Frequently Asked Questions

Sake does not have a strict expiration date, but for the best flavor, we recommend enjoying it within about one year from the production date, or within about six months for unpasteurized nama sake. After opening, keep the bottle upright in a refrigerator or another cool, dark place and enjoy it within one to two weeks.

For those trying sake for the first time, we recommend fruity and easy-to-drink styles such as junmai daiginjo or sparkling sake. For everyday meals, we recommend dry sake such as tokubetsu junmai, which has a crisp finish and pairs well with food.

Sake categories are mainly determined by ingredients and rice polishing ratio. Junmai sake is made only with rice, rice koji, and water, without added brewing alcohol. Daiginjo sake is made with rice polished to 50% or less and fermented slowly at low temperatures, giving it a refined and aromatic character. At Naniwa Shuzo, we handcraft each sake to bring out its own character.

Nama sake is sake shipped without the usual pasteurization process, giving it a fresh and fruity flavor. It must be refrigerated. Genshu is sake that has not been diluted with water after pressing, allowing you to enjoy a richer and more powerful taste from the rice.

Both are cloudy styles of sake, but they are classified differently under Japanese liquor regulations. Nigori sake is filtered or pressed at least slightly and is classified as sake. Doburoku is not filtered, leaving rice grains in the liquid, and is classified as another type of brewed alcoholic beverage. Our nigori sake is lightly filtered through coarse cloth, giving it rich rice flavor and a smooth texture.

The best serving temperature depends on the sake. Fruity styles such as junmai daiginjo and nama sake are best served well chilled at around 5 to 10°C, often in a wine glass. Tokubetsu junmai and regular sake can be enjoyed chilled, at room temperature, or gently warmed to around 40°C, which brings out the natural umami and sweetness of the rice.

Sake lees are sold year-round at our direct brewery store. Fresh sake lees from the new brewing season are usually available around December. Because sake lees from handcrafted sake such as junmai daiginjo are very popular, please check our news page and official social media for seasonal availability.

The impression of sweetness or dryness in sake is mainly determined by the balance between sake meter value, which relates to sugar content, and acidity. Sake with more sugar and lower acidity tends to feel sweeter, while sake with less sugar and higher acidity tends to feel drier and crisper. We offer a wide range of sake, from clean dry styles that pair well with meals to sake with gentle rice sweetness.
