That means more coffee makes it into your cup, with less old coffee left behind to mix with your next dose.\u003c\/p\u003e\n\u003cp\u003eThe included adapter also replaces the Niche Zero's stock clear lid and keeps the lid interlock engaged. Instead of having to load your beans before starting the grinder, you can start the Niche first and add your beans while the burrs are already spinning. This makes hot-starting easy and also gives you the option to manually slow-feed beans for greater control over how they enter the burrs.\u003c\/p\u003e\n\u003cp\u003eFor everyday espresso, use the silicone bellows directly on the adapter for a compact setup with up to 30g of capacity. Need more room? Add the precision-machined aluminum hopper for up to 90g of total capacity, making it easy to grind large filter doses, a full pot of coffee, or multiple espresso doses without repeatedly reloading the grinder.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eThis listing is for the hopper system only.
