Under the watchful guidance of sibling team Neel and Kavita Vohora, the Edelweiss and Gaia farms have begun to blossom from well-managed estate farms, spanning 1000 acres across multiple ridges of the Ngorongoro caldera in northern Tanzania, into an innovative and genre-defying coffee enterprise. Our friend Chris at Royal Coffee importers worked with Neel and Kavita and the coffees from the farms for 15+ years. 

Among the family’s favorite cultivar selections are the SL-28s, coffees descended from some of the earliest Arabica selections made in Africa outside of Ethiopia. Tanzania was among the first colonial coffee cultivated on the continent – Bourbon trees from Réunion were delivered to the Bagomoyo mission as early as 1868. From this expanding population of C. arabica var. Bourbon a selection was made in the early 1930s by a now-extinct British agricultural breeder called Scott Labs. SL-28 is Tanzanian stock, chosen for its drought resilience almost 100 years ago, and it found its home primarily in Kenya (where the lab was based) and earned a reputation with growers for bountiful harvests and large screen sizes and with cuppers as a bastion of cup quality. The Vohoras’ SL-28s thrive on the farms as productive trees (if susceptible to diseases like berry fungus) and frequently top the siblings’ cup rankings in their lab. 

The Vohoras’ farms continue to innovate in processing methodology as well. Rather than resting on the laurels of tradition, nearly all of their coffee (including the commercial volumes of larger lots) goes through a cherry maceration period prior to processing. For microlots, like this SL-28, the timeframe for whole cherry “pre-fermentation” is determined specifically by cultivar, through a trial-and-error process that’s been honed into precise protocols to bring out the best in each variety. In this case, the SL-28 harvest will macerate in whole cherry on raised beds under protective tarps for four days prior to completing the nearly 4-week drying process on raised beds in whole cherry. After this is finished, the dried coffee is stored in GrainPro until it can be milled in Vohora’s facility back in Arusha.  

Ngorongoro, the world’s largest unbroken caldera, looms over a verdant landscape, the shell of an ancient, ruptured volcano. Inside its walls, a wildlife conservation area cut off from much access to the outside world, is home to hordes of zebra, eland, gazelles, wildebeests, two prides of lions, hyenas, hippopotami, and scores of other local birds and mammals, including a small population of black rhino. The Maasai, among the region’s more visible residents with distinctive red flannel robes and unchanged traditions of nomadism, are frequent visitors, passing through the crater with their goat and cattle herds in tow. The caldera’s wildlife are no strangers to the farms, either. Native forest corridors on the estates allow freedom of movement for the animals as they migrate, but it’s fairly common to find damage to the coffee trees; the most frequent offenders being elephants and water buffalo.  

The Vohora’s estates are nestled into the caldera’s outer ridges, bordering the park. Since 1971, the Vohoras have owned about 1000 acres of farmland on the southern exterior slopes near the town of Karatu. The siblings’ grandfather arrived from India, first working for the British colonists as a farm manager prior to the nation’s independence, and their father founded and ran the export business from nearby Nairobi. 

Today, Neel manages the farms, including overseeing more than fifty full-time employees and nearly eight hundred seasonal workers during the peak of harvest. He’s also at the forefront of processing innovations and cultivar selections. Kavita helms the export business from Arusha and is the lead cupper and licensed Q-grader at the dry mill. Her daughter, Nicolene, is learning to taste coffee… the family’s fourth generation, now in training.
