Mumbai-based startup Kefir Culture makes Kefir-based milkshakes. Unlike yogurt-based drinks that provide temporary relief to digestion, Kefir has multiple beneficial yeasts and bacteria that stay within your gut and colonise to provide you with optimal digestive health. It is 99 percent lactose free, and even lactose intolerant people can enjoy the long list of benefits provided by Kefir. Most of the startup’s raw materials are sourced locally, and the most essential ingredient – milk - is procured from a farm in Maharashtra. Each batch of milk is then sent for a two-day manufacturing process in a temperature-controlled sterile environment. Later, this processed milk is refrigerated less than four degrees temperature. The products are distributed across Mumbai and neighbouring districts through in-house reefer vans, and are sold directly to the customers at home, or can be ordered online through their website. One can also opt for subscription models on their website.
