Now this is a match made in heaven. Introducing the seductive combination of pour over with the convenience of an automatic coffeemaker, the Chemex Ottomatic Coffeemaker is like having your very own personal barista at home! Capable of making enough coffee for a crowd, the brew unit pre-infuses and pluses hot water throughout brewing to allow the grounds to bloom—taking the effort out of pour over! To top it all off, the iconic hourglass-shaped Chemex Classic Series Coffeemaker is compatible and brings elegance to home brewing.

Features and Functionality

  • Pulsing Brew Unit - Just like a pour over, the brew head evenly distributes hot water in pulses to allow grounds to bloom.
  • Hot Plate - The built-in hot plate kicks on after brewing to ensure your coffee is toasty warm when you need it.
  • Temperature - The Ottomatic creates an ideal brew temperature range of 197.6ºF - 204.8ºF.
  • Well Designed - The sleek brew unit combines beauty and functionality with an integrated pre-infusion time, pulsing brew head to evenly bloom coffee and a hot plate to maintain carafe temperature. An elegant wood and leather-tie secure the neck of the iconic glass carafe.
  • High Quality - Crafted from high-quality, heat-resistant glass, the streamlined hourglass-shaped carafe works together with Chemex’s Bonded Filters and Chemex Ottomatic brew system to reduce sediments and bitter notes.
  • Low Tech, High Flavor - Simply switch on your machine and let it do the work of making a smooth and flavorful pour over for you.
  • Carafe Options - Fits the 3, 5, 6 and 8 cup Chemex coffeemakers—bonus, we found it can fit the 10 cup, too!
  • Manual On/Off - This machine needs to be manually operated, including turning it off. While it switches from brewing to heating the hot plate, it lacks auto shut-off.
  • Fragile - Like with all glass carafes, this artistic vessel should be handled with care when using and cleaning.
How Does it Compare?

For Chemex’s first automatic pour over brew system, we were impressed by how simple it was to brew flavorful coffee.
