The Golden Cup extraction is a widely circulated concept in the coffee world, defining an extraction range that most people find acceptable. This concept originated from a large-scale preference survey in the United States in the 20th century, promoted by the Brewing Committee established by the American Coffee Association in collaboration with Dr. Lockhart of the Massachusetts Institute of Technology. The survey found that about 30% of coffee beans are soluble substances, while the remaining 70% are insoluble fibers.
