I love coffee.  It was originally exported from Africa to countries all over the planet.
I have never been able to get myself to like the taste
It's certainly an acquired taste.  Once you start to acquire it, you'll love it.  It's also very healthy if you drink it brewed black.
I much prefer to drink hot chocolate in the winter
I love hot chocolate!  The first chocolate beverage was believed to have been from the Mayans.  It was also essential to the Aztecs.
I wonder if it was always so sugary
If you ever eat a chocolate with a very high cacao percentage, it's a very bitter taste.
That would be gross. My favorite is milk chocolate
