Considering the freshness of the beans used, water is the most important part of a great cup of coffee. The average cup of coffee is 98-99% water, with the rest of the 1-2% being the dissolved solids from the grounds.

Proper coffee to water ratio
Using the right ratio of ‘coffee-to-water’ is also important to get coffee to taste right. It is recommended using 2 tablespoons of ground coffee for every 6 ounces of water.
Mineral and pH level
The content of mineral as well as pH level of the water you use can also affect the final product. Using the water that is wrong can ruin a stunning coffee and that is not wanted by anyone. But water chemistry really is not a huge problem. Wisdom is conventional on coffee, if your water tastes good to drink, it will taste good for coffee. Just make certain you are using water that is clean and free of odd odors or flavor. If you wouldn’t drink a glass of it, don’t make your coffee with it.
