Many people would settle for a pack of coffee bought in a corner grocery store. Why bother grinding your own coffee, they say, when someone had already done it for them?
The answer to this is that freshly ground coffee beans produce a stronger flavor than your average pack of coffee that's been sitting on a shelf for a month or so. Ground coffee tends to absorb foreign odors, which may ruin its taste. So, the less time passes between coffee being ground and brewed, the more enjoyable is its flavor.
Thus, a coffee grinder is something that a true coffee fan must have!
