Frinsa Estate 2025/26, Indonesia

Full & rich, lemongrass, black tea

roasting notes

Wildan’s coffees have long challenged expectations of Indonesian cup profiles, with a processing approach that continues to push beyond convention.

During the roast, we extend development after the initial soak phase, encouraging prolonged caramelisation to maximise sweetness while preserving vibrancy and subtle red fruit notes in the cup. The result is a layered coffee, with notes of cooked rhubarb and black tea on the finish, delivering a balanced and expressive brewing experience.

Frinsa Estate's 2025/26 lot represents a washed-process expression of the Ateng Super varietal from Weninggalih, West Java, grown at 1400 masl by producers Wildan Mustofa and Atieq Mustikaningtyas. Rosetta Roastery has developed this coffee to emphasize aromatic herbality alongside darker stone fruit and tea-like character—lemongrass and black tea notes paired with cooked rhubarb and red fruit. The cup presents as full-bodied and rich, suggesting the concentrated sweetness and structure typical of carefully managed Indonesian washed coffees. This lot offers an opportunity to explore how the Ateng Super varietal expresses itself through controlled fermentation and processing in its origin terroir.
