The Perfect Cup: Why Water Quality Matters for Your Daily Brew

For many of us, the day begins with a comforting ritual, brewing that perfect cup of coffee or tea. But while we often focus on the quality of our beans or leaves, there’s one key ingredient we tend to overlook: water. Considering that water makes up about 98% of your coffee and 99% of your tea, the quality of the water you use can make or break your daily brew.

Water isn’t just a neutral ingredient, it’s a natural solvent. Its mineral content, pH level, and purity all influence how flavors are extracted from coffee grounds or tea leaves.

  • Too hard water (high in minerals like calcium and magnesium) can lead to bitter, flat, or chalky-tasting drinks.
  • Too soft water (low mineral content) can make your brew taste sour or dull.
  • Chlorine and contaminants, often present in tap water, can leave unpleasant chemical or metallic notes that overpower delicate flavors.

The goal is balance, clean, pure water with the right mineral composition to enhance aroma, sweetness, and body.

The Science Behind the Perfect Brew

According to the Specialty Coffee Association (SCA), the ideal brewing water should:

  • Have a total dissolved solids (TDS) level of around 150 mg/L,
  • Be free of chlorine and contaminants,
  • Have a neutral pH (around 7).

Filtered water that meets these conditions allows for even extraction, meaning every sip is smooth, flavorful, and aromatic. Tea enthusiasts also benefit: pure water ensures that floral, herbal, or earthy notes shine through, without any off-flavors from the tap.

The Watery Difference

That’s where The Watery comes in. Using reverse osmosis technology, it removes up to 99% of contaminants such as chlorine, lead, and microplastics, while re-mineralizing the water with essential minerals like calcium and magnesium,  creating the perfect balance for brewing.

Even better, The Watery dispenses instant hot water at up to 100°C, so you can brew your tea, pour-over coffee, or even matcha without waiting for a kettle to boil. It’s pure, precise, and incredibly convenient.

Once you experience coffee or tea made with clean, mineral-balanced water, you’ll never go back. The flavor becomes clearer, smoother, and more complex, just as the roaster or tea grower intended. Plus, you’ll protect your coffee maker or kettle from limescale buildup, extending their lifespan.

If you’re passionate about your daily brew, start where it all begins, with your water. The Watery ensures that every cup is brewed with purity, balance, and perfection. Because great water isn’t just part of the recipe, it is the recipe.
