Freshness is one of the biggest factors in how good your coffee tastes, and also one of the most misunderstood parts of the whole process. So we've pulled together the questions we get asked most often about fresh coffee, from how long it actually lasts to whether the fridge is friend or foe, and answered them properly.
As a rough guide, whole bean coffee stays at its best for 2-4 weeks after roasting, provided it's stored properly. After that, it doesn't suddenly become undrinkable, but the flavour starts to fade. The natural oils that carry all that aroma and taste begin to break down, and the CO2 that beans release after roasting (which helps protect them from oxygen) starts to run out.
Ground coffee stays fresh for roughly 30 minutes to a few hours in terms of peak aroma, and about 1-2 weeks before it noticeably starts to lose flavour and go stale.
Why such a dramatic drop from whole beans? Grinding massively increases the surface area of the coffee that's exposed to oxygen. Whole beans protect most of their flavour compounds inside; ground coffee exposes almost all of them at once.
If you're using a cafetière, filter, or espresso machine, buying whole beans and grinding fresh each time will make a bigger difference to your cup than almost any other change you could make.
Here's something that surprises a lot of people: coffee that's too fresh isn't actually ideal for brewing.
Straight after roasting, beans are full of CO2 and other volatile gasses, which are natural by-products of the roasting process. These gases needs time to escape, known as "resting" or "degassing." Most coffees hit their sweet spot somewhere between 5 and 14 days after roasting, once enough CO2 has released for the flavours underneath to come through properly.
This is exactly why we put a roast date on all of our bags rather than just shipping it out the same day.
Coffee is incredibly good at absorbing moisture and odours from its surroundings, which makes the fridge one of the worst places to store it. Every time you open the fridge door, your beans are exposed to condensation and whatever else is in there. That moisture speeds up staleness rather than slowing it down.
