If I’m car camping, I love my Stanley All-in-One French Press. You boil the water in the steel outer shell, pour your grinds in, wait 5 minutes, and then insert the press.
Backpacking, I go with my Stanley All-in-One cook set and make cowboy coffee. I use a trick from Cowboy Kent Rollins (a YouTube chef) to minimize the grinds when I sip (because you can drink straight from the All-in-One) - I pour a splash of cold water on top after I’ve let the grounds sit for a few minutes to dissolve in the water.
However, my friend Susan, if we’re at a car camp site with electricity - she plugs in her home coffee maker :). I don’t complain because she usually makes the coffee for us when she has the coffee maker with her.
And by us - I mean, she has her 1 cup and I drink the rest of the pot.
