The invention relates to a method of producing a yoghurt-based product. The milk raw material is pre-treated normally by pasteurization, de-aeration, homogenization and possible dry matter adjustment. A stabilizer and possible flavourings are also added. A first bacteria culture is added to the milk raw material and the milk raw material is held at a temperature of 37-45°C time. Therefore, a second bacteria culture is added to the heat treated, yoghurt-based product. The second bacteria culture must be of the type which is not active below a give pH. The finished product is packed aseptically.
