What is the difference between yogurt and milk?
Choosing Milk For Making Yogurt. Yogurt characteristics are not only influenced by the culture used, but by the choice of milk. Milks from different animals and milks processed in different ways can result in differences in your yogurt's thickness and texture. While most milk will culture well, there are some factors to consider.

Which is better for culturing: cow milk or goat milk?
Cow milk is the most popular choice for culturing. Heating encourages the proteins to coagulate, resulting in a thicker yogurt than unheated or raw milk.
