Our full review

The Smeg Variable Temperature Kettle brings a rare combination of retro-styled charm and genuine brewing precision to the kitchen counter, standing apart from the brand's standard electric kettles by offering dedicated temperature control for the serious tea and coffee enthusiast. Housed in Smeg's signature 1950s-inspired silhouette with soft curves, chrome accents, and a satisfying push-button interface, this kettle is available in the brand's classic color palette, allowing it to serve as both a functional appliance and a design statement piece. Beneath the nostalgic exterior lies a thoughtfully engineered core built around one central purpose: giving users the ability to heat water to the exact degree needed for whatever they're preparing, rather than settling for a single rolling boil that can scorch delicate leaves or over-extract fine coffee grounds.

At the heart of the kettle's functionality is a set of preset temperature options tailored to different beverages, typically ranging from around 175°F for delicate white and green teas up to a full 212°F boil for French press coffee or robust black tea. A clear, easy-to-read digital display allows users to select their desired setting with a simple button press, while an internal thermostat system ensures the water is heated accurately and then held at that temperature for a period of time, making it ideal for multi-step pour-over routines or for guests who don't all want their tea steeped at the same intensity. The kettle also includes a keep-warm function, so the carefully calibrated temperature doesn't dissipate the moment heating stops, and a soft-opening lid along with an ergonomic, cool-touch handle contribute to a user experience that feels as considered as its aesthetic.

Constructed with a stainless steel body and a water window that lets users monitor fill levels at a glance, the kettle typically holds around 1.7 liters, enough for several cups without becoming unwieldy on smaller kitchen counters. Its 360-degree swivel base, a hallmark of Smeg's small appliance line, allows for cord-free rotation and easy right- or left-handed pouring, while the cordless design keeps countertops looking clean between uses. For coffee and tea gear enthusiasts who care as much about ritual as they do about results, this kettle transforms the simple act of boiling water into a deliberate, customizable step in the brewing process, rewarding those who appreciate precision with noticeably improved flavor extraction and a countertop centerpiece that looks just as good as it performs.

What owners are saying

Perfect for pour-over coffee

I use the 90°C setting for my pour-over every morning and it's been spot on every time. The design also looks amazing in my kitchen.

Great but pricey

Works exactly as advertised and the build quality is excellent, but you definitely pay a premium for the Smeg name and looks.

Tea lover's dream

Different teas need different temperatures and this kettle nails it every time. Green tea at 70°C tastes so much better now.

Solid daily driver

Heats up fast, looks great, and the keep-warm function is handy. Only wish it held a bit more water for when guests are over.
