Puk prep is critically important for consistently good espresso. If your puck prep is ineffective, not even the best espresso machine in the world will deliver results. What you trying to avoid is uneven extraction, which can be caused by uneven distribution and channelling. Channelling is when water finds a weak spot in the puck, attracting more water to pass through that channel than the rest of the coffee bed. The result is a mix of desirable and undesirable flavours rather than a harmonious delicious espresso. For the ideal puck, you need:
- Consistent grinds from a good quality espresso grinder.
- Even distribution of coffee in the portafilter. This is where the WDT tool comes in, and,
- A level tamp. Using a self-levelling calibrated tamper like the Timemore Impulse Tamper, ensures you tamp like a champ every time.
Manual versus automatic WDT:
| Feature | Manual WDT | Automatic WDT |
|---|---|---|
| Higher Consistency | Random speed and motion depending on user. | Calibrated motion designed for perfect distribution every time. |
| Higher Repeatability | Results will vary depending on technique. | Fixed program repeated every time. |
| Efficiency / Speed | Disrupts work flow. | Easy and automatic. |
| Cleanliness | Messy spills. | Perfectly clean every time. |
