This is precisely what the convex base of this basket is designed for: it precisely directs the coffee towards the center during extraction.\u003c\/p\u003e\n\n\n\u003cp\u003eNobody needs a competition basket to pull good espresso – the original basket does its job. You want it because the extraction becomes clearer, rounder, and more beautiful in a bottomless portafilter. This is one of many possible decisions, and we respect both directions.\u003c\/p\u003e\n\n\n\u003ch3\u003eWhat makes this basket special\u003c\/h3\u003e\n\n\u003cp\u003eThe \"C\" in the name stands for Convex: the convex base directs the flow to the center and creates a focused central stream in the bottomless portafilter. The 715 round holes with a conical cross-section in a hexagonal pattern are a patented IMS innovation – for a dense crema and even flow to the rim. Ridgeless and made of highly polished AISI 304 stainless steel: less coffee residue, easier knocking out, long lifespan. Espresso is extraction based on a weight ratio, usually 1:2; what you taste is density, sweetness, and a long finish. It is our observation that the choice of basket fundamentally changes the aroma profile.\u003c\/p\u003e\n\n\n\u003ch3\u003eAt a glance\u003c\/h3\u003e\n\n\u003ctable class=\"ccc-compare-table\"\u003e\n\n\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003eIMS Competition (B702TCH28.5E), Italy\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003eStainless steel AISI 304, highly polished\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003ePerforation\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003e715 conical holes, Ø 0.30 mm, hexagonal (E) · perforated Ø 49 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eBase \/ Design\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003eConvex (C) · cylindrical, ridgeless\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eDose\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003e18–22 g (2–3 cups)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eHeight\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003e28.5 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003eBottomless 58 mm portafilters only · Tamper Ø 58–58.4 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\n\n\n\u003c\/table\u003e\n\n\n\u003ch3\u003eWho it's for\u003c\/h3\u003e\n\n\u003cp\u003eFor anyone who loves the focused central stream in a bottomless portafilter and doses high (18–22 g) – any budget is welcome.
