ELI5 How do humans acquire a taste for things such as wine, beer and coffee

For instance I absolutely hated beer when I was a young drinker but now absolutely love it. That may be because I am from Wisconsin but how does the brain hate a taste but then start to like it?

The palate changes with age.  Bitter is a particularly bad flavor to young people.  This is supposedly because poisonous plants are often bitter, so we evolved to dislike that flavor in our youth.  

Also your enjoyment of the beverage is only partially tied to its taste.  It's color, smell, intoxicating effects, and your memories of other times you've consumed it inform your opinion.

Finally, it's an addictive substance.  Even mild alcohol cravings can convince you that you not only tolerate the flavor, you prefer it.
