Kindlasti oled Youtube's või väga peenetes kohvikutes näinud, kuidas espresso "valgub" portafiltrisse, koondub kenasti üheks joaks ning voolab siis "hiiresabana" tassi... See on Open (ehk Bottomless) Portafilter. Ühesõnaga nüüd oled Sina ka jõudnud "järgmisele levelile" ja soovid teha tõelist espressokunsti? Ning samal ajal veenduda, et jahvatad õigesti ja pressid õigesti? Bottomless portafilter on siis täpselt Sinu jaoks!
You have surely seen it on YouTube, or in the very good cafés: the espresso beading up underneath the portafilter, gathering into a single stream and then running into the cup like a mouse's tail... That is an open, or bottomless, portafilter. So: you have reached the next level too, and you want to make real espresso art? And at the same time make sure you are grinding right and tamping right? Then the bottomless portafilter is exactly for you!
