When it comes to coffee consumption, espresso coffee culture began to become mainstream around the world, and Italian coffee culture became the basis of global coffee culture. However, coffee makers' efforts to coffee quality and consumers' needs have recently raised interest in specialty coffee, which leads to the latest trend of coffee culture when you go to Portland, Oregon, and Seattle, Washington. A new trend in the global coffee market is Specialty Coffee, which is called the third wave of coffee. COE, which evaluates coffee quality in the U.S. Specialty Coffee Association or production, defines specialty coffee by applying each evaluation method, while Stumptown, the representative of specialty coffee established in Portland in 1999, defines "vivid coffee for both coffee makers and end consumers." In addition to Stumptown, more than 10 coffee brands, including Blue Bottle, Counterculture Coffee, and Intelligensia, which lead the US specialty coffee industry, are consistently striving for the sustainable growth of the coffee industry by focusing on the specialty coffee industry.
