Make the Perfect Cuppa with Filtered Water

A perfect cuppa coffee or tea can kick-start your day. There a many factors that go into making a perfect cuppa; from the origins of the beans or leaves to the techniques used.

Whilst we are not barista trained, coffee gurus, we are experts on one thing; the water quality! Whatever your drink of choice, start with filtered water. Water makes up 98% of your typical espresso, so it makes sense to choose the best quality water source.

The Taste

The taste of your cup of tea or coffee depends on water hardness. There are three minerals that contribute to water hardness; magnesium, calcium and bicarbonate. Each mineral can alter the taste of your cuppa, so it’s important to get the right amount. Too much calcium dulls down the flavour of the beans or leaves. Bicarbonate regulates the acidity of the water, without it the taste will be too sharp, but too much could result in a chalky cup of coffee. Magnesium helps to extract the fruity flavours of the coffee beans. Maintaining a good balance of this mineral ensures you’ll get that perfect cuppa; not too acidic, flavoursome and smooth.

There are other factors that can impair the taste of your favourite tea or coffee blend. Impurities in the water supply, as well as being harmful to health, can affect the flavour profiles. Chemicals such as chlorine, although added to the water in safe regulated amounts, can bond with organic compounds in the water producing harmful by-products, called Trihalomethanes (THMs). In addition to having these THMs lurking in your water supply, chlorine brings its own off-putting smell and taste to tap water.

The Temperature

Whether you drink tea or coffee, freshly boiled water straight from the kettle is not a good idea. It is recommended to use hot (90-96C) and not boiling water to avoid scalding the tea leaves and for a less bitter cup of coffee. As a guide, black tea and coffee require a similar water temperature, but for green tea the temperature should be lower, around 80C.

Hydrogen-rich filtered water has many benefits to health and is the best water filtration solution to opt for. However, if you are looking to benefit from hydrogen water in your hot drinks, bear in mind the temperature. Hydrogen water evaporates at boiling point 100C, so ensure that your kettle heats the water to below this temperature, if you own a variable temperature kettle.


The Time

Of course there are days when you are rushed for time and an instant ground coffee or a builder’s tea will just have to do. For lazy weekends and days when time is not an issue, make sure that you don’t rush the process. Brewing time for teas vary depending on the leaves; for Ceylon, Earl Grey, Darjeeling and Assam, 3-4 minutes should suffice. Delicate Jasmine and Sencha need only 2-3 minutes to infuse.

If you use a cafetiere when making coffee, the standard brew time is usually 4 minutes before you press the plunger. One of the latest coffee trends requires a little more time to brew. The cold brew technique involves steeping coffee grounds for 18-24 hours in cold water to achieve a smooth and refreshing cuppa. For this technique it is especially recommended that you use filtered water for a purer taste. Another top tip is to batch make cold brew coffee and leave in in your fridge, otherwise it can be pretty time-consuming.
