Plum sake, also known as umeshu, is a type of sake that is infused with plums or plum extract. The addition of plums gives it a distinct fruity flavor and aroma. When it comes to storing plum sake, there are a few factors to consider.
Firstly, it is important to note that plum sake has a lower alcohol content compared to regular sake. This lower alcohol content, combined with the presence of plums, makes plum sake more prone to spoilage. Therefore, it is generally recommended to refrigerate plum sake to extend its shelf life.
Refrigerating plum sake helps to slow down the aging process and preserve its flavor. The cool temperature of the refrigerator helps to inhibit the growth of bacteria and other microorganisms that could potentially spoil the sake. Additionally, refrigeration helps to maintain a consistent temperature, preventing fluctuations that could negatively affect the quality of the plum sake.
It is advisable to store plum sake in the refrigerator at a temperature between 32 °F and 41 °F (-2 °C to 5 °C). This temperature range is ideal for maintaining the freshness and flavor of the sake. However, it is important to avoid freezing plum sake, as this can alter its taste and texture.
To further protect plum sake from spoilage, it is recommended to keep it tightly sealed. This helps to prevent exposure to air, which can lead to oxidation. Oxidation can cause the plum sake to lose its flavor and become stale. Keeping the bottle tightly sealed also helps to maintain the aroma and freshness of the plums infused in the sake.
Refrigeration is the best way to store plum sake. The cool temperature helps to preserve its flavor and extend its shelf life. Remember to store plum sake in the refrigerator at a temperature between 32 °F and 41 °F, and keep the bottle tightly sealed to prevent oxidation. By following these guidelines, you can enjoy your plum sake at its best for a longer period of time.
