Tanzania Mbeya Region: Flavor and Brewing Reference for Sungura Washing Station's Washed Red Bourbon

Tanzanian coffee carries the hallmarks of Central and East African washed beans: bright acidity and intense flavor. Everyone knows that Kenya still produces superb coffee, but Tanzania is catching up fast and shares many of Kenya's best qualities. This is Gardelli's second year buying coffee from the Sungura Mbozi Coffee Processing Unit, and the quality has been remarkably consistent—bright and full of sweetness.

The Sungura washing station sits in the southern highlands around Mbeya, in western Tanzania. Farmer Business Groups (FBGs) such as Masangula, Isende, and Iyula are cooperative in nature, bringing together smallholders who pool resources, processing facilities, and marketing. In places like Tanzania each smallholder may produce only a few bags of coffee—a very small amount. FBG members therefore combine their micro-lots into a single batch, so the coffee can be processed with larger machinery instead of being handled by hand for lack of volume. The Sungura washing station stands at about 1,750 meters above sea level, while coffee trees can be planted as high as 1,800 meters; the main variety is Red Bourbon.

The Washed Processing Method

The essence of the washed method lies entirely in the bean itself. Washed coffee lets you taste the coffee's inherent qualities rather than outside influences. Washing has to ensure that, during growth, the bean fully absorbs its natural internal sugars and nutrients—which means every step matters: variety, soil, fruit maturity, fermentation, washing, and drying.

Washed coffee reflects the craft of growing perfect beans, and it proves that farmers are indispensable in creating good flavor. At the same time, when we look at washed beans, the producing country and its environment play a decisive role in how the flavor is expressed.

In washed processing, the skin and pulp are removed mechanically, and the mucilage still clinging to the parchment must be removed as well before drying. During processing, the sugars in the mucilage are cleared either through natural fermentation or with machinery such as demucilagers. After a further wash removes all mucilage from the parchment, the beans are spread on drying patios or raised African beds to dry.

FrontStreet Coffee's Recommended Brewing Method

Dripper: Hario V60

Water temperature: 90°C

Grind size: Fuji grinder setting 3.5

Brewing method: Water-to-coffee ratio 1:15, 15 g of coffee. First pour 25 g of water for a 25-second bloom; second pour to 120 g and stop; wait until the water level drops to halfway, then continue slowly until the total reaches 225 g. Extraction time around 2:00.

Analysis

A three-stage pour clearly defines the front, middle, and back of the cup. Because the V60 has many ribs and drains quickly, pausing the pour extends the extraction time.

FrontStreet Coffee Recommendation

This Tanzanian lot is a textbook Central and East African washed coffee, and if that bright, tea-like style appeals to you, FrontStreet Coffee has several washed coffees worth trying. The FrontStreet Kenya Small Tomato is a prime example of double-washed processing, with layered notes of cherry tomato, smoked plum, snow pear, black plum, and yellow sugar over a juicy, sweet-tart body. For a floral, citrus-driven cup, the FrontStreet Yirgacheffe Gudingding Cooperative is washed and medium-light roasted, showing jasmine and bright citrus with green tea and honey on the finish.

Both are well suited to the V60 method above, where the pause between pours helps draw out the clarity and sweetness these washed beans are known for.
