Scientists in Germany conducted a study, the results of which showed that in the future, the world may form a "coffee" crisis. It will be caused by global warming. It will lead to the fact that the land suitable for growing high – quality coffee-Specialty coffee-will disappear on the planet. In particular, scientists believe that Ethiopia, on the territory of which the world's most popular Yirgacheffe coffee is grown, may lose 40% of the land suitable for this purpose. At the same time, the area of agricultural land that can only be used for growing medium-quality coffee will increase.
Scientists in the course of the study studied the degree of influence of almost 20 climatic factors that affect the quality of five varieties of coffee in the Specialty coffee category. If the climate becomes warmer, the berry pulp will ripen faster than the coffee grain. This will lead to a significant deterioration in the quality of coffee beans. Scientists also noted that in the event of a warming climate, it will be especially difficult for small farms that grow coffee.
