„* For great taste with less cafeine buy arabica coffee. It's slightly more expensive, but contains less caffeine than blends that combine arabica and robusta beans. * Roasted coffee beans start to lose some of their flavor within two weeks. Ground coffee begins to lose its flavor in minutes.“

„If roasting is too short, the oils won't be brought to the surface and the coffee will have a nutty flavor and lack consistency. Dark roasted beans contain less acid, have slightly less caffeine than lighter roasted beans and have a shorter shelf life, due to the amount of oils on the surface. In darker roasts, it is the roast's smoky, pungent, burnt taste that dominates overtaking the bean's natural flavor. Many times the dark roast's burnt taste will mask beans that are low in flavor and quality.“

Drinking Decaffeinated Coffees
„One method for chemically removing the caffeine from green, unroasted beans involves the following steps. First the beans are warmed by water or steam, which opens up the pores in the bean. Then the beans are rinsed in a solution of methylene chloride which extracts the caffeine without removing the flavor enhancers.“
