On a quest to brew the perfect cup of joe, your focus may understandably fall on selecting the right roasts, upgrading equipment, and refining technique over time. However, one of the most important variables is often overlooked entirely – the water itself.
Even with the best coffee makers, the mineral composition of your water can have a significant impact on flavour and aroma, and it can vary not only by location but even seasonally. That’s why serious coffee enthusiasts often turn to mineral-enhancing packets such as Third Wave Water, available from Amazon, to help ensure consistency cup after cup.
How Mineral Packets Can Drastically Improve Home Coffee
Third Wave Water Classic Light Roast
Recommended by 2x US Barista Champion Heather Parry, the Third Wave Water treatments are formulated for brewing the best tasting coffee, no matter your brew. They have everything from classic light roasts (pictured), to espresso, to dark roast, and more.
If, when you make coffee at home, it never quite tastes as it does at the coffee shop, even when using the same beans and the best non-toxic coffee makers, it may be your water to blame.
Heather explains, ‘Municipal quality and mineral content can vary wildly depending on the source and geographic location, which affects the finished cup. Worse, it sometimes contains contaminants.
‘In high volume cafes, business owners invest heavily in water filtration and treatment to ensure consistency and high quality, especially across multiple locations,’ she notes.
Packet mineral treatments offer a fantastic alternative to these industrial systems. When using the best home water filters to treat distilled water (available at Walmart), mineral packets ‘add back’ key minerals in just the right amounts for the resulting brew.
It is worth noting that for most of the US, water from your faucet is usually safe to drink and safe for use in coffee machines. That being said, a study by the Environmental Working Group found evidence of several pollutants across the country that may affect your coffee, but most importantly, your health. As a result, they have put together an EWG tap water checker for you to check your local zip-code supply.
Switching to treated water, such as distilled or filtered, and adding mineral packets is a great way to be on the safe side when it comes to both your body and your appliances.
It is quick, simple, and contaminant-free. Plus, this method of brewing is a fantastic way to prevent limescale, prolonging its lifespan, preserving taste, and making cleaning a coffee maker more streamlined. What’s not to love?
