Packet coffee that actually melts in a Jetboil is the whole trick on a multi-day trip, otherwise you are fishing grit out of the lid at dawn.

Instant espresso packets usually hold up once the creamer goes in, and they weigh almost nothing next to grounds. How many days are you out, and are you boiling just for coffee or cooking in the same pot?
