This new drip coffee maker mimics the movement of a skilled barista's hand, and uses AI to help you achieve a perfect brew every morning

Cosori may be better know for making some of the best air fryers we've tested over the years here at Tech Radar, but now its engineers have taken on a new challenge: pour-over coffee. Getting a perfectly-extracted pour-over coffee calls for just as much skill and care as espresso, and the new Cosori Juni aims to replicate that technique mechanically with a system that mimics the movements of a trained barista within the brewer.
Unlike most drip coffee makers, which shower water over the basket of ground coffee in an attempt to achieve an even extraction, the Juni uses a rotating basket and an extendable nozzle to recreate the movement and speed of a barista wielding a goose-neck kettle.
According to Cosori, this mechanical process creates a 360-degree spiral flow that evenly saturates the coffee grounds while avoiding creating channels that would cause uneven extraction. Better yet, the process is consistent and repeatable, so once you've found the ideal brew settings for your preferred beans, you can be sure you'll get exactly the same flavor profile every time.
"The physics weren't the difficult part," says Pierce Barnard, Head of Product Innovation at Cosori. "The real work was understanding the human element: spending 18 months studying and mapping how skilled baristas move across the coffee bed and translating that motion into a system that can deliver the same result, every single morning."

The Cosori Juni can handle as much or as little of the brewing process as you like, whether you want to keep things simple of refine the brewing technique and temperature to suit your chosen coffee. The Juni can even use AI to help you pick the optimal settings, and warn you if you've not picked the ideal brewing profile. Just scan your bag of coffee beans, and the machine will generate a brewing profile based on the bean type and your chosen cup-size, then invite you to tinker with factors like agitation, temperature flow rate, and pause time.

It's not yet clear whether the Juni will only be able to scan a particular brand of coffee, as is the case with the Lavazza Assoluta espresso machine I tested earlier this year, which can only adapt its brew settings to Lavazza's own beans.
Alternatively, manual mode lets you take control yourself, though if you want a little guidance then the machine's AI can still warn you if any of the settings you've picked are likely to result in an under- or over-extracted drink. For simplicity, there are also one-touch presets for different coffees and roasts.
If you don't like the idea of such tinkering first thing in the morning, don't worry. Like most of the best drip coffee makers I've tested, the Juni has a timer, but Cosori has gone one step further by letting you set different times for each day of the week, and even allows you to set a reminder to prepare the machine the night before.
Despite its complexity, the Cosori Juni costs a reasonable
