This evening I had a chance to finally fool around with Bonavita's Gooseneck Variable Temperature kettle. This was way, way overdue.

This is a seriously impressive piece of technology. I have not done any formal testing on it yet (ie, running stopwatches, using a Fluke temperature probe on it to test accuracy, seeing recovery times, half fill times etc) but I did boil (or near-boil) about 15 pots this evening. What I saw, I really liked.

Build Quality
This is a solid, solid kettle. Nothing creaks. Everything feels secure. The base is nice (it could be a bit more non-slip but I'm not complaining) the button presses secure on the soft-touch panel and the readout is easy to read (a lot better than this flash-photography photograph shows. 

I have another "variable temperature" kettle from Pino, but compared to this Bonavita kettle, the Pino is decidedly old tech. It's as if the Pino is iOS V1.0 and the Bonavita is Android 4.2 Jellybean ;) 

The Bonavita lets you set your brewing to 1 degree Fahrenheit (or 1Celsius). It has a lot of intelligence built into how it gets to that temperature, purposely stepping down the heating coils as it gets closer, so as not to overshoot your set temperature. It has a fantastic hold ability that will also quickly get back up to your set temperature should you need to add more water to the kettle (great if you put in less water than you need for brewing.

It also has a great feature for brewing coffee - as soon as you remove the kettle, the display reads 0 00 which is, you guessed it, a brew timer. Press the + key and wallah, the timer starts counting up, great for those who want to do timed pourover brewing (or in my case, time siphon brews). 

It is quite fast at heating up as well. It's easily the fastest 1l volume kettle I've ever used (its that noticable) and it is almost as fast as my Bonavita stovetop 1l gooseneck kettle on a full induction range stovetop (which is the fastest way I currently have to boil water). 

The kettle is also exceptionally silent, with maybe one caveat - it is so silent in operation overall that you can actually hear the dulled "clicks" sound of when the heating elements are turned on and off while maintaining temperature. 

Probably the best part about this kettle, with all this great technology, is this: the price. It's only $90 in Canada from places like Transcend Coffee ( and from Seattle Coffee Gear in the US (

I'm doing more formal tests and photography work on this kettle.
