I know that a rave about instant coffee is, at first read an oxymoron. I confess to being a coffee snob. I usually only have instant coffee in the woods after being added to my hot coco. BUT I have to rave about a new product. It's instant coffee from Starbucks! It's called Via and it tastes exactly like a fresh brewed cup of good coffee.
It's a little pricy for me, (12 single serve packs for around 9 bucks) But if your coffee is important to you then it may be worth a look.
