Automatic Pour-Over | Precision Flow Control

Meet Juni

Juni is an automated pour-over coffee machine that brews with real barista technique and personalizes every cup to your taste. Tell Juni how your last cup tasted and it refines the next one.

What Makes Juni Special

Theater of Brewing

Brewing you can see, hear and smell. Juni’s open basket puts the whole process on display, the bloom rising, the water pouring in a laminar flow, the aroma filling the room.

Taste Intelligence & Personalization

Juni learns how you like your coffee. Scan your beans for an instant recipe, share simple feedback, and let Juni fine-tune every cup toward your perfect one. Four brew modes, from one-touch to fully custom.

Craft Automation

Real barista technique, automated. A retractable nozzle and rotating basket recreate three pour patterns, with precise control over temperature, water flow, and timing for an even, balanced extraction.

See the Craft in Every Cup

Most machines hide brewing inside a black box. Juni brings it into the open, and turns your morning cup into something you experience with every sense.

See it. Watch the water pour in three distinct patterns, 
the bloom rise and settle, and the coffee bed flatten as the basket vibrates.

Hear it. The sounds that tell you your cup is on its way.

Smell it. The open basket lets the aroma bloom into the room.

Touch it. Start and steer your brew from an interactive and intuitive control panel.

Taste it. Consistently great coffee, exactly the way you like it.

From Effortless to Fully Customized Brew

Juni is as simple or as hands-on as you want it to be. It starts by meeting you where you are, then gets better the more you use it.

Four Ways to Brew

AI Generation. Scan your bean bag and Juni builds a recipe made for those beans, no guesswork.

Barista Mode. Take the controls and dial in every 
variable yourself.

Quick Brew. A fast start to a great cup.

Scheduled Brew. Set the time and wake up to coffee that’s ready when you are.

Taste feedback loop:
After a cup, tell Juni how it landed. Rate the acidity, sweetness, bitterness, and body. It adjusts the next brew accordingly and keeps refining until every cup is unmistakably yours.

Pour-Over Craft, Made Repeatable

Great pour-over comes down to how the water meets the coffee. Juni engineers every part of that contact, so every cup is brewed with precision and consistency.

Three Pour Patterns

A retractable nozzle and rotating basket work together to pour in spiral, circular, and center patterns, matching the techniques baristas use by hand.

Spiral Pour

Even extraction, no dry spots.

Circular Pour

Controlled agitation, balancing extraction and flow.

Center Pour

Low agitation, deeper extraction, fuller body.

Laminar Flow

A smooth, controlled water stream saturates the grounds evenly and avoids channeling.

Vibrating Basket

Gentle agitation flattens the coffee bed for full, even extraction and releases trapped gas during blooming for even saturation.

Precise Water Control

Temperature, flow rate, and volume are dialed in at every stage.

Filter Pre-Wet

An optional step that rinses the filter to remove any papery taste and pre-warms the dripper.

Staged Pouring

Juni adds water in stages to control how flavor extracts. In Barista Mode, you can customize each stage yourself.

From Single Cup to Batch Brew
