How Long Can You Keep Port Wine Before Opening

Port wine is a type of fortified wine that has been aged in oak barrels for several years. Its sweetness and flavor make it the perfect accompaniment to many meals and desserts, but how long can you keep port wine before opening?

Well, the answer depends on what kind of port you are storing, as well as where and how it’s stored. In this article, we’ll discuss how long different types of port can be kept before being opened and consumed.

Read on to find out more about proper storage techniques for keeping your favorite ports in top condition!

Types Of Port Wine

Port wine is a fortified red or white sweet, dessert-style wine produced in Portugal. It has been around for centuries and is one of the most popular after dinner drinks. Its unique taste comes from being aged in barrels made out of oak wood and having brandy added to it during its aging process.

There are several types of port wines available such as ruby, tawny, vintage character, late bottled vintage, crusted and LBV reserve. Each type has a distinct flavor profile with varying levels of sweetness that can range from dry to off-dry or medium sweet.

The length at which port should be kept before opening depends on the type of port you have purchased. While some ports are meant to be drunk immediately upon purchase, others require more time so they can reach their peak maturity level. Ruby ports generally need less aging than other varieties and can last up to 10 years if stored correctly.

Tawny ports tend to mature faster than ruby styles but will still benefit by being kept for 8-12 years prior to consumption. Vintage characters and LBVs usually have longer maturation times ranging anywhere from 12-20 years depending on the individual bottle’s production history.

No matter what kind of port you choose, proper storage conditions are essential for maintaining its quality over time. Temperature control needs to stay between 50°F – 58°F (10°C – 14°C) while humidity must remain consistently high at 75%-85%. These factors help ensure your port stays fresh until you’re ready to open it and enjoy!

Temperature And Humidity Needs

Temperature plays an important role in the preservation and aging of port wines; the ideal temperature for storage is between 55-65 degrees Fahrenheit.

Humidity is also important for the preservation and aging of port wines, as the ideal humidity for storage is between 70-80%.

In order to preserve the quality and flavor of port wines, it’s important to keep them in the ideal temperature and humidity conditions.

Temperature is also a factor when it comes to serving port wines; the ideal serving temperature for port wines is between 50-58 degrees Fahrenheit.

Humidity is also important for serving port wines; the ideal serving humidity is between 70-75%.

With the proper temperature and humidity conditions, the shelf life of port wines can be extended and the quality and flavor can be preserved.


Temperature is an important factor when it comes to storing port wine.

Storing the bottle at a cool temperature of between 8-12 degrees Celsius will ensure that the flavor and aroma of the port remain intact for longer periods of time.

This can be achieved by keeping the bottles in a dark, dry place away from direct sunlight or any sources of heat such as radiators.

However, if you are planning on drinking your port within two weeks then room temperature should be sufficient, though never store it near a window as exposure to light can damage its taste.

Ultimately, taking proper care with regards to temperature will help keep your port tasting great for all occasions!


So now that we’ve discussed temperature, let’s move onto humidity.

It’s important to remember when storing port wine that the environment should have a low humidity level, as too much moisture can cause spoilage due to mold and bacteria growth.

The ideal relative humidity for storage is between 50-70%, so if you’re looking to store your bottles long term then it may be worth investing in a humidor or some other form of airtight container with a built-in hygrometer.

Just make sure that whatever you use has proper ventilation because stagnant air won’t allow moisture to escape and will eventually lead to damage.

On the other hand, too little humidity can also dry out corks which could ruin the taste of the port over time.

So try not to go below 40%.

This way all your bottles stay safe and sound, regardless of how long you plan on keeping them!


Now that we know the optimal temperature and humidity for storing port wine, let’s discuss some of the best ways to store it.

Firstly, a cool dark place is ideal as light can cause oxidation which will ruin the taste of your precious bottles.

Secondly, make sure whatever you use has proper ventilation as stagnant air won’t allow moisture to escape and could eventually lead to damage.

Finally, if possible invest in an airtight container with a built-in hygrometer so you can keep track of the relative humidity levels within your storage space – this way all your bottles stay safe!

Storing In Casks

Port wine, which is typically a fortified sweet red or white wine, can be stored for long periods of time. Casks are the preferred method of storage and have several advantages over other methods:

  • Port wines in cask age slowly and evenly as they are exposed to oxygen through small pores in the wood.
  • The aging process allows the flavor components contained within the port to develop complex characteristics that would otherwise remain dormant.
  • As most ports are ready to drink upon release from their casks, no additional aging needs to occur after bottling.

The porous nature of casks also helps protect against spoilage by preventing excessive oxidation due to exposure to air. With proper care and maintenance, ports should last indefinitely if left in their cask; however, once opened, it’s best to consume them within two weeks for optimal freshness and enjoyment.

From here we move on to storing port wine when bottled…

Storing In Bottles

Port wine can be stored in its bottle for up to two years without any significant degradation of flavor. It should be kept away from sunlight and sources of heat, as well as being continually laid down at an angle. This will ensure a good seal between the cork and bottle, preventing air from entering and oxidizing the port over time.

It is not recommended that you keep opened bottles of port for more than three days due to oxidation. After this period, it may become too bitter or lose its intended flavors entirely. To maximize freshness, it’s best to use the entirety of the opened bottle within one day if possible.

For storing unopened bottles longer-term, it’s wise to consider investing in a cool cellar or other temperature controlled environment – though many people opt just to store their port on shelves in their pantry with no ill effects.

Moving forward, we’ll explore how to properly open and drink port wine.

Properly Opening And Drinking Port Wine

Port wine can be kept for many years if stored properly. It should be placed in a cool, dark place with minimal temperature variation and away from direct sunlight. The bottle should then be laid on its side to prevent the cork from drying out. Once opened, it’s best to drink port within two weeks of opening.

To open port correctly, you’ll need an opener designed specifically for wines sealed with corks. Begin by cutting off the foil at the top of the neck using your thumb or sharp scissors. Then insert the pointy end of a waiter’s friend into the cork and gently turn until it is almost all way down – don’t go too far! Handle with care as this will help minimize potential damage to the cork which could result in oxidization. Finally, slowly pull up on handle while keeping pressure on the cork so that it comes out cleanly and does not crumble apart.

When serving, pour small amounts at a time into glasses that are wide enough for oxygen to interact with the liquid and make sure everyone has their own glass – sharing increases risk of contamination from bacteria such as saliva and germs from sicknesses like colds or flu.

Port tastes great when drunk chilled but room temperature also works well depending on preference; however regardless of temperature choice make sure you savor every sip because even after careful storing port quickly loses its complexity once uncorked.
