I n fact, Ginjo-shu is unique in this respect. No other alcoholic beverage made from grain has such a natural fruity aroma. N o, definitely not. It's illegal to add any artificial preservatives to sake, although their use in wine is permitted in many countries. S ince sake is an extremely delicate alcoholic beverage that is especially sensitive to heat and light, it must be stored in a cool, dark place.
Refrigeration is recommended.
Exposing sake to sunlight can change its taste as well as its color. E xposure to air can reduce the quality of sake over time. This means that once you have opened a bottle, it's best to finish it fairly soon.
