Stovetop espresso coffee makers, also known as "grecas", are still the most popular and effective way of making great espresso coffee at home. These simple machines work by creating pressure through heat to force pressurized hot water through finely ground coffee and into the top holding chamber. This is exactly the same process a very expensive espresso machine uses to brew your coffee, but for a fraction of the price!High quality polished aluminum body, Safety pressure release valve, Capacity: 3 cupsHow to use your stovetop espresso coffee maker?Fill the bottom chamber with water up to the steam release valve (overpressure plug). Do not overfill! This will cause water to come out the valve as it warms up. Insert the filter and fill it with your favorite espresso coffee. It is very important to smooth it (level it) and please don"t tamp it. Make sure the rubber gasket is in place. Screw the top on and put it on the stovetop with enough heat to cover the bottom of the espresso maker. When you hear the greca gurgling, this means that the water tank is empty - simply remove it from the heat and allow it to sit for 30 to 60 seconds. Serve the coffee and enjoy the best tasting espresso available anywhere!
