Should You Use Filtered Water for Coffee?

If you are a coffee lover, you should have a look at the article. Are you using proper water for coffee? You might have questions on your mind, what does it mean, should I use filtered water for coffee? Yes, it is necessary to have a RO water filter at your home, no matter for family daily use or just for coffee drink, it is the best machine. We all know that coffee is a drink with a little sour taste, if you pour normal tab water into your coffee drink, it will affect the original flavor seriously. Because there are some alkaline which will affect the acid in coffee. So before having water in coffee, you should have it through a RO water filter. An RO water filter can produce water of proper PH for. How does it work? And Keep reading this article you will find out the answer.

 

Water Standards for How to Filter Water for Coffee

Best PH Water for Coffee

pH describes the degree of acidity and alkalinity in an aqueous solution, and an aqueous solution with pH=7 is neutral. Tap water is generally weakly alkaline, while coffee is generally a weakly acidic drink. If you use water with a higher pH to brew coffee, the alkalinity will be strong, and the acidity of the coffee will be weakened. However, strong acidic and alkaline water is not suitable for making coffee.

Best TDS for Coffee

TDS (Total Dissolved Solvents) measures any minerals, salts, metals, or other solids dissolved in water. The unit of measurement is grams per ton, abbreviated as ppm. In simple terms, the higher the ppm value, the more soluble substances in the water, and these substances are likely to cause a low extraction rate when extracting coffee. And the lower the ppm value, the less soluble substances in the water, so the extraction of coffee. The extraction rate will be higher.

 

According to the research of SCAA (Specialty Coffee Association of America), the ppm value of water is ideal between 125-175, so the extracted coffee can easily reach an ideal value of concentration and extraction rate. If the ppm value is lower than 75, it is easy to over-extract; if the ppm value is higher than 225, it is prone to under-extraction. The effect of different ppm values on golden cup extraction

 

Hard or Soft Water for Coffee

Water is divided into soft water and hard water, and the hardness of water refers to the concentration of specific minerals in the water. Soft water refers to water that contains less soluble calcium and magnesium compounds, as opposed to hard water. Coffee brewed with soft water and hard water will have a certain difference in taste. Coffee brewed with soft water has a softer taste, while the coffee brewed with hard water has a more pronounced flavor layer. In addition, when the calcium and magnesium compounds in the water are too high, it will also affect the release of caffeine and tannins. Using hard water to brew coffee is also easy to form scale, which affects the life of the machine.

 

Best Water Filter for Coffee

The RO water purifier is the choice for brewing coffee. It has a built-in mix of organic fiber carbon filter elements, which removes chlorine very thoroughly and restores the water quality to natural and pure. RO is the abbreviation of "Reverse Osmosis", it has 0.0001 Micron filtering hole, can remove most harmful pollutants in water. 99% of the coffee is "water", which the secret key to the deliciousness of coffee. While there is a lot of chlorine in the tap water, and the chlorine has an unpleasant smell. When it was used to make coffee, it will dilute the smell of the coffee and the chlorine will react with the original aromatic hydrocarbons of the coffee, changes the original taste, and the coffee is naturally not pure. If you want to make a cup of fragrant coffee, be sure to use zero-chlorine water from RO water filter. How does it work to filter water for coffee? Keep reading.

 

How to Filter Water for Coffee

Process of Water Filter For Coffee

By applying pressure to the RO membrane inlet water, the osmotic phenomenon is reversed, and the water molecules enter the low-concentration solution from the high-concentration solution, thereby obtaining pure water. The raw water is preliminarily filtered by PP cotton and activated carbon knots and then passes through the water pump. After the water pump is pressurized, the water passes through the RO membrane.

 

How to Filter Water for Coffee

The RO membrane will produce two kinds of water, one is pure water and another is wastewater. The wastewater will be drained, and the pure water will enter the pressure bucket. When the bucket is full, stop the water production work, turn on the faucet to take water, and the water in the pressure bucket will decrease, and continue to make water. There is also activated carbon behind the pressure barrel to improve the taste.

 

Adjust PH of Water For Coffee

What’s more, water contains some weak acid salts, such as bicarbonate and silicate, which bind hydrogen ions in water, resulting in excess hydroxide ions in the water, making the PH of the water weakly alkaline. After passing through the RO membrane, these ions are removed, so without the interference of these ions, the water is theoretically neutral. However, pure water comes into contact with carbon dioxide in the air. After a small amount of carbon dioxide dissolves in water, it forms carbonic acid and releases excess hydrogen ions, making the water weakly acidic. If you have a sparkling water machine at home, put carbon dioxide bubbles in, and the pH of saturated sparkling water can reach almost 5.5.
