I’ve got one like that, but in the military. We got little packets of instant coffee in our rations, I’d just pour that in my mouth and drink some water. I think that’s still technically coffee. Tasted like shit but woke you up, first from the taste and then from the caffeine. Mission accomplished, that’s a good coffee in my book.

Getting down those concentrated bitter coffee crystals with semi cool water (that might be a bit mildewey or plasticky depending on the age of the camelbak you’re drinking from) on a long shitty ruck just feels proper.
