AMS (CRS)

How to use this product

This Kit Contains:-

500g of AMS

How much of the product to add

Some raw liquor can have an alkalinity of up to 200 and many brewers have a target range for treated liquor of between 70 and 100.

A suitable pH for mashing is 5.4.

A high mash pH can result in harsh beer flavour, poor extract due to reduced ß-amylase activity, reduced protein precipitation and risk of leaching polyphenols and lipids which will be detrimental to the beer.

 

The grid below shows the contribution of AMS additions to the chloride and sulphate content of the liquor and the amount of alkalinity reduction:-

AMS (ml/10L) .6 1.5 3 4.6 6 9.2 12.2 15.3 18.4
Chloride (ppm) 4.0 9.9 19.7 29.6 39.5 59.2 78.9 98.7 118.4
Sulphate (ppm) 5.4 13.6 27.2 40.8 54.4 81.6 108.8 136.1 163.3
Alkalinity -11 -28 -56 -84 -112 -168 -224 -280 -337

Where to add the product

The product can be added to either the cold or hot liquor tank and should be thoroughly mixed.

Time should be allowed to release the carbon dioxide produced by the neutralisation of the excess acid.

  1. Martin Crossley (verified owner) –

    The data sheet indicates that using this at a dose of 0.35ml/l reduces alkalinity by 64 mg/l while increasing chloride levels by 22.5 mg/l (ppm) and sulphates by 22.5 mg/l (ppm). In overall terms this corresponds to an acid ‘strength’ of 5%.

    i have chalky water so was using lactic acid to get the mash ph down for light bitters…then i tried this… bye bye sour flavour and hello lovely beer…x

  3. Mike Carrington (verified owner) –

    There doesn’t seem to be much information for brewers with very hard water who want to brew light beers. Then I came across this product which allows me to optimise hydrogencarbonate ion as well as sulfate and chloride ion concentrations. So much cheaper and better than boiling, deionising, or buying bottled water. My only negative is that you can’t buy the sulfuric acid and hydrochloric acids separately, so it isn’t possible to get exactly the desired sulfate to chloride ratio.
