In the mash
Roasted malts are acidic, but their acidity plateaus: Troester's titrations found roughly 40 mEq/kg regardless of how dark the roast goes, and deLange's curves agree. That's why brewwtr predicts dark grists mash higher than color-scaled models suggest, and why stout brewers on soft water rarely need the baking soda that older calculators prescribe.

pH data: measured values compiled and cross-normalized in D.M. Riffe & M. Spencer, "A Homebrewing Perspective on Mash pH III" (2018), from measurements by Troester, deLange, Bies, Geurts, Walts, and Riffe-Spencer; multi-study means where several labs measured the same malt. Lot-to-lot variation of ±0.1 pH is normal. Malt DI pH, explained: what it is and how to measure your own →
