Ahoy! Welcome aboard Noah's Ark! Preconceived ideas are common everywhere. However, upon closer examination, you will discover that even those about the same topic will vary with locality!
Take milk, for example. In western society cow's milk is what comes to mind, but in the middle east goat's milk is what goes on your cereal.
In fact (much to the astonishment we westerners feel) worldwide, goat's milk is consumed by more people than cow's milk!
While they are similar, they are also different. Following is a brief comparison of the two. Taste is a hard thing to describe. Some people prefer the taste of goat's milk, others the taste of cows' milk. Many say that goats' milk is slightly sweeter than cows' milk while others believe they have basically the same taste.
It is a fact that methods of processing, packaging, and pasteurization as well as the diet of the animal producing said milk can affect the taste of milk.
