Exam Focus
- Identify friction, elevation change, and variable restriction as resistance sources.
- Connect resistance to movement from keg to faucet.
- Know restriction is part of balancing draft flow.
What to know
Beer loses pressure as it travels through line, lift, and hardware resistance.
Syllabus detail
- Beer encounters resistance from draft-line friction, elevation change, and variable-resistance faucet devices when present.
Study task
Be ready to explain draft system resistance controls beer movement in the context of draft principles and apply it to a realistic Certified Cicerone® service, tasting, brewing, style, or pairing scenario.
Key Terms
- Draft system resistance
- Identify friction, elevation change, and variable restriction as resistance sources.
