The double-wall glass POUR OVER coffee maker is a simple brew method that delivers a rich and balanced brew with every cup while keeping your coffee hot for a longer time. Slowly pour hot water in a spiraling fashion over the coffee grounds in the cone-shaped filter to evenly saturate the ground coffee beans. This will allow for a balanced extraction. The fine stainless steel filter eliminates the need for paper filters which actually absorb the essential oils, hence robbing the coffee of its true flavor. The coffee will drip into the mouth-blown, borosilicate double-wall glass carafe and in three to four minutes will be ready to serve.
