„“In humans, tolerance to some subjective effects of caffeine as well as partial tolerance to sleep seems to occur, at least in some individuals” (9). “In humans, the reinforcing stimuli functions of caffeine are limited to low or rather moderate doses that are usually present in a classical serving of coffee or soft drink” (9) and “Caffeine has weak reinforcing properties, but with little or no evidence for upward dose adjustment possible because of the adverse effects of higher doses” (10). These two reviews suggest that caffeine meets some but not enough of the criteria for a diagnosis of dependence.“

„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. Freezing is not necessary to maintain the flavor.“

„Coffee and caffeine have been the subject of extensive scientific research in the last 25 years. Some 1500 to 2000 papers per year have been published and we can assume that there are few products that we consume that have been so thoroughly and deeply studied. New research has shown that caffeine has many positive effects on the body—from improving concentration to fighting depression and reducing the risk of gallstones.“

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.“

„Decaf Espresso? Low-caffeine espresso? That is why we stock the Brazil SWP Decaf as a base. Use it as 50% of your blend to cut the caffeine in half, then add your main "character" coffees as usual.“
