P 7.05 – Recap and Glossary

Please sign up for the course before starting the lesson.

Recap

  • Coffee equipment should be soaked in a dedicated coffee cleaning soap at least once per day.
  • Cleaning chemicals need to be dosed in accordance with the manufacturer’s recommendations.
  • For preheating and ensuring clean-tasting batches, filter baskets/funnels and vacuum flasks need to be rinsed with a reduced-size brew cycle between each batch — approx 25% of your usual batch size.
  • Efficiency and quality standards can be tested using a baseline scoresheet. A fresh batch brew can be readied in 2 minutes.
  • We recommend you use the grinding and portioning time to rinse the brewer and flask.
  • Hand brews are more labour intensive and require around 2 minutes per brew up until the end of the dilution phase.
  • Costing needs to reflect the staff cost per portion and ingredient cost.
  • Make use of your brew-price calculator to manage sale prices effectively.
