The GROSCHE MILANO is the best-selling series of Stovetop Espresso Coffee Makers. These type of coffee percolators are also called moka pots, and are an authentic Italian style of brewing espresso coffee. These moka pot stovetop espresso makers make a rich and smooth coffee that is more dense than regular drip coffee makers, French presses, or pour over. Their cup sizing is in espresso cup sizes - not regular coffee mugs. So, a 6-cup coffee moka pot will brew 6 espresso cups. The MILANO Stovetop Espresso Maker Moka Pots uses ground coffee and are compatible with a variety of stove tops, including gas, electric coil, glass and propane. The MILANO Stovetop Espresso Makers are made of food safe aluminum and come with a certified Italian safety valve to prevent internal pressure build up. The aluminum moka pots don’t work with Induction stoves, while the stainless steel espresso makers, like the MILANO STEEL are induction compatible. We recommend hand washing for all moka pots.
