Milling

Syllabus Path

Milling cracks malt to expose endosperm while preserving husk structure for lautering. Predict lautering and flavor problems from crush quality before blaming mash or sparge technique.

  1. IV. Beer Ingredients and Brewing Processes
  2. B. Processes
  3. 1. Milling

Exam Focus

  • Explain milling as a brewing analysis topic within Processes.
  • Relate mill gap, roller configuration, kernel modification, husk preservation, flour, grits, and crush uniformity to the downstream mash and lauter.
  • Diagnose the trade-off between extraction and runoff performance, then recommend a crush adjustment supported by grist and equipment evidence.

Core knowledge

  • Milling cracks malt to expose endosperm while preserving husk structure for lautering.
  • Too coarse a crush reduces extract; too fine a crush can compact the bed, slow runoff, increase flour, and contribute husk-derived astringency.
  • Adjunct grains may require different mill gaps or pre-processing because kernel size and hardness vary.
