KNODOS 54mm Walnut Bottomless Portafilter for Breville — 3-Ear, 18–21g Basket Included

The KNODOS 54mm Walnut Bottomless Portafilter is the best-selling KNODOS portafilter and the upgrade most Breville owners make first. It removes the stock spout and gives you a clear view of the entire extraction from below the basket — channeling, uneven flow, and distribution issues become visible in real time. Built with Breville's 3-ear lugs, a solid walnut handle, and an 18–21g double shot basket. Fits Barista Express, Pro, Touch, Bambino Plus, Infuser, and Duo Temp Pro.

The Most Common Breville Upgrade

The stock Breville portafilter has a spout that divides and hides the espresso flow. A bottomless portafilter flips that — you see the extraction happen, identify problems while they are still in the cup, and adjust your grind, dose, or distribution to fix them.

3-Ear Lug for Breville 54mm Machines

Breville's 54mm machines use a unique 3-ear locking mechanism. This portafilter matches that design exactly. Does not fit Dual Boiler or Oracle (58mm, 2-ear).

18–21g Double Shot Basket

Ships with a stainless steel basket rated for 18–21 grams. Removable for cleaning or replacement with aftermarket precision baskets.

Walnut Handle

Solid walnut — the most popular handle choice in the KNODOS lineup. Warm mid-tone brown that matches KNODOS walnut tampers, distributors, and tamping stations for a coordinated setup.
