IKAPE Convex Variable Basket 58mm 18-20g

Why Choose the iKAPE 58mm to 32mm Step-Down Portafilter Basket？

Traditional 58mm baskets, used with 58mm espresso machine brew heads, require a finer grind to achieve a stable 9 bar extraction pressure with the same 18g of coffee grounds. 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

When the basket is deeper, the coffee puck is thicker, and the water flow through the coffee puck changes. The water pressure becomes more concentrated, the water flow resistance increases, and the extraction slows down. This results in longer contact time between the coffee grounds and water, leading to more uniform extraction.  Simultaneously, channeling is reduced, and the consistency of the espresso is higher.

iKAPE Convex Basket 58mm to 32mm

The IKAPE 58mm to 32mm convex basketr portafilter basket is manufactured using CNC integrated molding, resulting in a conical and trapezoidal shape that creates a tighter pressure space. The deeper depth allows for thorough pre-infusion during the pre-infusion stage.

The 18-gram Espresso Basket Sits Flush with the Bottom of the Portafilter

The IKAPE reducer basket is compatible with all 58mm portafilters and sits flush with the bottom of the portafilter, without a protruding tail. It is compatible with all portafilter holders and coffee tamper stations

Espresso Can Be Extracted Without Using Coffee Tamper for Pressing

Thanks to its tapered shape, the IKAPE variable diameter basket facilitates pressure build-up. Therefore, with the appropriate grind size, espresso can be extracted without using a coffee tamper. Of course, if a coffee tamper is desired, the grind size can be adjusted to be coarser, and the coffee grounds can be leveled with a distributor before tamping.

The complete process:
① Adjust grinder setting → Use WDT tool → Use distributor → Extract espresso
② Adjust grinder setting → Use WDT tool → Use distributor → Use coffee tamper → Extract espresso
In these processes, no additional accessories are needed; simply use your regular coffee tools.

The differences between the two 58mm convex-shaped baskets

58mm with height 33mm-Can hold 16-18g of coffee beans

58mm with height 38mm-Can hold 18-22g of coffee beans（Due to limited stock and the limitations of the marking process, some stock of 38mm height baskets does not have a logo on the side, but the bottom still retains the “IK” pattern.）

Apart from that, all other features are the same. Please look for the following authentic logo
