Storing Coffee for Optimal Freshness
For many years my wife and I bought our coffee beans in bulk. We both delight in taking the time to grind and brew our gourmet coffee, but we started to notice that toward the end of the bag the beans started to taste a bit off. That led me to do some research on coffee storage. How should the beans be stored, I wondered – in their raw, green form, or roasted? Left whole or ground? Frozen or at room temperature?
It didn’t take long to discover that fresh roasted coffee beans store best, and they should be kept whole until just before consumption. Most beans will retain their freshness for up to two weeks when stored at room temperature provided that they’re kept in an airtight container. When storing your own beans, bear in mind that they create excess carbon dioxide. Open up the lid of the coffee periodically to allow this gas to disperse.
CAFFEINE: The chief mood altering substance in coffee, with an average of 1.1 percent in Arabica and 2.2 percent in Robusta beans, the tow main coffee species. When extracted, as in the decaffeination process, caffeine is a pure white crystal, bitter to taste. Caffeine is the world’s most widely used psychoactive drug, appearing naurallin in tea leaves and, in very small quantities in cocoa beans.
CAFFEINE WITHDRAWL: Not yet an official diagnosis, but a syndrome currently under research for possible inclusion in psychiatric manuals . its symptoms include headache, sleepiness or drowsiness, impaired concentration, difficulty working, precession, anxiety, irritability, nausea and vomiting, and muscle aches or stiffness.
CAPPUCCINO: A espresso based drink classically made with one third espresso steamed milk and one third foamed milk. The king of Italian espresso drinks.
CARAMELIZATION: Beans are naturally high in carbohydrates, which must be heated to develop toasty, sweat flavours. Caramelized sugars give body and mouth-feel to darker roast: the darker the bean, the higher the degree of caramelization. When caramelization is taken to far, coffee tastes burnt.
CEZEV: More commonly called an ibrik, this is the correct term for the long handled brass or copper pot, tinned on the interior that lopes inward at the top and is used to make Middle Eastern coffee.
CHERRY: Coffee beans are seeds of a berry, called cherry for the shape and for the deep crimson color of the fully ripe fruit. The even, ovoid shape resembles a plump holly berry or cranberry.
