Its angle was adjust to fit the internal conical walls of the graycano dripper, which has a different angle as other conical drippers (for instance the V60).\nWith just a slight angle difference of -2,75o on the filter shape (once folded), the new filter fits perfectly over the graycano Lava Ribs. This prevents unwanted and random filter positioning, like tilted sitting or uneven contact with conical walls.The most common causes of uneven brewing are uneven extractions and inconsistent consistency. This adjustment brings the filter to a perfect fit for high consistency in extraction and flowrate.\n\nEach time when the paper filter sits differently inside the graycano dripper, it disrupts these circulations by either detaining or enhancing air and water flow. Even if no factor was changed intentionally, an extraction recipe can have different results. \nUsing the special edition filter inside the graycano dripper ensures consistency in coffee extraction. In this way, air and water circulation between the filter and dripper are greatly improved.\n\nThis graycano Special Edition filter extracte","images":["https://cdn.shopify.com/s/files/1/0275/3567/1361/files/graycano_filter_1.jpg?v=1762443713","https://cdn.shopify.com/s/files/1/0275/3567/1361/files/Sibarist_Fast_cone_Graycano.jpg?v=1722026441","https://cdn.shopify.com/s/files/1/0275/3567/1361/files/Graycano-07_db534548-d0a2-476b-b471-530b28367364.jpg?v=1722026425","https://cdn.shopify.com/s/files/1/0275/3567/1361/files/Graycano-24_9f2dd0e4-088e-46ad-985a-4fc3e68027ee.jpg?v=1712453177","https://cdn.shopify.com/s/files/1/0275/3567/1361/files/graycano-2.jpg?v=1687092080"],"price":27.75,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:25.762Z"},"share_url":"https://firestarter.network/l/lst_kmJqVkWO","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
