Made to order to your spec — you choose the size and configuration.
This bottomless portafilter filter is the mesh insert that seats inside an espresso machine's portafilter and shapes every shot pulled across the bar. Stamped from food-grade 304 stainless steel, it resists corrosion from hot water and daily descaling, holds its shape under group-head pressure, and stands up to the shift-after-shift use a café or restaurant coffee station demands. The three-ear fitment locks it securely in place, and the bottomless (naked) design exposes the underside of the puck so a barista can read channeling and dial in extraction.
Three-ear seat for a secure, rattle-free fit in standard portafilters
Bottomless design for visible extraction and easier training
Available in 51 mm, 53 mm and 58 mm to match common group heads
Custom logo printing available for branded café programs

For home espresso enthusiasts, a bottomless portafilter basket turns dialing in a shot into something you can actually see. Watch the extraction stream directly from the underside of the puck to spot channeling, fix your tamp, and chase even, syrupy pours from your own machine. The 304 stainless steel build handles daily brewing and cleaning, and the 51, 53 and 58 mm options cover most home and prosumer group heads.

Frequently asked questions
How do I know whether to order 51, 53 or 58 mm?
Measure the basket seat in your existing portafilter, not the group head badge — the three sizes here match the common fitments, and 58 mm covers most commercial group heads while 51 and 53 mm suit smaller machines.
What does the bottomless design change behind the bar?
Removing the spout exposes the underside of the puck mid-shot, so a barista can see channeling as it happens and correct grind, dose or tamp. It doubles as a training tool for new staff.
Will the steel hold up to daily descaling and group-head pressure?
Food-grade 304 stainless steel is what it's stamped from, chosen because it resists corrosion from hot water and routine descaling and keeps its shape under pressure shift after shift.
Can these carry our café's logo?
Custom logo printing is available for branded café programs — send your artwork and the quantity you need with the order so the print can be set up alongside your size selection.
What holds the basket in place once it's seated?
A three-ear seat locks it into standard portafilters, which is what keeps it from rattling loose in the group during a busy service. Specify the size that matches your portafilter when ordering.
Is shipping included in the price?
For in-stock items — anything you can add to the cart — shipping is included in the listed price. For made-to-order items, delivery is either free (marked on the product page) or calculated when you place your order, based on destination and volume.
How long does delivery take?
In-stock items typically arrive within one to three weeks. Made-to-order items take three to six weeks, since we work directly with manufacturers and need time for production and logistics before shipping. Your assigned manager confirms a more precise estimate once your order is placed. Please note we can't be responsible for delays caused by customs clearance in the destination country.
Are import duties and taxes included?
In most cases, yes — we aim to ship Delivered Duty Paid (DDP), which means duties and import taxes are handled so you don't face extra charges on delivery. In rare cases we may ship Delivered Duty Unpaid (DDU), where you would settle import charges directly with the carrier — but only when agreed with you in advance.
Do your products come with a warranty?
Yes. Most of our equipment comes with a one-to-two-year manufacturer's warranty covering factory defects and technical faults under normal use; the specific term is stated on each product page. If a defect appears, we arrange a replacement or refund in line with our Exchange & Return Policy, and our team guides you through the claim step by step.
