It makes no attempt to model sparge acidification at all.



This is a work in progress. You should check the suggested water modifications with a trusted tool like Bru'n Water or Brewer's Friend . (Brewer's friend uses a different model for residual alkalinity than Bru'n Water, or this tool. The results from this tool should match Bru'n Water exactly. They should be close to Brewer's Friend, but probably will not match precisely.)It makes no attempt to model sparge acidification at all.

Target residual alkalinity [?] :



Residual Alkalinity (RA) combines the alkalinity of the water, the acid additions, as well as a model of how calcium and magnesium react with the grist to acidify the mash. If you don't know what RA value is appropriate for your recipe, refer to these charts from Kai , or this page from How to Brew.
