While coffee beans may last for up to 6-12 months after roasting, it is generally acknowledged that for maximum flavour and aroma you should use whole coffee beans within 4-6 weeks of roasting.
So 4 – 6 weeks post-roasting date is the great-taste period. But if you have purchased a large bag of coffee beans and it takes longer to use them, be assured they don’t expire and go bad.
You will, however, start to notice a change in the depth of flavour and a lessening of the coffee aroma. The oils that carry much of the flavour dry out and the quality is affected. The older the coffee beans are, the less flavour they will have.
Our best tip for enjoying fresh whole bean coffee is to buy and grind and consume small coffee quantities regularly.
