From my personal experience, I have to agree with wapapaloobop. I put a spoon of raw cacao in my morning coffee, because I love the taste. However I drink (and eat no) sugar whatsoever and found the taste disgusting (in the sense of spitting it out) when I accidentally drank from my girlfriends coffee some time ago.

I agree with you. I enjoy straight espresso and good black coffee. If I want to 'sweeten' it I add some milk. When getting coffee at shops I have mistakenly received one of those super sweet caramel, sugar whatever they are called and almost had to spit out the sip.

I wonder if it is learned or if people who like sweets have different taste buds than those who do not. I also like really hoppy beer and bitter candy.

It is partially learned, partially a built-up tolerance.

Anecdata: About three years ago I drastically reduced my intake of carbohydrates, including all forms of sugar and starch. After around two months, I tried tasting some things that I had stopped eating -- fruit juice, a bit of pie -- and discovered that they were horribly sweet to my tongue.
