Chaas, more popularly known as buttermilk, is a traditional Indian beverage that has stood the test of time and continues to be a favorite in countless households. This cooling drink is prepared with a base of yogurt, water, and aromatic spices, creating a refreshing, light, and digestive beverage that perfectly complements Indian cuisine. Its origins can be traced back to the western states of Gujarat and Rajasthan, where chaas was consumed daily, especially during the scorching summers.
Farmers and workers would drink it after long hours under the sun to replenish lost fluids and soothe their bodies from the heat. Over time, chaas spread across the country and has now become one of the most cherished drinks in India, enjoyed by people of all ages and communities. The cultural significance of chaas is deep-rooted in Indian traditions. In many households, no lunch or dinner is complete without a glass of chaas on the side.
In fact, in Gujarati thalis, chaas is almost mandatory, served in tall glasses that provide instant comfort and balance to the spiced dishes on the plate. South India too has its version called “neer moru,” which is infused with curry leaves, ginger, and green chilies, making it equally flavorful and soothing. These regional variations highlight how chaas has traveled across the subcontinent, adapting to local tastes yet maintaining its essential character as a light, tangy, and refreshing drink. It is not just a beverage; it represents a tradition of simplicity, health, and natural cooling that has been passed down through generations.
Chaas also enjoys a unique place in the world of Indian hospitality. When guests arrive in the summer months, it is often the first drink offered to them as a gesture of warmth and care. In rural India, it is still served in clay cups, which add an earthy aroma and keep the drink naturally cool. In urban restaurants and modern kitchens, it might be presented in tall chilled glasses with mint leaves and ice cubes, yet its essence remains the same. Unlike carbonated drinks or sugary beverages, chaas brings with it both tradition and health, making it a timeless choice for quenching thirst.
What makes chaas special is its versatility. It can be kept plain and simple with just yogurt, water, and a pinch of salt, or it can be elevated into masala chaas with roasted cumin, ginger, and herbs. Some people even prefer sweet chaas by adding a hint of sugar and cardamom, making it an entirely different experience. In Ayurveda, this dish considered one of the best digestive drinks, often recommended after meals to balance the stomach. This adaptability and health benefit have helped this drink remain relevant even today, as health-conscious people around the world seek natural and probiotic-rich drinks to replace fizzy sodas and artificial juices.
The global wellness trend has also contributed to the rising popularity of this drink outside India. Yogurt-based drinks are already loved worldwide, from Greek tzatziki to Middle Eastern ayran, and chaas finds its place alongside them as India’s own contribution. With more awareness about gut health and the importance of probiotics, chaas is being recognized internationally as a super drink. Whether in fitness communities or fine-dining restaurants that experiment with Indian fusion, chaas is steadily gaining recognition beyond the borders of India.

Health Benefits
Chaas is much more than just a summer cooler; it is a drink packed with nutritional and health benefits. Yogurt, the main ingredient, is rich in probiotics that improve gut health, boost immunity, and aid digestion. The addition of cumin helps relieve bloating, acidity, and indigestion. Its low-calorie content makes it a perfect choice for those watching their weight, while its high water content ensures hydration during hot weather. Chaas also provides essential nutrients like calcium, potassium, and vitamins that support bone strength and overall wellness. Unlike aerated drinks, chaas does not burden the body with excess sugar, making it a guilt-free beverage that can be consumed daily.
Kitchen Tip: For a traditional touch, churn chaas using a wooden hand whisk (mathani) instead of a blender—it gives an authentic frothy texture and enhances the flavor.
