The Duo Coffee Steeper: Immersion Brewing with a Twist
Operation is straightforward, with a food-grade stainless steel chamber to hold coffee and water at the top of the device and a silicon lid to trap the heat. A slight twisting action opens a drain at the base of the chamber for coffee to pass through a two-stage, stainless-steel filtration process, down into the included heat-resistant glass carafe. A silicon collar at the center of the hourglass-shaped device makes for easy handling, and the filters are easily removed for cleaning. Large enough to brew up to four servings at once, the Duo is designed to be equally capable of overnight cold brewing, as well as to withstand the shock of hot brew over ice inside the carafe for Japanese-style iced coffee.
