Sula Vineyards charts path to 100% sustainable winemaking amid climate pressures

Climate change is affecting nearly every region in the world. Nashik, known as the wine capital of India, is also feeling the heat. In the last 15 years, almost 50 seasons have been affected by climate change, according to Anil Ghanwat, President, Shetkari Sanghatana, a Maharashtra-based farmers’ union. “Sometimes there are heavy rains, sometimes there is a drought, sometimes the temperature drops below zero degrees in some areas,” he said.

Excessive heat is resulting in overripe grapes and unbalanced wines, while increased temperature raises the risk of fungal diseases in grapevines. “This calls for active efforts needed to be taken by farmers,” he emphasised.

Sula Vineyards, a major winery in Nashik, is working on mitigating the impacts of climate change on its grape farms. Given the frequent droughts and water scarcity in the region, CEO Rajeev Samant said that they are focusing on water management. Sula has employed advanced water recycling, considering India’s monsoon-dependent climate, and it aims to reduce water usage per bottle produced.


Not just water management, Sula is also working on energy conservation. “The methane that is captured during the treatment of wastewater is transformed into clean electricity. This reduces the reliance on natural resources that are subject to fluctuations and enhances the climate resilience of the operation as a whole,” Samant said.

Sula works with over 2,800 acres of contracted vineyards and has processed more than 11,000 tonnes of grapes in FY25. According to the company, it is committed to achieving net zero emissions by 2050.

Samant claimed that Sula Vineyards has incorporated sustainability into every aspect of winemaking.

In FY25, Sula relied on solar power for 65% of its energy needs; this number, as per Samant, is likely to increase to 75% in FY26. Power-saving initiatives, such as the Burkert temperature control system, have already resulted in a saving of 37% of power in the cellar, and further growth is anticipated, he said.

According to him, Sula consumed 5% less water per case in FY25. The company aims to bring it down by 6% in FY26, as it looks to utilise 20% recycled water, he said.

“We have also installed a methane capture facility that generated 35,000 power units in FY25 and aims to increase by 44% in FY26. We also have a localised glass bottle supply chain, which reduces its carbon footprint and supports local economies. The company increased its use of rewash bottles by 24% in FY25 and aims to do so to an even greater extent,” he said.

Low-alcohol wines
The wine manufacturer has also dabbled in low-alcohol wines, which offer a sustainable and healthier alternative to health-conscious consumers and have considerably less environmental impact. Sula’s Source Moscato and Chenin Blanc Reserve are known for lighter, refreshing profiles.

“There is a shift towards light, approachable wines that seem to be gaining traction. Moving towards lower-alcohol wines can be good for consumers, especially from a health and wellness standpoint, as well as from an environmental sustainability perspective. These wines need fewer resources to be put into fermentation and greatly more freedom regarding harvesting and ripening of the grapes,” he said.

However, he highlighted the challenges of sustaining these green efforts due to the high upfront costs of technologies like solar panels, methane capture systems, and EV fleet conversion. “Scaling these efforts while maintaining cost-efficiency and consistent product quality can also be complex,” he said. “Moreover, as climate change intensifies, managing grape quality and yield sustainably remains a long-term challenge,” he added.

Nevertheless, Sula maintains an optimistic outlook for the future. In FY26 and the following years, the company aims to reduce power consumption per case sold by an additional 11%, increase its EV fleet share from 45% to 55%, achieve a 6% reduction in water usage per case while enhancing water recycling to 20%, and realise a 44% increase in electricity generation from methane capture.

“These actions will aid Sula in becoming a pioneer in sustainable innovation while also assisting in meeting the set target of achieving carbon net-zero by 2050,” he said.
