Exam Focus
- Explain pouring nitro beer as a service topic within Serving draft beer.
- Use specific evidence such as temperature, pressure, package condition, sanitation, equipment state, and observed service symptoms.
- Apply the topic to beer flavor, dispense quality, safety, and guest experience rather than repeating the heading alone.
Core knowledge
- Nitro service uses mixed gas and a restrictor faucet to create cascading bubbles and a dense head.
- The pour usually fills partway, settles for 1-2 minutes, then finishes down the middle.
- Common faults include wrong gas blend, warm beer, dirty restrictor plates, and serving before the cascade settles.
Study application
Diagnose nitro beer by gas, faucet, temperature, cleanliness, settle time, and expected low-CO2 texture.
