The traditional method of storing wine is lying the bottles down horizontally. This position ensures that the cork remains in contact with the wine, keeping it moistened and preventing it from drying out. When the cork dries out, it can shrink and let air seep into the bottle, resulting in oxidation that can spoil the wine’s flavor and quality.
However, port wine differs from regular wine in some key aspects. Firstly, it has a higher alcohol content, usually ranging from 18% to 20%. This higher alcohol level acts as a natural preservative, making port wine less susceptible to oxidation. Secondly, port wine is often aged in oak barrels before bottling, which adds additional protection against oxidation.
Considering these factors, many experts suggest that storing port wine upright is a viable option. By storing the bottles upright, you eliminate the risk of potential leakage or seepage from a moistened cork. This is particularly relevant for vintage ports, which tend to have older corks that might be more prone to deterioration.
Another important consideration is the type of port wine you have. There are two main categories: “vintage” and “tawny.” Vintage port is often aged in the bottle, while tawny port is aged in oak barrels and then bottled. Vintage ports benefit from lying down because they undergo further aging and development in the bottle. On the other hand, tawny ports typically do not require further aging in the bottle and can be stored upright.
Temperature and humidity also significantly impact the storage of port wine. Ideally, port wine should be stored in a cool, dark place with a stable temperature of around 55-60°F (12-15°C). Excessive heat can speed up the aging process of the wine, potentially altering its flavors. Additionally, the humidity level should be around 70%, as it helps to prevent the cork from drying out.
Regardless of whether you choose to store your port wine upright or lying down, it is essential to handle the bottles with care. Avoid excessive movement or shaking, as this can disturb the sediments and impact the quality of the wine. Also, keep in mind that once a bottle of port wine is opened, it should be consumed within a few days to maintain its optimal taste.
In conclusion, the debate between storing port wine upright or lying down boils down to personal preference and the type of port you have. While the traditional method suggests lying down the bottles to keep the cork moist, the higher alcohol content and oak aging of port wine make it less susceptible to cork deterioration. Factors such as the type of port, temperature, humidity, and careful handling should also be considered when storing this delightful wine. So, choose the storage method that aligns with your situation and enjoy a perfectly aged glass of port wine whenever the occasion calls for it.
