Improve channeling and extraction with this common training tool that every barista swears by. The Bottomless Portafilter for espresso machines of all sizes is uniquely suited to monitor channeling and improve the extraction of any espresso coffees.
Bottomless portafilters are really easy to clean. A great benefit of using a bottomless, aside from easy cleaning, is that the clear view lets you examine your espresso's texture and color during the espresso extraction process. If you haven't seen the 'Tiger Stripes', that appear when good espresso is pulled through a bottomless portafilter – you are missing out.
