How long does coffee stay fresh after roasting?

And how to store your coffee at home to maintain its flavour.

As our expertise goes further than just creating a quality blend, we like to share our knowledge to better educate our customers to get the best out of our coffee, so you may be surprised to hear that coffee brewed straight from the roast isn’t always at its best…

After roasting coffee beans need time to settle

After beans have been roasted, once cooled they are packed in our specialist packaging, which locks in the freshness (more on that later). However, post-roast beans need time to settle before going out to sale. This is because fresh off the roast, coffee has high levels of carbon dioxide and nitrogen gasses. In fact, once the coffee has been roasted you have two peak forces that are working in opposition with each other, degassing and oxidation.

Degassing of the carbon dioxide produced happens very aggressively in the first week after roast, which makes the coffee active, due to the rapid rate the gas is being released. Quite often we can hear this process happening due to the gas release valves we have on our coffee packaging – it can be quite amusing but that’s another conversation!

On a more serious tip, coffee that hasn’t had the opportunity to settle will create inconsistencies in flavour. The brews will be lacking in clarity and the depth of flavours will be missing, in fact, the gassier and more unsettled the coffee the more the flavour has been likened to a sharp, metallic tone.

The second force is oxidation. A process which starts as soon as the coffee comes out of the roast. Oxidation is caused by exposure to our oxygen atmosphere and is not just responsible for making coffee stale, of course, oxidation is also what makes metal rust and other foods go off. We tackle this issue again with our specialist packaging (again, more on that below).

There is a debate that settling times can vary depending on the bean variety and origins, however at Dancing Goat Coffee we have found that 4 resting days is the optimum time for our blends.

How whole bean coffee straight off the roast reacts with your machine and grinder.

Coffee that has not had enough time to settle can lead to unpredictable and uneven consistency from extraction to extraction. On the odd occasion that we have used beans that have been too close to roast our family of coffee experts have experienced this issue, which has frustratingly led to difficulty dialling in the grind settings, on a daily basis! This also creates the inconsistency in flavour we mentioned earlier.

“Beans cannot be ground directly after roasting as they are too soft and would be crushed, flattened, and scarred. When the beans are cool, hard, and brittle, they may be ground.” Michael Sivetz’s Coffee Processing Technology, Volume 1

Roast freshness is prolonged by our bespoke packaging

Our packaging is designed to allow the Co2 to be expelled, whilst sealing in the coffee’s freshness, which blocks the oxidation process from taking place. This locks in the flavour and gives the coffee months of shelf life, ensuring your cup is always up to scratch. We store both our beans and ground blends in a cool, dark environment to further prolong the quality of our coffee.

So how do you store your coffee at home to get the best and longevity from the roast?

Whole bean –

Once you have received our coffee, the flavours and freshness have, of course, been locked in with our special packaging. With whole bean, your coffee is fine stored in your grinder, bean to cup machine canister or left in the bag but clipped to lock in the freshness for longer. Of course, if you do not drink a large amount of coffee, we do not recommend you pour your whole bag into your grinder or machine as the longer the exposure to the atmosphere, it will degrade the beans. Only pour the amount you would need for a couple of days at the most to ensure you are getting the best from the flavours and keep the rest of your beans stored in our special packaging and sealed – or even better an airtight container.

Ground –

As ground coffee has a larger surface area the oxidisation process happens at a quicker rate once opened. So, you will need to store your coffee in an airtight container to ensure that the oxidation process does not deplete the quality of your ground coffee. If you don’t have a canister or airtight container an alternative solution is to close the top of the bag with a clip or with a rubber band, then put the bag in a resealable plastic bag, to add an extra layer to lock in that freshness for longer.

Store your coffee away from light, heat and moisture

Perhaps self-explanatory, but always worth noting! Your coffee needs to be kept in a dark place and any other elements that could contaminate the blend which will, of course, have a detrimental effect on the quality of your coffee and speed up the oxidation process.

So, when you hear the term ‘fresh coffee’ you can now be assured this means freshly roasted, packaged, sealed and had the time to settle before being sent out to be enjoyed in your cup!
