Grinding & redistribution funnel.
Designed to let the user re-distribute the grounds before tamping. Grind directly into the Blind Tumbler then give the grounds a quick stir in order to achieve a homogeneous puck. Once the grounds are re-distributed and the volume of the coffee is reduced to fit into your basket, place the Blind Tumbler on top of your portafilter, pull the plug, tamp and pull.
Made to fit both 49mm (Olympia Cremina, La Pavoni, etc.) and more standard 58mm baskets (La Marzocco, etc.). For the lidded version, please check out our Blind Shaker.
