title_body: What's the effect of Chill-filtering on Whisky?
upvoted_answer: The main reason to chill filter a whisky is actually purely cosmetic
  
  
  Chill filtering is a process that makes sure that a whiskey won't go cloudy if water or ice is added to it.
  
  It is mainly only done as people don't want to see a cloudy whiskey so it is done a a cosmetic touch to make the whiskey more appealing. 
  
  Although if a whiskey is above 46% this process is not necessary as the alcohol level will stop the cloudiness from happening. 
  
  It is causing a bit of bother with whiskey distillers as people want a natural organic whiskey so they don't want it to go through the process of chill filtering but they also want a nice clear whiskey.
