Barisieur: The Coffee Alarm Clock That Brews While You Sleep

If you’ve ever slammed the snooze button just to avoid the misery of making coffee first thing in the morning, this one’s for you. For coffee lovers who need their fix the moment they wake up, waiting five minutes—or more—for a brew can feel unbearable. What if your alarm clock didn’t just wake you up, but also had your coffee ready the second you opened your eyes?

The Barisieur is a designer coffee alarm clock that not only wakes you up but also brews a fresh pot of coffee while you sleep. Priced between £150 and £250 (about $195–$325), it uses induction heating and a stainless steel ball-bearing system to heat water and grind beans, all while gently waking you with the soothing sound of bubbling water instead of a jarring buzzer.

What Is the Barisieur and Who Made It?

The Barisieur is the brainchild of British designer Joshua Renouf. It’s not just a coffee maker—it’s a combined alarm clock and automated pour-over system designed to start your day right. The device prepares both hot water and coffee grounds on a timer, so when your alarm goes off, your coffee is already brewing or ready to pour. It’s aimed at urban dwellers with little time in the morning, especially those in fast-paced cities where those crucial early minutes count.

How Does It Work?

Barisieur uses a combination of induction heating and mechanical action to prepare coffee while you sleep. Here’s how it works, step by step:

• You load ground coffee into a drawer and add water to a glass heating chamber before going to bed.
• You set the alarm time via a built-in control panel.
• At the set time, the device activates its induction heater to boil the water.
• As the water heats, stainless steel ball bearings inside vibrate, creating a soft ticking or bubbling sound to wake you gently.
• Simultaneously, the machine drips hot water through the coffee grounds using a basic pour-over method.
• The brewed coffee collects in a glass server beneath the filter.
• An attached milk cooling tray chills milk (if used), and there are compartments for sugar and extra coffee.

Why Would Anyone Want This?

Beyond the obvious convenience, Barisieur taps into the idea of starting your day calmly and ritualistically. The gentle bubbling sound replaces a harsh alarm, and the aroma of freshly brewing coffee fills your room. For many, that sensory combo makes waking up less jarring and more enjoyable. Plus, having your coffee ready the moment you get out of bed saves precious time and eliminates a common morning hurdle.

Is It Safe and Practical?

While innovative, the Barisieur does come with some practical considerations. The heating element and glass components mean there’s a risk of burns if you reach for the device abruptly while still groggy. There’s no mention of auto-shutoff features in the source material, so caution is advised. It’s also not yet widely available for mass purchase, though preorders were reportedly strong during its concept phase.

The device requires you to prep your ingredients the night before—an extra step, but one that the designer suggests can help establish a calming bedtime routine and improve sleep quality overall.

What’s the Cost and Availability?

When it was unveiled, the expected retail price for Barisieur ranged from £150 to £250 (approximately $195 to $325 USD). However, the product has not reached large-scale production or widespread retail availability. Those interested may need to join a waitlist or seek out limited batches during special releases.

It wakes you up with the sound of boiling water and vibrations from steel ball bearings instead of a traditional buzzer.

How much does the Barisieur cost?

As of the information available, the Barisieur is not in mass production or widely available in retail stores. It was previously available for preorder during its concept stage, and potential buyers may need to join a waitlist or watch for future limited releases.

Does the Barisieur have a snooze function or auto shut-off?

The source does not mention a snooze function or auto shut-off feature. The alarm uses the sound of heating water and vibrating steel balls to wake you, and safety mechanisms like auto shut-off are not confirmed.

How do you use the Barisieur?

The night before, you load ground coffee into the drawer, pour water into the heating chamber, and set your desired wake-up time. In the morning, it heats the water, brews the coffee via pour-over, and wakes you with the sound of bubbling water instead of a buzzer.
