Key ideas in Barista Skills for the Perfect Cup
- The standard espresso ratio is 1:2
- Water naturally flows through gaps or thin spots in the coffee bed
- Liquid yield is measured by weight (grams), not volume
- Uneven distribution leads to 'channeling'
- Multiplying dry dose by the ratio determines the target output
- Channeling results in uneven extraction and poor flavor
- Applying the brew ratio to determine the correct liquid yield
- Understanding the cause of channeling and its effect on flavor
- A level, flat surface is more important than how hard you press
- 25-30 seconds is the standard benchmark for a balanced shot
- Tamping until the coffee resists further compression is sufficient
- Shots under 20 seconds are usually sour and under-extracted
- An angled tamp causes water to flow to one side of the basket
- Shots over 35 seconds are usually bitter and over-extracted
- Prioritizing a level tamp over physical force
- Recognizing the ideal time window for a standard espresso shot
