Key ideas in Perfecting the Barista Express
- The 54mm basket is narrower and deeper than commercial 58mm versions
- The BBE timer doesn't account for changes in grind size or resistance
- Overfilling prevents the shower screen from distributing water evenly
- Crema volume is deceptive and changes as beans age
- An 18g dose leaves the ideal 'headspace' for the puck to expand
- Stopping the shot manually on a scale ensures a precise yield weight
- Why the 18-gram dose is the mechanical sweet spot for the BBE's 54mm basket
- The necessity of manual yield control over the BBE's internal timer
- The 1:2 ratio means the liquid weight is double the dry dose
- 36g of liquid is the traditional target for an 18g dose
- The gauge reflects the resistance the water meets inside the puck
- Low pressure usually indicates the grind is too coarse for the BBE
- Using the BBE pressure gauge to diagnose puck prep issues
- Fresh beans contain more CO2 which creates more natural resistance
- Applying the 1:2 ratio to calculate a target yield
- As beans age and lose gas, water flows through the puck faster
