{"product_id":"hario-prism-ceramic-burr-hand-coffee-grinder","title":"Hario Prism Ceramic Burr Hand Coffee Grinder","description":"\u003cp class=\"product-lead\"\u003eThe Hario Prism is a manual, conical ceramic burr coffee grinder with an 800 mL capacity, built around a compact metal body designed for home use and travel. The grinder is available in Black and Silver; both share the same dimensions and capacity.\u003c\/p\u003e\n\n\u003ch2\u003eGrind With Less Heat, More Consistency\u003c\/h2\u003e\n\u003cp\u003eThe Prism uses conical ceramic burrs, which shave coffee beans rather than cracking them the way blade grinders do. Ceramic burrs transfer less heat than metal during grinding, producing a more uniform particle distribution that is easier to dial in and repeat across brews.\u003c\/p\u003e\n\n\u003ch2\u003eA Grind Setting You Can Return To\u003c\/h2\u003e\n\u003cp\u003eThe Prism's grind adjustment knob and nut are designed to be set and held, so once you find the right setting for your brew method you can return to it without re-calibrating each time. That repeatability matters whether you are dialing in a pour-over at home or packing the grinder for a trip and wanting consistent results on arrival.\u003c\/p\u003e\n\n\u003ch2\u003eCompact Build, Stable Footprint\u003c\/h2\u003e\n\u003cp\u003eThe outer body is aluminum alloy, keeping the grinder light while giving it the rigidity of a metal tool rather than a plastic one. A silicone rubber non-slip base holds the mill steady on a countertop while you crank, reducing the effort needed to keep it in place. At 280 mm wide by 136 mm deep by 170 mm tall, the Prism fits in a bag without taking up significant space.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConical ceramic burrs:\u003c\/strong\u003e shave rather than crack beans, reducing heat transfer during grinding\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable grind setting:\u003c\/strong\u003e knob-and-nut system holds its position for repeatable results\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAluminum alloy outer body:\u003c\/strong\u003e metal construction in a compact, travel-friendly footprint\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSilicone non-slip base:\u003c\/strong\u003e stabilizes the mill on a countertop while grinding\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e800 mL capacity:\u003c\/strong\u003e accommodates enough beans for multiple cups per grind session\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCapacity\u003c\/td\u003e\n      \u003ctd\u003e800 mL\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDimensions\u003c\/td\u003e\n      \u003ctd\u003eW 280 x D 136 x H 170 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight\u003c\/td\u003e\n      \u003ctd\u003e1.2 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBurr type\u003c\/td\u003e\n      \u003ctd\u003eConical ceramic\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eHandle material\u003c\/td\u003e\n      \u003ctd\u003eAluminium diecast, polypropylene\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOuter hopper \/ bottle\u003c\/td\u003e\n      \u003ctd\u003eAluminum alloy\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInner hopper \/ bottle\u003c\/td\u003e\n      \u003ctd\u003eABS resin\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLid\u003c\/td\u003e\n      \u003ctd\u003eMethacrylate resin\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShaft, spring, adjustment nut\u003c\/td\u003e\n      \u003ctd\u003eStainless steel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWasher, shaft cover, burr holder, adjustment knob\u003c\/td\u003e\n      \u003ctd\u003eNylon\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNon-slip base\u003c\/td\u003e\n      \u003ctd\u003eSilicone rubber\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eAvailable colors\u003c\/td\u003e\n      \u003ctd\u003eBlack, Silver\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCountry of manufacture\u003c\/td\u003e\n      \u003ctd\u003eChina\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThe Hario Prism suits home brewers and travelers who want a manual grinder with repeatable grind settings and a durable metal body.
