Sage Smart Kettle Review – One for the Tea

Updated 13-06-2021 – Dan Alvazrez

The Sage Smart Kettle looks like a kettle from the future and in some ways it is. It is a smart appliance that is expertly made by a company that has a long history of making amazing kitchen appliances. It’s no secret that I’m a huge fan of Sage and always praise their devices, that doesn’t mean they are absolutely perfect, it just means that more often than not, their products nail down what they are supposed to do. The Sage Smart Kettle review is going to explore their smart kettle and see if it holds up to other products in the same category.

Sage makes some of the best kitchen appliances around, and I have been constantly amazed by their build quality as well as functionality. It’s no wonder that this site has at least one Sage product in all the top lists. I have already recommended the Sage Oracle Espresso machine and The Sage Smart Grinder Pro among a few of their products and I have a feeling by the end of this Sage Smart Kettle review, I’ll also be recommending this product (hi, I’m from the future, this is exactly what’s going to happen).

Sage has a long history of making machines that are beautiful to look at and provide some smart features. If you’re outside the UK or Europe, the company is called Breville so if you’re reading from North America or any other place, you can get Breville products, they are exactly the same except for the name. The company doesn’t make simple and straightforward machines, usually, they add their own smart twist on a traditional product. The Sage Smart Kettle is one such product, it is smart, it looks great, and has amazing functionality.

I’m writing this review after using the Sage Smart Kettle for one year and while the product has been around for four years now, I only got it relatively recently. I know that the Sage Smart Kettle existed but never had the chance to try it out myself, which is probably because I’m more of a coffee guy than a tea guy. This brings me to the next important point here, the Sage Smart Kettle is not exactly a coffee kettle, it is more so of a general appliance rather than a dedicated coffee making machine. As it is not a gooseneck kettle, it is not suitable for pour-over coffee. I understand that this is a coffee centred website but the Sage Smart Kettle does offer something unique, and I believe it can be a permanent fixture in your kitchen.


Sage Smart Kettle Review

I have used several Sage products both professionally as a reviewer and personally as a coffee lover. I do not own a lot of their products but the Sage Smart Kettle is one of the few that I have not only bought for myself but also gifted to friends and family. So when I say that the Sage Smart Kettle is a reliable product, I have the experience to back that statement up. While I understand one year is not a long time to assess the reliability of a product, around three other people in my friends and family circle are using it and have absolutely no complaints. It hasn’t failed me yet and is constantly impressing me with its smart features.

I also tested Sage products a lot for work, and I’m constantly trying to steal their products from the office inventory. My office orders so many Sage products that I’m surprised they don’t have a Sage made door lock on the store, that’s probably because the company doesn’t make them… Yet. The company is also very trusting of reviewers as well because they usually send out their sample units for us to test out.

 Here’s a pro tip, if a company is eager to send you their product which costs thousands of pounds, it usually means they are very confident that their product is going to impress you. It shows that the company has faith in their own product and is willing to give it out to reviewers without any non-disclosure agreements being signed. It is very rare to see this kind of openness from a big company like Sage, and it is probably one of the reasons why I am always singing praises for their products.


Overall Features

  • Comes with five variable temperature settings ranging from 80°C to the boiling point. Great for coffee as well as tea.
  • The keep-warm function keeps the kettle warm for 20 minutes, so you can have another cup.
  • Comes with dual-sided water windows which makes it easier to view the water levels during operation.
  • The cushioned control is soft open and prevents splashback from hot water.
  • The lid has a wide opening that results in extra easy cleaning.


What the Company Says:

“Coffee and tea release lots of bitter compounds if they’re put into water that’s too hot.”

So it seems obvious to make a kettle that gives you the right temperature for the right ingredients.

The five temperature settings on this kettle are ideal for green, white, oolong and black tea as well as for coffee. These settings take the guesswork out of making the optimal cup. It also has a rapid boil function and a ‘keep warm’ setting to hold the temperature of the water for up to 20 minutes.

Heston’s Tip: When it comes to brewing, the less oxidized teas like white and green tea release their tannins at a lower temperature. If you brew too hot, the bitter flavours overpower the green tea. Conversely, if you brew too cold you don’t release enough flavour from the leaf. The right balance is all about the right temperature.

Because Different Teas Require Different Temperatures

To extract the most delicate flavours, different teas need to be steeped at different temperatures. But how do you get it right without using a thermometer?

Five pre-programmed temperature buttons tell you which temperatures to select for different types of tea. It heats to the selected temperature, turns itself off and, if selected, will even keep warm for twenty minutes after heating. It features a push-button, soft opening lid to prevent warm water splatter, 1.7 L cord-free jug, concealed element, and a scale filter.

Variable Temperature – Different teas brew best at different temperatures. Choose from variable temperature settings. The kettle automatically turns off and also has a keep warm feature.

