Rum does not need to be refrigerated, and in fact, it is generally recommended to store it at room temperature. Rum is a spirit with a relatively high alcohol content, typically around 40% to 50% alcohol by volume (ABV). This high alcohol content acts as a natural preservative, preventing the growth of bacteria and spoilage.
Storing rum at room temperature in a cool, dark place, away from direct sunlight and extreme temperature fluctuations, will help maintain its quality and flavor over time. Exposing rum to temperature extremes or direct sunlight can lead to changes in taste and possibly even damage the bottle or its cork.
Additionally, refrigeration might cause the rum to develop a cloudy appearance, but this does not mean it's spoiled or unsafe to consume. The cloudiness is often the result of certain compounds in the rum crystallizing at lower temperatures, and it should disappear once the rum returns to room temperature.
In summary, it's best to store rum at room temperature in a cool, dark place for optimal preservation and enjoyment.
