These portafilters are made from the Rancilio portafilters used on commercial machines. The basket is a commercial-quality La Marzocco triple basket, which can hold 19-21 grams of espresso, perfect for pulling a Portland style triple ristretto. This Bottomless Portafilter fits the Rancilio Silvia, as well as all our machines from Profitec, ECM, Rocket, and Quick Mill (except the Achille lever).
Bottomless portafilters allow the barista to visually assess how evenly the coffee extracts through the basket. Imperfections in dosing and tamping technique are exposed when the coffee spurts out in different directions instead of straight down into the cup. This is known as channeling. It can be a little messy to start with but is an invaluable learning tool for any espresso aficionado.
