Just roasted coffee beans need to ‘rest’, to give the flavours of the coffee time to develop. This is because during roasting, coffee beans develop carbon dioxide (CO2) gas. This gas is then released, over time, after roasting. Generally, the resting period required is two to three days (for dark roasted beans) and seven to ten days (for medium and light roasted beans).
Oxygen is the enemy of fresh coffee, as it oxidizes the coffee and makes it go stale more quickly! For this reason, good coffee should always be packed in a foil bag with a one-way valve. One-way valves allow CO2 gas to escape, whilst preventing the ingress of oxygen. This is why we recommend that the coffee of Delish Coffee Roastery is stored by resealing the bag with the strip of tape provided with it. Coupled with this, store your coffee bags in a cool, dark and dry place.
Coffee should not be frozen or refrigerated.
The shelf-life of coffee is a complex subject that cannot be defined exactly, as coffee beans are dry and therefore do not go off (coffee is classed as a non-perishable food item). But suffice it to say that (following the initial ‘resting’ period) the general rule for coffee is ‘the fresher the better’. This is why we at Delish Coffee Roastery always roast our beans to order, i.e. we do not keep stock of any of our products.
So, to make this all practical and for optimum enjoyment, ideally consume our coffee within 4 to 8 weeks after having received it from us. All of our coffees contain a batch number on its packaging, reflecting a roast number, the month and year in which it was roasted, as well as a Best Before date.
