An "acquired taste" is something that most people don't like at first, but slowly start to like more and more as they become used to it.
Beer is a great example of "an acquired taste" because most people don't like it the first time they taste it. But later they start to like the taste.
Other things can also be called "acquired tastes". Here are a few examples:
- music that's really loud and annoying at first
- a TV show that's hard to understand for the first few episodes
- a person who tells rude jokes but is really kind and helpful when you get to know them
