Coffee was the luxury that became a necessity, around the world. One pound of ground espresso beans will yield approximately 50 single shot servings, while the same amount of ground commercial coffee beans yield roughly 45 eight-ounce servings. Coffee Storage Air is a coffee bean's worst enemy. Store ground or whole beans in an airtight container in a cool, dark place, but not in the refrigerator. Do not store next to onions, garlic, or strongly aromatic foods.
Coffee can absorb odors.
Freezing protects flavor integrity, so you may freeze excess beans over longer periods of time. There is no need to thaw before grinding. The fresher the grind, the more flavorful and aromatic the brew. Ground coffee loses its integrity rapidly, so grind only the beans you need.
