9091 is a kettle from Alessi designed by Richard Sapper in 1983. The classic kettle is made of polished stainless steel with a brass spout and a sturdy plastic handle.

Richard Sapper created the 9091 inspired by a childhood memory – the poetic sound of boat sirens on the Rhine River. When the water boils and the steam reaches the spout, a pleasant melodic tone is emitted. The kettle has a heat-resistant magnetic steel base that works on all types of stoves.
