Sibarist filters are designed to let the flavor of your coffee stand alone with no paper flavor and as little impact on the coffee's flavors as possible. Sibarist uses an incredible paper made 100% organic, and each paper consists of Abaca fiber, European Pine cellulose, and vegetable-derived PLA (polylactic acid). You can brew faster at a finer grind, getting a higher extraction without worrying about choking your brew.
