Ratnagiri Estate
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
Ratnagiri Estate was founded in 1927 when the grandfather of current owner Ashok Patre purchased the land from British officials. The farm has remained in the Patre family for generations, with Ashok taking ownership in 1989 and transitioning the estate toward specialty coffee production.
Challenges
The farm operates in a complex ecosystem where it must balance agricultural productivity with environmental conservation, maintaining specific shade levels to protect soil moisture and biodiversity.
Innovations
The estate utilizes scientific processing techniques including yeast inoculation, anaerobic fermentation, and rigorous pre-processing cherry sorting based on Brix content analysis. Ashok Patre collaborates with microbiologists to track fermentation metrics to ensure consistency and quality.
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.
