Why whiskey bottles are kept upright?

Store whiskey in an upright position. The way in which bottles are placed will affect the quality and condition of the whiskey. Unlike corked wine, which needs to be stored horizontally, whiskey is recommended to be stored upright. Whiskey corks can be used multiple times. Whiskey corks do not expand, so their sealing properties are not as good as red wine corks. It should not be in contact with wine for a long time, because over time, the high concentration of alcohol in whiskey will degrade the cork, causing it to break and contaminate the wine.
