For at least a year, homemade wine can stay on the shelf without additional steps. The longevity can be extended to two years or more if you store it out of light in an area with no temperature fluctuations. Sulfites are a natural byproduct of the fermentation process.
They are found naturally in many fruits and vegetables, including grapes, apples, pears, peaches, plums, apricots, cherries, blackberries, blueberries and many others. Sulfite levels in wine vary widely, depending on the type of wine and how it was made. For example, red wines have higher levels of sulfite than white wines, while white wine has lower levels than red wine.
In addition, wine made from red grapes has a higher sulfate content than wine from white grapes. This is due to the fact that the red grape skins contain more sulfur than the white grape skin, which contains less sulfur. The sulfur in the skins is converted to sulfuric acid by the yeast.

How do I know if my homemade wine is bad?
If a wine is excessively nutty or smells of bruised apple, smells of nail polish remover or acetone, has turned brown, has become substantially fizzy, and smells like wet dog or wet cardboard, it’s time to call it quits. Wine that has been stored in the refrigerator for more than 24 hours should not be consumed.
How do you preserve home made wine?
Use good quality glass bottles; we strongly suggest not using plastic bottles. Synthetic corks can cause problems, so use a natural cork. Store in a cool, dry place.
Does homemade wine go bad in the fridge?
With the bottle re-corked and kept in the fridge, this slows down the oxidation process, keeping the wine fresh for up to five days, although you should probably finish the bottle within three days of opening it.
Can you drink homemade wine after 2 weeks?
If everything goes well with your ferment, you can drink your wine at any point. The longer you leave it, the more sugar the yeast will turn into alcohol until one of two things happens; either the sugar runs out, or the amount of alcohol in the wine increases.
Is it safe to drink old homemade wine?
Old homemade wine is safe to drink but can be unpleasant to taste. Wine does not expire in the same way as food. Rather than being completely bad, it simply loses some of its properties.
Homemade wines are also a good source of vitamin C, which is important for the health of your skin and eyes. C is also found in many fruits and vegetables, so it’s a great way to get your daily dose of the vitamin.
Can bacteria grow in old wine?
Clostridium perfringens and some Oenococcus species in wine can form undesirable aroma and flavour compounds as a result of their growth following malolactic fermentation. AAB species are more resistant to food poisoning than others. In the case of A. boulardii, it is considered to be the most spoil-tolerant of all the species.
This is due to the fact that it does not produce any of the undesirable compounds that are produced by other species, such as acetic acid and phenolic acids. It is also resistant to a wide range of yeasts and bacteria, making it an ideal candidate for use in winemaking. However, this is not to that all strains are equally suitable for wine production.
For example, some strains may not be able to ferment at all, while others may be more suited to certain types of wine.
