Under the double assault of climate stress and disease, Indonesia's coffee production is declining—can the Komasti resistant variety break through?

In recent years, Indonesia's coffee industry has faced severe challenges under the dual pressures of climate change and farm pests and diseases. The USDA Foreign Agricultural Service predicts that Indonesia's coffee exports will decline by 32% year-on-year in 2023/24. Previously, excessive rainfall disrupted coffee fruit development, leading to a sharp reduction in yield; now, high temperatures and drought are accelerating the spread of pests and diseases, restricting tree growth and further causing coffee supply shortages. Faced with this situation, the Indonesian Coffee and Cocoa Research Institute (ICCRI) continues to seek solutions through agricultural research, including the introduction of the disease-resistant and high-yielding Komasti Arabica variety. In 2022, ICCRI partnered with the World Coffee Research Institute to establish a demonstration plot in West Java to showcase the variety's performance to local farmers. Front Street Coffee is paying attention to this important development in Indonesia's coffee industry, and this article will review the research and development background, current promotion status, and future potential of the Komasti variety.

Ethiopian Coffee Variety Analysis: Characteristic Differences Between the Native Heirloom Variety and the Numerically Bred Varieties 74158, 74112, and 74110

Ethiopia, as coffee's genetic treasure trove, has a variety system far more complex than one might imagine.

What exactly is Ethiopian heirloom native coffee bean? A full analysis of variety naming and flavor origins

Ethiopia is celebrated as the birthplace of Arabica coffee, and its local coffee varieties are as numerous as the stars.

As a result, a broad and romantic term—heirloom—has become synonymous with these native coffee varieties. Heirloom is not a specific variety, but rather a collective term for the large number of coffees in Ethiopia that have not been clearly classified. This article will guide you through the meaning of heirloom, why it is named this way, how local coffees are named, and the brewing and flavor performance of the Yirgacheffe natural red cherry as an example.
