Demitasse cups and teapots are smaller than full size teapots and cups, and are also used for espresso. A full size teacup will hold about 6 ounces, while a demitasse cup will hold about 3-4 ounces. The teapot that comes with some of our demitasse sets hold approximately 18 to 20 ounces, depending on the style. We carry demitasse sets for every taste, all at fantastic prices. All of these sets are porcelain from China.
