{"product_id":"calibrated-espresso-tamper-walnut","title":"Calibrated Tamper, Walnut \u0026 Steel, 51\/53\/58mm","description":"\u003cp\u003eA calibrated tamper puts a spring in the collar between the handle and the base. Press down, and the spring gives at the same point each time, so the puck sees the same pressure on every shot. A numbered ring lets you set that pressure and repeat it shot to shot.\u003c\/p\u003e\n\u003cp\u003eThe handle is walnut. The base that meets the coffee is mirror-polished SUS304 stainless steel, with a matte aluminium body in between. The spring also self-levels, keeping the base flat as you press, which reduces the tilt that starts channelling at the edge of the puck.\u003c\/p\u003e\n\u003cp\u003ePick a flat base for a smooth face or a grooved base for a textured one. Both come in three basket diameters.\u003c\/p\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSizes\u003c\/td\u003e\n\u003ctd\u003e51mm, 53mm and 58mm basket diameters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFit\u003c\/td\u003e\n\u003ctd\u003e58mm is the standard commercial and E61 basket size; 51 and 53mm suit smaller home baskets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHandle\u003c\/td\u003e\n\u003ctd\u003eNatural walnut\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase\u003c\/td\u003e\n\u003ctd\u003eMirror-polished SUS304 stainless steel, matte aluminium body\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase face\u003c\/td\u003e\n\u003ctd\u003eFlat (smooth) or grooved (textured), by variant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure\u003c\/td\u003e\n\u003ctd\u003eSpring-loaded with a numbered self-leveling ring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Grao Brewing","offers":[{"title":"Flat bottom-53mm","offer_id":43729491984443,"sku":"14:200006152#Flat bottom-53mm","price":59.99,"currency_code":"AUD","in_stock":true},{"title":"Flat bottom-51mm","offer_id":43729492017211,"sku":"14:200006151#Flat bottom-51mm","price":59.99,"currency_code":"AUD","in_stock":true},{"title":"Thread bottom-51mm","offer_id":43729492049979,"sku":"14:200006154#Thread bottom-51mm","price":59.99,"currency_code":"AUD","in_stock":true},{"title":"Flat bottom-58mm","offer_id":43729492082747,"sku":"14:200006153#Flat bottom-58mm","price":59.99,"currency_code":"AUD","in_stock":true},{"title":"Thread bottom-58mm","offer_id":43729492115515,"sku":"14:200000195#Thread bottom-58mm","price":59.99,"currency_code":"AUD","in_stock":true},{"title":"Thread bottom-53mm","offer_id":43729492148283,"sku":"14:200004890#Thread bottom-53mm","price":59.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0683\/0109\/4971\/files\/hf_20260713_134549_5aa55a2e-48d3-40fe-972a-992bbcae5c7cLarge.jpg?v=1783958482","url":"https:\/\/graobrewing.com\/products\/calibrated-espresso-tamper-walnut","provider":"Grao Brewing","version":"1.0","type":"link"}
