What is the Shelf Life of Sake?

Most sake bottles don’t have the best-before date printed on the label because it is not a requirement. However, you will only find a production date printed on the label, and it is the date when it was bottled.

Unlike wines and whiskies, sakes are not good for aging. So, it is necessary to consume freshly prepared or bottled sake. People must consume the sake within one or two years of bottling.

The actual shelf-life of sake is much longer, but it starts degrading with time. It means that the longer you store sake, the worse its quality will be. An unopened bottle of sake stored in the pantry remains safe for consumption for up to six years. But the quality may suffer from such a long storage.

After opening, things change. So, you must prefer consuming it within 24 hours of opening for the best taste and quality. If it is not possible, refrigerate it to maintain its taste and quality for up to a week.

Please note that the taste and flavor change over time, and you will experience a softer taste in your old sake. The pace of taste change depends on the quality of the sake. Some taste fresh for up to a week, while others may sustain their quality and taste for a month.

Unopened Sake Two Years
Opened Sake Two to Four Weeks
Unopened Unpasteurized Sake Six Months

What are the Spoilage Signs of Sake

Sake is a favorite delicacy in Japan, owing to its unique color, taste, and aroma. Technically, sake won’t go rancid, but its taste and flavor change with time. So, before consuming the beverage, you must check for the spoilage signs to know if it is still good for consumption or has gone bad.

Color Change

Sake is sold as a clear liquid or creamy white beverage in a bottle. However, the color changes with time, and it starts getting yellow tints once it goes off. The yellow tint indicates that the oxidative process has started and may cause a color change in the beverage.

Pungent and Unpleasant Smell

As mentioned, the unique characteristics of sake are its soothing aromas. There is science involved in brewing sake, and the unique aroma is achieved carefully. But, when your sake starts getting bad, it releases a rancid or pungent smell and indicates that the sake has gone bad.

The pungent or rancid smell starts developing when sake is stored inaptly, and oxidation has caused it to go off. It is best to discard the sake at this point.

Presence of Articles

If you see particles floating on the surface of the beverage or sitting at the bottom, it means the sake has gone bad, and it is time to discard it. However, it doesn’t mean that the beverage is not safe for consumption, but you won’t experience the unique aroma and taste you enjoyed when it was fresh.

Taste Change

When the taste of your sake starts getting funny and not like regular sake, the beverage is no longer suitable for consumption. You must discard the sake if you notice the unpleasant or funny taste.


What Happens If You Consume Bad Sake?

As mentioned, sake has no expiry date, and it keeps its quality for more than a year. Sake that was brewed a long time ago causes no harm if you drink it, provided that it is properly stored. However, the taste of the beverage will change with time.

If the smell is fine and the bottle is sealed correctly, you are unlikely to get sick after drinking the old sake. Even if your sake has a strange smell, discoloration, or quirky taste, it is safe to drink as no harmful bacteria enter the sake and make it unsafe.

If the cap leaks and the taste worsens, discard the beverage as it is no longer safe for consumption. So, always look for the spoilage signs before using the old bottle of sake.

Can You Freeze Sake Refrigerated Vs. Shelf-Stable

Unlike other beverages, sake is not suitable for freezing. The beverage has a proof of 14-18, which means freezing the sake may cause a change in the chemical composition when thawed. The Sake remains safe and edible, but the extreme temperature of a freezer will affect the unique flavors and aromas of the beverage.

Since the beverage comprises yeast, there is no need to freeze the sake. The presence of yeast prevents the bacteria from invading the drink, giving the drink a longer lifespan. Sake is already fermented, and hence it needs no freezing to preserve its taste and flavor.

However, the unpasteurized sake would require refrigeration immediately after opening the bottle.



Depending upon the sake you have bought, the requirement to refrigerate varies. The unopened pasteurized bottle of sake can keep for up to ten years and needs no refrigeration. It can be stored in the pantry in a cool and dark spot.

The pasteurized opened bottle of Sake will keep its quality for up to one month, and it must be stored in a fridge to preserve it. The unpasteurized bottle of sake can keep up to six months, and after opening, it only lasts for one to two weeks in a fridge.



As mentioned earlier, sake is a fermented beverage, and hence it needs no refrigeration. The pasteurized unopened bottle of sake can keep its quality for up to two years, even when stored outside a refrigerator.

The regular sake is pasteurized unless stated on the label. The pasteurized opened bottle of Sake lasts only for two to three weeks, but it needs consistent refrigeration.

The unpasteurized bottle of sake is different from regular sake, and it lasts for six to seven months. But, it must be stored in cool and dark places in your pantry. Keeping it outside the fridge will accelerate the deteriorating process, and it starts spoiling within four hours.
