We've mentioned the standard Bonavita Gooseneck Kettle ($42) before, but the kinds of coffee nerds who experiment with AeroPress recipes are likely to want very precise temperature control. And that's exactly what the Bonavita Variable Temperature model ($90) brings to the mix.

It rocks the same 1-liter stainless steel design and distinct spout that allows for greater pour control, with the addition of temperature control and a few other goodies. You can set your own temperature or use one of the six presets available, then have the kettle hold that temperature for an hour. There's also a count-up timer to help you brew even more accurately.
