Durable Metal Construction for Daily Espresso Use
ZIRKUS dosing tools are designed with durable metal materials for long-term espresso preparation. The solid structure helps maintain stability during grinding, dosing, and transferring coffee grounds.
Selected models feature a metal finish, smooth edges, and a compact lightweight design. The dosing funnel helps guide coffee grounds into the basket, while the dosing cup makes it easier to weigh, hold, and transfer ground coffee before extraction.
Reduce Mess and Improve Your Espresso Workflow
A dosing tool helps prevent coffee grounds from spilling over the edge of the portafilter basket. This is especially useful when grinding directly into the portafilter or using a WDT tool before tamping.
With a dosing funnel or dosing cup, you can keep more coffee grounds inside the basket, reduce waste, and make your puck preparation process cleaner. It is a simple tool, but it can make your espresso workflow feel much more organized.
How to Use Espresso Dosing Tools
Espresso dosing tools help you move coffee grounds into the portafilter more cleanly and with better control. Use the right method for your workflow:
Using a Dosing Funnel
- Choose the correct size
Select a 51mm, 54mm or 58mm funnel that matches your portafilter setup. - Place it on the basket
Set the funnel securely on the portafilter rim before grinding or transferring coffee. - Add the coffee grounds
Grind directly into the basket or pour in your measured dose. - Distribute with a WDT tool
Stir the grounds gently while the funnel helps prevent spills around the basket. - Remove the funnel and tamp
Lift the funnel straight up, clear any loose grounds from the rim and tamp evenly.
Using a Dosing Cup
- Weigh your coffee dose
Place the dosing cup on a scale and add the desired amount of ground coffee. - Position it over the portafilter
Align the cup opening with a compatible 51mm or 58mm portafilter. - Transfer the grounds
Turn the cup and portafilter together, then tap gently to move the coffee into the basket. - Level the coffee bed
Use a WDT tool or gentle distribution method to spread the grounds evenly. - Tamp and brew
Tamp the coffee, lock the portafilter into the machine and begin extraction.
Always check the product size and compatibility before use, and keep the dosing tool clean and completely dry between brewing sessions.
FAQS
What is the difference between a dosing funnel and a dosing cup?
A dosing funnel sits on top of the portafilter basket to help keep coffee grounds inside while grinding, distributing or using a WDT tool. A dosing cup holds the grounds separately so you can weigh and transfer them into the portafilter with less mess.
Should I choose a dosing funnel or a dosing cup?
Choose a dosing funnel if you grind directly into the portafilter or regularly use a WDT tool. Choose a dosing cup if you prefer to weigh coffee separately before transferring it into the basket. Our dosing cup is designed for compatible 51mm and 58mm portafilters.
Can I use a WDT tool with a dosing funnel?
Yes. A dosing funnel helps keep loose grounds inside the basket while you use a WDT tool, reducing spills around the rim. Make sure the funnel is fitted securely and provides enough space for the needles to move freely.
What size dosing funnel do I need?
Choose the funnel size that matches your portafilter or basket setup. ZIRKUS magnetic dosing funnels are available in 51mm, 54mm and 58mm options. Always check your machine model and basket dimensions before ordering.
Will a magnetic dosing funnel attach to every portafilter?
No. Magnetic attachment depends on the portafilter or basket material, rim design and magnet contact area. Even if the diameter is correct, the funnel may not attach securely to every model, so please check the compatibility information on the product page.
How should I clean a dosing funnel or dosing cup?
Rinse away loose coffee grounds with warm water and mild dish soap, then wipe with a soft cloth or sponge. Avoid abrasive cleaners that may damage the finish, and dry the tool completely before using or storing it.
