Set the stage for your next pour over masterpiece with the Bonavita Cosmopolitan Variable Temperature Kettle. This glass kettle offers all of the control of Bonavita's other gooseneck line with crystal-clear glass walls that make it easy to see your water level (and watch vapor bubbles boil) at a glance. Better, the Cosmopolitan's 1.3-liter capacity is sized just-right for larger pour overs like a 10-cup Chemex.

  • Gooseneck Spout: A low-mounted spout that tapers to an upraised tip limits flow rate and offers accurate control.
  • Medium Capacity: An outsized 1.3-liter capacity brings a little more hot water for larger-format pour overs.
  • Temperature Presets: A dedicated temp preset button between 140° and 208° gives quick access to commonly used temperatures
  • 1° Accuracy: Looking for more control? You can set and save your ideal temperature to the degree.
  • Hold: Hit the hold button to save your temperature for up to 60 minutes.
    • Pros
      • Larger Capacity: The slightly larger size of this kettle means you can do a full-size Chemex and have enough hot water left over for preheating cups or making a cup of tea.
      • Glass: There's something fun about watching steam vapor bubble up out of the water as your kettle comes to temp.
    • Cons
      • A Little Slow: At only 1000W, the Interurban is hardly the fastest kettle on the market.
      • Glass Handle: The Cosmopolitan's glass handle feels a little fragile.
