The full record
Infusion mash has its own catalogue entry with the detail this page summarises — causes, thresholds, related styles and evidence.
Infusion mash — Reach and hold a single conversion temperature by mixing grain with water at a calculated strike temperature, without further heating.
The traditional British method and the simplest. It works because modern, well-modified malt has already had much of its protein and cell-wall structure broken down during malting, so no lower-temperature rests are needed.
