Photog said:So if you have water at the right temp, exactly what is wrong with the "Coffee Singles" (coffee in a large tea-type bag)?
I guess it comes down to what your standards are. Who knows how long ago those beans were ground? It's a simple fact that once ground, the beans deteriorate pretty quickly. Even whole roasted beans don't last that long once roasted. If instant coffee does it for you, great. Just realize that that stuff is on the bottom of the scale of what coffee can taste like.
If I'm limited so that I can't bring somewhat newly ground coffee on the trail and brew it with my french press, I'll just drink tea. Tea has a much longer shelf life than coffee, so I'll bring tea bags along if I'm backpacking and weight is critical.
