The Chemex Ottomatic 2.0 is an automatic pour over machine that heats water to 197.6 to 204.8 F and runs a staged brew over a Chemex glass coffeemaker at the press of a button. Chemex sells the Six Cup Classic set at $350.00 on its own store.
What is the Chemex Ottomatic 2.0?
It is a base and water tank that brews through a standard Chemex glass coffeemaker, so the carafe is the familiar hourglass glass one. Chemex says it manages the key brewing variables for you: pre-infusion, the contact time between water and coffee, and water temperature. You choose a Six or Eight Cup Classic or Glass Handle coffeemaker, or buy it with no brewer if you already own a compatible one.
It fits 3, 6 and 8 cup Chemex Classic or Glass Handle coffeemakers and 3 and 5 cup handblown ones. It cannot be used with the handblown 8 or 13 cup sizes. The box holds the machine, a small pack of Chemex Bonded filters, a glass coffeemaker cover, a coffeemaker cleaner and a brew clip.

How the Chemex Ottomatic 2.0 brews
The Greedy Cup sprayhead runs a staged brewing cycle. Chemex describes a pulsing water bath that keeps the temperature up and spreads the extraction evenly through the grounds. Pre-infusion comes first, which wets the grounds before the main pour, and the machine times how long the water stays in contact with the coffee.
Chemex says the water is heated to the Specialty Coffee Industry target temperature. That describes a temperature range and is not a certification, and the Ottomatic does not appear on the Specialty Coffee Association's list of certified home brewers read on 2026-11-03. A hot plate keeps the coffee warm and shuts off after 90 minutes, and an iced coffee mode is built in.
Cleaning uses Chemex's own cleaner. You fill the tank to the 8 cup level with water and the cleaning solution, run a brew cycle, then run at least two brew cycles with water alone and allow a 5 to 10 minute cool-down.
Chemex Ottomatic vs Technivorm Moccamaster KBGV Select
The Technivorm Moccamaster KBGV Select 10-Cup brews a 40 oz glass carafe on a warming plate, with a half or full carafe switch, a 100 minute auto shut-off and a 5 year warranty. Technivorm says it is certified by the SCA, and it is on the list. Chemex lists none of those: no certification and no warranty term.
The Ottomatic's argument is the Chemex glass coffeemaker, the staged pre-infusion and the iced coffee mode. The Moccamaster's is the certification and the longer warranty. Both use a glass carafe with a hot plate.
Chemex Ottomatic vs Fellow Aiden Precision Coffee Maker
The Fellow Aiden Precision Coffee Maker is listed from $399.95. It has a thermal carafe, a dedicated bloom followed by measured pulses, app control with scheduling, a 2 year warranty and SCA certification. The Ottomatic costs about $50 less and has a glass carafe, a hot plate and no app or timer. If you want automation and a certified brewer, the Aiden has more on paper. If you want a Chemex in your kitchen, the Ottomatic is the machine for it. See drip coffee makers for the rest.
Is the Chemex Ottomatic 2.0 worth it?
At $350.00 it is priced with the premium drip machines, and what you pay for is the Chemex pour over method made automatic. You get a published temperature range, managed pre-infusion and an iced mode. You do not get a published warranty, a timer or SCA certification. Nobody has tested it for this page, so there is no claim here about taste, speed or noise.
The Eight Cup versions cost $2.00 more than the Six Cup ones, and the No Brewer option is $306.50, so owners of a compatible Chemex save $43.50 against the Six Cup set. The Classic and Glass Handle sets are priced the same, so the choice between them is a matter of looks and grip rather than money.
Who should buy the Chemex Ottomatic 2.0 (and who should not)
It suits someone who already likes Chemex brewing and wants a button instead of a kettle. It also suits a household that brews one carafe at a time and drinks iced coffee.
It is not for a buyer who wants a programmable timer, a thermal carafe or a certified brewer. A glass carafe on a hot plate that shuts off after 90 minutes also suits people who finish the pot within the hour.
