Nigori or nigorizake (濁り酒; にごり酒) is a variety of sake, an alcoholic beverage produced from rice.

Nigori sake is filtered using a broader mesh, resulting in the permeating of fine rice particles and a far cloudier drink.

[2][3] Unfiltered sake is known as doburoku (どぶろく, but also 濁酒)[2][3] and was originally brewed across Japan by farming families.

The government determined that as long as the holes in the mesh were no larger than 2 millimeters in diameter, the result of filtration using the cage could legally be considered sake.

[5] In 2010, a brewer from Akita Prefecture came up with a dark version of nigori sake, the color of which is due to the addition of edible finely powdered charcoal.
