Sibarist FLAT Filters – High-Performance Flat-Bottom

The Sibarist FLAT Filters bring out unparalleled sweetness, complexity, and consistency in every cup. Available with FAST and B3 paper technologies, these filters allow brewers to push the boundaries of flavor while maintaining precise control. FAST technology ensures high-flow extractions with clean, vibrant flavor, while B3 offers added rigidity, improved sweetness, and minimal contact with the dripper for uniform saturation.

Unlike traditional fluted filters, the Sibarist FLAT Filters feature a smooth, non-fluted design registered by Sibarist to eliminate bypass and provide even water flow across the coffee bed. This unique geometry maximizes extraction surface and encourages full flavor development, giving home brewers, competitors, and professionals a cup free from papery residue and uneven extraction.

Crafted from 100% organic materials in Barcelona, Spain, the Sibarist FLAT Filters are sealed for freshness and packaged in FSC-certified sustainable paper. They are available in multiple sizes: FLAT S fits small brewers like Kalita 155, and FLAT M accommodates medium brewers such as Kalita 185. Whether you are dialing in recipes, testing flow rates, or chasing ultimate clarity, the Sibarist FLAT Filters deliver precise control, exceptional consistency, and pure coffee flavor in every brew.
