Michael and Tina Gehrken are the proprietors of the Blackburn Estate in Tanzania, a renowned coffee farm situated on the border of the Ngorongoro Crater. They are recognized for their long-term commitment to high-quality specialty coffee production and their dedication to ecologically sound farming practices, including the preservation of significant wildlife habitats on their estate.
Michael and Tina Gehrken operate the Blackburn Estate, a distinguished coffee farm located in Tanzania. Michael Gehrken, originally from Germany, first traveled to East Africa in 1971 at the age of 19. His connection to the region deepened over the following decade, leading him to relocate to Tanzania permanently in 1983 to take over and renovate his parents' farm, which had fallen into disrepair and was largely overgrown at the time.
The estate is geographically significant, situated along the southern border of the Ngorongoro Crater, a UNESCO World Heritage site. This location places the farm in a unique ecological position, overshadowed by Mount Oldeani, also known as 'Bamboo Mountain,' which reaches an elevation of 3,188 meters. The farm's history is tied to the liberalization of the Tanzanian coffee market in the late 1980s, which provided the opportunity for the Gehrkens to transition the estate into a viable, high-quality coffee operation.
Central to the identity of the Blackburn Estate is the Gehrkens' commitment to environmental stewardship. Recognizing the sensitivity of their location near a major conservation area, they have dedicated approximately 80% of their total land to wildlife preservation. This approach integrates coffee cultivation with the protection of the surrounding ecosystem, a practice that has become a hallmark of their reputation in the specialty coffee industry.
For the specialty coffee drinker and roaster, the Blackburn Estate represents a model of estate-grown coffee that prioritizes both quality and land management. By balancing agricultural output with the maintenance of a wildlife preserve, the Gehrkens have positioned their farm as a notable example of sustainable land use within the Tanzanian coffee sector.
Their work has garnered recognition within the industry, with Blackburn Estate frequently cited as an award-winning producer. The estate's output is often highlighted by roasters who value the specific terroir provided by the Ngorongoro region and the meticulous processing methods employed by the Gehrkens to ensure the quality of their harvest.
Today, the story of Michael and Tina Gehrken serves as a case study in the longevity of family-run estates in East Africa. Their transition from restoring a neglected property to managing a globally recognized, ecologically conscious farm reflects the broader evolution of the specialty coffee market, where the identity of the producer and the environmental impact of the farm are as critical to the final product as the cup profile itself.
