Nigori-zake, thick like milk
Sake, made from rice, comes in all grades and qualities, usually hanging around the 12% alcohol range. One type however, is a bit unique, and also has a higher alcohol content: Nigori-zake.
This is unfiltered sake. If you have ever washed white rice before cooking it, you have seen a thick almost milk-like runoff from the rice. With Nigori, this is all left in for the purpose of increased fermentation, and it's much more filling and bitter. It is best served hot or cold, but not too enjoyable at room temperature.
Ask for Nigori-zake at a liquor store, and try it for yourself!
