What are the disadvantages of ground coffee?
ground coffee has less flavor and freshness grinding whole coffee beans starts the oxidation process, and once this has begun, there’s no way to stop it. Though packaging methods are designed to considerably slow the degradation process, ground coffee still inevitably loses some of its flavor and freshness in time. In fact, unopened bags of coffee beans can stay fresh for up to a year from the roast date. Once you open a bag of coffee beans, it’s best to consume them within three weeks.The Rule goes like this: Green coffee lasts about 15 months before it goes stale. Roasted coffee lasts about 15 days before it goes stale. Ground coffee lasts about 15 minutes before it goes stale.
