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.

I hear the Hario power kettle is supposed to wipe the floor with the bonavita but I have yet to use either. The power kettle has the aesthetic win in my book though.

Does the Hario have temperature control though? I was under the impression it simply boiled water like a regular kettle.
No, I was talking about their electric version of the Buono kettle with the beehive body and gooseneck spout. I don't know if its variable or not, but in my mind, for a home user only doing manual brewed coffee (rather than tea), waiting ~45 seconds to cool to proper temp (even monitoring temp with an external thermometer) isn't that big of a deal... The spout, however, is much more important for controlled flow.

If you're doing teas, though, that require a specific temp profile for its sweet spot, then this is much more valuable.

My two cents.

**Also, I don't think Hario has released this version yet, but I've read form a few who've used it (such as Cole McBride at Visions Espresso) that it is all around a better option for manually poured brew methods.

But with this kettle from Bonavita, you have a) gooseneck spout, b) don't need a thermometer because it has one, and c) don't have to pour right after it finishes boiling, or guestimate on when it can drop from 212 to 204 or whatever because this kettle will brew to your preset temperature and hold that temperature for up to an hour. Seems like big wins all around.
The gooseneck is awesome, but the flow construction makes just as much of a difference in pourover/chemex. I'm not ruling this out, just sharing some of the cons to the many pros you're listing. I've heard all around that Hario's flow restriction on the Buono is noticeably better than Bonavita's.  

The Bonavita has all around great reviews from many highly respected coffee industry leaders. I'm sure it's an amazing piece of brewing technology. I'm just excited that Hario is trying to keep up. :)

Regarding flow restriction, Bonavita has flow restrictors they sell (or may just include in the box in the future) for their goosneck kettles. They're sending me a couple of them to try out.
Excellent, let me know how you like them!
Also- saw your stove top kettle comparisons on Twitter. Thanks for posting those. Very informative!
