How long is the shelf life of homemade wine?

In fact, in many places in my country, families have the habit of making their own wine. They use various crops to make wine, such as sweet potatoes, corn, wine, etc. Have you ever made wine yourself? I have made wine by myself by adding strong liquor to washed grapes. The effect is pretty good. It tastes pretty good. I believe everyone will definitely try it if they are interested. Do you know the shelf life of this kind of homemade wine?

Shelf Life of Homemade Wine (1) Homemade wine is generally not as well sealed as wine from a professional winery, so its shelf life will certainly be a little shorter. Generally speaking, 1-3 years is considered a long time.
