Creamore Arcflow Series™ Convex Espresso Basket — 54mm / 58mm

A convex-bottom basket, available in 54mm and 58mm.

The Arcflow Series™ uses a convex arc bottom rather than the flat bottom found on most baskets. The curvature is subtle by design — it holds slightly more coffee than a flat basket of the same height and runs a little slower at identical settings. Coming from a flat basket, expect to spend a few shots re-dialling your grind. We would rather set that expectation than have you think your first pull was a defect.

Built from durable AISI 304 stainless steel with a ridgeless body for easier cleaning and smoother puck release.

About the finish

The waterdrop surface texture and the swirl mark on the base are visual design details, not flow features. They are etched into the metal and do not change how water moves through the puck. We call this out plainly because it is a fair question to ask.

Good to know

Ridgeless means there is no groove to trap grounds, but knock the puck out against a bar or knock box rather than into open air. If your portafilter spring is soft, the basket can sit loose — a ridgeless-spec spring fixes it.
