In the mash

Crystal malts are kilned wet, which caramelizes sugars and generates acidity roughly in proportion to color. In the mash they pull pH downward, a 10% addition of a mid-color crystal typically drops the mash 0.05–0.1 pH, which is why caramel-forward grists often need little or no added acid.
