Portafilter, capsule or portable: which espresso type is right?
Portafilter machines (De’Longhi Dedica, Sage Bambino) deliver real espresso from your own ground coffee with milk foam: best quality, low cost per cup, but some practice needed. Capsule (Nespresso Essenza Mini) is simplest and slimmest, but with running costs. Portable (Wacaco, Outin) is for camping and travel. Quality → portafilter; convenience → capsule; on the go → portable.
Which is the slimmest espresso machine?
It depends on the type: among the capsule machines, the Nespresso Essenza Mini at only 8.4 cm is the slimmest mains-powered machine. Among the real portafilter machines, the De’Longhi Dedica at 15 cm is the reference. Only portable units such as the Wacaco Nanopresso (7 cm) are smaller still, but they offer no mains-powered brewing.
What does 15 bar of pump pressure mean for espresso?
The pressure forces hot water through the ground coffee and produces the typical crema. For real espresso, around 9 bar at the basket is ideal; the pump figures (15, 18, 19 bar) are maximum values that the machine regulates down internally. More important than the bar figure alone are even extraction and brewing temperature. All machines in the comparison offer enough pressure; the Sage Bambino regulates it most finely with its 54 mm group and pre-infusion.
Can I make cappuccino with a mini espresso machine?
Only the portafilter machines in the comparison have a milk frother: the De’Longhi Dedica (steam wand), the Stilosa (Pannarello) and the Sage Bambino (auto frother). Capsule and portable units make espresso only; for cappuccino you need a separate milk frother there. If you regularly drink milk drinks, you should choose a portafilter machine with a steam wand.
Is a portable espresso machine worth it?
If you do not want to go without espresso on the go: yes. The Wacaco Nanopresso is hand-operated and ultralight (336 g), but needs hot water. The Outin Nano heats itself by battery, is more convenient, but heavier and more expensive. At home they are no replacement for a portafilter or capsule machine, but as a travel companion for camping, hotel and office they are ideal.
