Topic Synopsis
This unit covers barista skills including drink building techniques, equipment cleaning, product knowledge, and customer service. Learners demonstrate practical skills in a coffee shop environment.
Key Concepts & Core Principles
- Espresso extraction: The process of forcing hot water through finely-ground coffee under pressure (typically 9 bars) to produce a concentrated shot with crema. Key variables include dose, yield, time, and temperature.
- Milk texturing: Steaming milk to create microfoam by introducing air and heating to around 60-65°C. Proper technique ensures a silky, glossy texture suitable for latte art and consistent mouthfeel.
- Grind size and consistency: The fineness of coffee grounds directly affects extraction rate. A consistent grind (achieved with a burr grinder) is crucial for balanced flavour; too fine causes bitterness, too coarse results in sourness.
- Cleaning and maintenance: Daily backflushing, wiping steam wands, and regular descaling prevent build-up of coffee oils and milk residue, ensuring machine longevity and drink quality.
- Customer service and workflow: Efficiently taking orders, multitasking during rushes, and presenting drinks with attention to detail (e.g., clean cups, symmetrical art) are essential for customer satisfaction.
