Where the Keurig skips espresso entirely, the Ninja Luxe Cafe Premier automates it, which makes it the most ambitious machine in the roundup. It combines a built-in conical burr grinder with 25 settings, espresso, drip and cold brew in one body, and that matches our grinder-first philosophy better than any other pick. Drip and cold brew come in sizes up to 18 oz, and you can choose double shot or quad shot espresso.
What sets it apart is how much dialing-in it removes, because weight-based dosing and an assisted tamp take most of the guesswork out of the grind, dose and tamp triangle that trips up beginners. Screen prompts walk through every step, and our first lattes were not great, but by about the third try we were getting a decent one, which is a fair expectation for a hands-free machine. Milk comes from a dual froth system (a whisk plus a steamer) with 4 presets: steamed milk, thin froth, thick froth and cold foam.
The housekeeping is thoughtful, with accessories stored inside the machine and water and bean tanks that lift out for easy filling and cleaning. There is no single-filter basket, so you are working with the dual-wall style baskets the machine supplies.
It is not perfect, since extraction and frothing are slow compared with a dedicated espresso machine, the latte setting is buried in the menu, the thin-foam setting runs loud, and the drip tray fills fast. The grinder dial can feel stiff. It is the priciest machine here, and pricing differs by retailer, so shop around.
