Futsu (futsu-shu) is the most generic category of sake, accounting for around 75 percent of sake production. It requires none of the strict production criteria of the higher-quality classifications like junmai or honjozo, and is to Japan what blended Scotch is to Scotland, or what vin de table is to France.
Sake is made from rice that has been polished to expose its starch. Generally speaking, the more the rice is polished, the purer the sake, and many of the special-designation sakes have legally stipulated polishing requirements. There are no such regulations on the production of futsu sake, and unlike in the production of junmai sake, neutral alcohol may be added following fermentation. The lack of regulations is meant to increase production and lower the cost for consumers.
Futsu sake is often served warm to soften any rough flavors. James Bond famously enjoyed his sake "served at the correct temperature, 98.4 degrees Fahrenheit".
