Sibarist Cone 28-30 FAST Specialty Coffee Filter

The Sibarist Cone 28-30 FAST is a high-performance coffee filter engineered specifically for narrow-angle brewers, such as the Cafec Deep 27. Designed for professional baristas and home enthusiasts, this filter utilizes Sibarist’s proprietary FAST technology to provide unparalleled flow rate control and cup clarity.

Unlike traditional wood-pulp filters, the FAST range is constructed from a unique blend of abaca fibers, cellulose, and plant-based fibers. This composition allows for a significantly higher permeability, reducing the “contact time” between water and coffee. This allows the brewer to grind much finer than usual, increasing extraction without the risk of bitterness or “stalling.”

Key Features & Benefits

• 28-30° Geometry: Specifically tailored for narrow-angle conical drippers, ensuring a perfect fit with zero paper bunching or air gaps.
• Unmatched Flow Rate: Reduces draw-down time by up to 40% compared to standard paper filters, preserving delicate aromatics and bright acidity.
• Clean Cup Profile: Minimal paper taste interference, ensuring that the true terroir of specialty coffee is the primary focus of the brew.
• Sustainable Sourcing: 100% organic and compostable, manufactured in Barcelona with a focus on environmental responsibility.

Technical Specifications

This filter is the solution for brewers seeking maximum clarity and speed. By utilizing a narrower geometry, the coffee bed is deeper, which typically slows down extraction. The FAST material counteracts this, allowing for a deep-bed extraction with the velocity of a flat-bottom brewer. It is the ideal choice for light-roast specialty coffees where acidity and floral complexity are paramount.
