(Either actually in your travel kit, or else in your dream setup!)
You’re going on a trip: while nothing’s certain on the road, one thing you need is good coffee. What do you pack to ensure you can always brew a good cup no matter what?
Difficulty level: assume there’s easy access to appropriately-hot water wherever you are.
My travel kit matches the kind of travel we tend to do, so there is that limitation;
I have a double-wide milk crate for transport. In the crate goes my Vario, scale, Clever, box of filters, and a bag or two of coffee. Generally the extra space in the crate winds up holding kitchen shit like knives and herbs/spices, as well as various teas for my wife.
