Fellow Stagg [ X ] Pourover Coffee Filters went through a lot of R&D to land on the magic number of twenty flutes per filter. It was by no accident that twenty folds, not nineteen or twenty-one, provided the exact structure and rigidity needed to prevent the dreaded coffee filter collapse. These flat-bottomed coffee filters will help you brew a better cup without a papery aftertaste.
The paper filters were specially designed for coffee brewers with steeper slopes and utilize the “fill-up” brewing method.
