Camp wasn't coffee - it was chicory.
I used to stir it into cold milk - much better than making it with hot water.
I prefer Kenco Instant, boiling water poured over. I now have a Breville one cup hot water dispenser (can't call it a kettle). Much faster and the same effect. It definitely tastes different.
Much to the annoyance of a lass I lived with. She said "Coffee boiled is coffee spoiled" - we disagreed on other things as well.

Decaff as we speak.
