You want it because the cup becomes clearer and rounder. 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\u003eIMS's exclusive competition perforation is patented: 715 holes with a conical cross-section, Ø 0.30 mm, at micro-spacing, on a perforated surface of Ø 49 mm – calibrated for uniform flow. The cylindrical shape with a slightly convex bottom and rounded edges ensures that the entire puck is utilized, and facilitates drying and knocking out. Espresso is extraction by weight ratio, usually 1:2; what you taste is density, sweetness, a clear crema, and a rounded finish. Taste and smell are inseparable, a large part of which occurs retronasally. 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 (B682T), 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\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 · perforated Ø 49 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eDesign\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003ecylindrical, ridgeless, convex bottom\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\u003e12–18 g (up to 20 g possible)\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\u003e24.5 mm (H24.5)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003eRim-Ø 70 mm · inner Ø 60 mm · Tamper Ø 58–58.5 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 looking for a ridgeless basket with competition perforation in the classic double shot range – any budget is welcome.
