title_body: Why is freshly roasted coffee better than pre-packaged coffee?
upvoted_answer: Coffe is a natural product, and has a shelf life. The changes made to store the product for a longer period, makes the coffee deteriorate.
  
  Coffee is at its best one week after roasting, and the shelf live is maximum 3-4 weeks after roasting. If the bag of coffee has a ‘best before’ or ‘use-by date’ rather than a ‘roast date’ it’s because whoever packaged the coffee would rather you didn’t know when it was roasted.
