Can Whiskey Go Bad?

We need to consider specific criteria like quantity in the bottle, where it is kept when we talk about this.

  • Quantity: When a whiskey bottle is opened, and half of it is finished, then for one or two years, it won’t go bad. But when it has less quantity left or less than half, it can go bad in six months. When a bottle is empty when half is finished, oxidation can occur, and whiskey can go bad or taste better. To avoid this, you can take small containers and transfer whiskey into them so less oxygen will be there.
  • Place where it is kept: When you keep in sunlight, whiskey can evaporate. Sometimes rays from the sun can even break the whiskey, so the whiskey’s flavor can also come down.
