Espresso extraction

Rapid Dialing-In Protocol: 5-Shot Method

Dialing in espresso typically wastes 10–20 grams of coffee as you adjust grind, dose, and tamp. This rapid protocol reduces waste to 5 grams while achieving balanced extraction in 5 shots or fewer.

Why Traditional Dialing In Wastes Beans

Most home baristas dial in by trial and error: pull a shot, taste it, adjust grind, repeat. This process typically requires 8–12 shots before achieving balanced flavor. At 18–20 grams per shot, that's 144–240 grams of wasted coffee.

The Rapid Dialing-In Protocol uses a systematic approach based on extraction time and taste feedback. Instead of random adjustments, each shot targets specific variables, reducing waste while building confidence in your technique. Understanding extraction science helps you make informed adjustments.

The 5-Shot Rapid Dialing Protocol

Before You Start: Setup

  • Weigh your dose: Use 18–20g for double baskets (adjust for your basket)
  • Prepare 5 portafilters: Pre-load all 5 with ground coffee to maintain consistency
  • Set a timer: You'll measure extraction time for each shot
  • Have a notebook: Record grind setting, extraction time, and taste for each shot
  • Warm your machine: Allow 15–20 minutes for temperature stabilization

Shot 1: Establish Baseline

Objective: Determine starting grind and extraction time.

  • Set grinder to medium (approximately 3.5 on a 1–10 scale)
  • Distribute grounds evenly in basket using WDT (Weiss Distribution Technique)
  • Tamp with firm, level pressure (approximately 30 lbs / 14 kg)
  • Start timer when water begins flowing
  • Stop timer when shot finishes (approximately 2 oz / 60 ml output)
  • Record extraction time and taste notes

Expected result: Extraction time 20–35 seconds. Taste will likely be sour or thin (under-extracted).

Shot 2: Adjust for Extraction Time

Objective: Achieve 25–30 second extraction time.

  • If Shot 1 ran under 22 seconds: Grind finer by 3–5 clicks
  • If Shot 1 ran 22–30 seconds: Keep grind the same
  • If Shot 1 ran over 30 seconds: Grind coarser by 3–5 clicks
  • Repeat distribution, tamping, and timing process
  • Record extraction time and taste

Expected result: Extraction time closer to 25–30 seconds. Taste may still be sour but less sharp.

Shot 3: Fine-Tune Grind

Objective: Achieve balanced flavor with 25–30 second extraction.

  • If Shot 2 tasted sour: Grind finer by 1–2 clicks
  • If Shot 2 tasted balanced: Keep grind the same
  • If Shot 2 tasted bitter: Grind coarser by 1–2 clicks
  • Repeat distribution, tamping, and timing
  • Record extraction time and taste

Expected result: Extraction time 25–30 seconds with balanced or nearly balanced flavor.

Shot 4: Verify Consistency

Objective: Confirm dialing is repeatable with identical preparation.

  • Use identical grind setting from Shot 3
  • Repeat distribution, tamping, and timing with same technique
  • Record extraction time and taste
  • If extraction time varies by more than 3 seconds: Adjust tamping technique or puck preparation
  • If taste is consistent: Proceed to Shot 5

Expected result: Extraction time within 1–2 seconds of Shot 3. Balanced flavor confirmed.

Shot 5: Final Confirmation

Objective: Confirm dialing is complete and repeatable.

  • Use identical grind setting and technique from Shot 4
  • Repeat distribution, tamping, and timing
  • Record extraction time and taste
  • If extraction time is 25–30 seconds and taste is balanced: Dialing is complete
  • If taste is still sour or bitter: Make one final micro-adjustment and pull a bonus 6th shot

Expected result: Extraction time 25–30 seconds with sweet, balanced flavor. Dialing complete.

Quick Reference: Decision Tree

Use this quick reference to guide adjustments:

  • Shot runs under 22 seconds: Grind finer 3–5 clicks
  • Shot runs 22–30 seconds but tastes sour: Grind finer 1–2 clicks
  • Shot runs 25–30 seconds and tastes balanced: Keep grind, move to verification
  • Shot runs 25–30 seconds but tastes bitter: Grind coarser 1–2 clicks
  • Shot runs over 35 seconds: Grind coarser 3–5 clicks

Common Dialing-In Mistakes to Avoid

Mistake 1: Making Large Grind Adjustments

Adjusting grinder by 10+ clicks between shots causes over-correction. Stick to 1–5 click adjustments based on taste and extraction time.

Mistake 2: Changing Multiple Variables at Once

If you adjust grind, dose, and tamp pressure simultaneously, you won't know which change affected the result. Change one variable per shot.

Mistake 3: Not Recording Data

Without notes, you'll forget which grind setting produced the best shot. Write down grind setting, extraction time, and taste for every shot.

Mistake 4: Inconsistent Puck Preparation

Varying tamping pressure or distribution between shots makes it impossible to isolate grind effects. Use WDT and consistent tamping for every shot.
