{"type":"firestarter.listing","listing":{"id":"lst_eekN2C_1","product_name":"SIBARIST FAST WAVE","category":"Paper Filter","description":"The Sibarist FAST 185-size filters are 2 -4 cup filters engineered for speed, clarity, and consistency, designed specifically for flat-bottom brewers such as the Kalita Wave 185, Orea, and April. Their advanced paper construction delivers a noticeably faster flow rate than standard 185 filters, enabling more flexible brew methods and quicker drawdowns.\nPerformanceThanks to their high-permeability structure, FAST filters allow finer grinds and more aggressive pouring without clogging. This efficiency enhances extraction control and shortens total brew time, making brewing more streamlined and predictable, even with challenging coffees.\nFlavor ProfileThe FAST paper minimizes oil and fines retention, resulting in a cup that is exceptionally clean and bright. Acidity, fruit tones, and delicate aromatics become more pronounced, making these filters especially well-suited to light and washed coffees where clarity is a priority.\nConstruction & MaterialsCrafted from high-quality, sustainably sourced fibers, the filters maintain strength, shape, and neutrality during brewing. They are designed to avoid imparting paper taste while maintaining structural integrity in flat-bottom drippers.\nFor home brewers and professionals seeking maximum precision, vibrant clarity, and consistent high performance, the Sibarist FAST 185 filters offer a specialized, high-control tool that enhances both workflow and cup quality.","images":["https://cdn.shopify.com/s/files/1/0275/3567/1361/files/Sibarist_Wave-1.jpg?v=1764887084","https://cdn.shopify.com/s/files/1/0275/3567/1361/files/Sibarist_Wave-2.jpg?v=1764887084","https://cdn.shopify.com/s/files/1/0275/3567/1361/files/Sibarist_Wave_-_2_332c922c-cbfe-46c3-8975-7502ca876970.jpg?v=1764886427","https://cdn.shopify.com/s/files/1/0275/3567/1361/files/Sibarist_Wave_-_box_468b3928-eb12-4342-823f-26fc31a39b27.jpg?v=1764886427"],"price":21,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:25.454Z"},"share_url":"https://firestarter.network/l/lst_eekN2C_1","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
