Exam Focus

  • Explain protect beer from light as a service topic within Beer storage.
  • Connect light wavelength, package color, exposure time, and hop-derived precursors to lightstruck aroma risk.
  • Evaluate retail display and service practices for bottles, cans, and poured beer, then choose controls that reduce exposure before skunky character develops.

Core knowledge

  • Lightstruck character forms when light reacts with hop-derived compounds, creating skunky aroma that can appear within minutes.
  • Risk rises under sunlight, fluorescent light, and many LEDs, especially in clear or green glass; brown glass helps and cans or closed cases protect best.
  • Display and cooler choices should keep vulnerable packages away from bright light rather than relying on cold storage alone.
