History of Coffee
|November 7 , 2009|
Coffee packaged with a commitment to freshness is easy to spot. Its packaging is specifically designed to protect coffee from the elements that stale it. Coffee is highly perishable and contains more chemical properties (800+) and volatiles than any other beverage. Fresh-roasted coffee not only degrades from exposure to oxygen, light, heat, and moisture—it also releases three times its volume as carbon dioxide gas after leaving the roaster. Although this gas briefly extends the shelf life of whole bean coffee, it also limits proper storage and packaging options.
Whole bean coffee exposed to air and light, as in a glass or a plastic bin, will remain relatively fresh for several days since the escaping gas temporarily serves as insulation. After that time, the beans begin to stale. Unless product turnover is brisk, bin-stored coffee will be stale at the time of purchase more often than not. Coffee sold in a can, a brick package, or other totally airtight container has already staled. Airtight packaging would explode from the pressure of carbon dioxide emitted by just-roasted beans. So, coffee is typically ground and allowed to “degas” for 24 hours, which renders it partially stale prior to packaging. And what about that “burst of aroma” released from a just-opened airtight container? That doesn’t signify freshness. It's simply a coffee’s last gasp of carbon dioxide gas. Since coffee storage and packaging methods frequently compromise freshness, the vast majority of Americans drink stale, bland coffee.
This brings us to the packaging choice guaranteed to offer the freshest product: coffee packaged in a high-barrier one-way (degassing) valve bag. Designed in the late 1960s by an Italian engineer, a one-way valve embedded within the wall of an oxygen-resistant, foil-lined bag permits carbon dioxide gas to escape roasted beans while preventing oxygen from entering. The one-way valve bag is then sealed. Coffee packaged in this manner, and left unopened, will taste virtually identical in freshness to coffee obtained directly from the roaster for nearly three months.
