Gekkeikan Nigori is a rough-filtered Junmai-shu. By definition Nigori means ‘cloudy’ and this style of sake is thicker and creamier in texture, with a milk-like appearance. The ‘cloudiness’ comes from the rice sediment which remains in the sake after it has been passed through a special coarse-mesh filter. The tradition of rough-filtering sakes has been used in Japan for many centuries.
