Why Fresh Coffee Beans Make Such a Difference?

Coffee beans need to be degassed after roasting. During degassing, the coffee flavour attributes starts to rise, peaking at 1 to 3 weeks after roasting. This explains why coffee beans require some time to settle in order to extract the most prominent flavour. During this period, the taste and aroma of coffee will change moderately. It is always fun to experiment the slight variations in taste and aroma, and find out the best coffee you like within the degassing period.

As far as freshness is concerned, roasted coffee beans begin to age (due to oxidation) the moment we release them from the hot roaster to the cooling tray. After a period of time, when all the desired flavours falls flat, the roasted coffee beans are considered old. When using old roasted beans for coffee, it may taste cellared or oxidised. Since oxidation happens at a much faster rate with ground coffee, grinding roasted coffee beans just before brewing can retain the freshness of the beans for as long as possible.

We advise you to make your coffee 1-3 weeks after roasting for optimal taste and aroma.

To ensure coffee beans remain the freshest and of the highest quality, we strongly recommend that the quantity of coffee you order each time should only cover 2-3 weeks of consumption. Read more on how we handle Order and Delivery
