How to Keep Your Coffee Fresh

We never think that something which makes up part of our every day is far more delicate than we realise. Keeping coffee fresh requires a little consideration for how to store it properly.

    Understand how easy it is to let coffee go stale after roasting. From the day coffee is roasted, if not packaged properly and looked after, it doesn't last long. Some say a week, some say a month or two or three. This is because from the moment coffee is roasted it begins its aging process. Coffee beans get their best flavour and aromatic properties from the oil they contain. After roasting, these oils come to the surface and are evaporated, taking much of the flavour and aroma with them. It is via this process that the beans ‘stale’ or begin to dry. The less surface area exposed to air, the longer it takes for the flavour to deteriorate.

    Notice how freshly roasted coffee comes in a puffed up bag. This is because the beans have been properly packed and are still alive and fresh, the gasses are making their way out and causing the bag to puff up. For this reason, look for coffee bags that use a one way valve and have vacuum and oxygen-free packaging. This slows down the deterioration process.

    Check the roasting date of the beans before purchasing. Freshness of coffee begins as soon as it was roasted and ground and this bears a direct relation to the final taste test, for this reason is so important to always check out the roasting date of the beans.
    • Grind only what you need. Ground coffee has an even shorter use-by date. From the moment coffee is ground it will be at its freshest and best for around ten minutes; that means that the best time to use the freshly ground coffee is immediately. For this reason, for the best results you should grind only enough coffee required for immediate brewing.

    Store with care. Heat, light, humidity, and oxygen all accelerate the deterioration of your coffee bean's flavour and aroma by damaging the delicate coffee oils. Store your coffee in a clean, dry, airtight container in a cool dark place.
    • Don't store your coffee in the refrigerator because it may absorb odours from other food products which can affect the taste.
    • It is not recommended to freeze coffee because it can have a damaging effect. Use this practice only if you will not use-up your coffee for a prolonged period of time, two weeks or more. But don't take them in and out very often because the subsequent condensation will affect the beans once they warm.


  • Once the beans are ground, they come into contact with air and begin to react with the oxygen which not only starts to dry the precious oils from the grounds but also begin to shrink in size. As these oils have dissipated so will the flavour of your coffee. The coffee surface area which has now been increased to almost quadruple its original bean size field rapidly losses aroma.


  • Drink instant, freeze-dried coffee at your own risk!
