I started using a "whitener" in my coffee because it is supposed to be less apt to stain your teeth. Prior to that, I always drank it black. I do not use all those fake creamers because of all the stuff that's in them. I've tried, and do not like, soy milk or almond milk. That's just to drink straight - I just don't like it but it might be good in coffee. I would definitely stick with organic, though.
What I actually do is use 1% organic milk. I use a frothter to whip it up and I sprinkle a little cinnamon/sugar combo on top. The frother I use is this

At one time I used the canned condensed milk and I liked that but it also has 'stuff' in it that it would really be better not to ingest so I switched to the 1% milk.
I've been doing this for several years and really enjoy it.
