Does Reverse Osmosis Water Make Better Coffee?

Most of us enjoy a great cup of coffee, but you may not have thought about the impact of your water quality. A cup of coffee is approximately 97% water, so the water used to make your coffee is vitally important. This means that if you have contaminants in your water like chlorine, bacteria or even hard water minerals, it will affect the flavor of your brew.Does Reverse Osmosis Water Make Better Coffee

The Benefits of Coffee Making With Reverse Osmosis Water

Reverse Osmosis provides an ideal solution for all your drinking water needs. This type of water treatment system is designed to transform your tap water into a fresh and pristine beverage. R.O systems can dramatically reduce any hard water minerals and many other contaminants including nitrates, lead, chlorine, and fluoride.

If your water is from a municipal supply, it’s likely that it contains chlorine that is added during water treatment as a disinfectant. Unfortunately, chlorine is one of the easiest ways to ruin your cup of coffee.

According to the Specialty Coffee Association of America standards, you need water with no chlorine, a clear appearance, no odors and a pH level close to 7 to make a great cup of coffee. Reverse osmosis can assist you in almost every aspect of these characteristics, but you may need additional filtration to bring your water pH closer to neutral.

Coffee and Water Hardness

Water hardness and total dissolved solids can have a massive impact on making a great cup of coffee. It goes beyond the hardness level, as the type of minerals in your water is what will alter the taste of your coffee.

A 2014 study published in the Journal of Agriculture and Food Chemistry on water and coffee found that positively charged molecules or cations in water can draw out some aromatic flavor compounds in your coffee.

For example, magnesium in your water can actually enhance the flavor, creating a woodsy taste, while calcium bicarbonate tends to increase bitterness.

The Implications

The science behind making the perfect coffee is surprisingly complicated and extremely subjective. Everyone has their own views and opinions about coffee, and each of us has our own personal preferences. There are a great number of factors including the bean freshness, the coarseness of the coffee grounds, the method used and your water quality. Excellent tasting coffee shouldn’t be the only reason to consider a reverse osmosis installation for your home, but it is a nice bonus. A reverse osmosis system can be used to remove many contaminants from your water that could be compromising its aesthetic qualities and putting your health at risk. With reverse osmosis water, you may even find that you drink more water and skip the juices and sugary sodas, boosting your health further.

If you have concerns about your water quality and are unsure whether a reverse osmosis system is the best choice for your home, you should speak to a water treatment professional. An experienced and fully WQA certified specialist can not only assess your water quality, but also advise you on the treatment solutions best suited to your specific needs.
