The Perfect Coffee Everytime

Posted by Bluonics Educations on

One aspect of coffee brewing often ignored is water quality. Unfiltered water can ruin even the best specialty coffee. In order to consistently make a perfect cup of coffee, you need to use the right filtered water that will enhance the smells and flavors contained within the beans. Serving coffee beverages with high quality purified water indicates elevated quality standards that customers appreciate in a crowded and competitive market.

What is the best water for coffee brewing?

The best posible water for coffee brewing, according to SCA, has a neutral pH of 7– which helps highlight the often acidic notes found in coffee. The hardness level should be kept low, as little as 1-5 grains-per-gallon (GPG) in order to allow the full flavor profiles to dissolve properly in the water. Total Dissolved Solids (TDS) can greatly affect the taste of your cup of coffee. If your TDS levels are too high, this will mask and reduce the desired flavors. If the TDS levels are low, you will produce a flat tasting cup of coffee. The ideal TDS for the perfect cup of coffee is around 150 ppm.

What can ruin a perfect coffee cup?


The enchanting aroma of freshly brewed coffee is on of the most important parts of the drinking experience. The sense of smell is the first judge when rating a coffee drink. If the water used has any smells of its own, the whole beverage could be ruined despite the quality of the beans or extraction method used. Compounds like Hydrogen sulfide, Phenols, and most importantly, Chlorine will adversely affect the smell and overall taste of your cup of coffee. It is vital to use chlorine free water to brew coffee, even in low concentrations it can be detected by our senses and is sure to overpower other flavors. Most city water supplies are treated with chlorine, making regular tap water inadequate to brew coffee.


Anything but crystal clear water will impact the perception of quality, and possibly also the taste. Tints and cloudiness signal unfiltered dirty water and red or orange colorations means the water contains high levels of heavy metals like iron, copper and rust particles likely from corroded piping. The only color a cup of coffee should have is the natural brownish color, which will vary in intensity according to the roasting process.

Why filtered water is the best choice for coffee?

Filtered water will help enhance the flavors in your coffee, but not all purified water is the same.

To achieve the ideal water parameters, a complete filtration system is needed to eliminate or reduce any contaminants that can interfere in the brewing process. Although there are many filtration methods to choose from, reverse osmosis has proven to be the ideal option. An RO system provides safe, great-tasting filtered water at an affordable price. The systems are easy to install and require low maintenance.


How does a Reverse Osmosis System work?

The RO system works with pressure that pushes tap water through a semipermeable membrane that allows small water molecules to pass, but not larger molecules such as dissolved minerals, sediment, and thousands of contaminants.

What contaminants does Reverse Osmosis Remove?

Reverse Osmosis can remove up to 99% of over 1000 contaminants. 

Such as:

  • Lead
  • Chlorine
  • Fluoride
  • Arsenic
  • Asbestos
  • Calcium
  • Sodium
  • Nitrates
  • PFAS, and many more.
  • TDS (Total Dissolved Solids) are reduced by 90%.




These can be made from yarn, polypropylene, and other materials. Their main job is to capture sediment particles and debris present in water. Sediment filters have different micron sizes to cater to the type of sediment you have. 20 and 5-micron filters are great to capture regular-size sediment particles like sand or dirt while a 1 Micron filter is specially made for finer sediment, such as silt.


The high adsorption capacity of activated carbon makes it an amazing filtering element. Carbon filters remove chlorine and sulfur compounds as well as many other organic solvents and herbicides to provide odorless, great-tasting water. There are 2 types of carbon filters: Granulated and solid. The main difference is that solid carbon filters have more effective filtration and longer lifespan. 



Pressurized water is filtered through a semipermeable membrane capturing most contaminants and allowing clean water to flow through your faucet. It also lowers TDS (Total Dissolved solids) by 90%.



The high energy from UV bulbs makes it an ideal sterilizing method. Eliminating 99.99% of all microorganisms without leaving any harmful by-products is the reason why many choose to install an ultraviolet system. Maintenance is usually very low, requiring a bulb change once a year. The ideal choice for users of well water that need peace of mind knowing their water is properly purified.



The Reverse Osmosis filtration process removes most minerals from the water, even the ones that are needed for the human body. Alkaline filters remineralize water and enhance the minerals in your drinking water and give you better tasting water.

The perfect cup of coffee needs the best water possible. Take your coffee brewing skills to the next level by using only filtered water. A Reverse Osmosis system produces water with the ideal properties for brewing at a low cost. Investing in a filtering water system shows commitment for quality and the overall experience of drinking coffee.
