Keep away from these frequent pre-infusion pitfalls that may spoil in any other case good pictures:

Mistake #1: Dashing the Course of

Downside: Leaping to full strain inside 2-3 seconds Consequence: Channeling, uneven extraction, bitter pictures Resolution: Permit minimal 5 seconds pre-infusion, longer for mild roasts

Mistake #2: Extreme Pre-Infusion Strain

Downside: Utilizing 4+ bars throughout pre-infusion part Consequence: Defeats the light saturation function Resolution: Preserve pre-infusion strain between 1-3 bars most

Mistake #3: One-Dimension-Suits-All Timing

Downside: Utilizing an identical pre-infusion for all coffees Consequence: Suboptimal extraction for various roast ranges Resolution: Develop roast-specific pre-infusion profiles

Mistake #4: Ignoring Visible Cues

Downside: Not watching preliminary water movement patterns
Consequence: Lacking early channeling indicators Resolution: Observe puck saturation and alter strain accordingly

Mistake #5: Inconsistent Approach

Downside: Various pre-infusion strain and timing between pictures Consequence: Unpredictable outcomes, more durable to dial in recipes Resolution: Apply constant strain software utilizing gauge suggestions
