Master espresso puck prep with a dosing cup and tamper. Follow these steps to avoid channeling, ensure even extraction, and get café-quality shots at home.

Quick answer

Use a dosing cup to transfer grounds directly into the brew head without spillage, then tamp evenly with a tamper that matches your basket size for a level, firm puck.

Why dosing cup and tamper matter for puck prep

A consistent espresso puck is the foundation of balanced extraction. A dosing cup lets you grind directly into a container, then pour into the basket without losing grounds or creating uneven distribution. A tamper compresses the coffee into a uniform puck, preventing water from finding weak spots (channeling) that lead to sour or bitter shots.

The Dosing Cup & Tamper, Standard works with Flair GO, NEO Flex, and Classic Flair Espresso Makers. Its integrated design means the tamper fits the cup's opening, so you can level and tamp in one motion without switching tools.

Choosing the right tamper fit

A tamper that is too small leaves a gap along the basket wall, causing uneven pressure and side-channeling. A tamper that is too large won't fit at all. The Dosing Cup & Tamper, Standard is sized for standard brew heads, so it seats flush with the basket rim. If you use a different machine, check your basket diameter before buying.

Step-by-step: How to use a dosing cup and tamper

Grind into the dosing cup: Place the dosing cup under your grinder's chute and grind your dose directly into the cup. Aim for a fine, uniform grind—around the consistency of table salt for most espresso. Common mistake: grinding into the basket directly can cause uneven distribution. Using the cup lets you see and adjust the dose before transferring.
Level the grounds in the cup: Gently tap the side of the dosing cup to settle the grounds evenly. Then use a finger or a small tool to sweep away any mound, creating a flat surface level with the rim. Checkpoint: if the grounds are not level before tamping, you'll get a tilted puck and uneven extraction.
Transfer grounds to the brew head: Hold the dosing cup over the brew head basket and pour the grounds in one steady motion. Tap the cup lightly to release any stuck grounds. The cup's design minimizes spillage. Common mistake: pausing mid-pour can cause clumps. Pour quickly and evenly.
Tamp with the included tamper: Place the tamper on top of the grounds, keeping it perpendicular to the basket. Apply firm, even pressure—about 15-20 pounds of force—without twisting. The tamper should sit flush with the basket rim when done. Checkpoint: after tamping, the puck should feel firm and level. If it feels soft or uneven, redistribute and tamp again.
Wipe the basket rim and brew: Use a dry towel to wipe any coffee residue off the basket rim and the tamper. Then lock the brew head into your espresso maker and pull your shot immediately. Common mistake: leaving grounds on the rim can break the seal and cause water to leak around the puck.
