Chhaachh (gu:છાશ)(hi:छाछ) is a dahi (yogurt)-based drink popular across Indian subcontinent.[1] It is also written "chaas;" in Bangladesh and West Bengal it is called "ghol". It is often called "laban" in the Old Dhaka in Bangladesh. In Indian English, it is often called "buttermilk".

Preparation and variations[edit]

Chhaachh is made by churning yogurt (curds/dahi) and cold water together in a pot, using a hand-held instrument called madhani (whipper). This can be consumed plain or seasoned with a variety of spices. Chhaachh can be made from fresh yogurt, and the natural flavour of such Chhaachh is mildly sweet. This type of Chhaachh is very close to lassi, with two major differences: Chhaachh is more dilute (with water) than lassi and unlike lassi, Chhaachh does not have added sugar.

Although Chhaachh can be made from fresh yogurt (curds/dahi), it is more commonly made at home from yogurt that is a few days old and has become sour due to age. Indeed, one of the purposes for making Chhaachh at home is to usefully finish off old yogurt that is lying in the fridge for long. Such Chhaachh has a tangy, slightly sour taste which is considered delicious. A pinch of salt is usually added to it for further enhancement of taste, and other seasonings can be added also, as described below.

A third variation of Chhaachh is obtained by adding actual buttermilk (water left over after churning butter) into the Chhaachh. This gives a slightly sour-bitter taste to the final product, and it is necessary to add seasonings to mask these flavours. Chhaachh made using buttermilk is very healthy but the taste is not relished by all. However, if proper seasonings and spices are used, it can be delicious. This type of Chhaachh is more unusual and rare compared to the other types, because it is available only when butter is churned at home.

Seasoning and flavours[edit]

Chhaachh can be consumed plain, but a little salt is usually added. This is the most common seasoning for Chhaachh. Numerous other seasonings and spices can be added to salted Chaas, either singly or in combination with each other. These spices are usually roasted in a wok, using a spoonful of cooking oil, before being added to the Chaas. The spices which can be added thus are: Coarsely ground and roasted cumin seeds, curry leaves, asafoetida, grated ginger, very finely diced green chillies and Mustard seeds.

Sugar can also be added to Chhaachh, but if sugar is added, than neither salt nor spice can be used. Adding sugar to Chhaachh makes it very similar to lassi, the main difference being that Chhaachh is more dilute (with water) than lassi. Lassi is more popular in Punjab and certain regions of north India, while Chhaachh (known by various named) is popular in all other parts of the country.

Vendors have come up with several proprietary products and standardized flavours of Chhaachh which are produced on an industrial scale and sold as bottled drinks. The best-seller among such brands is Amul's Masala Chhaachh, which has standardized several traditional flavours for the mass bottled-drink market. Other popular modern flavours available as bottled drinks include rose-flavoured "Chhaachh Gulabi" and mint-flavoured "Mint Chhaachh". Both have added sugar and differ from flavoured lassi in being more dilute and less expensive.


In India, the consumption of chhaachh has cultural resonances and associations which are not found in the context of other beverages like tea, coffee or lassi. An earthen pot is used to prepare chhaachh and store it for a few hours before consumption. The use of an earthen pot makes the chaas cool even in summer. In the extremely hot desert areas of Gujarat and Rajasthan, people consume chhaachh with salt after getting exposed to the sun because this may aid rehydration. Chhaachh is consumed all year round. It is usually taken immediately after meals, but is also consumed on its own as a beverage.
