What is the main impact of the three waves in the development of coffee products

What are the three major waves of coffee product development

Another version is that in the mid-13th century there was a Muslim named Sheikh Omar who was suspected of witchcraft and was banished to Mocha, a desert area in Yemen. He had no food or water on him. He happened to see a bird nibbling coffee red fruit. He also went to taste it. It didn't taste very good. It had a bitter taste. So he tried to improve its taste with roasted beans. He collected water to boil the roasted beans. It became our coffee solution. With this coffee alone, he persisted to the place where people smoked. People regarded this as a miracle, calling coffee a "magic potion". The Muslim was invited back to the original mosque and offered as a local holy man (similar to Buddha). Coffee was also discovered as the "holy water" of local Muslims and spread.

In the 15th century, the hand grinder was invented and has since been perfected in many places. Voice-over, a major improvement in barbed wire was achieved through a hand-operated bean grinder.

Freeman is extremely demanding about the origin of coffee beans, and the record of origin is extremely detailed. They stick to beans that are roasted for less than 48 hours, use organic beans, claim "slow coffee" that takes five minutes per cup, and commit to single origin coffee. Only after painstaking roasting can coffee beans fully release the subtle aromas and flavors that can be described by terms such as bean sprouts, dried bananas and licorice. In Freeman's life, his frames of reference are Proust, Mozart, stereo equipment in the early 1970s, and Japanese coffee equipment in the 1920s. The ultimate pursuit of coffee is all about "unnecessary beauty" and willingness to work hard for it. And that seems to be a common trait among the good coffee people in the third wave of coffee.
