What is the shelf life of sake?

The correct answer indicates that the shelf life of sake can vary depending on its type and storage conditions, generally falling into the range of several months to about a year.

Sake is a brewed beverage that is subject to oxidation and spoilage over time. An unopened bottle of sake typically has a shelf life of around 1 year if stored in a cool, dark place. However, once opened, the sake should ideally be consumed within several months to ensure the best flavor and quality since exposure to air can lead to deterioration.

Both the durations mentioned in the options reflect different scenarios: one for unopened sake and the other for opened sake. Proper storage is crucial for maintaining the quality of sake, and the nuances of its shelf life highlight the importance of understanding how to preserve its flavors. This reason supports the conclusion that answer D, which encapsulates both the 6 months and several months, is accurate for the varying conditions of sake storage.
