I have always looked at instant coffee as being a good way to waste a fine cup of hot water. However a recent test of the stuff found there is some instants that are actually worth drinking. Coming in as the best is Starbucks Via Columbia. But what's cool is some of the names on the list I had never heard of: Jacobs Kronung? Bustelo Supreme?
