If you're seriously about your coffee, then you'll know how important it is to receive it freshly roasted. Because we roast in small batches, the majority of our bags of coffee will have a roast date of 1-2 weeks prior to the day of dispatch. Sometimes, depending on the time of year and other factors, the roast date might be up to 4 week prior to dispatch.
Why does the roast date matter?
A date that tells you when your coffee was roasted is really important because it gives you an idea of how fresh that coffee is.
If you can't see a roast date, or perhaps you can only see an expiry date on a bag of coffee, chances are that coffee is really old and possibly already stale. If your coffee is stale, it won't extract nicely and you won't get a nice crema from it.
The optimum time to use your beans from roast date
Opinions on this differ. Some coffee purists say the fresher the better. We actually disagree and think that freshly roasted coffee should be left to 'degas'. What's degassing I hear you ask?
Degassing is the release of gases from roasted coffee. When you roast coffee, gases – including a lot of carbon dioxide – form inside the bean.
A lot of these gases are released in the first few days after roasting. The problem is that the escaping gases can result in small bubbles when you brew your coffee. These air pockets can get in the way of the coffee grounds and the water, leading to an uneven extraction. So, if you brew coffee that has just been roasted, it can really alter the flavour of your coffee.
That's why we feel it's better to wait a few days after roasting before brewing your coffee.
Remember, good storage is really important if you want to keep your beans fresher for longer. It's worth investing in a good quality airtight container to prevent your coffee going stale too fast. In fact, there's virtually no detectable deterioration in taste over a period of up to around 4-6 weeks, when kept in an airtight container.
