Why Is My Homemade Yogurt Sour. An astoundingly thick and creamy yogurt. The result was very surprising.
Both are from the lactic acid bacteria group. The reason yoghurt coagulates is. As an experiment I used a scoop of Fage greek-style yogurt as the culture for my last batch of yogurt.
Yogurt is sour because of the process of fermentation whereby lactose bacteria make energy by breaking down lactose to glucose and galactose.
Ive just begun making yogurt at home. Regarding this why does Curd get slimy. Yogurt can taste very sour and to some people sour tastes bitter. To achieve a less sour flavor culture at the lower end of the range or for a shorter period of time.
