Futsushu
Saké that has less than 30% of the unwanted elements milled away is called Futsu-shu and is politely referred to as “bulk saké”. Futsu-shu is not a regulated beverage by the Japanese government and may have a variety of additives including sweeteners, colorings and bulk alcohol.
These are not considered as refined or as flavorful as the finest sakes, so keep that in mind when selecting sake for exotic cuisine. These are the sakes that should be served warm.
Futsushu
Futsushu is "everyday" or "value" sake. It has no rice polishing requirement.
