The coffee

This lot comes from Ratnagiri Estate’s Line Patte block, where SLN 9 is given a more experimental treatment through fermentation and drying.

The cherries spend 48 hours fermenting whole with an inoculated LAB microbial culture before moving into a dark room for 14 days of drying.

That combination shifts the cup away from a straightforward natural profile and into something more layered: bright red fruit at the front, with a deeper, vinous quality unfolding through the finish.

The producers

Ratnagiri Estate is led by Ashok and Divya Patre, whose work pairs generations of coffee cultivation with a considered approach to fermentation, drying and lot separation.

Across the estate, different varieties and processing methods are explored independently, allowing each lot to offer its own interpretation of the same place.

Roasting

Roasted for filter to keep the cup bright and defined, allowing the fruit to remain vivid while the fermentation contributes depth without overwhelming the cup.

Brewing

Recommended for filter.
