A whole bean will give you the freshest cup as you can grind it at the time use. If you don't have a grinder or do not want to take the time to grind it yourself then look for a ground coffee that comes in a foil sealed bag with a valve hole in the bag (like all of our bagged coffees do). This helps prevent a coffee from going stale before you even open the bag.
Once you do open the bag be sure to store the coffee in a sealed opaque jar or container and use within a week or two for best taste and always store at room temperature. Purchase you coffee in smaller size bag amounts, we sell all of our coffees in 12oz sizes so there is no waste in stale coffee after being opened and unused.
