Then what? Cowboy coffee? Filters? Instant?

I have an old aluminum perk that I use for car camping that simply makes great coffee but I'm not willing to haul such a piece of hardware around in a pack. So, I use a setup like yours and spoon the grounds either directly into the water (cowboy), or, pre-make some filter packets. If I'm really trying to cut weight and trash, it'll be Folgers instant. I have a friend trying to talk me into Starbucks Via packs but it seems pricy for what you get. Esbit or cook fire for heat.
