Arabica vs Robusta: What Coorg Grows and Why It Matters

Coorg grows approximately 70% Arabica and 30% Robusta — a ratio that reflects both the region's climate advantage and the market reality that South Indian filter coffee has traditionally blended the two for body and crema.

Arabica (Coffea arabica) is the specialty-coffee world's default. It grows at higher elevations — above 900 metres — where cooler temperatures slow the cherry's development and allow more complex sugars and acids to form. Our estate at 1,200 metres grows primarily S795 (a Kenyan descendant with excellent disease resistance) and SL9. Arabica produces cups with brightness, floral notes, and fruit-forward sweetness — especially at light-to-medium roasts.

Robusta (Coffea canephora) is more forgiving. It tolerates lower elevations and humidity, produces more fruit per tree, and has nearly twice the caffeine of Arabica. That caffeine also makes it more bitter — which, counterintuitively, is exactly what traditional South Indian filter coffee needs. The bitterness of Robusta balances the milk's sweetness and adds the body and crema that the filter method demands.

For pure origin drinking — pour-over, AeroPress, cold brew — we recommend our Arabica lots. For the filter coffee ritual, especially with milk and chicory, a blend of 60–70% Arabica with 30–40% Robusta gives the most satisfying result. Our Coorg Classic Filter Blend is built on exactly this ratio.

If you want to experiment, try our Robusta Dark Roast as an espresso base. You will get a thicker crema and a more intense, low-acid cup than a pure Arabica espresso — which is why most Italian espresso blends historically included some Robusta.
