What's "an acquired taste"?

Something that it isn't immediately pleasant. You have to learn to like it.

*Something that isn't immediately pleasant.

Typical example of an acquired taste:
Alcohol: Beer, wine and spirits
Few youngsters like it when they first taste it, but after using the stuff for some years you are actually able to enjoy the taste!

Same thing with coffee too...
