India Ratnagiri Thermal-Shock

Ratnagiri Estate sits in Chikmagalur's rolling hills and represents India's specialty coffee frontier under Ashok Patre's direction. Working with two microbiologists, Patre monitors fermentation metrics with precision to craft coffees that defy India's traditional profile—this inaugural lot proves the estate's commitment to balance and cleanliness. The thermal-shock processing method amplifies these qualities, creating a coffee that stands apart from conventional Indian offerings. Worth seeking for its scientific rigor and proof that India's terroir can yield refined, competition-level specialty coffee.
