We recently travelled from Phoenix to Grand Teton and Yellowstone in a quick summer trip with all our little beans. Five packed, long days means we needed fuel for the road. We always bring a coffee station with us and try to keep it as simple as possible. Our ingredients list for the easiest travel coffee are:

Beal Beans (we bring a variety to keep it fresh)
Grinder (you can get a cheap burr hand grinder online or splurge on a battery powered one. We also brought our Ode in its box because why not?)
Extraction method (V60, is easiest, but an Aeropress, or French press are also good travel choices
Filters
Water (can be collected on the way)
Reusable Coffee Cups
Kettle
Heat (we travel with a mini propane setup but in a pinch you can get hot water from a drive thru or a motel coffee maker)

Road trip!
