{"product_id":"rattleware-stainless-flat-bottom-espresso-tamper","title":"Rattleware Stainless Steel Flat-Bottom Espresso Tamper","description":"\u003cp class=\"product-lead\"\u003eThe Rattleware Stainless Steel Flat-Bottom Espresso Tamper is a round, flat-base tamper built for home baristas and working professionals who want consistent, repeatable puck compression. Constructed entirely from stainless steel with a compact ergonomic handle, it is available in five diameters (53 mm, 55 mm, 57 mm, 58 mm, and 58.3 mm) and two handle heights (3 inch and 3.5 inch) to match a wide range of portafilter baskets.\u003c\/p\u003e\n\n\u003ch2\u003eEven Compression, Every Pull\u003c\/h2\u003e\n\u003cp\u003eThe flat-bottom base of the Rattleware tamper distributes pressure uniformly across the entire coffee bed. An uneven or domed tamp leaves thin spots in the puck where water channels through faster, producing sour, uneven shots. A flat base eliminates that variable, so the grind distribution and dose become the factors you are actually dialing in rather than the tamp itself. For baristas working through high-volume service or home users building a repeatable routine, that consistency compounds across every shot.\u003c\/p\u003e\n\n\u003ch2\u003eStainless Steel Built for Daily Use\u003c\/h2\u003e\n\u003cp\u003eThe Rattleware tamper is machined from stainless steel throughout, including the handle. Stainless resists the moisture and coffee-oil exposure that a tamper sees every day at an espresso station, and it cleans quickly with a wipe or a rinse. The material also gives the tamper enough mass to seat the puck firmly without requiring excessive downward force, which reduces wrist fatigue during extended service.\u003c\/p\u003e\n\n\u003ch2\u003eHandle Fit Matters as Much as Base Diameter\u003c\/h2\u003e\n\u003cp\u003eThe compact ergonomic handle is sized to sit naturally in the palm without requiring a wide grip, which keeps the wrist in a neutral position during the tamp stroke. The two available heights, 3 inch and 3.5 inch, let you match the tamper to your hand size and to the clearance above your portafilter on your specific machine. Choosing the right height is as practical as choosing the right diameter: a handle that is too short forces the wrist into extension; one that fits lets you apply even pressure straight down.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlat-bottom base:\u003c\/strong\u003e Produces uniform puck compression across the full basket diameter.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStainless steel construction:\u003c\/strong\u003e Resists rust and coffee-oil buildup; wipes clean easily.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompact ergonomic handle:\u003c\/strong\u003e Supports a neutral wrist position during tamping.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFive diameter options:\u003c\/strong\u003e 53 mm, 55 mm, 57 mm, 58 mm, and 58.3 mm to fit common portafilter baskets.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwo handle heights:\u003c\/strong\u003e 3 inch and 3.5 inch available across most diameter options.\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\u003eDiameter\u003c\/th\u003e\n      \u003cth\u003eHandle Height\u003c\/th\u003e\n      \u003cth\u003eBase Style\u003c\/th\u003e\n      \u003cth\u003eMaterial\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e53 mm\u003c\/td\u003e\n      \u003ctd\u003e3 inch\u003c\/td\u003e\n      \u003ctd\u003eFlat\u003c\/td\u003e\n      \u003ctd\u003eStainless Steel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e53 mm\u003c\/td\u003e\n      \u003ctd\u003e3.5 inch\u003c\/td\u003e\n      \u003ctd\u003eFlat\u003c\/td\u003e\n      \u003ctd\u003eStainless Steel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e55 mm\u003c\/td\u003e\n      \u003ctd\u003e3 inch\u003c\/td\u003e\n      \u003ctd\u003eFlat\u003c\/td\u003e\n      \u003ctd\u003eStainless Steel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e57 mm\u003c\/td\u003e\n      \u003ctd\u003e3 inch\u003c\/td\u003e\n      \u003ctd\u003eFlat\u003c\/td\u003e\n      \u003ctd\u003eStainless Steel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e57 mm\u003c\/td\u003e\n      \u003ctd\u003e3.5 inch\u003c\/td\u003e\n      \u003ctd\u003eFlat\u003c\/td\u003e\n      \u003ctd\u003eStainless Steel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e58 mm\u003c\/td\u003e\n      \u003ctd\u003e3 inch\u003c\/td\u003e\n      \u003ctd\u003eFlat\u003c\/td\u003e\n      \u003ctd\u003eStainless Steel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e58 mm\u003c\/td\u003e\n      \u003ctd\u003e3.5 inch\u003c\/td\u003e\n      \u003ctd\u003eFlat\u003c\/td\u003e\n      \u003ctd\u003eStainless Steel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e58.3 mm\u003c\/td\u003e\n      \u003ctd\u003e3 inch\u003c\/td\u003e\n      \u003ctd\u003eFlat\u003c\/td\u003e\n      \u003ctd\u003eStainless Steel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003e58.3 mm\u003c\/td\u003e\n      \u003ctd\u003e3.5 inch\u003c\/td\u003e\n      \u003ctd\u003eFlat\u003c\/td\u003e\n      \u003ctd\u003eStainless Steel\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 Rattleware Flat-Bottom Espresso Tamper suits home espresso users and professional baristas who want a straightforward, durable stainless tamper in a diameter that matches their portafilter basket. The five diameter options and two handle heights make it practical for a wide range of machines and hand sizes.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis tamper does not include a calibrated or spring-loaded pressure mechanism, so it is not suited to buyers who specifically need a calibrated tamper that stops at a set pressure. It is also not a bottomless or convex-base tamper; buyers whose workflow requires a curved base should select accordingly.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eHow do I know which diameter to choose?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe correct tamper diameter matches the inner diameter of your portafilter basket. The most common size for home and commercial single-boiler machines is 58 mm, but 53 mm is standard on many entry-level and pod-compatible machines. Check your basket's stated size or measure the inner rim before selecting; a tamper that is too small will leave an untamped ring around the edge of the puck.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the difference between the 3 inch and 3.5 inch handle heights?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Rattleware Flat-Bottom Tamper is available in two handle heights, 3 inch and 3.5 inch, to accommodate different hand sizes and portafilter clearances. A taller handle suits larger hands or setups where the portafilter sits lower, allowing a more upright wrist during the tamp stroke. The shorter handle works well in tighter spaces or for smaller hands. Both heights share the same flat-bottom base and stainless steel construction.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eIs the tamper compatible with pressurized portafilter baskets?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Rattleware Stainless Steel Flat-Bottom Tamper can be used with pressurized baskets, but the flat base is most beneficial with standard (non-pressurized) baskets where even puck density directly affects extraction. With pressurized baskets, tamp pressure has less influence on shot quality because the basket's internal valve controls flow. The tamper's value is most apparent when paired with a standard basket and a consistent grind.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes the tamper include a tamping mat or stand?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Rattleware Flat-Bottom Espresso Tamper is sold as a standalone tamper only. No tamping mat, corner stand, or additional accessories are included. Rattleware does offer tamping mats and related barista tools separately in the CoffeeRoast Co. catalog.\u003c\/p\u003e","brand":"Rattleware","offers":[{"title":"53mm \/ 3\"","offer_id":68203093459165,"sku":"RW-5001620","price":41.99,"currency_code":"USD","in_stock":true},{"title":"53mm \/ 3.5\"","offer_id":68203093491933,"sku":"RW-5001616","price":41.99,"currency_code":"USD","in_stock":true},{"title":"55mm \/ 3\"","offer_id":68203093524701,"sku":"RW-5001621","price":41.99,"currency_code":"USD","in_stock":true},{"title":"57mm \/ 3\"","offer_id":68203093557469,"sku":"RW-5001622","price":41.99,"currency_code":"USD","in_stock":true},{"title":"57mm \/ 3.5\"","offer_id":68203093590237,"sku":"RW-5001618","price":41.99,"currency_code":"USD","in_stock":true},{"title":"58mm \/ 3\"","offer_id":68203093623005,"sku":"RW-5001623","price":41.99,"currency_code":"USD","in_stock":true},{"title":"58mm \/ 3.5\"","offer_id":68203093655773,"sku":"RW-5001619","price":41.99,"currency_code":"USD","in_stock":true},{"title":"58.3mm \/ 3\"","offer_id":68203093688541,"sku":"RW-5001623.3","price":41.99,"currency_code":"USD","in_stock":true},{"title":"58.3mm \/ 3.5\"","offer_id":68203093721309,"sku":"RW-5001619.3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0614\/3315\/1709\/files\/roundtamper-1.jpg?v=1792110377","url":"https:\/\/coffeeroastco.com\/zh-hant\/products\/rattleware-stainless-flat-bottom-espresso-tamper","provider":"CoffeeRoast Co.","version":"1.0","type":"link"}
