What is the best way to store opened bottles of spirits?

Storing opened bottles of spirits in an upright position in a cool, dark place is the best practice because it helps maintain the integrity of the beverage. Keeping the bottle upright minimizes contact between the liquid and the cork, which can lead to cork deterioration and compromise the quality of the spirit over time.

Additionally, a cool and dark environment protects the spirits from light and temperature fluctuations, both of which can alter their flavor and aroma. This method preserves the original taste profile and prevents oxidation, ensuring that the spirit remains enjoyable for a longer period after being opened. The other options, such as refrigeration or exposure to sunlight, could negatively affect the spirits, making them less pleasant to consume.
