PRECISE TEMPERATURE CONTROL FOR ALL BEVERAGE TYPES: Tea varietals such as Black, Green, White, and Oolong require different temperatures to allow their unique flavors and aromas to develop during brewing. The Viante thermal insulation kettle is able to brew at different precise temperatures for all your teas and coffee. As well as baby formula or instant meals. THERMAL INSULATION & COOL TOUCH DESIGN: The body of this water kettle is made of two walls of super safe 304 Stainless steel separated by a vaccum sealed space which is able to keep the target temperature for up to 8 hs with minimal loss. Great to take to the serving table without losing water temperature or needing to reheat. It's also safe to the touch as it never gets hot on the surface.
