Robusta Coffee
Coffea robusta
The estate's primary crop — feedstock for CTA's green coffee, chlorogenic acid and natural caffeine programme.
CTA's backward-integration model links its extraction business to estate cultivation and a farmer buy-back programme — for genuine farm-to-extract traceability.
Most herbal-extract manufacturers buy their botanicals on the open market. CTA is different: through its sister company, Rawther Plantations Merchant P Ltd, the group owns and operates an estate where Robusta coffee is the primary crop, alongside pepper, garcinia and other botanicals.
That estate is the anchor of a wider backward-integration model — a buy-back programme that extends the same approach to partner farmers, giving them assured offtake while giving CTA a traceable, quality-controlled raw-material supply.
From estate cultivation to a widening farmer buy-back network, CTA sources the botanicals behind its extract and speciality programmes.
