What Is A Smart Kettle?

Sage Smart Kettle Review Over 3 Years - The Best Kettle In The UK

We know about smart phones and smart televisions, but how can a kettle be smart?

Smart kettles give you more control over the temperature of the water.

It’s not just a choice between cold and hot, or trying to lift the kettle off the boil at just the right point.

A smart kettle let’s you choose what temperature you want the water to be.

Smart kettles are also designed to be easy to use, with upgraded features compared to your standard white goods kettle.

They cost a lot more, but if you are in the market for a premium kitchen appliance then a smart kettle could be a great option for you.

  • Perfect temperature every time: The smart kettle features exact temperature times to bring out optimal taste and quality of your favourite tea or coffee.

Product Information

Let’s begin by taking a look at the features of the Sage Smart Kettle.

The design is sleek and simple, with a curved handle for a comfortable grip.

It comes in a choice of silver or black so you can choose the colour that best compliments your kitchen.

The most exciting feature of this product is the temperature control.

Five temperature settings let you decide what temperature the water reaches from 80 degrees celsius to boiling point at 100 degrees celsius.

The temperature points are 80 degrees, 85 degrees, 90 degrees, 95 degrees, and 100 degrees.

The settings are labelled based on which drinks they suit best, such as green tea, white tea, oolong tea, black tea and coffee.

This makes the kettle ideal for people who like to drink different types of tea.

The Sage Smart Kettle also has a rapid boil function if you are in a rush so you can still squeeze in a cup of tea or coffee before you head out the door.

There is also a really useful ‘Keep Warm’ feature which maintains the water temperature for 20 minutes.

This is ideal if you want to top up your tea and have a second cup, or if you are making yourself a drink and are expecting a guest to arrive soon.

It won’t keep the water at 100 degrees celsius, as it would need to be constantly boiling and the water would evaporate.

However, it will maintain a water temperature of between 80 and 95 degrees celsius depending on which option you choose.

The lid of the kettle opens with a simple push-button. It is a soft open lid with cushion control, which means it doesn’t just fly open like on other kettles.

This prevents you from getting splashed in the face with cold water from the condensation that has built up on the lid.

It is also safer if you are opening the lid when the water is still warm, as you won’t get hit in the face with a big plume of steam.

The jug of the kettle has a 1.7-litre capacity which is big enough for plenty of drinks or for boiling a bit of pasta. The jug is cord-free which makes it easy to use.

The element is concealed to make it look much neater and sleeker in design. It also has a scale filter to keep that pesky limescale out of your drinks!

When it comes to cleaning the kettle, the lid opens extra wide to make it even easier for you to reach inside. Make sure you wait for the kettle to cool down before you try to clean it!

The kettle has a transparent water window on each side, making it easy and convenient for you to check the level of water at any time.

The automatic sensor means that the kettle won’t boil if it is empty, reducing the risk of fire, injury, or damage. It also turns off automatically when the water reaches the right temperature.

How long does it take for this kettle to boil? When it was filled to the maximum capacity of 1.7 litres it cooked for 3 minutes and 49 seconds, but not many people boil a full kettle very often.

When filled to 1 litre it took 2 minutes and 16 seconds which is faster than your standard white goods kettle.

This kettle definitely stands the test of time. It comes with a 2 year warranty and a lifetime guarantee against defects, and the manufacturers trust in their product is not misplaced.

Is it worth buying a smart kettle? They cost a lot more than a regular kettle for an appliance that essentially does the same thing.

However, if you drink different types of tea then it will make it a lot easier for you to brew the teas at the correct temperature to get the most out of the flavour.

The Sage Smart Kettle is reasonably priced compared to other smart kettles, and it will last you a long time.

Pros And Cons

Let’s take a look at some pros and cons of this kettle to help you decide if it’s the right option for you or not.


  • Variable Temperature – You can control the temperature between 80 degrees celsius and 100 degrees celsius (boiling point) which allows you to make the perfect drinks
  • Cushion Control Lid – The soft open lid has cushion control which means that you won’t get splashed by a buildup of condensation on the lid of the kettle
  • Dual Side Water Windows – There are water windows on each side of the kettle which makes it very easy to see how much water is left in the kettle
  • Keep Warm Function – You can use the keep warm function to keep the water at the perfect temperature for a further 20 minutes, making it easy to top up your tea or make an extra coffee on those tired mornings
  • Wide Lid – The lid of the kettle opens extra wide which makes it much easier for you to clean the inside of the kettle
  • Handle – The curved handle is very comfortable to use and gives you a good grip for controlled pouring
  • Jug – The jug has a capacity of 1.7 litres and it is cordless for easy use
  • Speed – The kettle boils water faster than a standard kettle


  • Gooseneck – This is not a gooseneck kettle, so it is not great for using to pour directly over coffee
  • Energy – The rapid boil function and the keep warm function use up quite of electrical energy
  • Price – Smart kettles are much more expensive than regular kettles
  • Colour – You only get to choose from two colours – black and silver- which gives you limited options in terms of design, especially if you have a colourful kitchen
  • Wifi – This smart kettle is not compatible with Wifi so you cannot use it in conjunction with your smartphone or other devices

Alternative Smart Kettles

The Sage Smart Kettle isn’t the only product worth considering. Let’s take a look at some of the other smart kettles on the market.

