I've probably said this before, but if I'm the only one drinking coffee (which is actually pretty common), I take my own "coffee singles."  I've purchased the unfilled bags (I use a product called "T-Sac," available from a variety of on-line stores in a variety of sizes) and my normal coffee.  Depending on my mood and amount of available time pre-trip, I'll either take the components or pre-fill and seal the bags.

If I have other coffee drinkers along, I take my coffee press.

In either case, my morning cup(s) are consistent with my normal "back-in-the-world cup(s).  Can't start the morning off right without that cup of joe!

Many years back, I made perk coffee but I dont' have the patience for that any longer ... give me some hot water and I'm on my way!
