How Long Do Wine Kits Last?

Home winemakers often wonder if that old wine kit that has been sitting in the basement is still good. Can you still produce a drinkable wine from a kit that is several years old? Is it even safe to drink the wine from an old wine kit?

In this post, we’re going to answer the question: How long do wine kits last? We’ll take a look at the durability and shelf-life of wine kits and discuss how long you can keep them before fermenting.

If you’ve ever been curious about the shelf life of a wine kit, then keep reading.

Do wine kits have a shelf life?

Wine kits are usually considered to be food products. Food products usually have to have an expiration date printed on the packaging somewhere. However, you may find that some wine kits do have an expiration date printed on the box, but many do not.

If you’re not finding a date on the outside of the box, take a look inside at the ingredient package. Many times you can find the date on the yeast packet or juice container.

Most wine kits should be used within 12-24 months

Wine kits don’t expire in the same way as some perishable food items. They won’t usually spoil or become unconsumable like a dairy product. Usually, the quality of the juice that produces wine can be compromised over time but the kit can still be safe to drink.

Can I still use a wine kit if it’s past the expiration date?

In general, yes you can use a wine kit that has passed its expiration date. There are a few things to consider before dusting off that old wine kit, however.

The quality of the ingredients contained in the wine kit can degrade over time. This can lead to the finished product being a subpar wine that can even have off flavors. Depending on your pallet you may or may not notice the difference in the finished wine quality.

The juice itself can go bad, however, most of the juice shipped in wine kits has enough preservatives to keep that from happening. I’d be more concerned about the other ingredients going bad, such as the yeast, additives, and fining agents.

You may need to replace some of the ingredients if the wine kit has not been stored properly.

How can I tell if an expired wine kit is still good?

As we mentioned above, you should try to use wine kits within 2 years. If you have a kit older than this, it might still be ok to use. You need to give it a very basic test to ensure that the juice is still good. You can smell the juice to see if it still smells OK. If it passes that test, you can taste a bit. It should taste like a very sweet juice.

If you notice any off smells or tastes, then you should dispose of the kit. However, if everything seems ok, you can probably still produce a drinkable wine using the kit.

The next thing to do is check the ingredients. One thing to note is the conditions that the kit was stored in. If it was in a cool and dry place, then it’s more likely that the ingredients are still usable. You’re going to want to consider whether or not you want to replace the ingredients based on the length of time the kit has sat passed its expiration date and the storage conditions.

Here are a few things to look for:

How to tell if the yeast is still good

Yeast is a living organism that can lose its viability over time or even die off. It’s important for yeast to be stored in cool and dry places to ensure its longevity. Yeast can last over a year if stored properly.

The yeast should be dry and free of clumps. It should also smell similar to a bakery. If your yeast has been exposed to excess moisture, it may be caked together. You’re not going to want to use that yeast.

If the yeast is old, I would recommend using a yeast starter. This is when you combine the yeast with a small amount of wine juice, or some warm water with sugar, in a small container and let it grow for a few days.

You want to give the yeast a good environment to grow in. You can tell if the yeast is active based on the fact that the juice is bubbling and the yeast is expanding.

If it is active, you can use the yeast starter to make your wine. If not, then you’re going to need to find a new packet of yeast to use.

How to tell if the wine additives are still good

Wine kits can come with many different additives to help you produce a decent wine. Some of the more common additives are potassium metabisulfite, potassium sorbate, tannins, and acid blend. Other things such as grape skins and wood chips might even be included.

The first thing to do is check for expiration dates on the individual ingredients. If they are passed the date, they may not be as strong as they would be if fresh. You can always give ingredients a smell test just to make sure there is no off odor detected.

How long can Potassium Metabisulfite and Potassium Sorbate last?

Potassium metabisulfite and potassium sorbate can last around 3 years or more. Both of these ingredients are important for stabilizing the wine.

Potassium Metabisulfite is a preservative and antioxidant. It helps keep your wine from oxidizing, which will make the wine taste poor.

Potassium Sorbate is another type of preservative, but it has a different job. It keeps the fermentation process from restarting once you bottle your wine. If the fermentation process were to restart, you would have corks popping out of the bottles due to the pressure of the gas being released.

If you suspect that either ingredient is bad, they are relatively cheap to replace.

Can tannins still be used if they are old?

Many wine kits come with powdered tannins that can be added to give the wine body, taste, and mouth feel. Dry tannins can also last for 2-3 years and still be used.

How long do woodchips last?

The wood chips found in wine kits can last a long time if stored properly. If they are in a plastic bag, they will probably outlast any of the other ingredients in the kit. However, you might lose a little bit of the oak flavoring the longer the wood chips sit.

Can wine skins last past expiration?

If your kit comes with wineskins, then it is probably a high-end kit. The wineskins are used in the primary fermentation process when making red wines. This makes the kit as close as possible to the process a commercial winery would use.

This is probably one of the most perishable items in a wine kit. I would check the packaging for off smells. If there is any off smell, just get rid of them and ferment the juice without skins. You can still produce a decent wine without the skins as many kits do not include grape skins.

As you can see, wine kits can often be used after their expiration date, but you want to check each ingredient to be sure that it is still usable.

How should a wine kit be stored?

If you’re not planning to use your wine kit immediately, then proper storage is important. A wine kit needs to be stored in a cool and dry place. It’s even better if the place is dark. You want to avoid exposing the kit to direct sunlight or extreme temperatures. A temperature slightly below room temperature is ideal. You don’t want it much colder, but colder is better than warm.

You also want to keep the kit away from any strong odors that might be absorbed by the ingredients, even though the ingredients should be protected by plastic. The ingredients should all be tightly sealed to prevent contamination and damage to the contents.

What to do if you suspect your kit is bad?

If you have any thoughts that your kit might be bad, it’s best to buy a new kit. As we mentioned before, there is not really a risk to making wine that would make you sick, but the results you get may not taste very good.

There are several options on the market for wine kits, here are some of our favorite picks:
