FrontStreet Coffee - Introduction to Uganda Coffee Varieties, Processing Methods, and Characteristics

Uganda, located in the Great Lakes region of eastern Africa, lies almost entirely on the East African Plateau. Churchill praised it as the "Pearl of Africa." However, Uganda is far from "dry" - it's quite different from our stereotypical impression of barren Africa. Lake Victoria, the world's second-largest freshwater lake, has 42.8% of its waters within Uganda's territory, and the Nile River also originates here. Although the equator crosses Uganda, the high altitude, crisscrossing rivers, and numerous lakes have earned it the name "Highland Water Country." These unique natural conditions create the foundation for Uganda's coffee cultivation.

Over a hundred years ago, European colonizers introduced coffee cultivation. Uganda's coffee production currently ranks eighth in the world and second in Africa, after Ethiopia. In the past few decades, coffee has risen to become Uganda's most important pillar industry, accounting for 20% of the country's total foreign trade exports. Coffee exports are its main source of foreign exchange earnings. This is a country that lives on coffee - one-fifth of Ugandans, about 8 million people, rely on coffee cultivation for their livelihood. However, most of the coffee grown by Ugandan farmers is Robusta, which is of lower quality and can only be purchased by multinational companies for commercial mass production.

Compared to established production areas like Ethiopia and Kenya, Uganda coffee is more like a rising star on the African continent, but it remains relatively unknown. In the early 1990s, the government abandoned its monopoly and granted export rights to various cooperatives of all sizes, greatly stimulating Uganda's coffee production and quality. The true turning point that captured worldwide attention was the 2017 World Brewers Cup, where Hungarian competitor Michael used a natural-processed Uganda bean to win fourth place. In this competition among masters, all other competitors used Geisha, while using the relatively unknown Uganda coffee to break through and reach the top four can truly be called the dark horse among dark horses. It's worth noting that in coffee competitions held in Panama, a major Geisha-producing region, Geisha and other coffee varieties compete separately; otherwise, it would be like professional teams competing against amateur teams - completely without suspense.

Natural Processing Method

Previously, Uganda only had washed-processed coffee (determined by the natural conditions of abundant rainfall in the country), but natural processing enhances the aroma and sweetness of coffee beans, making fruit flavors more pronounced and flavor layers richer. In today's era of revived natural processed beans, the elegant natural flavors combined with the unique characteristics of coffee origins are what fascinate coffee enthusiasts most.

The basic process of the natural method is: remove floating beans - sun-dry - hull. The natural method is the oldest processing technique. While washed processing remains mainstream, natural processing has seen a revival in recent years. For example, Yirgacheffe has both washed and natural processing methods. This method involves simple procedures and low costs (especially in water-scarce regions), with good body thickness, particularly high sweetness, and mostly possessing mature fruit flavors or even red wine aromas. However, natural processing is highly dependent on weather conditions, requiring long periods of uninterrupted sunny weather, making the drying process and degree difficult to control.

During natural processing, impurities can easily mix in, and because the pulp hasn't been removed, mold can easily develop, resulting in insufficient stability. The natural processed beans in our hands possess flavors produced during the natural drying process - that is, the charming influence of raw beans wrapped in pulp during drying. In the aroma after brewing, this slightly earthy fermented acidity is more pronounced. But such flavors are not defects;恰恰正是 what today's natural processing seeks to achieve - special flavors that fully utilize the fruit aroma and sweetness from the pulp to act on the raw beans, which is also an inevitable result of natural fermentation.

Honey Processing Method

The basic process of the honey method is: remove floating beans - depulp - dry - hull. The honey processing method, also known as semi-washed, was invented by Brazilians and can be considered an upgraded version of the natural method. Since the pulp is removed first, it avoids mold development. Additionally, there's no need to wash the pulp residue from the coffee beans, which also significantly reduces water processing costs. In terms of flavor, because the raw beans are dried while wrapped in mucilage, they absorb the sugars from the mucilage, greatly enhancing the coffee's sweetness and creating richer flavors.

However, honey processing involves complicated steps and higher costs, so finished honey-processed products are not commonly seen on the market. The honey-processed beans in our hands release a rich sweet aroma upon opening the bag, making one doubt whether this is a bag of coffee or dried fruit. The striking fragrance is more impactful than the first two types. Upon tasting, sweetness and fruit complement each other, creating a mellow, sweet fragrance with an endless aftertaste.
