It adds a layer of mesh to help spread incoming water across the puck. A simple addition to your espresso routine, not a shortcut around dialing in your coffee.\u003c\/p\u003e\u003cp\u003eChoose a 51mm or 58mm screen to suit your basket. Both sizes are listed at 1.7mm thick, so check the space above your coffee before adding one to your setup.\u003c\/p\u003e\u003ch2\u003eThe details\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless steel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter options:\u003c\/strong\u003e 51mm or 58mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e 1.7mm for either size.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e One puck screen in your selected size.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow do you use a puck screen?\u003c\/h2\u003e\u003cp\u003eDose, distribute, and tamp your coffee as usual, then place the screen flat on top of the puck before locking in the portafilter. Make sure there’s enough headspace so the screen doesn’t press against the machine’s shower screen. After brewing, let it cool before removing it, rinse away the grounds, and keep the mesh clean between uses.\u003c\/p\u003e\u003ch2\u003eWhich size should you choose?\u003c\/h2\u003e\u003cp\u003eCheck your basket’s internal diameter and the recommended puck screen size for your setup. Pick 51mm or 58mm based on basket fit, not machine brand alone. The screen should sit flat without binding against the basket walls.\u003c\/p\u003e\u003ch2\u003eDoes it replace your machine’s shower screen?\u003c\/h2\u003e\u003cp\u003eNo. This is a removable screen that goes inside the portafilter, on top of the coffee. It is not a replacement part for the shower screen attached to your machine.\u003c\/p\u003e\u003ch2\u003eWill it fix channeling?\u003c\/h2\u003e\u003cp\u003eNot on its own. Channeling happens when water finds easier paths through the coffee. A puck screen can help spread incoming water, but grind size, dose, distribution, and tamping still matter.\u003c\/p\u003e\u003cp\u003eIf you want to try a puck screen, start with fit and headspace. Keep the rest of your routine consistent so you can judge what changes in your cup.\u003c\/p\u003e","brand":"Alchemy Harvest Coffee","offers":[{"title":"51mm","offer_id":53669860966689,"sku":"CJJT173515801AZ","price":13.99,"currency_code":"USD","in_stock":true},{"title":"58mm","offer_id":53669860999457,"sku":"CJJT173515802BY","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0990\/6651\/1649\/files\/116579d0-f912-47b4-a124-ef5467ec1ca8.jpg?v=1791055614","url":"https:\/\/shopcoffeehobby.com\/products\/coffee-machine-secondary-water-distribution-network","provider":"Shop Coffee Hobby","version":"1.0","type":"link"}