Slow Release Lid – A push-button, slow-release lid prevents hot water splashes when opening and staggers steam release.

Dual High Visibility Windows – Highly transparent water windows make filling fast and easy. Positioned on both sides for maximum versatility.

Auto-Off – The kettle senses pressure and turns off once boiled or when there is no water in the kettle.


What I Think – Sage Smart Kettle Review

As I’ve already mentioned, I’m impressed by the Sage Smart Kettle, and it is by far one of the best kettles I’ve used personally. There are several features that make it one of the best general-purpose kettles around, let’s take a look at a few of those:

Sage Smart Kettle ٰ Image 3

The Design

The very first thing you’ll notice about the Sage Smart Kettle is its superb design, it looks like something straight out of a science fiction film. Its brushed stainless steel body gives it a premium look. It will look right at home next to other Sage appliances in your kitchen. Furthermore, it is not a huge kettle, so it won’t be a problem storing it inside a cabinet after usage either. Overall, I’d say that the company has really nailed down a design that is not only functional but also pleasing to the eyes. There is a robust handle on the side, the body is made out of sturdy materials and the controls are easy to reach. I understand that the silver colour might not be for everyone but for most people, this is one of the best looking kettles around.


The Temperature Settings

Most people when making tea go with their instincts, and that is a perfectly valid way to make tea, after all, you have the experience. Some people like to have a thermometer to let the water-cooled down to their desired temperature after boiling, it is also a valid way to make sure your tea or coffee turns out to be perfect. Whether you are using an exact science or just going on sheer willpower, you’ll end up with a cup of coffee or tea at the end, but whether it’s great or not it’s not certain.

The Sage Smart Kettle takes out all the guesswork from the equation by providing you with exact settings for temperature control. These 2 settings allow you to select the precise temperature you want and not leave everything up to chance. There are 5 preset temperature control buttons on the interface that include 80, 85, 90, 95, and 100 °C. All you need to do is simply press the button corresponding to the temperature you want and the Smart kettle will take care of everything. Every person has their own personal brew temperature, while these options don’t cover a wider spectrum, there are still better than going with the standard 100 °C.

Keep Warm

There is a nifty “keep warm” button on the interface and once pressed, it will keep the water warm for the next twenty minutes. The point to be noted here is that it will keep the water and the preset temperature except 100 °C. This is because in order to do that it will have to keep the water at a boiling temperature which is not economical or environmentally friendly. It may also damage the heating element inside the kettle. Depending on you where you live, this might be a great feature to have. If you live in a very sunny area, it will be more economical to just turn off the Sage Smart Kettle and heat it up again when you need another cup. However, if you live in a colder area, which is most of the time in the UK, it would be better to use this handy feature.

It is not the most practical feature on the Sage Smart Kettle, but it is always great to have extra features that can come in handy once a while. If your desired brew temperature is around the preset temperatures on the interface, this will be a great feature to use.


Open Sesame

This might not be a big feature, but it is certainly one of the most satisfying ones on the Sage Smart Kettle. Simply press a button and the lid will open softly. You’ll know it’s great when you use it yourself, trust me on this.


Water Level

You are always able to see how much water the kettle has inside thanks to the unique design. The Sage Smart Kettle makes it a lot easier to observe it as well. A very handy feature to have.


The Boiling Performance

It takes around four minutes to fully boil a filled 1.7 L Sage Smart Kettle. Around half the time if you are boiling 1 L of water. Depending on what kind of kettle you are using already, this will be quite a bit faster and easier.


Some Negatives

There is only one feature that is hit or miss depending on the mood of the Sage Smart Kettle. The marketing blurb says that the kettle knows when it is turned on without no water inside and automatically turns off. Seems like a handy feature to have, but it doesn’t always work, at least on the unit I got from Amazon. Whether it is a common problem or not, the kettle sometimes cannot detect if it has no water inside and starts the heating process up. It happened quite a few times during my testing but most of the time it did detect there was no water, maybe the sensor that is responsible for it is defective or maybe the whole feature is half baked.

Another negative I can think of is the high price, coming at £99.99 it is a bit of an expensive purchase.

Parting Words

The Sage Smart Kettle was first brought into the office as a general kitchen appliance. I wasn’t going to review it because it was not on the list but after using it myself and then purchasing it for home use, it is my duty to inform you about a good quality product that is going to serve you well for at least a few years. It may sound like a paid review at this point but once you use the kettle yourself, you’ll truly understand its potential.

The Sage Smart Kettle is one of the most wonderful kettles, whether you are into coffee or tea, this kettle will serve you really well for years to come. It is a bit on the pricier side, but you are getting reliability, functionality, and great performance. Personally, it is the best kettle I’ve ever used and owned, and I give it 10 out of 10 in terms of usage.
