Home Appliances Design Steam Tea Maker by Hakan Gürsu Steam is a stove-top tea maker. It brews tea by passing hot water pressurized by steam through stacked kettles. Reflecting upon tea culture in east, Steam has stacking teapots specially designed for tea preparation. Larger lower kettle is filled with water to boil, and then boiled water evaporates into upper kettle, steeping loose-leaf tea blend rather slowly. When desired amount is collected in upper part, switch on top is turned to stop water transfer. Serving is made using two kettles with poured tea and water to dilute, therefore allowing user to adjust the strength of drink.
