The Bialetti Classic Stovetop Espresso Maker features a black insulating rubber handle and knob.  Blending traditional brewing with modern lines and materials, this stovetop percolator is extremely simple to use. Just fill the lower chamber with water and the top integral filter with fine-ground coffee. Then place the pot on the stove and heat until the water boils. Through the dual-chamber design and pressurizing process, espresso quickly rises into the upper chamber of the pot, ready to be served. The espresso maker is suitable for gas, radiant, and electric stovetops, and it provides a pressure-release valve for safety. Its high-quality construction includes a heavy-gauge, 18/10 stainless-steel body and stainless-steel filter basket.
