Vienna (Weyermann)
Base malt, typically 3.5 °L (8 EBC). Malt color varies by lot, treat listed values as typical and adjust to your malt analysis.
| Type | Base malt |
|---|---|
| Typical color | 3.5 °L · 8 EBC |
| Distilled-water mash pH | 5.65 (measured, titrated) |
| Buffering (a1) | -32 mEq/kg per pH |
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.
