Here is how it works and who should buy one. - Author: unknowndivide staff - Tags: Design *Unknowndivide may earn a commission from purchases made through links in this post.* Most kettles announce boiling water with a shriek. The Alessi 9091 plays a tune. Its brass whistle sounds two notes, a soft chord that tells you the water is ready without making you jump. It is a small idea, but it says a lot about Richard Sapper, a designer who liked to solve modest problems with real care. ## What it is The 9091 is a stovetop kettle in polished stainless steel. Alessi lists 1984 as the year production started, and calls it the first of its signature kettles, a design that opened a joyful new period for the company. On [the 9091 product page](https://www.alessi.com/products/9091-kettle?ref=unknowndivide.com), Alessi describes it as a polysensory object, meant to end your wait with a pleasant melody rather than an interruption. ## The whistle The whistle is the heart of the design. Alessi explains that it is made of brass, in a shape that had never been seen before, with two small vents holding tuners that produce the notes mi and si, known in English notation as E and B. Sapper took the idea from a childhood memory: the sound of boat sirens on the river Rhine. His goal was a sound that felt pleasant, not anxious like the whistle of a boiler. Getting there was not simple. According to Alessi, Sapper went back to his native Germany to find craftsmen who could make whistles with a low timbre in a very small volume. Alessi describes this as solving a seemingly minor problem in a poetic way, and it is hard to argue. Once you have lived with a kettle that hums a chord, a shrill whistle sounds like an alarm. ## Specs - **Body:** 18/10 stainless steel - **Whistle:** brass, melodic, two tuned notes - **Handle:** black polyamide (PA) - **Base:** magnetic steel bottom suitable for induction cooking - **Capacity:** 200 centiliters, or 2 liters - **Height:** 19 centimeters - **Diameter:** 16.5 centimeters - **Made in:** Italy The magnetic steel base means it works on an induction hob as well as gas or a standard electric stove top. The 2 liter capacity is enough for a full pot of tea or several pour over coffees. ## Who made it Richard Sapper was born in Munich in 1932 and moved to Milan in the 1950s, where he worked with Gio Ponti before a long partnership with Marco Zanuso that lasted until 1975\. Alessi says he chose design because he was equally interested in art and technology, and that he won the Compasso d'Oro eleven times. His first Alessi project was the [9090 espresso coffee maker](https://www.unknowndivide.com/alessi-9090-espresso-coffee-maker-richard-sapper/), the company's first Compasso d'Oro winner. You can see his other work on [Alessi's Richard Sapper page](https://www.alessi.com/collections/richard-sapper?ref=unknowndivide.com). He died in 2015. ## Living with it Part of the appeal of a kettle like this is how it changes a routine. A whistle you dread makes you hover by the stove. A whistle you enjoy lets you walk away, read for a minute and come back when the two notes start to sound. The polished steel shows fingerprints and water spots, so a quick wipe after use keeps it looking the way it does in the photo above. Beyond that, it is a simple object with no electronics to fail, which is a big part of why designs like this stay in use for decades. ## How it compares The kettle most people associate with Alessi is the [9093 by Michael Graves](https://www.unknowndivide.com/alessi-9093-kettle-michael-graves/), with its little bird on the spout. The 9093 is playful and graphic. The 9091 is quieter in look and more technical in spirit, closer to an engineered instrument than a toy. If you want precise temperature control for pour over coffee or delicate tea, an electric option like the [Fellow Stagg EKG](https://www.unknowndivide.com/fellow-stagg-ekg-electric-pour-over-kettle/) does a different job. The 9091 is for people who like to boil water on the stove and enjoy the ritual. ## Who it suits The 9091 suits tea drinkers, stovetop coffee brewers and anyone who wants a kitchen object with a story. It pairs naturally with the 9090 espresso maker on the same stove, and with a [Bialetti Moka Express](https://www.unknowndivide.com/bialetti-moka-express-stovetop-coffee-maker/) if you want a more everyday counterpart. It is not a fast electric kettle, and it does not try to be one. What it offers instead is a well made piece of Italian design that greets you with a two note song every morning. ## Where to buy **Shop the Alessi 9091** [Alessi 9091 kettle at Alessi](https://www.alessi.com/products/9091-kettle?ref=unknowndivide.com) [Alessi 9091 Kettle with Melodic Whistle](https://www.amazon.com/dp/B0007Z8G9U?tag=unknowndivi02-20&ref=unknowndivide.com) [Alessi steel bottom tea kettle, 2.09 quart](https://www.amazon.com/dp/B000PD0LEM?tag=unknowndivi02-20&ref=unknowndivide.com) For more design icons, browse our [design and art hub](https://www.unknowndivide.com/design-and-art/).
