Grinder Components
- The grinder is used to grind roasted coffee beans.
- It's typically located next to the espresso machine.
- The hopper should be filled with beans before use.
- Grinder components include a hopper, collar, dosing chamber, tamper, loading bay, gate, and dosing lever.
Steam Wand Use
- The steam wand is used to heat and texture milk.
- It should be purged before and after use.
- Milk should be heated gradually, using circular motion.
Group Head Function
- The group head is part of the espresso machine.
- It dispenses water for espresso.
- It includes a shower screen, brass plate, drainage pipes, and drip tray.

Group Handle Use
- Ground coffee is dispensed into a filter basket within the group handle.
- A single group handle holds one dose of coffee for one shot of espresso.
- A double group handle holds two doses of coffee for two shots of espresso/ristretto.
Tamper Function
- A tamper is used to compact coffee grounds in a basket.
