Which is the best water to make perfect coffee?

| Lifestyle Product

The best coffee isn’t always about just the best beans, as 98% of black coffee is water. Using the best quality coffee or choosing the right brewing method is not enough. Optimising your water for the right balance of minerals is also a must for that perfect cup of coffee. Because if the water is not right, you will struggle to get that spot-on taste and flavour of the coffee. This is quite a common problem in homes with a hard water supply (those containing higher amounts of hardness minerals) or a water supply containing chemicals such as chlorine, often used to disinfect drinking water supplied to your home. These undesirable elements affect the taste of your water, and when used to make coffee, can affect its taste as well. And one of the main reasons why getting that perfect taste becomes difficult even when you are using high-quality coffee beans.

What type of water can I use for my coffee?

According to an article from the Department of Chemistry, University of Bath: “The Role of Dissolved Cations in Coffee Extraction” ACS publication 2014, water with the right mineral balance is essential for getting the best flavours from your coffee, whether using roasted coffee beans or instant coffee at home. Many areas in the UK have a hard water supply, that can result in limescale build-up in household appliances like your kettle or coffee machine. As well as affecting the performance of your appliances, ordinary tap water can also affect the taste of your water. Differing taste, less-efficient appliances and limescale damage around the home are all too common for those living in hard water areas.

There are a number of alternative solutions available for those people looking to achieve the very best taste from their coffee consistently.

Option 1: Spring Bottled Water

These are the most common types of water that we all have used or encountered in our nearest local or supermarket store, packaged in single-plastic bottles or tetra packs. According to the Department for Environment, Food & Rural Affairs UK “Compare types of bottled water” Guidance, this type of water typically comes from an underground water source and is tapped at a natural or drilled exit, is free of bacteria and pollution, and is bottled at the spring site.

Using bottled water can enhance the taste of your coffee making your drink more flavourful and tasty. The reason is simple, this type of water is chemically and contains the right balance of minerals. Whilst the resulting coffee tastes good the biggest concern for many of us is the impact that, water in single-use plastics is having on our environment significantly.

Did you know, around 7.7 billion plastic water bottles are used every year according Water UK? With the average person in the UK now using 150 plastic water bottles every year, that’s more than 3 a week. Using single-use plastics is detrimental to our planet and choosing the best alternatives is the need of the hour.

BWT not only stands for the avoid­ance of single-​use plastic bottles but also for the treat­ment and refine­ment of your local water. Read more about our Bottle Free Zone and BWT’s mission “For You and Planet Blue”.

Option 2: Filtered Water

Filtered water is the water that has gone through a filtration process to remove unwanted or undesirable elements like heavy metals, bacteria, or other impurities. Exactly what is removed will depend on the filter media and technology used.

Tap water in the UK is safe to drink, but sometimes can pick up traces of undesirable elements when travelling through the supply pipe and our own domestic water system. Or if you live in a hard water area, your tap water will contain high amounts of minerals such as calcium that can cause limescale build-up when heated. Many of these can impair the taste when used to prepare coffee.

There are various types of drinking water filters designed to remove different levels of unwanted elements from your tap water. These filters use different technologies and filter media to help you with specific problems such as removing chlorine for improved taste or reducing the high amounts of minerals to prevent limescale build-up.

Whether you are only looking to improve the taste of your tap water or want to cater additional problems such as limescale formation in your home there is almost certainly a filter solution for you, from a simple carbon block to the most advanced 5 stage filtration cartridges perfect for optimising your local drinking water.

Thanks to BWT drinking water filters, we can enjoy the taste of Magnesium Mineralized Water right in our homes, without the need of buying bottled water every day from the supermarket.

Option 3: Purified Water

Reverse Osmosis is the process of pushing water under pressure through a permeable membrane to help create 99.9% pure water. One of the most common myths about the RO systems is that you tend to lose access to the essential nutrients that are in your normal tap water. Whilst it is true that some UK tap water does contain nutrients, these are easily obtained  in  a well balanced diet which is rich in nutrients. So when it comes to reverse osmosis, the pros can far outweigh the cons.

The Thero 90 and Thero 90 Pro systems are part of BWT’s new range of reverse osmosis systems that can deliver purified water directly to your tap. Pure water that is free from Nanoparticles, Microplastics and even Bacteria.

BWT’s Bestaqua 14 ROC Coffee (Reverse Osmosis Compact) uses the reverse osmosis process that sits at the heart of its system to create the best water for coffee. It not only removes the unwanted substances, but also adds magnesium for an enhanced taste.

Only with BWT, you can get the smart combination of Reverse Osmosis and BWT’s magnesium enhancing technology. This unique and innovative combination allows you to remove undesirable substances whilst at the same time achieving a balanced mineralisation of the water. Perfect water that helps protect coffee machines as well as improves the taste and flavour of your coffee.

Quality of water is essential for brewing coffee

If you’re juggling with the drinking water choices that might be right for your home, rest assured purified water and filtered water can both be excellent choices. The type of water you should choose will largely depend on your preferences and what’s accessible to you both locally and cost wise. In many cases, people choose drinking water solution that delivers the water that tastes best to them, which can and often is largely subjective.

A research co-funded for BWT and SCAE’s Research Committee, “Charting Water for Better Coffee” studied the impact of the magnesium and calcium ratio and found out that it has a noticeable effect on the sensory taste of the coffee.

The experiment conducted, saw a significant difference on the sensory attributes of the coffee when the concentration of magnesium and calcium in the water was changed.

At a ratio of 1:3 (e.g., 25% Mg to 75% Ca), there was a significant increase in the intensity of astringency and bitterness while the perceived level of fruitiness in the coffee was reduced slightly. Meanwhile, the sensory attributes of acidity and sweetness remained constant throughout the experiment.

BWT with its range of water filters and reverse osmosis systems ensures that users can get the right balance of minerals from their tap water, thanks to their patented magnesium enhancing technology. If you are looking to upgrade your water at home for that perfect cup of coffee, here we have listed some different water solutions you might want to consider in your bid for the perfect water for your coffee.
