Carafoam (Weyermann)
Crystal / caramel malt, typically 2.2 °L (5 EBC). Malt color varies by lot, treat listed values as typical and adjust to your malt analysis.

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.

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.
