Be the first ones to get the B3 FLAT Specialty Coffee Filter!

The B3 FLAT Specialty Coffee Filter utilizes the B3 Specialty Coffee Filter paper technology, jointly developed by Sibarist and 2021 World Brewers Cup Champion Matt Winton. This FLAT filter is for flat bed drippers (Kalita 185 style).

The B3 FLAT filter shape provides a brewing bed that promotes even extraction of the coffee particles, high uniformity turbulence and full access to the coffee bed. The B3 rigidness produce a minimum contact surface with the dripper and provides a fast extraction, but its material thickness and low porosity provides sweeter and clean cups, lowering bypass during the brewing process.

Sibarist packaging are made using composable materials.

B3 Flat filters are packaged in a flat stack with pre-folded creases for users to fold.

FILTER PREPARATION

1. Fold the 4 edges of the filter, following the indentation marks on the paper.When folding, it is fine to go over the folds, with no need to avoid the center area of the filter.
   
2. Place the filter on top of the dripper and gently push the edges of the filter with both hands to fold inwards
   
3. Starting from the center, gently and slowly rinse the filter with hot water by moving towards the outer edge in circular motion, while making sure that the entire surface of the filter is stuck to the walls of the dripper, without leaving any air channels between the filter and the filter holder.
