Whole bean coffee maintains peak flavour for two to three weeks after roasting. During that time, the coffee beans release carbon dioxide gas that drives away oxygen and keeps the beans fresh. Once the coffee stops releasing CO2, the beans start to oxidize and stale. Believe me, you can taste the difference!
What happens once the coffee is ground? Coffee begins to stale about twenty-five minutes after grinding because the increased surface area allows the CO2 to escape much more quickly. That's why we encourage all our customers to grind their own coffee immediately before brewing. If you don't have a grinder, though, or wish to give coffee to someone who may not own a grinder, we're happy to grind the coffee for you. While under 25min is ideal, generally ground coffee if stored correctly with taste good for one to two weeks.
Proper storage: with both whole beans and ground you can maximise the life of your coffee by storing it properly. We recommend and sell Airscape airless storage containers where you can reduce the air around the coffee therefore slowing down how quickly it oxidizes.
