Start with basket fit
A tamper should match the basket closely enough to compress the coffee near the edges without binding. Nominal portafilter size does not always reveal the exact internal basket diameter, so confirm the manufacturer’s specification.
Useful tools and limits
| Tool | Useful for | Limit |
|---|---|---|
| Dosing funnel | Keeping grounds in basket | Does not distribute by itself |
| Needle distribution tool | Breaking clumps and evening density | Can create inconsistency if technique varies |
| Levelling tool | Repeatable surface | May compress only the top layer |
| Self-levelling tamper | Helping keep tamp level | Still needs correct basket fit |
Buy to solve a known problem
A scale, suitable grinder and well-fitting tamper usually matter before a collection of puck screens and distribution devices. Add tools when they improve a measured weakness in the routine.
Keep small needles and sharp tools stored safely and away from children.
