Type of coffee beans:
• American (regular) roast: beans are medium-roasted, resulting in a moderate brew, not too light or too heavy in flavor.
• French roast and dark French roast : heavily-roasted beans, a deep chocolate brown which produce a stronger coffee.
• Italian roast : glossy, brown-black, strongly flavored, used for espresso.
• European roast: two-thirds heavy-roast beans blended with one-third regular-roast.
• Viennese roast: one-third heavy-roast beans blended with two-thirds regular-roast.
• Freeze-dried coffee: brewed coffee that has been frozen into a slush before the water is evaporated, normally more expensive that instants but with a superior flavor.
• Decaffeinated coffee: caffeine is removed from the beans before roasting via the use of a chemical solvent (which disappears completely when the beans are roasted) or the Swiss water process which steams the beans and then scrapes off the caffeine-laden outer layers
