Alessi Kettle 9091 is full of carefully considered details and finished design. Richard Sapper, who designed the classically beautiful kettle, wanted the 9091 pan to appeal to multiple senses, which is why he added sound as part of the experience. The kettle has two brass whistles that play a pleasant melody when the water reaches the boiling point. Kettle 9091, designed already in 1982, impresses with its visual appeal, right down to the wavy handle, and is a striking addition to the table setting. Suitable for all heat sources, including induction stoves.
