Understanding Sake Shelf Life

Sake has no expiry date. The longevity of sake depends on its type and whether the bottle is opened or not. Here's a detailed look at how long sake lasts and how to store it properly.

No Expiry Date

Sake does not have an expiry date because alcohol doesn't rot. This is why you won't find an expiry date on a sake label. However, it's best to consume sake as soon as possible. Sake is usually shipped from breweries when it’s in the best condition. Unpasteurized sake like Nama zake and Nigori zake should be consumed as soon as possible. Treat these types of sake like milk: keep them in the fridge and enjoy them while they’re fresh.

Shelf Life of Unopened Sake

The shelf life of pasteurized sake varies by type:

• Ginjo Type and Junmai Type: 8-10 months
• Honjozo Type: 12 months

Shelf Life of Opened Sake

The shelf life of opened pasteurized sake is controversial. Some say it lasts a few weeks, while others suggest it can last a few months. Personally, I find that after one month, the taste changes significantly with more off-flavors, odors, and acidity.

Production Date

The recommended consumption periods start from the production date of the sake, not the purchase date. The production date (製造年月) is when the sake was made and is shown on the label.

Proper Storage

Proper storage is crucial for preserving the quality of sake. Poor storage conditions can shorten its shelf life significantly. Even a few hours in bad conditions can ruin the taste of sake. Sake is that delicate!
