The Wacaco Nanopresso is a hand-pumped portable espresso machine that reaches 18 bars of pressure – more than most domestic machines – from something that fits in a jacket pocket. The result is a genuinely rich, crema-topped espresso wherever you happen to need one: a tent, a train, a hotel room that clearly skimped on the coffee. It works with freshly ground coffee as standard, and with an optional adapter, takes Nespresso-compatible capsules too. For those who want to push it further, the Barista Kit unlocks double espressos and a larger water tank. Cases are available in multiple sizes to suit however you've set it up. The kind of thing that becomes completely non-negotiable once you've used it.
