{"product_id":"hario-polaris-coffee-scale-white","title":"Hario POLARIS Coffee Scale, White","description":"\u003cp class=\"product-lead\"\u003eThe Hario POLARIS Coffee Scale is a smart brewing scale designed for pour-over and drip coffee, combining real-time weight measurement with built-in extraction ratio calculation and a brewing percentage display. The POLARIS Scale has a capacity of 2,000 g and a minimum measurement of 0.1 g, and is available in White.\u003c\/p\u003e\n\n\u003ch2\u003eDial In Your Recipe Before You Pour\u003c\/h2\u003e\n\u003cp\u003eThe POLARIS Scale's extraction ratio function takes the guesswork out of recipe building. Enter the weight of your ground coffee and select a ratio (tighter ratios from 1:1 to 1:14 for a stronger, more concentrated cup; wider ratios from 1:15 to 1:30 for a lighter, more delicate brew), and the scale calculates the total water target automatically. For a brewer working through a new coffee or dialing in an unfamiliar grind, this means fewer wasted grams and faster iteration toward a repeatable result.\u003c\/p\u003e\n\n\u003ch2\u003eFollow Every Pour in Real Time\u003c\/h2\u003e\n\u003cp\u003eDuring the brew, the POLARIS Scale tracks how much water has been added and displays the brewing percentage on screen, showing exactly where you are relative to the total pour target at any moment. This live feedback is especially useful for multi-stage pours such as bloom-and-pulse techniques, where hitting each interval accurately shapes extraction. A dedicated Time Mode with a standby indicator adds a built-in timer so weight and time can be tracked together without a separate device.\u003c\/p\u003e\n\n\u003ch2\u003eA Compact Platform Built for the Brew Bar\u003c\/h2\u003e\n\u003cp\u003eThe POLARIS Scale measures 127 mm wide by 165 mm deep by 27 mm tall, a footprint sized to sit under a V60 or similar dripper without crowding the counter. The body is ABS and acrylic resin, and silicone rubber feet keep it from shifting during pouring. At approximately 437 g including its individual box, the scale is light enough to pack for travel or move between brew stations.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtraction ratio calculator:\u003c\/strong\u003e set a ratio from 1:1 to 1:30; total water target is calculated automatically from coffee weight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrewing percentage display:\u003c\/strong\u003e shows real-time progress as a percentage of total water poured\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTime Mode with standby indicator:\u003c\/strong\u003e built-in timer activates on demand alongside weight tracking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2,000 g capacity, 0.1 g minimum:\u003c\/strong\u003e covers single-cup through large-batch pour-over brewing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSilicone rubber non-slip feet:\u003c\/strong\u003e keeps the platform stable on wet or smooth surfaces\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\u003e2,000 g\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMinimum weight\u003c\/td\u003e\n      \u003ctd\u003e0.1 g\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDimensions (W x D x H)\u003c\/td\u003e\n      \u003ctd\u003e127 mm x 165 mm x 27 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight (with individual box)\u003c\/td\u003e\n      \u003ctd\u003eApprox. 437 g\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBody material\u003c\/td\u003e\n      \u003ctd\u003eABS resin, Acrylic resin\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNon-slip parts\u003c\/td\u003e\n      \u003ctd\u003eSilicone rubber feet\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eColour\u003c\/td\u003e\n      \u003ctd\u003eWhite\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 POLARIS Scale suits home brewers and coffee enthusiasts who brew by weight and want ratio guidance and real-time pour feedback built into the scale itself, without relying on a separate app or manual calculation. Its 2,000 g capacity covers single-cup through multi-cup pour-over sessions.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThe POLARIS Scale is not suited to espresso brewing, where sub-0.1 g resolution and a low-profile form factor are typically required. It is also not a kitchen or food scale for general-purpose weighing beyond coffee preparation.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eHow does the extraction ratio function work?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eOn the Hario POLARIS Scale, you place your ground coffee on the platform and use the plus and minus buttons to select an extraction ratio. The scale multiplies the coffee weight by that ratio and displays the resulting water target in grams. During the pour, the screen shows the current water added divided by the total target, expressed as a percentage, so you can track progress without doing any arithmetic.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat ratio range does the POLARIS Scale support?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Hario POLARIS Scale supports extraction ratios from 1:1 through 1:30. Ratios in the 1:1 to 1:14 range produce a stronger, more concentrated brew; ratios from 1:15 to 1:30 produce a lighter brew that highlights clarity and delicate flavors. The ratio is set manually using the plus and minus buttons before or during brewing.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes the POLARIS Scale have a built-in timer?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. The Hario POLARIS Scale includes a Time Mode that can be activated by pressing the Time Mode button; the button lights up when the timer is on standby. This allows brewers to track both weight and elapsed time on the same device during a pour.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the maximum weight the POLARIS Scale can measure?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Hario POLARIS Scale has a maximum capacity of 2,000 g and measures from a minimum of 0.1 g. This range covers most pour-over and drip brewing scenarios, from a single small cup through a full carafe.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat materials is the POLARIS Scale made from?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe body of the Hario POLARIS Scale is constructed from ABS resin and acrylic resin. The base includes silicone rubber feet to prevent the scale from sliding on smooth or wet surfaces during pouring.\u003c\/p\u003e","brand":"Hario","offers":[{"title":"Default Title","offer_id":68253816422621,"sku":"HR-CST-2000-W","price":85.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0614\/3315\/1709\/files\/HR-CST-200-W.jpg?v=1792635443","url":"https:\/\/coffeeroastco.com\/products\/hario-polaris-coffee-scale-white","provider":"CoffeeRoast Co.","version":"1.0","type":"link"}
