Whole bean or ground coffee can be quite the debate among coffee connoisseurs, with both sides of the story having some positives and negatives. Most people buy and use ground coffee, mainly because that is the easiest to use and the form that is found on the shelves of every local supermarket. It's ready to brew, and won't require any extra time, skills or equipment on your part. And that pretty much sums up all the positive aspects of pre-ground coffee. Ease and convenience.
