Bottomless Portafilter - La Marzocco High quality bottomless portafilter to fit a La Marzocco coffee machine. Can be used as your main portafilter, or is also handy as a spare when other portafilters are being cleaned, or to use with a blind basket for backflushing. Why Are Bottomless Portafilters Great? Bottomless portafilters (those without a spout or bottom) can help you diagnose any issues with your espresso much faster as there's nowhere to hide during extraction. They also leave more space for your cup in smaller machines, which is particularly helpful when extracting into reusable takeaway cups. Got A Different Coffee Machine? We also have portafilters for most other machines available. If you can't find what you're looking for, please get in touch to see how we can help!
