How to use this product

This Kit Contains:-

250g 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:-
