After the outer pulp is removed, coffee seeds are prepared by roasting, which develops the aroma and flavor of their essential oils. Longer roasting produces darker, stronger coffee. The variety of recipes and prescriptions for roasting, brewing, and serving coffee reflects the diversity of consumer tastes and cultural preferences. All techniques begin with properly roasted, freshly ground coffee; freshly boiling water; and absolutely clean utensils. Turkish coffee, a strong, unfiltered brew of finely powdered coffee and sugar, is popular in Greece, Turkey, and Arabia. Italian-style espresso, or expresso, is brewed by forcing hot water under pressure through finely powdered, often darkly roasted coffee. Most other coffees are filtered. Café au lait, coffee mixed with scalded milk, is a traditional French breakfast drink, as is café con leche in countries where Spanish is spoken. Coffee flavored with chicory is a specialty of New Orleans. Connoisseurs pay dearly for Mocha from the Yemen region of Arabia, Blue Mountain from Jamaica, Kona from Hawaii, or other so-called specialty coffees from Africa, Indonesia, or Latin America—all premium arabica varieties.
