In the mash

Base malts form the backbone of the grist and largely set the mash pH floor: in distilled water most land between 5.5 and 5.8, and — as Troester’s 2009 measurements showed — color is only a loose predictor of where a given lot falls. On low-alkalinity water a pale base-malt grist usually needs only a small acid addition to reach the 5.3–5.4 range.

pH data: Kai Troester, “The effect of brewing water and grist composition on the pH of the mash” (2009, braukaiser.com). Lot-to-lot variation of ±0.1 pH is normal.
