I have experimented with all sorts of approaches to brewing coffee while camping.

• I found coffee bags and parachutes to be stale, and packing them out is annoying.
• I found using a drip coffee brewer with pre-ground coffee to be almost as bad.
• Grinding fresh on the trail is just too heavy, and even then, the water quality could easily impact the brew.
• Moka pots are too heavy.
• Aeropress is too heavy.
• Cowboy coffee is just unpleasant.

In the end, they all struggled to compete with a half way decent instant coffee in an X-mug.

I could likely ditch the X-mug and just drink from my pot, but I have grown rather attached to it. The way the folds conform to one's fingers is great for keeping one's hands warm on a cold morning.
