12 Traditional Indian Summer Drinks to Beat the Heat

4. Chaas (Spiced Buttermilk)

Chaas, or spiced buttermilk, is a yogurt-and-water drink that’s light, hydrating, and gentle on digestion. Start with plain yogurt whisked with two to three parts water until smooth, then season with roasted cumin powder, salt, a pinch of hing (asafoetida) if you have it, finely chopped cilantro, and thinly sliced green chili for a touch of heat. A blender gives a frothy texture quickly, and a long stir with a wooden spoon is the traditional method favored by many grandmothers. Chaas is thinner than lassi and is designed for regular, everyday drinking especially with meals. Because chaas contains live cultures when made from fresh yogurt, it provides probiotic benefits that support gut health and aid digestion after spicy or rich food. It’s also very low in sugar compared with commercial sports drinks, so it’s a good option for steady rehydration. In regions, you’ll find subtle differences—some add grated cucumber for extra coolness while others keep spices minimal. For a dairy-free twist, try unsweetened plant-based yogurt thinned with water and a dash of salt.
