Consolidated profit before exceptional items and tax for the July-Sept quarter stood at 820.4 million rupees ($9.86 million), compared with 503.8 million rupees a year earlier, the company said.
The company, which is a supplier to a joint venture between U.S. coffee chain Starbucks and parent Tata Consumer Products, reported a 51.5% rise in pre-tax profit of its value-added business.
The business accounted for 82% of Tata Coffee's pre-tax profit in the latest quarter.
However, total revenue from operations fell 3.1% to 6.96 billion rupees.
"Coffee Plantation performance was subdued due to lower volumes sold, though realizations have improved," Managing Director Chacko Thomas said in a statement.
Expenses fell 5.3% to 6.37 billion rupees, as raw material costs eased.
Separately, Tata Coffee renamed K Venkataramanan as chief financial officer.
Tata Consumer Products will report earnings next week.
Earlier in the day, consumer major Nestle India beat estimates with a 37.3% rise in September-quarter profit on higher demand for its chocolates and instant noodles.
