title_body: How is instant coffee made?
upvoted_answer: How instant coffee is prepared in the factory:
  
  
  Coffee beans are roasted
  They are ground very finely (0.5 mm - 1.1 mm in diameter)
  The ground coffee is mixed with water in percolation columns which reaches 155 - 180 degrees Celsius.  This is the extraction process.
  This mixture is then concentrated and/or dried using vacuum evaporation, freeze drying, or spray drying methods.
  
  
  The result from this is what you get in the store.
