Tanzania Shiviwaka AA Coffee: Growing Environment, History and Brewing Guide

Shiviwaka is a Swahili word that the Tanzania Coffee Farmers Association registered in 2009 as a non-governmental organisation run by farmers themselves. It represents the interests of 8,500 farmers across six different group organisations in the Mbeya, Mbozi, Busokelo, Ileje and Rugwe regions. Shiviwaka smallholders own an average of 1.5 acres of coffee, particularly in Mbeya, where average annual rainfall is about 1,500 millimetres. The association is building strong partnerships with Sucafina to ensure farm sustainability. Tanzania's coffee production is concentrated in five major geographic regions: the north (Kilimanjaro, Arusha and Tary), the west (Kigoma and Kagera), and the south (Mbeya, Songwe, Iringa, Njombe and Ruvuma).

In recent years, coffee from Mbeya has become genuinely noteworthy. Tanzania is famous for its Peaberry coffee, but this AA from the Tanzania Shiviwaka Co-op is one of our best African coffees this year. With a new season and a new roasting profile, we believe this is our exotic espresso that has been used as a filter since early last year. The distinctive aroma notes it gives off are interestingly orange, with some dry spices finishing on a smooth cocoa taste.

Key Details

• Region: Mbeya
• Altitude: 1,560 metres
• Varieties: Kent, Bourbon
• Cooperative/Group: Usongwe AMCOS

Varieties

Farmers in Usongwe mainly grow Arabica varieties planted by their ancestors. Kent and Bourbon are the most common, with Compact introduced more recently.

Kent is considered a natural mutation of Typica, originally discovered in India, and is known to be more resistant to rust (Hemileia vastatrix, or coffee leaf rust) than Typica itself. Typica is the backbone of most specialty coffee worldwide, and the first plantations established in the Americas and Asia belonged to it. Its cup is usually balanced and somewhat complex, with high clarity and enough sweetness to keep you interested even as the coffee cools. Even though I have not had the chance to taste Kent in isolation, I suspect it shares classic Typica's cup characteristics.

Processing: Thoroughly Washed and Sun-Dried on African Beds

The Usongwe name comes from the surrounding area and the nearby Usongwe Valley.

Farmers in Usongwe keep mature, well-maintained trees averaging about 20–35 years old. Ordinarily such trees would lose productivity earlier, but thanks to regular pruning and other agricultural practices they remain productive. The genetic lineage of the varieties also deserves credit.

Bourbon was discovered on the island of Bourbon (east of Madagascar, now called Réunion) after the French brought it there from Yemen. Bourbon is susceptible to all the major diseases and pests, which makes it a harder crop to keep profitable in certain countries and regions. Its cup quality, though, is excellent, with high-quality acidity and a clean, sweet taste that holds up as it cools.

The Tanzania Coffee Research Institute (TACRI) has been very active in developing and distributing varieties resistant to coffee berry disease (CBD) and coffee leaf rust, and because of that resistance, farmers are adopting them more and more. Compact is one such new variety, widely taken up in rural areas for its high resistance to coffee berry disease.

Usongwe producers process their coffee at home. On average, a family's coffee farm is only a 15–30 minute walk from its small processing plant. During harvest, cherries are brought to small pulpers and hand-pulped within 7 hours of picking. The cherries are sorted, placed in fermentation tanks, then fermented in clean water for about three days. On the fourth day the coffee is removed from the tanks and washed of all traces of mucilage (the sticky remnant of fruit around the seeds), then placed again in clean water for an additional 24-hour soak. This soak is said to enhance sweetness and is a common practice, particularly in Kenya.

Flavor Profile

Honey, grape and vanilla, with a creamy mouthfeel and a refined, grape-like acidity. It seems very versatile without obvious or overly complex acidity. Texture and sweetness dominate, and it truly is wonderful.

FrontStreet Coffee Recommended Brewing

• Dripper: Hario V60
• Water Temperature: 90°C
• Grind Size: Small Fuji grind setting 4

Brewing Method: Water-to-coffee ratio of 1:15, using 15 g of coffee. First pour 25 g of water and let it bloom for 25 seconds. Pour to 120 g, then stop. Wait until the water level in the coffee bed falls halfway, then continue pouring slowly to a total of 225 g. Extraction should take around 2:00.

Analysis: A three-stage pour makes the front, middle and back of the cup easy to distinguish. Because the V60 has many ribs and drains quickly, pausing between pours helps extend the extraction time.

FrontStreet Coffee Recommendation

This Tanzania AA is a wonderfully versatile cup — sweet and creamy, but bright enough to drink as filter or as an exotic espresso. If you brew espresso or use a moka pot at home and want the same balance of cocoa depth and soft fruit, FrontStreet Classic Espresso Blend is the go-to. Built on a traditional Mamba recipe, its standout strength is crema: even with a non-professional home machine, beginners can pull a dense, silky shot — exactly what a latte, cappuccino or Dirty needs.

For those chasing a sweeter, lower-cost daily espresso, FrontStreet Dark Cocoa Blend is 100% Arabica, generous with crema and full-bodied, yet gentle on the wallet. If you want a plain, classic Italian-style taste — the espresso flavour most of us remember — FrontStreet Specialty Blend pairs Brazil Cerrado with Colombia Huila and has been the backbone of the FrontStreet bar for nearly a decade, working equally well at home or behind a commercial bar.
