Zirkus Espresso Coffee Powder Dosing Cup 51/58mm Universal
Durable Anodized Aluminum Construction
Crafted from high-grade anodized aluminum, the cup boasts a scratch-resistant, corrosion-proof finish that stands up to daily use. The anodized coating prevents coffee grounds from sticking due to static, ensuring every last particle transfers to your portafilter and minimizing waste.
Universal 51/58mm Compatibility
Equipped with dual-size bottom slots that fit all standard 51mm, 54mm, and 58mm portafilters. No need to purchase multiple cups for different espresso setups—this all-in-one design adapts to your equipment seamlessly.
Unique Pull-to-Release Handle for Precision Dosing
Features an innovative pull-to-release mechanism that lets you drop coffee grounds directly and evenly into the portafilter basket. The controlled release eliminates messy spills and over-dosing, keeping your countertop clean and your coffee bed consistent.
Clump-Busting Shake Function for Even Extraction
Give the cup a quick shake before releasing the grounds to break up clumps and create a loose, uniform coffee bed. This simple step prevents channeling during extraction, unlocking richer, more balanced, and flavor-forward espresso shots every time.
Mess-Free & Waste-Reducing Design
Eliminates the frustration of scattered grounds and wasted beans. The cup’s enclosed structure collects every particle during grinding, while the targeted release ensures zero spillage—saving you money and keeping your coffee station tidy.

Frequently Asked Questions
Yes. This ZIRKUS dosing cup is designed with a dual-size structure for compatible 51mm and 58mm portafilters. Simply use the corresponding end of the cup when transferring coffee grounds into your filter basket.
No. This model is specifically designed for 51mm and 58mm portafilters and is not intended to fit 54mm Breville or Sage baskets directly. For a 54mm setup, we recommend using a dosing tool specifically designed for that basket size.
Yes. The dosing cup can be placed beneath a compatible grinder outlet to collect freshly ground coffee before transferring it into the portafilter. This can help keep your espresso preparation area cleaner and makes it easier to transfer a measured dose.
Yes. You can place the empty dosing cup on a coffee scale, tare the scale to zero, and then weigh either whole coffee beans or freshly ground coffee. This makes it useful for checking your dose before grinding or before transferring the grounds into the portafilter.

The dosing cup is designed to rest against the filter basket during coffee transfer rather than being forced into place. Place and remove it gently, and keep both contact surfaces free from coffee particles or other debris that could cause unnecessary scratching.
Remove any loose coffee grounds after each use and wash the cup with warm water and mild detergent when necessary. Dry it thoroughly before use or storage, especially before weighing coffee, as moisture can cause grounds to stick to the interior.
No. The dosing cup is designed for weighing, collecting and transferring coffee grounds. After transferring the grounds into the filter basket, distribute them evenly and tamp directly inside the portafilter basket using the correctly sized tamper.
