A portafilter that is both beautiful and practical made right here by Clive in Portland. Wood handle with a stainless steel basket.
Bottomless portafilters allow the barista to visually assess how evenly the coffee extracts through the filter basket. Imperfections in dosing and tamping are exposed if the coffee spurts out in different directions instead of straight down into the cup (known as channeling). A great learning tool for any barista, and beautiful to watch the espresso drip naturally into the shot glass.

58mm: fits any e61 group head, including LUCCA (excluding A53), Profitec, ECM, Lelit, Quick Mill, and Rocket machines (does not fit La Marzocco or Profitec Pro 800).
