Water temperature is very important when brewing coffee because it affects how your coffee dissolves and ultimately the tastes. If your water is too hot or too cold it can cause your coffee to taste bitter, sour or flat.
I’ve been using the Hario buono kettle for a few years now, and I love it, so when I heard they were coming out with a temperature controlled kettle I was super excited. It’s something I’ve wanted for quite some time.
After testing and using this new Hario Buono Electric Kettle for a couple of months now, I wouldn’t really want to use anything else. It has made my brewing routine so much more convenient and accurate because it saves me waiting for my boiled water to cool down, or using a hob or kitchen kettle to transfer my heated water into a regular gooseneck kettle. The electric buono temperature controlled kettle requires almost no monitoring or double handling and you don’t need to use a thermometer spike anymore!
It essentially has three steps, so it’s really simple to use:
- Press "power on" button
- Use “up” and “down” arrows to set desired temperature
- Press “Keep-Warm” button
The discrete digital screen is really clear showing the temperature, alternating between the current temperature and the desired temperature it is set to (see video vlog review above).
Even though your can set your desired temperature, I generally boil my water first. So my routine for using this electric kettle has one more added step than you might choose. My mother was born in poverty stricken China where water was fetched from dirty water wells, so when she came to New Zealand as a teenager (where I was born) she was very particular about water and the impurities that might be in it. Even though the waters in NZ are some of the clearest and cleanest in the world, there were still problems like giardia in some parts, and even if it’s treated so that it’s safe to drink, you can still taste the chemicals used to clean it.
It was very important growing up to bring any water to be drunk to the boil… I think I inherited this “habit”…So to keep my conscience clear (and my mother happy), I do, boil that water first. But you don’t have to!
Luckily, the time that it takes for the water to boil, also gives you time to prepare by weighing out and grinding your coffee. Then using fresh off the boil water, I rinse my filter paper and set the kettle to my desired temperature by pressing the “keep warm” button. Water will have cooled down by then and the kettle will regulate the water automatically.
The kettle will “beep” a few times to let you know it has reached the desired set temperature.
Pressing the “up” arrow will automatically take you to 93 degrees. When you get to 96 degrees (maximum setting) and press “up” button again, it will take you back to 60 degrees. Likewise if you were at 60 degrees and pressed “down” you’d be back at 96 degrees. This is great because it cuts out button-pushing time but also allows you to set your water to a lower temperature if you use the kettle for teas too (60-96 degree range).
I think this kettle is a perfect volume too (0.8L). It is enough to rinse your filter paper and then do a 2 cup pour-over, with out refilling, while still feeling light enough to lift and operate, which aids with pouring.
Other kettles are often clunky or heavy to handle. I have tried other electric gooseneck kettles and regular kettles with a gooseneck spout and while they are all quite sufficient, there is something really unique about the design of the Hario Kettle spout. Maybe it’s the angle or the diameter of the Hario spout, which gives you more control, precision and safety. I also find the handle really comfortable and allows my small hands to have a firm grip! The Japanese really do prove why their reputation for efficient form and function is so good.
I have seen an older version of this electric kettle, which had a flick switch instead of buttons and was apparently still good, but not temperature controlled. It took water to the boil only. I think this newer model is definitely superior as the old model seemed to have a light on one side that told you when it was boiled but if you were left handed you couldn’t have the kettle facing the other way around.
Because this newer model is 360 degrees rotatable, and all the settings are on the base which can always face outwards, it doesn’t matter which hand you are more comfortable using.
Another thing that’s handy is if you leave your kettle on afterwards, it will turn itself off if unused for a period of time. Likewise, if you turn it on to boil and there’s no water in it, it will turn itself off too! So it’s super safe.
The base is light, minimal and space efficient so it takes up little room on your bench or café counter. The cord can be wound underneath the base to shorten so you don’t have long wires sprawled on the bench, or alternatively if you need to pack it away to transport.
I like to try keep factors the same (ie: dose, grind, temperature) and only change one thing at a time to see what makes a difference to my brew. It not only looks slick but on a practical sense it means I have more control over my brew recipe and method. All in all I’m super happy with my Buono Kettle, and I would definitely recommend it for home and café use.
Here’s a link if you want to check it out further. Here
- 18g coffee
- 250ml hot water (94 degrees)
- 3 minutes
Rinse your filter paper. Then grind coffee into the cone and slowly pour hot water in a circular motion into the coffee. The coffee will bloom, and when it starts to drop, keep topping it up with water until 250mls of water has passed through. It should take approximately 3 minutes to complete.
