Taste mapping by profile style
How different espresso profile styles—pressure, flow, and temperature manipulations—map to sensory outcomes in the cup.
Light roasts
Temperature profiling and surfing
How temperature profiling and temperature surfing influence espresso extraction, especially across roast levels and machine types.
Flow-regulated extractions
How flow-regulated espresso extractions differ from pressure-based methods, and how they influence consistency, puck integrity, and flavor.
Declining vs flat pressure profiles
The differences between declining and flat pressure profiles in espresso, and how they influence extraction dynamics and flavor outcomes.
Preinfusion timing and pressure
How preinfusion timing and pressure influence espresso extraction, flow dynamics, and final cup quality.
Allonge and turbo shot concepts
Two modern espresso styles—allongé and turbo shot—their brewing parameters, taste profiles, and why baristas experiment with them.
