The convex bottom is machined from solid stock – that's what «billet» means: made from a solid block instead of stamped. The fine holes deliberately slow the flow and give you a slow, calm extraction. That's our observation, one of many.\u003c\/p\u003e\n\u003cp\u003eBasket choice changes the aroma profile fundamentally – often more than most people expect. Particle size and consistency determine how cleanly the extraction runs, and pressure opens a time window in which the different aromatic compounds release one after another. We always think of extraction in terms of weight ratio, 1:2 as a starting point, never by time alone. No right, no wrong – in the end, what matters is that the coffee tastes good to you.\u003c\/p\u003e\n\u003cp\u003eNobody needs a different basket to make good espresso. But if you want to shape your extraction more deliberately and explore an especially calm, slow cup, here's a tool built exactly for that. Whether you want it is entirely your call – no obligation either way.\u003c\/p\u003e\n\u003ch3\u003eAt a glance\u003c\/h3\u003e\n\u003ctable class=\"ccc-compare-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eNormcore (direct import CCC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDesign\u003c\/td\u003e\n\u003ctd\u003eConvex, machined from solid stock (billet)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSizes\u003c\/td\u003e\n\u003ctd\u003e54 mm · 58 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDose\u003c\/td\u003e\n\u003ctd\u003e18 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlow\u003c\/td\u003e\n\u003ctd\u003e0.18 mm (low flow)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThe 54 mm basket fits standard 54 mm portafilters, the 58 mm basket fits standard 58 mm portafilters.
