Description

10% concentration. Phosphoric acid is said to be tasteless while lactic in large quantities can potentially leave flavor. Being a lower conentration than the Lactic, it is slower to change the pH of your water and therefore more forgiving to use.

Good, neutral-flavored acid
My favorite acid to lower pH, because it has no noticeable residual taste.

Reduces PH with no flavor impact
I like to use Phosphoric acid to reduce the PH of my strike water. Easy to measure and I don’t have little powder piles in the bottom of the kettle.

lower the ph of your water
I started using this a couple of years ago. It (along with cal chl and a few other additions) makes it easy to hit the ph in the mash. Any mash, not just the dark beers.

Sadly this is the largest size bottle
Seems strange that you can order 100 of them, but not in a single bottle larger than this.

Lower Ph
Works great to lower mash water to 5.2 before sparging

Easier than Latic acid
Instead of the 88% Latic acid the 10% acid enabled me to dial in my mash ph to within .03, I be happy

Easy to bring pH down for mashing and sparging
4 ml is enough to bring my spare water of 8 gallons to 5.4 pH.
No influence on the beer flavor and easy to use as it is not full strength.
