title_body: How can I keep Whisky from corking over time?
upvoted_answer: Hard spirits naturally degrade over time once opened
  
  You've already opened the bottle because you wanted to actually enjoy the drink, here are step you can take to help ensure the slow and unstoppable flavor degradation takes as long as possible.
  
  
  Store out of the light in a cool and dry place. 
  
  
  A good general rule of thumb for just about any type of alcohol is to store the bottles in a cool, dry, and dark location this will prevent any fluctuation in the environment from causing changes and prevent UV radiation from getting in. 
  
  
  Keep the bottle completely sealed.
  
  
  Whiskey and other spirits will not mature like a wine in a bottle over time, in fact using an open cork will likely contribute to the breakdown of the flavor as the spirit will have more opportunity to oxidize. A proper rubber stop/cork will do the job just fine. 
  
  If you are looking to "age" a whiskey your best bet would be to store it in a small used whiskey cask or in a sealed class bottle with whiskey cask staves added. Both will allow the whiskey to absorb more flavors over time.
