A modern technique inspired by pour-over bloom — wet the puck, fully pause, let CO2 escape, then extract. Popularized in the Decent Espresso community.
The universal espresso profile. A constant 9 bar after a short pre-infusion — the standard of most espresso machines worldwide.
The classic Londinium lever profile — line-pressure pre-infusion followed by a natural pressure decline from the lever spring.
The legendary long low-pressure pre-infusion ramping up to 9 bar. The Slayer machine's signature control style made this a specialty coffee standard.
A modern low-pressure profile with a coarser grind. Short, fast, and balanced — without the need for long pre-infusion or extreme precision.
