The convex bottom is milled from solid material – that's what \"billet\" means: manufactured from a solid block instead of pressed. The fine holes deliberately slow down the flow and give you a slow, quiet extraction. This is our observation, one of many.\u003c\/p\u003e\n\u003cp\u003eThe choice of sieve fundamentally changes the aroma profile – often more than many expect. Particle size and uniformity determine how cleanly extraction occurs, and pressure opens a time window in which the various aromatic compounds dissolve one after another. We always consider extraction in terms of weight ratio, 1:2 as a starting point, never by time alone. No right, no wrong – ultimately, what matters is that you enjoy the coffee.\u003c\/p\u003e\n\u003cp\u003eNobody needs a different sieve to make good espresso. But those who want to shape their extraction more consciously and explore a particularly calm, slow cup will find a tool here that is built precisely for that. You want it – or not, no must.\u003c\/p\u003e\n\u003ch3\u003eAt a Glance\u003c\/h3\u003e\n\u003ctable class=\"ccc-compare-table\"\u003e\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, milled from solid (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\u003c\/table\u003e\n\u003cp\u003eThe 54 mm sieve fits into standard 54 mm portafilters, and the 58 mm sieve into standard 58 mm portafilters.
