What the Chemex Ottomatic Is

The Chemex Ottomatic 2.0 is the automatic version of the classic pour-over: a heating base that pulses water in waves over the grounds, mimicking a careful hand pour. It brews into the same iconic borosilicate glass Chemex carafe, through the same Chemex bonded paper filters, and handles both hot coffee and iced brewing.

What Touches the Coffee

Everything on the brew side is glass and paper. Water lands on grounds sitting in a paper filter, and brewed coffee flows straight into the glass carafe. There is no plastic brew basket and no plastic carafe lid in the coffee’s path, which already puts the Ottomatic ahead of nearly every automatic machine.

What We Cannot Fully Verify

The machine side is a different story. Water is heated inside the Ottomatic’s base and delivered through an internal path before it reaches the sprayhead, and Chemex does not publish a complete materials list for that tank and tubing. We have not torn one down, so we will not claim the upstream water path is plastic free. If a fully verified path matters to you, the manual Chemex with a kettle is the surest route.

The Plastic-Free Verdict

Brew vessel: fully plastic free, glass and paper only. Machine water path: unverified. We rate the Ottomatic a strong minimal-plastic choice that automates a genuinely plastic-free brew vessel, with honest uncertainty about the internals. For a zero-question setup, pair the manual Chemex with a stainless kettle.

Who It’s For

• Chemex loyalists who want their pour-over on a timer-free autopilot
• Households that brew daily and want glass and paper touching the coffee
• Anyone stepping up from a plastic-basket drip machine
