Learn a clean, repeatable dosing routine with the Lelit Coffee Slide 58mm portafilter, from grind catch to tamp, and avoid the most common mess-making mistakes.

Quick answer

Use the Lelit Coffee Slide portafilter as your single dosing station: lock in the right IMS basket, grind directly into it with a dosing funnel, level and tamp, then rely on the slide spout to keep the basket off the worktop between shots.

Why the basket choice changes your dosing routine

The Lelit Coffee Slide set includes four stainless steel filters made with IMS: 9–11 g, 14–18 g, 18–21 g and a blind basket. Each dose range needs a different grind setting and fill level, so decide which basket matches your coffee dose before you start grinding. A 14–18 g basket filled with 20 g will overflow no matter how careful you are, and the mess will look like a technique problem when it is really a basket mismatch.

Where the slide spout helps and where it does not

The Coffee Slide spout is shaped to keep the portafilter from resting directly on the worktop, which reduces the chance of picking up moisture or stray grounds between shots. It does not replace a dosing funnel, and it does not level the bed for you. Treat it as a resting and handling feature, not a mess-prevention shortcut during grinding.

Step-by-step mess-free dosing with the Lelit Coffee Slide

Pick the basket that matches your dose: Weigh your intended dry dose, then install the IMS filter whose range covers it: 9–11 g, 14–18 g or 18–21 g. Keep the blind basket out of the dosing rotation. If your dose sits at the top of a range, expect a fuller basket and slower leveling.
Set the portafilter on a stable, dry surface: Rest the Lelit Coffee Slide on its spout so the basket stays clear of the worktop, and wipe the rim of the basket dry before grinding. A damp rim makes grounds cling and scatter when you lift the funnel.
Grind into the basket with a dosing funnel in place: Lock a 58mm dosing funnel onto the basket, grind your weighed dose, then give the portafilter one firm tap on the counter to settle the mound before removing the funnel. Remove the funnel only after the grounds have settled; lifting it early is the most common cause of spillage.
Level and tamp without pressing on the spout: Distribute the bed evenly, then tamp straight down using the basket as your guide. The brown handle is shaped to make pressing comfortable, but keep the force over the basket, not the handle. A level tamp matters more than a hard one; check that the puck sits below the basket rim.
Knock out and reset the station: After the shot, knock the puck into a knock box, rinse and dry the basket, and return the portafilter to its slide-spout rest. A dry basket at the start of the next dose prevents clumping and stray grounds.
