The Gem’s distinctive design supports and controls water flow for superior extraction, more robust flavors and quite simply, a perfectly-brewed cup of coffee. Designed by the Brewista team and World Brewers Cup champion Stefanos Domatiotis, the Gem Series Dripper helps you create an immersive coffee experience in minutes, from the comfort of your home. 

With a lid fully covering the cone, a small hole at the top of the Diamond naturally reduces the ability to accidentally pour down the sides of the filter paper with imprecise pouring. This small radius of pouring increases the consistency in your bloom phase, from brew to brew, as well as lowering the heat loss of the slurry throughout the process.

Stefanos added the usual vertical ribs and horizontal ribs on the brewer’s inner walls. This helps break up clumped grounds at the bottom of the brew bed and allows water to flow steadily through by providing a small cavity between the paper filter and the inner wall of the brewer.


  • Filter lid with hole for higher kinesis and heat retention
  • 2 sets of filter ribs for flow support
    • Horizontal Ribs
      The horizontal ribs starting at the top of the brewer, slow water flow to increase contact time with the coffee
    • Vertical Ribs
      Deeper vertical ribs go down to the hole, allowing a consistent flow and preventing over-extraction and staling.
  • Wide lid to fit cups and servers
  • Diamond shape for optimal extraction
  • Premium porcelain 
    With Superior Heat Retention and maximum thickness to the walls.

    The Hood on the Gem promotes the brewer to be more specific in their pouring, increasing the chances of a smooth and sweet brew.
