{"product_id":"hario-walnut-series-ceramic-coffee-mill","title":"Hario Walnut Series Ceramic Coffee Mill","description":"\u003cp class=\"product-lead\"\u003eThe Hario Walnut Series Ceramic Coffee Mill is a hand-crank manual grinder built for home brewers who want consistent, adjustable grinding in a grinder made from walnut wood, ceramic, and stainless steel. The tall-profile body pairs a matching dark walnut hopper and canister with a cast aluminum alloy handle, and the grinder is made in Japan. The hopper holds approximately 30 g of coffee beans per session.\u003c\/p\u003e\n\n\u003ch2\u003eConical Ceramic Burrs for a Consistent Grind\u003c\/h2\u003e\n\u003cp\u003eThe Walnut Series mill uses conical ceramic burrs, which shave coffee beans rather than cracking or smashing them the way blade grinders do. Because ceramic transfers less heat than steel during grinding, the beans reach the catch canister without the thermal stress that can dull volatile aromatics. The grind setting is adjustable and holds its position for repeat use, so a setting dialed in for a V60 or French press stays put between sessions without re-calibration.\u003c\/p\u003e\n\n\u003ch2\u003eMaterials Built for Daily Use\u003c\/h2\u003e\n\u003cp\u003eThe body and handle grip are walnut wood, giving the mill a solid feel and a warm look that holds up to daily handling. The shaft and spring are stainless steel for durability at the core of the mechanism, while the cast aluminum alloy handle provides more leverage and a cleaner profile than a plastic alternative. An anti-slip urethane sticker on the base keeps the canister stable on a countertop while grinding. The lid is methacrylate resin, and the lower O-ring is silicone rubber to keep grounds contained.\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, producing a consistent, adjustable grind\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWalnut wood body and handle grip:\u003c\/strong\u003e matching dark wood hopper, canister, and grip throughout\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCast aluminum alloy handle:\u003c\/strong\u003e stronger and slimmer than plastic handles\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStainless steel shaft and spring:\u003c\/strong\u003e durable core mechanism\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable grind setting:\u003c\/strong\u003e holds position for repeatable results across brew methods\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eMade in Japan\u003c\/strong\u003e\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\u003eDimensions\u003c\/td\u003e\n      \u003ctd\u003eW 164 x D 81 x H 215 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight\u003c\/td\u003e\n      \u003ctd\u003eApprox. 400 g\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eHopper capacity\u003c\/td\u003e\n      \u003ctd\u003eApprox. 30 g of coffee beans\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\u003eBody and handle grip\u003c\/td\u003e\n      \u003ctd\u003eWalnut wood\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eHandle\u003c\/td\u003e\n      \u003ctd\u003eAluminum alloy\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShaft and spring\u003c\/td\u003e\n      \u003ctd\u003eStainless steel\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\u003eInner hopper\u003c\/td\u003e\n      \u003ctd\u003ePolypropylene\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBurr holder, grind adjustment nut, washer\u003c\/td\u003e\n      \u003ctd\u003eNylon\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLower O-ring\u003c\/td\u003e\n      \u003ctd\u003eSilicone rubber\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eAnti-slip sticker\u003c\/td\u003e\n      \u003ctd\u003eUrethane resin\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOrigin\u003c\/td\u003e\n      \u003ctd\u003eMade in Japan\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 Walnut Series mill suits home brewers who grind one or two portions at a time and want a grinder that looks as considered as the rest of their brew setup. The approximately 30 g hopper capacity covers a standard single or double pour-over dose, and the adjustable ceramic burrs work across a range of brew methods from espresso-adjacent to coarse filter.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThe Walnut Series mill is not suited to grinding large batches in a single session; the roughly 30 g hopper capacity is a per-fill limit, not a daily-volume rating. This is a manual hand-crank grinder and does not have a motor or electric drive of any kind.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eHow much coffee can the Hario Walnut Series mill grind at once?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Hario Walnut Series Ceramic Coffee Mill has a hopper practical capacity of approximately 30 g of whole coffee beans per fill. That covers a typical single or double pour-over dose. For larger batches, the hopper would need to be refilled and ground in multiple passes.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat type of burrs does the Walnut Series mill use, and why does it matter?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Walnut Series mill uses conical ceramic burrs. Ceramic burrs transfer less heat during grinding than metal alternatives and shave beans rather than cracking them, which produces a more consistent particle distribution. The grind setting is adjustable and holds its position, making it repeatable across brew sessions.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eIs the Hario Walnut Series mill electric or manual?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Hario Walnut Series Ceramic Coffee Mill is a fully manual, hand-crank grinder. It has no motor or power source. Grinding is done by turning the cast aluminum alloy handle by hand, which makes it suitable for travel or use anywhere without access to an outlet.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat materials make up the Walnut Series mill?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Hario Walnut Series mill's body and handle grip are walnut wood; the burrs are ceramic; the shaft and spring are stainless steel; the handle is aluminum alloy; the lid is methacrylate resin; and the inner hopper is polypropylene. The lower O-ring is silicone rubber and the base carries a urethane resin anti-slip sticker. The grinder is made in Japan.\u003c\/p\u003e","brand":"Hario","offers":[{"title":"Default Title","offer_id":68253807771869,"sku":"HR-MCG-2-WN","price":85.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0614\/3315\/1709\/files\/IMG_4095_6897ca18-8bad-47d7-94da-946e58d1fc13.jpg?v=1792635402","url":"https:\/\/coffeeroastco.com\/zh-hant\/products\/hario-walnut-series-ceramic-coffee-mill","provider":"CoffeeRoast Co.","version":"1.0","type":"link"}
