How to tell if sake has gone bad for unopened bottles?

This is a tricky question because there is no real way to tell unless, of course, you have a good familiarity with the taste of the bottle in question.

You probably checked for the expiration date on the back and didn’t see one. Well, that’s because sake brewers in Japan, unlike their alcohol-producing Western counterparts, do not put expiry dates on their products.

Why is that? Because under Japanese law, it’s not required to put expiration dates on certain types of alcoholic beverages. And that includes, you guessed it, the very bottle of sake you are staring at and doubting right now.

However, there is some good news, and it has to do with the reason why Japanese law decided to forego the expiration date you so desperately seek. It’s not because it remains eternally fresh, in case you’re wondering, but rather because no matter how old that bottle of sake is, it will never kill you or make you sick.

If you still don’t want to drink it unless you know for sure whether or not the bottle has expired, despite this bit of good news, then I will share a little trick.

There is actually a date on the back of your bottle – although not an expiration date. Instead, it’s the date that the sake was bottled. Sometimes brewers store their sake for a certain period before bottling, so it’s not an accurate indication of the actual age of the sake, but it’s as close as you’re going to get in determining the age.

You will obviously need help in reading the expiration date because it’s written in Japanese unless you are already fluent. No? I didn’t think so. Here is a guide on how to read Japanese dates.

Got the date? Great.

Has it been one year or less since your sake was bottled? If so, you’re all set. It might even still be fresh after two years if you stored it in a cool place.

Sake oxidizes fast, so once opened, it goes bad in about a week. It’s best to finish it within three days of opening.

A natural reaction most people will have is to throw it out. You do not necessarily have to do this because, as mentioned, there are no harmful effects from drinking it.

What you can do is try heating it a bit and see if that improves the taste – even if it is a cold premium bottle.

If you still do not enjoy the taste after heating it, then why not use it for cooking purposes instead?


How to store sake correctly

Correctly storing sake can significantly increase its shelf life. Doing so is especially important when dealing with the more expensive premium brands. Also, keep in mind that an unopened bottle will stay fresh for at least a year compared to a week for an already opened bottle.

Keep away from light:

Exposing your bottle to the light, especially ultra-violet light, is probably the single worst thing you can do. Light causes an undesirable chemical reaction with the protein contained in the sake, which leads to it going bad long before its due date.

Fortunately, an ever-increasing number of brewers are adding a green or brown tint to their bottles to help minimize the damaging effect direct light can have on their product. But still, great care should be taken, and the best way to do this is to store your sake in a cool, dry, and, more importantly, dark place.

Keep it away from heat:

Any heat has a negative effect on perishable items, and this holds especially true when it comes to sake. Keeping your bottle chilly is ideal, otherwise at room temperature.

Keep the bottle in its box:

In most cases, when you buy a bottle of sake it will come in a box. Most people upon purchasing it will discard the box because, in most cases, the actual bottle looks far prettier than the packaging.

Try not to do this unless you are planning on drinking the whole bottle soon because the actual box provides an additional layer of protection from the damaging effects of light.


Can I store sake in the fridge?

Most types can be kept in the fridge for short periods. For longer-term storage, it would be better to keep it in a cool and dry place. The only type of sake you absolutely have to store in the fridge, whether long or short term, is namazake (unpasteurized sake).


Conclusion:

Sake can and does go bad, very easily, in fact. Minimize this by storing it correctly and by consuming it within 1 to 2 years from its manufacturing date. If your bottle has indeed gone bad, try heating it and see if that makes a difference to the taste. If still not pleasurable, then rather use it for cooking instead of throwing it out.
