FLAT

The FLAT is the unique and original non-fluted flat-bottomed filter for coffee drippers, designed and registered by SIBARIST. It offers a unique, smooth and unobstructed area that offers the perfect and even space for brewing with full access to the coffee bed. It eliminates the bypass effect and provides the most even extraction with the maximum coffee particle yield, preventing coffee particles from being trapped in fluted areas.

The FLAT uses the FAST Specialty Coffee Filter technology, its no-waves surface eliminates the bypass to provide a regular water contact to all coffee particles and continuous turbulence. Also have all the FAST Specialty Coffee Filter characteristics.

A COMPLETE FIT - ELIMINATING BYPASS

The air flow between the filter and the brewer is eliminated by the flat paper’s adhesion to the dripper walls when wet, thereby removing the “bypass” that can cause astringency in the cup.

The FLAT is very sensitive to dripper geometries and properties since once it is wet, the filter stitches to the dripper walls, eliminating the bypass effect and the air circulation through the filter. This makes it possible to obtain different flow rates depending on the dripper used, opening a new world of possibilities for the barista to experiment with and select the dripper depending on the target extraction time.

A CLEAN SILHOUETTE - NO WAVES

The filter CONE FAST eliminates the air gaps created between the waves of classic flat bed filter which ones produce the bypass effect, the FLAT FAST decreases any air circulation between the filter and the dripper. The FAST Specialty Coffee paper provide enough permeability to provide a fast and excellent flow rate without these extra air channels. In addition, provides a characteristically clean taste and silky mouthfeel that is free of paper flavor.

The free waves shapes do not allow to the coffee particles to be trapped on the waves, providing a more uniform and complete extraction, ensuring that all the coffee particles used on the brew will be in contact with the water in a more uniform and complete fashion providing a more even extraction. The smooth surface offers a better geometry to create a more uniform turbulence.

UNIFORMITY IN TURBULENCE

A smooth, obstacle-free infusion volume provides freedom, more even turbulence and uniform circulation of particles in the slurry when pouring, resulting in even extractions.

MORE CONTROL OVER EXTRACTION

The pouring speed and turbulence have a direct effect on the filter’s flow and drawdown: cause-effect, making it possible to lengthen or shorten the extraction with the pouring valence.

UTILIZATION OF THE FULL COFFEE BED

Because the filter adheres to the dripper walls, it provides 100% access and view of the coffee-bed area, gaining you more pouring surface and full access to the coffee slurry.

FLOW RATES

The FLAT is very sensitive to dripper geometries and properties, making it possible to obtain different flow rates depending on the dripper used, opening up a new world of possibilities for the barista to experiment with and select the dripper combo depending on the target extraction time. Pair with a flow-rate-compatable scale to explore a new world of possibilities!

CONSISTENCY AND REPEATABILITY

Created to offer the highes consistency and coffee particle extraction uniformity, the filter always provides the same geometry, with no coffee trapped or isolated in any fluted areas, providing continuous even agitation.

HIGHER EXTRACTION

The FAST Specialty Coffee Filter flow has the potential to yield higher extractions and performance values. It also has a lower LRR..

Moreover: No paper impact on flavor

It leaves no trace of flavor or aroma in the cup. The material uses thinner fibers and less substance.
