ELI5: What is the science behind an “acquired taste”? Is it as simple as your tastebuds getting used to that specific taste?

Nope, it's all about your brain learning to perceive it differently. 

Have you ever been eating something, and then somebody compared the food to something really nasty, and then it started to taste less appetizing? Or noticed how your favorite food doesn't taste that good if you're completely full? 

Our taste buds send information to the brain, but the brain decides how to interpret it. 

Some foods have a flavor that our brain thinks is potentially dangerous.. Bitter compounds, for example, are more likely to be poisonous. So if something tastes bitter, our brain is suspicious. But if we've eaten it before without getting sick, our brain decides that this particular bitter food is OK, and so it tastes better to you.
