1990, the earliest ear-hanging coffee was invented by shinya yamanaka Industrial Co., Ltd., and a patent application was formally filed in the same year, but the ear-hanging at that time was unilateral. In 1996, Daejeon Company proposed an improved filter bag, in which the lug part was moved to the lower edge of the filter bag, but the lug part was still only on one side of the filter bag.
1999, Daji Company applied to the European Patent Office for an invention patent for double-sided ear-hanging parts. This improved design can finally make the filter bag stand firmly at the mouth of the cup, and the opening of the filter bag can be completely opened. This design concept has also become the mainstream of today's market.
In 200 1 year, the Japanese invented the ear-hanging coffee and registered the patent, and then put it on the market. Because the operation is simple and portable, the brewed coffee tastes much more pure and fragrant than instant coffee. Today, the coffee with hanging ears has occupied 65,438+05% market share of ordinary coffee in Japan.
Matters needing attention in purchasing fine hanging ear coffee
The origin of coffee beans
The quality of high-quality coffee first depends on the origin of coffee beans, and high-quality coffee beans need to be selected from the origin to ensure the maturity and quality of coffee beans. The taste and flavor of coffee beans from different origins will be different, so you should choose coffee beans from different origins according to your own tastes and preferences.
Baking time
Roasting time is an important factor to determine the flavor and taste of coffee. Excessive roasting will make the umami taste and flavor of coffee beans lose and produce bitterness. However, insufficient roasting will make coffee beans too bitter and sour. Therefore, it is necessary to choose high-quality hanging-ear coffee, and the baking time is moderate to ensure the umami and flavor of coffee.
