xOverview
Meet the JUSTHERE 51mm Bottomless Portafilter, a versatile tool designed to fit a range of popular home espresso machines. With a 51mm diameter and a three-ear interface, this bottomless model is ready to integrate with CASABREWS CM5418, the 3700 Essential line, and Mr. Coffee espresso machines. Before you buy, confirm your original portafilter matches the 51mm size and the three-ear design with approximately 4mm prongs.
Constructed from food-grade stainless steel, this portafilter balances durability with a professional look. The surface is hand-polished for a sleek, reflective finish, and the handle uses a quality plastic that stays comfortable in the hand during extended use. The design also emphasizes heat retention, helping to maintain stable temperatures during extraction sessions.
Look and feel in daily use
In practice, the bottomless setup invites a clear view of the shot. You can observe the stream, color changes, and any irregular bands as the coffee emerges, which can guide tweaks to grind size, dose, and distribution. For many home baristas, this is a useful cue during routine tuning and experimentation.
- Compatibility: works with 51mm three-ear portafilters, including CASABREWS CM5418, 3700 Essential, and Mr. Coffee models.
- Included basket: a 51mm stainless steel filter basket with a 2-cup capacity (up to 18 g of ground coffee).
Practical brewing tips accompany the design. For best results, use freshly ground beans, adjust the grinder for consistent grind size, and employ a distribution and tamping routine that promotes even extraction. A light pre-heating of the machine and portafilter can help stabilize temperature during the pull.
Care and durability
Built to last, the portafilter’s stainless steel body resists wear and corrosion, while the polished exterior adds a professional touch to your setup. The ergonomic handle provides a secure grip, making manual control comfortable even during longer sessions. Cleaning is quick—simply rinse with warm water after use and wipe dry to prevent residue buildup.
- Maintenance: rinse after use, dry thoroughly, and avoid abrasive cleaners to preserve the finish.
- Notes: this model is not compatible with Delonghi machines; verify your machine’s matching 51mm, three-ear configuration before purchasing.
Caution: ensure your original portafilter matches the 51mm diameter and three-ear prong design (approximately 4mm thick) for best compatibility. Delonghi machines are not supported by this model.
