Anne Rutherford,
I was taught that yogurt (U.S. spelling) is sour tasting because it lacks
lactose which is a natural sugar in milk.
I was told to sprinkle the Yogourt (CA spell) with powdered milk for lactose
sweetening.
That gives it a better (not bitter) taste.
It worked for me.
As to it's bacterial properties, I defer to others in the PIEN.