The Brewista Gooseneck kettle is ideal for temperature control and for people who are really into coffee. It has a sleek and stylish design and is very easy to use.

The spout is created to form an even flow of water with precision control which helps you to make the ideal cup of coffee. The ergonomic handle is comfortable to grip which gives you even more control as you pour.

The iKettle is perfect for people with a high budget as it connects to your home Wifi.

It is compatible with Google Home and Alexa which means you can boil the kettle without needing to get up from the sofa. It has a large capacity at 1.8 litres and is easy to use.

The KitchenAid variable temperature kettle is another great choice and is more comparable to the Sage Smart Kettle in terms of price and features.

What Should You Consider When Choosing A Smart Kettle?

Sage Smart Kettle Review Over 3 Years - The Best Kettle In The UK (1)

Choosing a smart kettle can be tricky. There are lots of good products available at the moment and it can be overwhelming. Here are some things that you can consider to help you narrow down your choice.


One of the first things you should check is the capacity of the smart kettle.

If you have a large family then it is best to get a kettle with a big capacity so you can make lots of drinks at once, or boil large amounts of food without having to fill the kettle twice.

Most smart kettles have a capacity of between 1.5 litres and 1.7 litres, but there are some that go up to 1.8 litres or even 2 litres.

Keep in mind that the bigger the capacity, the longer it will take to boil the water the more energy you will use.

How Much?

The price is another deciding factor when it comes to choosing a smart kettle. You can expect to pay anywhere from £80 up to over £200 depending on what features you are looking for.

If you want a reliable, good quality smart kettle with a nice design and temperature control then you will probably pay around £100.

Make sure you check out the individual settings and features of each kettle.

Some have more temperature controls than others, so it depends on what kind of precision you are looking for. Some smart kettles are compatible with Wifi and work alongside voice command technology.

Others can be operated using an application on your smartphone. The more technologically advanced the kettle is, the more expensive it will be.



Keep an eye out for design features that you think will be useful. Some kettles have a specialised spout which is ideal for precision pouring when making coffee.

Others have a soft close and open lid which is great for safety. Kettles with a water window on each side are very convenient.

Is the jug cordless? Does it have a good limescale filter? These are all important factors to consider.

You can also read reviews of various kettles to see how easy they are to use and whether customers would recommend them.

This can make you aware of potential snags in design which you could find frustrating if you only notice them once you have already purchased the kettle.

Frequently Asked Questions

Get your last-minute queries answered here!

Why Are Different Types Of Tea Served At Different Temperatures?

The less oxidised a type of tea is, the less heat is required for the tannins to be released. These tannins are what hold the flavour of the tea.

For example, green and white tea should be brewed at a lower temperature than black tea.

What Happens If You Brew Tea At The Wrong Temperature?

If you use an excessively high temperature to brew tea then you could end up ruining the flavour, making it bitter. If the water isn’t hot enough then the flavours won’t be released and your tea will taste weak.

Can You Pour Boiling Hot Water Onto Coffee?

If you pour boiling hot water directly onto instant coffee or coffee powder, then you could end up ruining the flavour.

The water will scorch the coffee, potentially burning it and creating a bitter taste. You can either add a tiny splash of cold water to the coffee before adding the hot water, or use water that is not boiling hot.

Wait for roughly ten seconds after the water has boiled before adding it to your coffee to prevent burning it and ruining the flavour.

What Is The Ideal Temperature Of Water For Coffee?

It depends on the coffee, but it is widely accepted that you should use water at 80 degrees celsius for medium and dark roasts and 85 degrees celsius for light roasts.

  • Perfect temperature every time: The smart kettle features exact temperature times to bring out optimal taste and quality of your favourite tea or coffee.


Once you have decided that you are in the market for a smart kettle, you will be faced with lots of options of products you could buy.

But is the Sage Smart Kettle the right choice for you?

If you are looking for a smart kettle that is compatible with Wifi and can be activated with voice control or operated with a smartphone then the Sage Smart Kettle is not the right product for you.

There are other products on the market that have these features, though they will cost you a lot more and can be quite fiddly to get set up.

If you are really into coffee and want to make the ideal cup of coffee then you might be better off with a gooseneck style kettle.

These kettles have a specialised spout that gives you precision control over the flow of water. The even pour creates a perfectly balanced flavour.

If you are a tea enthusiast, then the Sage Smart Kettle will be right up your street.

The temperature controls are geared towards helping you make the perfect cup of tea, providing ideal brewing temperatures for different tea varieties.

It can still make a great cup of coffee, but the tea will be the start of the show.

The Sage Smart Kettle has some other useful design features that make it easy, convenient and safe to use. It also has a rapid boil and a keep warm function.

The design will look great in any kitchen and the handle feels comfortable to grip for safe and controlled pouring.

One of the best things about the Sage Smart Kettle is that it is reliable and durable.

It has a good warranty of two years and a lifetime guarantee against defects, and you can be sure that it will last you many years.

It is hard to say whether this is the best kettle in the UK as it depends on what exact features you are looking for, but it is certainly an excellent choice and if you purchase this kettle you will not be disappointed.
