No Rusty-tasting Coffee Here

Many people love a good cup of coffee. Depending on the type of coffee beans you grind down, the right coffee is enough to give you that caffeine boost and even provides fun conversations between friends and colleagues. The water is still an important part of the brewing– one that reverse osmosis membrane water filter systems can aid you in.

Chemical Composition

There are things to look for when brewing coffee. According to the Specialty Coffee Association of America, brewing water must be 150 parts per million of total dissolved solids, five grains of hardness, and a pH rating of around seven, which is not that acidic. Furthermore, the water itself must not have any minerals that trigger scaling such as calcium, magnesium, and iron, plus chlorine, which already affects the coffee’s flavoring.

From Bean to Drink

Some manufacturers of reverse osmosis systems have a line of units that are engineered for coffee brewing, among other purposes. These often have parts such as a pre-RO filter, a carbon block, the main RO membrane itself, and a post-RO carbon block. However, make sure that the RO system you acquire is engineered for commercial use; some coffee joints even discourage home RO units for this purpose.

You owe it to your customers to use clean water for brewing coffee. It brings added points to your product or service.
