How to Store and Preserve Sake
Sake changes its color and flavor over time, especially when exposed to direct light and fluctuating temperatures. Therefore, the best way to store sake is in a dark and cool place. With proper care, most sake usually keeps its intended flavor and color for up to a year. However, certain types need more precise temperature control.
Sake drinkers preserve sake similarly to how they store wine, most commonly in a refrigerator, but a cellar also works well. One major difference to wine is that sake bottles are not corked. Because of this, unlike with wine bottles, humidity does not affect the quality of the sake, and it is recommended to store the bottles upright.
