The Brew is Out There!  TECHNIQUE SHOW

Water is an important chemical - without it we wouldn't have beer! And for something that comprises so much of our beer, the chemistry we need to know to brew our best beer is Daunting - with a capital D. Drew sits down with Martin Brungard, creator of Bru'n Water, to demystify water chemistry and realize the functionality of Martin's mathmagical spreadsheet.

Sparge Water

Great episode, but I have a question for Martin. 

As a Brew'n Water user in a hard-water region (319 Bicarbonate//262 CaCO3), I am planning my first Czech Dark Pilsner and am planning on dilution of my hard water with distilled.  My question is this: Do I need to dilute both my mash water AND my sparge water?  In the Brew'n Water adjustment summary there is only dilution of the mash water.  If I do dilute my Sparge water, then the Sparge Water Acidification calculations go out of the window.

Thanks, Rich
