Sake Guide Lesson 5: How To Properly Store Sake

Sake is brewed with great care and thought. Proper storage and handling is absolutely essential to enjoy sake at its best. Though you might be tempted to treat it like a bottle of wine or liquor, it is a category all its own. Read our tips below on how to store your sake as soon as it arrives.

Storing temperature isn’t always the same as serving temperature

One of the reasons sake is such a unique beverage is that it can be enjoyed at different temperatures. Depending on the bottle, it can be served over ice, cold, room temperature, warm or hot. It is often the case that one sake can be drunk many different ways, yielding different impressions at each temperature. Sake that was previously stored in the fridge can be enjoyed at room temperature. Likewise, sake that was maintained at room temperature can be consumed chilled. When we talk about storing temperature, we’re talking about the best way to keep the sake’s flavor and aromas from deteriorating over time.

Storing temperature for different types of sake

Sake category is the best indicator of how to store it. On the bottle, look for words like junmai, ginjo, daiginjo, honjozo, futsushu, nama, nigori or sparkling. These identifiers can inform you how delicate the sake is; delicate sake should always be refrigerated even prior to opening.

Sake types to refrigerate before opening

What makes one sake more delicate than another? Rice polishing, pasteurization and fermentation are all factors. Let’s take a look at the sake types you should refrigerate before opening.

Ginjo and daiginjo sake

Sake made from rice that has undergone a greater degree of rice polishing is more delicate. Ginjo is a category of sake that has a rice polishing ratio of 60% or less, meaning only 60% of the rice grain remains. The rice polishing ratio of daiginjo is 50% or less. The smaller the number, the more the rice has been polished. Ginjo, junmai ginjo, daiginjo and junmai daiginjo should always be refrigerated.

Even if the label says the sake can be served at room temperature, store it chilled until you plan to open it to preserve its flavor. Take it out of the fridge a few hours ahead of serving time, or start by sipping it cold and gradually let it reach room temperature as the evening progresses.

Nama sake

If you find the word “nama” on the bottle, put it in the fridge ASAP. Nama means “unpasteurized” in Japanese. Typically, sake is pasteurized (heated up) twice to stop fermentation in the traditional brewing method. The reason for this is to make it more shelf-stable. However, many breweries produce unpasteurized sake because of its fresh and dynamic flavor. The vibrant taste of nama is very popular, and many breweries release limited-batch seasonal nama throughout the year. In nama sake, microorganisms like yeasts are still alive, which means that there is a greater risk of flavor change when exposed to warm temperatures or the passing of time. To keep its original taste, you should store it in the fridge because microorganisms hibernate at temperatures lower than 40 F.

Being so delicate, the best way to experience fresh, lively nama sake is to drink it at or near the brewery. There are sake breweries in the U.S., such as Brooklyn Kura and Farthest Star Sake, where you can drink fresh nama sake on tap, but when importing from Japan, it gets a bit trickier. In 2026, Palate Project undertook this monumental logistical challenge with the Fresh From Brewery project — an unprecedented service that provides cold transport of nama sake from Japanese breweries all the way to your door.

We want American drinkers to soak up the revitalizing, unbridled flavor of this special sake without having to book a plane ticket. By keeping it cold during the entire journey overseas, at the port, to our warehouse, and expedited to your door, we can get you as close as possible to that life-changing, fresh-from-brewery taste.

Sparkling sake

Just like any other carbonated beverage, sparkling sake is sensitive to heat and pressure. It should always be refrigerated, which is easy to remember because you’d only drink it cold anyway. Be sure to keep it from getting too cold — for example, by putting it in the freezer — as this could cause the bottle to burst. Always open sparkling sake slowly and gently, and avoid shaking it. Lastly, just like Champagne or sparkling wine, it’s best to finish sparkling sake soon after opening, as leaving it in the fridge for days will make it turn flat.

Nigori and flavored sake

Nigori or cloudy sake is another style of sake that is almost always drunk cold. What makes it cloudy are the leftover rice lees from the brewing process, giving the sake a milky color and texture. Refrigeration keeps these rice particles from spoiling. Similarly, fruit-infused sake such as yuzu sake should be kept refrigerated, as they contain real fruit.

Sake types that don’t need to be refrigerated before opening

When in doubt, it’s best to refrigerate sake. However, junmai, honjozo and “futsushu” (table sake), are typically OK to store at room temperature in a cool, dark place. These sake types do not undergo as much rice polishing, and often have richer, more robust flavor profiles. “Koshu” (aged sake) is also safe to store this way prior to opening.

Things to avoid when storing sake

No matter where you store your sake, there are three things to pay attention to:

1. Ultraviolet light: Keep your sake away from direct sunlight. If possible, LED light is recommended rather than fluorescent light.
2. Temperature change: Even if a place is usually cold, it’s best to assume there will be temperature changes by a stove, next to the fridge, or anywhere else there is a heater or frequent door opening. Find a dark, cool and stable place.
3. Strong smells: Some sake and their bottles can be affected by strong smells. Do not store near strong-smelling foods such as garlic, onion, etc.

What to do after opening a bottle

You’ve opened your bottle and enjoyed it with your meal! Now, how should you store sake after opening? Is it necessary to finish a bottle all at once?

We recommend putting all sake, no matter what kind, in the fridge after opening. When it comes to how long it can stay there, it varies. Nama is best consumed immediately or within a few days of opening. Most other sake can stand for a week or longer. The rule of thumb is to drink sake young.

When does sake expire?

Sake bottles only show production dates. Although sake does maintain its flavors for quite a long time under proper storing conditions, over time, it may gradually lose some of its intended flavor and flavor balance. Many sake can last up to a year when stored properly and unopened. Learn more about how to tell if sake goes bad.
