The Soul of South Indian Coffee
For decades, the morning ritual in many South Indian homes has been the gentle, patient drip of filter coffee, or 'kaapi'. Brewed in a two-chambered steel filter, this method produces a thick, potent liquid called a decoction. The coffee powder itself
is often a specific blend of dark-roasted Arabica and Robusta beans mixed with chicory, a root that adds a characteristic bitter, caramelised depth. This strong decoction is then mixed with hot, frothed milk and traditionally served in a steel 'davara' and tumbler, creating a drink that is both intensely flavourful and comfortingly familiar. It’s a brewing tradition that predates Western-style café culture by generations and remains deeply ingrained in the cultural fabric.
India's Third Wave Coffee Revolution
Parallel to this time-honoured tradition, India is experiencing a 'third wave' coffee movement. Cities like Mumbai, Bengaluru, and Delhi are now dotted with specialty coffee shops where the barista is an artisan and coffee is treated like fine wine. This new culture is driven by a younger, more curious generation of consumers who are interested in single-origin beans, artisanal brewing methods, and authentic experiences. This has created a fertile ground for innovation, with baristas and roasters experimenting with everything from fermentation to new brewing techniques, all while connecting directly with coffee estates in regions like Chikmagalur and Coorg. It’s in this dynamic environment that the old and new are beginning to merge.
The Cold Brew Reinvention
So, how exactly do you turn a hot, milky tradition into a chic cold brew? Baristas are taking the core elements of filter coffee and applying modern cold brew science. Instead of a quick hot water drip, they steep coarse-ground filter coffee powder—chicory and all—in cold, filtered water for an extended period, typically between 12 to 24 hours. This slow, heat-free extraction process creates a smooth, concentrated coffee that is significantly less acidic than its hot-brewed counterpart. The result is a concentrate that captures the unique, earthy, and chocolatey notes of filter coffee but in a completely new form. Some cafes adapt this by chilling the traditionally brewed strong decoction and using it as a base.
The Perfect Drink for a Humid Monsoon
The connection to the monsoon is more than just a marketing gimmick. While a hot kaapi is perfect for a cool, rainy morning, the humid and sticky afternoons of the Indian monsoon call for something more refreshing. This cold brew hybrid offers the best of both worlds. It delivers the cooling refreshment of an iced coffee, but with the familiar, comforting, and robust flavours of traditional filter coffee. There's even a type of Indian coffee bean known as Monsoon Malabar, where beans are exposed to monsoon winds for weeks to develop a unique, low-acid, and earthy flavour profile, making it a natural fit for this seasonal drink. The result is a beverage that feels both invigorating and deeply satisfying on a damp, overcast day.
A Taste of Modern Tradition
The final product is a revelation. It’s smoother and less bitter than a hot filter coffee, yet richer and more complex than a typical cold brew made from single-origin beans. The chicory plays a key role, lending a full-bodied, almost chocolatey character that stands up well to being chilled. It is often served over ice, diluted with cold water or milk (including plant-based options like oat milk), and sometimes sweetened with a touch of jaggery syrup for an even more traditional flavour note. It’s a drink that respects its roots while confidently stepping into the contemporary global coffee scene, proving that tradition can be a powerful ingredient for innovation.
