The Coffee Catcha Dosing Funnel to suit 57-58mm Filter-holder
How it works
It is quite simple really... The Coffee Catcha acts as a funnel to stop the ground coffee from falling over the edge of the portafilter.
It is then used to scrape off the excess grind (as the barista would usually do with their finger).
Using the Coffee Catcha is also quite simple, trials have shown that it only takes a couple of days for the barista to get used to.
