For many people, drinking coffee is part of their day. Some cannot do without it at breakfast, others prefer it in the form of an espresso after a meal. Due to its frequent use, most households are likely to have coffee in various forms: as beans, ground or processed into pods or capsules. All commercially available forms have one thing in common. The coffee is sealed airtight in them. This prevents moisture from getting into the pack. The type of packaging guarantees a long shelf life. But apart from the best-before date on the coffee, there is also a flavour recommendation as to how long it should be kept. This is because coffee loses its flavour the longer it is stored, tastes rancid and is therefore no longer edible.<\/p><\/blockquote>\n

What is the shelf life of coffee?<\/strong>
\nIn principle, raw coffee beans have an unlimited shelf life. However, few consumers will buy unroasted coffee beans that they process themselves. Instead, they will buy roasted beans or coffee that has already been ground. Due to the processing, these can only be used for a limited period of time. As a rule, the best-before date (BBD) is between 18 and 24 months in the future. If the packaging is unopened, it should not be a problem to use the coffee beyond this date. The information should primarily be understood as a promise as to how long the quality of the coffee is guaranteed.<\/p>\n

However, when a coffee pack is opened, quality deviations become noticeable earlier. This is because two important functions of the flavour protection packaging are no longer available. If it is intact, it maintains the vacuum in the coffee pack. This prevents the flavours from escaping. Secondly, it prevents light from reaching the coffee. Both light and contact with oxygen in the ambient air promote the oxidation of the coffee. As the flavours come from the oils in the coffee beans, this leads to a rancid taste.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

It is best not to buy coffee that comes from a large industrial production facility. Small coffee roasters like ours are an ideal place to go. We can guarantee the freshness of the beans as we roast them especially for our customers. This means that coffee from small manufacturers has a particularly long shelf life. Anyone who buys our roasted beans can expect them to retain their freshness for up to three years. This is also due to the functional packaging used by professional roasters. The beans are not placed in vacuum packaging as they are in the shops. Instead, containers with a one-way breathing valve are used. Coffee beans outgas after roasting. If there is no way for the air to escape, the packaging inflates. At high pressure, this increases the risk of the packaging being damaged. The so-called flavour valve allows the air to escape. At the same time, it prevents the ingress of ambient air, which would impair the quality of the beans.<\/div>\n

What is the best way to store coffee?<\/strong>
\nThere are no special storage recommendations for originally sealed coffee packs. The protective effect is sufficient to ward off the dangers of everyday life. The situation is different if the pack has been opened. A quick reaction is required here. This is because the coffee loses a large part of its flavour within just a few hours, which it releases into the surrounding air. Ground coffee is more susceptible to this than whole coffee beans.<\/p>\n

To preserve the flavour, the coffee should be placed in a container that can be sealed airtight. The seal is also important as coffee can easily take on the odour and taste of other foods. This risk is particularly high if the coffee is stored in the fridge. The storage container should not have a transparent lid so that UV light cannot penetrate inside.<\/p>\n

If you do not have a suitable tin or if your tin does not have enough space for all the coffee, you can also seal the pack with a coffee clip and store it in a dry and cool place. Coffee stored in this way should be used up as quickly as possible. In general, the following storage instructions apply.<\/p>\n
