* Required Fields



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.

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

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!

Seems to do its job
Good price. Does the job

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.

Changed the taste of the beer
I followed directions and was careful measuring. I didn't care for the taste of the beer afterwards. I used pH strips and it didn't get the pH to where it was supposed to be.

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.

For hard water
I have hard water and came upon this in the course of my research. I tried it but it didn't lower the pH. I added more and still more but it didn't work right. I was not a fan of the beer and wont use it again. Instead I'll use acid malt.

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!

Doesn't work
I have a pH meter and used this and it did not adjust the pH to where it needed to be. It could be my imagination but the beer didn't taste as good when i used this (I've used it twice). I won't use it again.

No effect
I used a pH meter on a cooled sample of wort, took a reading. Added the Mash Stabilizer and the pH didn't drop. I ended up mashing with the pH a little higher than I'd like it, but the beer was ok anyway. I will use an ounce of acidulated malt next time to drop the pH 0.2
