Ask Gail: How Long Do Coffee Beans Last?
Coffee! Coffee! Coffee! We love our coffee here and truly drink it up. Our kitchen is always stocked with a 5 pound bag of the good stuff (Yes 5 pounds!) But how long do coffee beans last? Fresh coffee is good coffee. Stale coffee not only has an inferior taste it also can wreak havoc on your espesso timing.
So, we asked Gail to drop some knowledge when it comes to how long coffee beans will stay fresh and how we can make the beans last longer.
Here are some of the big take aways from our conversation:
- Store your beans whole because once you grind them their freshness will begin to diminish in the first 15 minutes. With such a short time frame between fresh and stale when the beans are ground, it's best to grind only the beans you need per brew event.
- Beans from larger roasters (think Lavazza) will have nitrogen flushed their bags. That means before you open the bag, the amount of oxygen in the the bag will be next to none. Oxygen is a key factor in the degradation of coffee bean freshness. So these type of beans will last longer in the unopened bag vs. a local roasted bean (which won't be nitrogen flushed).
- Once a bag is opened it should be stored in cool and dry place. Something like an Airscape is a great place to start.
