IKAPE | IKAPE Variable Diameter Espresso Portafilter Convex Basket 58mm BlackPrecision High Extraction for 58mm Bottomless Portafilter

IKAPE Variable Diameter Espresso Portafilter Convex Basket 58mm Black,Precision High Extraction for 58mm Bottomless PortafilterHow Convex 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.Advanced Ceramic Carbon Baked Coating: Built for the GrindSay goodbye to fading colors and scratches. Our proprietary Ceramic Carbon Baked Coating is applied under ultra-high temperatures, fusion-bonding a food-safe ceramic barrier onto the precision stainless steel base. It delivers a stunning, premium matte-black texture that resists scratches from WDT needles, stands up to 300°C thermal shocks, and guarantees zero chemical leaching.Thicker Coffee Puck, Enhanced SweetnessTraditional flat baskets spread coffee thin, forcing you to grind too fine and risk channeling. IKAPE’s tapered 32mm bottom concentrates your 18g dose into a deeper, thicker coffee bed. This optimal geometry regulates water flow naturally, eliminating channeling and drawing out maximum syrup-like sweetness and rich body.CNC Precision & Conical SynergyCrafted via integrated CNC molding, the conical-trapezoidal interior perfectly pairs with the ceramic finish to ensure uniform pre-infusion. Water saturates every grain consistently, turning even high-acidity light roasts into smooth, balanced, and vibrant espresso.Hydrophobic & Easy-Clean: Say Goodbye to Coffee StainsThanks to the natural non-stick properties of the ceramic-carbon matrix, coffee oils and micro-grounds cannot adhere to the basket walls. A simple rinse or a wipe with a microfiber cloth leaves it pristine. No stubborn residue, no lingering stale coffee odors—just pure, unadulterated flavor profile from shot to shot.Tips:To accommodate different brew styles and portafilters, the IKAPE Black Variable Diameter Basket sits perfectly flush with the bottom of your portafilter (no awkward protruding tips), making it 100% compatible with standard tamping stations.54mm to 32mm (Height: 33mm): Tailored for 54mm portafilters (e.g., Breville users). Ideal for 16g - 18g doses.58mm to 32mm (Height: 33mm): Sits perfectly flush in standard 58mm portafilters. Ideal for 16g - 18g doses.58mm to 32mm (Height: 38mm): Deep profile for higher-volume extractions. Ideal for 18g - 22g doses. (Note: Recommended if you prefer using a puck screen).NoteCoarsen Your Grind: This basket inherently increases backpressure. You MUST grind coarser than you would with a conventional flat basket. If your shot chokes, coarsen the grind further.Roast Adjustments:Light Roasts: Coarsen slightly less for an intensive extraction that tames sharp acidity.Medium-Dark Roasts: Go coarser to unlock rich, velvety, chocolate-like notes with a massive aroma.Puck Screen Note: If using a puck screen with an 18g dose, we highly recommend selecting the 38mm height variant to ensure ample headroom.
