The Single-Origin Dial-In Blueprint: Pressure Profiles

Light Roasts: Extended Pre-Infusion

Light roasts are dense and notoriously tough to extract. To avoid sour, grassy shots: Pre-Infusion: 8–10 seconds at 2 bars to fully saturate the grounds and build heat. Peak Pressure: Ramp smoothly to 9 bars. Taper: As the shot ends, slowly decline to 5 bars to prevent late-shot channel extraction.

Medium Roasts: The Balanced Classic

Medium roasts balance vibrant acidity with sweet, caramel notes. Pre-Infusion: 5 seconds at 2–3 bars. Peak Pressure: Hold a steady 7 to 8 bars through the heart of the pull. Taper: Drop to 6 bars during the final third of the shot for a smooth, velvety body.

Dark Roasts: Low Pressure, Soft Touch

Dark roasts extract easily and can quickly turn bitter if hit with high pressure. Pre-Infusion: Quick 2-second soak. Peak Pressure: Cap your maximum pressure at 5 to 6 bars.

If you are exploring off-grid trails with no electricity, pure manual pressing using the

gives you unlimited brewing capabilities to execute these exact profiles anywhere.
