Fellow set out to develop a new method to brew coffee instead of the traditional French Press route. The Duo Coffee Steeper works by using full immersion to give you the best tasting brew possible. To make your coffee, just add your grounds and hot water to the upper stainless steel chamber, stir, pop the silicone lid on, and let it sit for a few minutes. Once steeped, twist the top and that releases the fresh coffee into the glass carafe on the bottom. Easy peasy. Duo makes up to four cups of coffee and you can make it hot or cold. Best part, it’s all dishwasher safe.
