Green Cuisine jars are reported to be a perfect solution for those with 49mm gear to replace the supplied 58mm cup. I can't find a retailer in the US.

I wrote Slow Pour to inquire directly via the website. The answer came in the form of a bait and switch that subscribed me to the Goodies Department sales spam list.

Has anyone found a cunning item that does the trick?

My Sapaziale has a 53mm PF so the supplied dosing cup doesnt fit.
I grind directly into the PF using a funnel to avoid spillage. I do WDT with the funnel in place, remove the funnel & tamp. Works quite well.

I am using this exact workaround. It works for me, but will baffle newbie family members who like to pull their own shots when they visit.

I found these candle cups at the dollar store which works very well for my 49mm portalfilter. I had to clean it up.
