Yes, you read the title right! We are talking about making wine from tomatoes. Tomatoes have always been a kitchen staple, but in a bottle, they’re rewriting the rules of indulgence. India ranks as the second-largest tomato producer globally, yet it struggles with significant levels of wastage. According to the Food and Agriculture Organization (FAO) report, about 30-40% of tomatoes are discarded due to various reasons, such as over-production, poor management, and market fluctuations. Price volatility is another major issue, as supply disruptions and weather events can cause prices to rise.
To tackle the extreme fluctuations in retail tomato prices, the government has selected and funded 28 innovative solutions, including tomato wine production, through a hackathon aimed at enhancing supply chains and processing capabilities. These startups will now receive support to scale up their operations.
On Friday, November 22, 2024, Consumer Affairs Secretary Nidhi Khare announced that the Tomato Grand Challenge (TGC) hackathon, launched in June of the previous year, aims to gather innovative solutions across the tomato value chain. The goal is to ensure tomatoes are available to consumers at affordable prices while helping farmers receive fair value for their produce.
A growing challenge of tomato waste
Tomato processing industries produce substantial by-products such as peels and seeds, which constitute approximately 5-10% of the total weight of tomatoes. These by-products, which are often discarded as waste, contribute to environmental pollution. The decomposition of tomato residues releases greenhouse gases like methane and carbon dioxide, which further increases the problem of climate change.
The Tomato Grand Challenge was launched to address critical issues in India's tomato supply chain. Seasonal fluctuations in tomato prices create significant challenges for both growers and consumers. Prices generally fall between December and March due to the large harvest, but prices may rise from July to November if production is low. This instability often leads to market saturation, causing farmers to suffer significant losses.
A study on the tomato supply chain in Madhya Pradesh, a key tomato-producing state, reveals that approximately 15% of tomatoes are lost or wasted at the farm level, while another 12% are discarded at the retail level.
Tomato wine as a sustainable solution
So, why has tomato wine gained attention in recent years? Tomato wine represents a creative solution to food waste, using excess or ugly tomatoes that might otherwise go unused. The idea of making wine from tomatoes is not only a creative innovation but also a sustainable approach to tackling the twin problems of food wastage and price volatility. Being a highly perishable crop, tomatoes often face supply chain challenges, leading to significant post-harvest losses and wide fluctuations in market prices. The production of tomato wine offers a promising solution.
Instead of throwing away such tomatoes, they can be fermented to make value-added products. This process reduces agricultural waste, reduces environmental pollution from rotting produce, and ensures that a larger portion of the crop can be used effectively. By extending the shelf life of tomatoes through fermentation, farmers and growers can maintain income stability and access alternative markets. Tomato wine fits well with circular economy ideas by reducing waste. The skins and seeds left after winemaking can be used for bioenergy or animal feed.
Another innovative approach is the development of a large-scale water-resistant coating for food delivery packaging, made from biopolymers derived from tomato waste. This eco-friendly alternative offers a sustainable solution to the plastic materials currently used in packaging.
The Science Behind Tomato Wine
Tomato wine is produced by fermenting fruit sugars in the same way as regular wine. Choosing a tomato variety that maintains a balance between sweetness and acidity is important. After harvest the tomatoes are crushed and juiced, and some winemakers choose to add a small amount of sugar to speed up the fermentation process. Yeast is added to the mixture to convert sugars into alcohol through fermentation. This fermentation process usually spans a few weeks, after which the beverage is aged for several months to enhance its flavor.
Tomatoes, despite their delicious reputation, contain high levels of natural sugars and acids, making them perfect for fermentation. The resulting wine can have a surprising range of flavors, from tart and fruity to slightly herbal. Depending on the technique used, it can take on a subtle umami character, reminiscent of the rich, savory profile of a tomato, or even the sweet, sour flavor of a tomato.
What Does Tomato Wine Taste Like?
Tomato wine offers a unique and diverse range of flavors, making it as flexible as it is unexpected. Its taste profile often surprises first-timers, combining a subtle sweetness with hints of tanginess and umami, flavors that are unique to tomatoes. Tomato wine's flavor can vary widely depending on the tomato variety, fermentation method, and added ingredients like garlic, basil, or chili, creating a unique and layered taste.
The role of government in driving change
Through various programs, governments around the world are addressing food waste, especially with regard to perishable items such as tomatoes. In India, the Ministry of Food Processing Industries (MoFPI) promotes schemes like the Pradhan Mantri Kisan Sampada Yojana (PMKSY) to support food processing units that convert surplus crops into value-added products such as tomato paste, juices, and wine.
Research institutes like ICAR are also developing new technologies for long shelf-life and sustainable production, including tomato wine. Similarly, countries such as Italy and the United States are supporting sustainable agriculture and promoting public-private partnerships to reduce waste through innovative food technologies.
The rise of tomato wine showcases how innovation can help solve global issues like food waste. Government support for research, food processing incentives, and resources for farmers are key to this change. By turning surplus tomatoes into wine, we reduce waste and create a new market that benefits farmers, consumers, and the environment.
