ABOUT US - Crema Coffee Products was born to develop the best tools possible to make the best espresso and to help elevate your home espresso experience. We believe making your favorite coffee drink should be a labor of love and something you love to enjoy and share with others. The Game Changer for Perfect Extraction Bottomless (aka naked) portafilters are an essential tool for identifying and correcting extraction problems that cannot be seen with standard spouted portafilters. Plus, who doesn't love seeing those beautiful tiger stripes? NEW FEATURE UPDATE: We've modified our bottomless portafilters to now include a 15° tilt to the handle, providing improved grip and ergonomics. This 54mm bottomless portafilter was designed to work with the Breville/Sage Barista Express, Barista Express Impress, Barista Pro, Barista Touch, Bambino, Bambino Plus, Infuser and Duo-Temp Pro. Double-shot, single wall filter basket included. PLEASE NOTE: Channeling and spurting can be very messy, but are EXTREMELY common. This is not a defect of the portafilter itself, but instead is your coffee telling you that there's room for improvement in your preparation process (grind size, tamping, distribution, etc.).
