The world class dripper with a unique close thermo system designed by Stefanos Domatiotis, World Brewers Cup Champion and produced by Brewista. It creates a stable water flow and traps steam and aroma, creating an aromatic and consistent brew suitable to use it at home, at the office or at your coffee shop. The fundamental feature of the Gem Series design is a lid that is placed atop the brewer with a hole that naturally restricts the hot water pouring radius, resulting in a more consistent bloom phase and more even contact time through the brew cycle, while minimizing the common human error of imprecise pouring.
