This is a research profile, not an independently conducted farm visit. Producer and coffee relationships are shown only when the records agree. Check the research sources below for supporting evidence.
The story
Blackburn Estate is located in Karatu, Tanzania, near the Ngorongoro Conservation Area. The estate is managed by Michael and Tina Gehrken, who have maintained a long-term relationship with international roasters.
Challenges
The estate faces potential water scarcity, which they mitigate by utilizing spring water from Mount Oldeani stored in reservoirs.
Innovations
The farm operates its own dedicated wet mill and processing facility to maintain quality control.
Published coffees linked to this farm
For blends, a farm may be named for one documented component without growing the entire coffee. These catalog relationships do not independently verify every lot, harvest or producer. See individual coffee profiles for traceability evidence.
