OK to Add AMS (CRS) to Mash to reduce ph?

[PeterAF]

I am interesting is using AMS to reduce the pH of my Mash if necessary

The information I’ve found so far says I can add to the cold or hot liquor tank but doesn’t mention adding to the Mash if that has a pH too high

Is it ok to add to Mash?

Or should I just be getting my water treatment right at the start and the correct Mash pH will follow from there?

Cheers

Pete

Welcome aboard Peter.
Ams is a water treatment.
It works to reduce the alkalinity.
Do you know what your current alkalinity is?

You normally treat your water before mashing.

Can you explain "if necessary"?
Hope you don't mind me asking, but it's making my mind bleed

If you mean, add it to the mash after using it to treat the water, then I don't see why not, in principle. But adding it to the mash and sparge liquor which then goes into the mash is not the same because the HCland the H2SO4 which make up AMS have been changed into their calcium salts in reducing the residual alkalinity of the water so it's not like adding acid directly to the mash. Would you calculate how much you need or jyst keep adding until the pH is right? How would you distribute it evenly throughout the mash? I'd be inclined to go with the pH and then add a bit more to the mash water if the next brew.

Rereading. Got it.

You shouldn't need to add it to the mash if you adjusted the water first. So "if necessary " shouldn't arise.

If you share a postcode of a shop or office near you, it should be easy to work out and give you a better answer.

You can add it to the mash, it's just a solution of Hydrochloric and Sulphuric Acid, although that's not really what it's designed for, and Lactic or Phosphoric may be a better option.

Using it as a liquor treatment.

Thanks for the above.
Previously I did the water treatment but I still ended up with a mash with pH too high. So, I'm pondering how to deal with that if it occurs again.
I've seen lactic acid suggested in such a case. I just wondered if I could manage to aviod buying it if I already have some AMS.
Hopefully, my water treatment will mean this doesn't come up

I will have a look.

The water websites do need a full postcode. Can you suggest one from a business or shop?

I use AMS to reduce alkalinity and Phosphoric acid to reduce pH. I use Brewfather software to calculate the amount of both acids based on my water profile, the grain bill and the target profile for the beer I’m brewing. I add the acids to mash and sparge water together with any other additions.

Had a look. AMS & DWB should work. What beer style do you typically make?

I have PM 'd you.
