Single-dose workflows

What is Single-Dosing?

• Loading only the exact amount of beans per brew into the grinder.
• No hopper storage—grinder runs empty between uses.
• Prioritizes freshness, accuracy, and retention control.

Advantages

• Freshness: Beans stay sealed until use.
• Precision: Exact weight-in = weight-out workflow.
• Flexibility: Easy to switch between coffees.
• Retention Control: Less risk of old coffee mixing in.

Workflow Steps

1. Weigh Dose: Measure beans to recipe target (e.g., 18.0 g).
2. RDT (Optional): Lightly mist beans to reduce static.
3. Load & Grind: Place beans directly into burr chamber.
4. Purge/Blow-Out: Use bellows or puffer to clear retained grounds.
5. Weigh Output: Confirm yield matches input.

Challenges

• Some grinders are designed for hopper-fed workflow, causing popcorning (beans bouncing, leading to uneven feed).
• Retention may still occur in chute without bellows.
• Grind speed may be slower compared to loaded hoppers.

Optimization Tools

• Bellows Mods: Clear retained grounds.
• Weight-In/Weight-Out Logging: Improves recipe repeatability.
• Single-Dose Conversions: Aftermarket hoppers and chutes designed for minimal retention.
• Anti-Popcorning Devices: Mesh or weights to keep beans feeding evenly.

Use Cases

• Home Brewing: Popular for enthusiasts switching between coffees.
• Specialty Cafés: Useful on sample bars or for rare coffees.
• Production Settings: Less common due to slower workflow, but useful for QC.

Summary

Single-dose workflows maximize precision, flexibility, and freshness by weighing beans individually and clearing retention after every grind. With the right tools—bellows, RDT, and anti-popcorning devices—single-dosing can deliver consistent, clean extractions tailored to each coffee.
