Key ideas in Espresso at Home
- Espresso requires high pressure to push water through the puck
- Old grounds create bitter, burnt flavors in the next shot
- The result is a concentrated liquid rather than a diluted cup
- A wet portafilter causes the new coffee grounds to clump and extract unevenly
- Hot water alone without pressure would just result in weak coffee
- The basket must be wiped clean and bone-dry before adding fresh coffee
- The fundamental mechanism that distinguishes espresso from regular drip coffee
- The importance of portafilter hygiene and dryness for a quality shot
- The double shot is the industry standard for most cafes
- Purging flushes out overheated water trapped in the machine
- Single shots are harder to extract consistently
- It removes stray coffee bits from the shower screen
- A double shot provides enough volume to balance with milk in lattes or cappuccinos
- This step ensures the water hitting the coffee is fresh and at the right temperature
- Recognizing the modern standard for espresso serving size
- The purpose of the group head purge in the workflow
