Espresso Dosing Cup 51/54/58mm – Inverted Aroma Cup for Precise Dosing

Dosing directly from grinder to portafilter works — but it costs you aroma, creates mess, and makes accurate weighing difficult. The Coffee Dosing Cup from COFFEECONCEPT adds one step that improves three things simultaneously: it traps volatile aromatics, eliminates counter scatter, and gives you a stable platform for precise gram-level dosing before transferring to the basket.

The Dosing Cup Workflow

Instead of grinding directly into the portafilter, you grind into the dosing cup, weigh it on your scale, then invert it onto the portafilter basket. The cup inverts cleanly, deposits grounds uniformly, and — when used as an aroma cup — traps the first 30–60 seconds of volatile compounds that would otherwise dissipate into the air.

This matters more than it sounds: coffee's most delicate aromatic compounds are the first to escape after grinding. Trapping them in the cup and releasing them directly into the basket means more of those compounds end up in your shot, not on your counter.

Key Features

Inverted Aroma Cup Design

The cup seals against the portafilter basket edge when inverted, briefly trapping aromatics against the grounds before they transfer. This is the same principle used by professional single-dose workflows where every gram of aroma matters.

Universal Compatibility: 51/54/58mm

Designed to fit snugly over standard portafilter basket diameters. Compatible with 51mm (DeLonghi Dedica), 54mm (Breville Barista Express), and 58mm (most prosumer machines) baskets. Check your basket diameter before selecting.

Eliminates Dosing Mess

The cup lip catches stray grounds during grinding. No more chasing flyaway particles across the counter. Transfer is clean and contained — tip the cup over the basket and the grounds fall as a compact, pre-shaped bed ready for distribution.

Scale-Ready Flat Base

The flat, stable base sits perfectly on a kitchen scale for accurate pre-dose weighing. Dial in your recipe (e.g., 18g in → 36g out) with consistency, then transfer confirmed weight directly to the basket.

How to Use

1. Place dosing cup under your grinder's chute
2. Grind your dose
3. Set cup on scale — verify weight, adjust if needed
4. Optional: wait 30 seconds with cup upright to let CO₂ degas slightly
5. Invert cup onto portafilter basket — press gently to seal, then lift straight up
6. Distribute with WDT tool, tamp, and pull your shot

Dosing Cup vs. Dosing Ring — What's the Difference?

Compatible Grinders

Works with all grinders that produce a bottom-exit stream: Niche Zero, Fellow Ode, DF64, Baratza Vario, Eureka Mignon, and most burr grinders with adjustable chutes. Not designed for grinders with built-in dosing hoppers where the portafilter locks directly.

Frequently Asked Questions

Does the dosing cup work with static-prone grinders?

It reduces scatter by containing grounds, but it doesn't eliminate static charges. For heavily static-prone setups, pair with our Magnetic Anti-Static Dosing Ring for complete control.

What material is the dosing cup made from?

Food-grade stainless steel or BPA-free material depending on variant — safe for contact with ground coffee. Easy to rinse clean between sessions.

Does it work for filter coffee dosing too?

Yes. The cup works for any grind size, including filter and pour-over, where pre-dose weighing is part of the workflow.
