Coffee: Old Familiar Becomes New Favorite (#)
„As for roasting method, darker-roasted beans actually have less caffeine than those that are lighter, because heat from roasting removes the caffeine. Brewing methods that expose coffee grounds to water for longer periods, as in percolated coffee or the "French press" method, result in higher caffeine than standard drip methods. Is this renewed interest in coffee good or bad for our health? The answer probably depends as much on what you consume in the coffee, or with it, as it does on the coffee itself.“

„Researchers say they have genetically engineered coffee plants that have 70 percent less caffeine than usual in their leaves. The crucial question for brewing coffee - whether beans from those plants will have less caffeine - won't be known for three to four years when the plants mature, said study author Shinjiro Ogita.“

Caffeine and The Bean (INeedCoffee.com)
„It is a very effective solvent at the high pressures. When the coffee beans are exposed to the solvent, the caffeine migrates to the solvent. When the removal of caffeine is complete, the now caffeine-rich carbon dioxide is passed through either an activated charcoal bed or a bath of water to absorb the caffeine for re-use. Like other chemical methods, the Supercritical Carbon Dioxide method removes 96 - 98% of the caffeine.“

Matching the right grind to your brewing time
„No matter what coffee beans you use, the right grind for brewing great coffee depends on the brewing cycle of your coffee equipment. Dr. Brew recommends that if you don't know your equipment's brewing cycle, take a watch and time how long it takes for the water to pass through the grounds and fill the decanter.“

„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.“
