Exam Focus
- Explain water as a brewing analysis topic within Ingredients.
- Relate source water, alkalinity, hardness, calcium, magnesium, sulfate, chloride, sodium, bicarbonate, and treatment to mash and flavor outcomes.
- Build a water-adjustment rationale around mash pH, yeast health, bitterness, malt expression, and style without copying a city profile uncritically.
Core knowledge
- Water affects mash pH, enzyme performance, hop bitterness perception, malt roundness, yeast health, and finished-beer flavor.
- Calcium supports mash performance and yeast flocculation; chloride can round malt and body; sulfate can sharpen hop bitterness; bicarbonate raises alkalinity and can suit darker grists.
- Chlorine or chloramine can form chlorophenolic off flavors and should be removed before brewing.
Study application
Connect a water profile to style target and process outcome rather than naming brewing cities only.
Key Terms
- Chlorine or chloramine
- Chlorine or chloramine can form chlorophenolic off flavors and should be removed before brewing.
