Even with a lean 14–16g dose, you'll taste what it's all about: sweetness that comes to the forefront.\u003c\/p\u003e\n\n\n\u003cp\u003eNo one needs a special basket for good espresso – the original basket does its job. You want it because the cup becomes sweeter, rounder, and more uniform. 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 Big Bang is IMS's latest idea: 585 holes concentrated towards the center of the basket – the distance between the holes increases towards the rim. This specifically directs the flow centrally and ensures exceptionally even flow through the entire puck, preventing channeling. You'll taste the result as significantly more sweetness, while acidity recedes – caramel, chocolate, and nuts come to the forefront. The holes are Ø 0.30 mm with a conical cross-section; the basket is ridgeless, has a flat bottom, and an electropolished, easy-to-clean surface. Espresso is extraction via a weight ratio, usually 1:2; taste and smell are inseparable, a large part arises 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 Big Bang (B702TFH21.5BB), 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, electropolished\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\u003e585 holes (Big Bang pattern), Ø 0.30 mm, conical · perforated Ø 49 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eBottom \/ Design\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003eflat · 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\u003e14–16 g\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\u003e21.5 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eFit\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003e58 mm portafilters, E61 · Tamper Ø 58–58.4 mm · Rim-Ø 70 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 a sweet, round espresso – especially good with medium to darker roasts.
