Step-by-Step Iced Espresso Preparation
Pre-Extraction Phase
- Pre-chill vessel: Place serving glass in freezer for 5 minutes
- Prepare ice: Measure ice into pre-chilled glass (100g for double shot)
- Purge machine: Run 2-3 seconds of water through group head
- Dose coffee: Weigh 18-20g coffee into portafilter
- Distribute grounds: Level coffee bed with distribution tool or finger
- Tamp evenly: Apply 15-20kg pressure with level tamp
- Inspect puck: Verify smooth, level coffee surface
Extraction Phase
- Lock portafilter: Insert into group head with firm pressure
- Position vessel: Place ice-filled glass under spouts immediately
- Start extraction: Activate pump and begin timer simultaneously
- Monitor flow: First drops should appear at 6-8 seconds
- Observe color: Stream should transition from dark to blonde
- Target yield: Stop extraction at 60ml for double shot
- Time check: Extraction should complete in 25-30 seconds
Post-Extraction Phase
- Immediate chilling: Swirl glass gently to distribute espresso over ice
- Monitor temperature: Espresso should cool below 10°C within 10 seconds
- Add ice if needed: Top up with additional ice to maintain cold
- Serve instantly: Present immediately for optimal flavor
- Consume quickly: Iced espresso best enjoyed within 2-3 minutes
Chilling Method Comparison

Bean Selection for Iced Espresso
Optimal Roast Profiles
- Medium Roast: Balanced acidity, preserves origin character
- Medium-Dark Roast: Chocolate notes, caramel sweetness

- Sumatran: Earthy, full-bodied, low acidity
Extraction Parameter Troubleshooting
❌ Common Issues & Solutions
| Problem | Possible Cause | Solution |
|---|---|---|
| Too fast (<20s) | Grind too coarse, insufficient dose | Finer grind or increase dose 1g |
| Too slow (>35s) | Grind too fine, too much dose | Coarser grind or reduce dose 1g |
| Sour taste | Under-extraction, low temperature | Extend time or increase temp |
| Bitter taste | Over-extraction, burnt notes | Shorten time, cooler water |
| Channeling | Uneven tamp, poor distribution | Improve technique, WDT tool |
