Green coffee in general can be stored up to one year from the date of processing with no noticeable changes in flavor. Bright, delicate coffees can fade faster; earthy coffees can last a bit longer. Very often the type and quality of the processing methods used on the coffee will determine how long a coffee will hold up. For example, "Miel" or pulped natural processing very often shortens the storage life of a coffee - you will see changes in flavor sooner and in a more pronounced way than with other processing methods. Coffee ought to be stored in a cool dry place, ideally in a breathable container like burlap, or cotton. For a hundred years or more coffee has been transported the same way, in large burlap or jute bags. More recently, producers have experimented with vacuum packaging and storage in special multi-layer poly bags to extend the life of the coffee. It has been more recently that Storage has become a greater factor in the processing chain of coffee.
