notices my beers comming out 10x better.

Results are in the numbers
I brew with the Grainfather and I've had problems reaching my target numbers ever since I got it. My mash efficiency stank. When I wanted an OG of 1.055, I got 1.044. When I wanted 1.040, I got 1.029. I tried single, 2- & 3-step mashing, double milling the grist, adding rice hulls, extending the mash duration to 90 min all to no avail ... until I tried this product. The first time I tried 52 pH I hit my numbers exactly! I wanted a preboil SG of 1.044 & got 1.046 and an OG of 1.055 and got 1.054. I highly recommend this product!

Way better than bottled
I use to use gallon jugs for my brew but after finding this little Gem, I just use my tap water and this balances everything out with no hassle at all. I noticed a big difference between the tap and after. My Pale Ale's turn out better than when I was using distilled jugs.

Great for your mash if you have hard water
I have used this with success for over a year. I have used pH test strips to verify the pH, and it was spot on.

Use Everytime
I've reviewed my water reports and have hard water. I purchased this and began using in in all of my ales. There are no off flavors and it seems to increase the sharpness of brew!

Didn't adjust the pH like I'd hoped
I followed the directions but it didn't move the pH to 5.2, and I didn't want to add more in case it would mess up the beer. I've been reading Palmer's Water book that I bought from Midwest and it's a complex subject. I'm going to use a pH meter and measure out the additives by hand, from Acid, to Calcium, to Gypsum.

Tried twice
I followed the directions and measured out the correct amount. I have a pH meter and it didn't bring the wort pH to 5.2. It didn't seem to have the desired effect.

works great
I was having difficulty getting proper starch conversion and this helped get me in the right pH range and conversion went quickly.
