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.

I see no label on the bottle. Dose this come with instructions?

BEST ANSWER: The bottle does come with a printed label that has the product information. The dosage rate will vary based on your application and water profile.

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.

Works as expected
Use this for my Milwaukee PH meter.

Great for pH adjustment
Better than Lactic acid for mash pH adjustment. 10 percent strength is perfect for my small batch brewing
