Storing your coffee
Green beans can last for many years. As with most products, fresh is best, but raw coffee beans have been found in tombs and yielded amazing coffee, apparently. They should not however sweat, so should not be kept in an overly cold place, nor a very hot place. You should also try not to leave them on cold cement floors as they could get too cold, and will draw in the surrounding flavours. The general rule of thumb is that if it's an environment you would be comfortable sitting on, then it’s good enough for your beans too.
Extending the shelf life of roasted coffee relies on maintaining an optimum environment to protect it from exposure to heat, oxygen, and light.
Un-ground roasted coffee beans can be stored in an airtight container at standard room temperature. The ideal spot is in your cupboard. The fridge is not ideal as there is too much risk of moisture, and there is honestly NO proof that it extends the life of your coffee. If you choose to freeze it, then ensure you vacuum pack the lot, and only take them out once. Again, there is no proof that this extends the flavour of coffee so personally we find it an unnecessary process. Alternatively, they can also be kept in resealable zip lock packaging which keeps flavours and freshness for longer. Whole beans can be stored for between 7 – 21 days (depending on the quality of the beans as well as the origin).
Ground coffee deteriorates faster than roasted beans because of the greater surface area exposed to oxygen .Once ground, you can keep your coffee in an airtight container, The coffee is at best 30 minutes after grinding, but can be stored for up to between 7 – 10 days, provided the container isn’t opened daily..
