How is a "good taste" determined

Why is it that some things are just universally accepted as tasting good? Such as chocolate?

As an infant do you have zero predisposition towards any food or is there a way that we determine what tastes good or not?

Is it cultural? Learned? Or hardwired into our brains?

People taste things differently. There's a chemical called phenylthiourea that is either tasteless or very bitter, depending on the taster's genetic makeup. We used to use the stuff in biology class to teach a bit of human genetics. It's been said that cilantro either tastes bad or good depending on genetics. How something tastes to someone can differ wildly to different people. Much of what people taste is really smell, and the sense of smell varies, also.

We naturally want to eat a lot of foods with sugars, fats, and salts because over time we have learned these have the most energy. This was great during the times when us humans had to hunt for whatever, and realized that a plate of mammoth meat gives you much more energy than some daises.

It probably has something to with the fact that a lot of the foods that people say are "good" are really just loaded with sugar (chocolate is a great example), and there are plenty of biological reasons as to why foods loaded with energy would taste good.
