The stock Gaggia Classic (and Classic Pro) portafilter basket is a common first upgrade — a bottomless “naked” portafilter shows extraction flaws instantly, and a precision basket improves shot consistency more than almost any other single accessory. These are real, currently sold portafilters and baskets fitted to the Gaggia Classic/Pro’s 58mm, diagonal-tab group head.

The picks, in detail

- Chrome-plated brass filter head
- Wooden handle
- Bottomless (naked) design
- Guaranteed correct fitment (official Gaggia part)
- Good heat retention from brass construction

A well-regarded third-party bottomless portafilter, also available in bakelite or rubber handle options.
- Bottomless design
- Walnut, bakelite, or rubber handle options
- Fits Gaggia 58mm group

- Popular, well-tested third-party option
- Must confirm the Gaggia-specific tab orientation when ordering
KNODOS 58mm Bottomless Portafilter
A stainless-steel-head, walnut-handled bottomless portafilter with broad compatibility across the Gaggia lineup, from Classic to Baby Twin.
- Stainless steel head
- Walnut handle
- Fits multiple Gaggia models
- Wide model compatibility beyond just the Classic
- Durable stainless steel construction
- Stainless retains less heat than a brass head

- Wood or plastic handle options

- Explicitly fit-tested for the diagonal-tab Gaggia group head

IMS Competition Filter Basket (68mm)
A precision basket upgrade for the stock or bottomless portafilter, with a hole pattern engineered for more even water flow through the puck.
- 68mm rim (Gaggia-specific sizing)
- Precision-drilled hole pattern
- Stainless steel
- Noticeably more even extraction than the stock Gaggia basket
- Forgiving of imperfect puck prep
- Must order the correct 68mm Gaggia-specific size, not the standard 70mm
IMS Baristapro Nanotech Precision Ridgeless Basket (18g)
A ridgeless, nanotech-coated precision basket sized for an 18g double shot, aimed at reducing puck-side channeling.
- Ridgeless design reduces channeling at the basket wall
- Nanotech coating
- 18g double-shot sizing
- Ridgeless wall design cuts down on edge channeling
- Precise, consistent hole geometry
- 18g sizing is fixed — a different basket is needed for other dose targets
Buying tips
- Always confirm the tab position — the Gaggia Classic/Pro uses diagonally placed locking tabs, unlike many machines that use side tabs, so a non-Gaggia-specific portafilter may lock in facing the wrong direction.
- A bottomless portafilter is a diagnostic tool as much as an upgrade — expect messier early shots while you learn to read the pour and dial in grind/dose.
- Pair a bottomless portafilter with a precision basket (IMS or similar) for the biggest single improvement in shot consistency — the portafilter body alone won’t fix channeling from a stock basket.
- Brass filter heads (like Gaggia’s own) hold heat slightly better than stainless for shot-to-shot temperature stability.
