There’s nothing quite like the moment you take your first sip of a perfectly brewed cup of coffee at a cafe. It’s the warm hug of aroma and rich flavour that brightens your day. But here’s the catch: that delightful experience doesn’t just happen by chance.

Ever tried to recreate that café experience at home, only to be greeted by a cup that tastes more like dishwater than the dreamy brew you had in mind? You adjust the grind, switch up the brew time, and maybe even throw in a cheeky motivational “you’ve got this!” pep talk, but somehow, it’s still not quite right. What gives?

The truth is, while your coffee beans deserve some credit, the real MVP of your morning cup is the water you’re using. If you’ve been relying on tap water, you might be unknowingly ruining your coffee’s potential. It’s time to change that!

Why Does Coffee Taste Better at the Café?

When you sip a cup of coffee at your local café, it’s not just the beans or the barista’s skills at play. The water they use is often filtered to make the flavour shine, free from chlorine and other impurities that can muddy the taste. On the flip side, your tap water can be a mixed bag of minerals, chemicals, and gases—none of which do your coffee any favours.


To understand why water quality matters so much, consider this:
your cup of coffee is about 98.75% water. That means the water you use plays a huge role in how your coffee tastes. Using high-quality filtered water can turn an ordinary cup into something special—like swapping out a plain potato for a fluffy baked one!

Hard Water vs Soft Water: Which One Ruins Your Brew?

Now, let’s get technical for a moment. Many people believe hard water is the best choice because it’s rich in minerals like calcium and magnesium. And while those minerals can contribute to a well-balanced cup, hard water also comes with its drawbacks.

The problem is that hard water often contains high levels of bicarbonate, which can bring out bitter notes in your coffee. So, while you might think you’re brewing a robust cup, you might end up with something overly harsh.

On the other hand, soft water lacks the necessary minerals, resulting in a flat and boring brew. The bottom line? Neither extreme is ideal, so finding the right balance is key to brewing a delicious cup.

The Ideal Water for Brewing Coffee

According to the Specialty Coffee Association (SCA), the best water for coffee brewing should have a balanced mineral content and be free from impurities. Here’s what to look for:

  • Neutral pH: ideally around 7.
  • Around 150 mg/L of total dissolved solids (TDS): This ensures the water has enough minerals to boost flavour without overwhelming the coffee.
  • Free from chlorine and other odd flavours: Because nobody wants their morning cup to taste like a swimming pool!


This balance lets the coffee’s natural flavours shine through, giving you the rich, complex taste you love.

Tips for Brewing the Perfect Cup

Switching to filtered water is just the beginning. Here are some tips to make your brewing experience even better:

Use the Right Amount of Coffee: Finding the perfect coffee-to-water ratio is important for a balanced brew. You can follow the Golden Ratio which is about 2 tablespoons of coffee for every 180ml of water, or you can adjust based on your preference.

Temperature Matters: The right brewing temperature is key. Aim for a range between 90°C and 96°C to avoid scorching your coffee grounds. No one wants a cup that tastes like it’s been left out in the sun for too long, right?

Clean Your Coffee Equipment: Regularly clean your coffee maker to avoid limescale build-up from unfiltered water. Using filtered water helps prevent this and ensures a clean brew every time.
