IKAPE Variable Diameter Espresso Portafilter Basket

Why pick the IKAPE 58mm to 32mm step-down portafilter basket?

Traditional 58mm baskets, used with 58mm espresso machine brew heads, require a finer grind for the same 18g of coffee grounds to achieve a stable 9 bar extraction pressure. This can increase extraction yield and provide a more balanced flavor, but it can also easily extract bitter substances and off-flavors.

With a step-down portafilter basket, using the same 18 grams of coffee beans, or even less, the smaller basket diameter results in a thicker coffee puck, requiring a coarser grind. This is conducive to extracting sweeter espresso, while reducing the sharp flavors in the coffee beans. Overall, the resulting espresso is sweeter, more aromatic, and has a smoother mouthfeel.

How the IKAPE variable diameter basket works

A deeper basket builds a thicker puck. Water flow shifts through it. Pressure tightens up. Resistance grows. Extraction slows. Grounds meet water longer for even pulls. Channeling falls away. Shots stay steady.

IKAPE convex basket 58mm to 32mm

The IKAPE 58mm to 32mm convex basket uses CNC one-piece moulding. Its cone and trapezoid shape squeezes pressure tight and extra depth soaks coffee fully in pre-infusion.

The 18g espresso basket sits flush with the portafilter base

This IKAPE basket fits all 58mm portafilters. It sits level at the bottom with no tail. It works with every portafilter holder and tamper stand.

The differences between the two 58mm convex-shaped baskets

58mm with height 33mm-Can hold 16-20g of coffee beans. 58mm with height 38mm-Can hold 20-24g of coffee beans. The 38mm height option doesn't sit as tightly in the bottom of the portafilter.

Regardless of the type of coffee beans used, the grind size needs to be coarser than that used with conventional baskets. If no espresso is extracted during the brewing process, please adjust the grind size to be even coarser.
