This Cafe Ole Rondeo Teapot is made from 18/10 stainless steel which means it provides excellent heat retention to keep your tea hotter for longer. It comes with an infusing basket - when you steep loose-leaf tea in an infuser, there is room for the tea leaves to absorb water and expand as they infuse; this allows the water to flow through the leaves and extract a wider range of vitamins, minerals, flavors and aromas from the leaves than from small tea particles encased in a teabag.
