I normally drink coffee with sugar and milk, although I sometimes buy something new to add. Vanilla, chocolate, something like that, but it isn't very often. At most once per month. What can I say, I like the simple coffee I normally drink. It's an advantage of living in Colombia, there's no shortage of good coffee.
My favorite coffee in the world comes from Colombia. I currently live in Latin America, and I have had the privilege to get invited to several organic coffee farms where I was able not just to explore the farm but also follow every process in the making of great coffee. I learnt that high quality coffee doesn't need any additives such as milk or sugar. It "shines" on its own.
I only drink it with caffeine whenever I have a busy day or I am chasing down my sleep from the night before. I rather French Vanilla, because of that smell of vanilla that is so hard to resist. I like vanilla in anything.
