pH and Alkalinity Explained:
What is Alkalinity?
Alkalinity is the amount of minerals in the water, the actual mineral concentration of the water. Normally the higher the Total Dissolved Solids (TDS), the more alkaline minerals are in the water, so the higher the alkalinity of the water. Alkalinity is also measured in pH.
Alkaline Water can have high alkalinity but if it’s carbonated it also has a low pH.
Ideally, water should have slightly higher levels of Alkaline mineral (TDS) and a higher pH (say a pH up to 9)…
In theory, a coffee made with water at a pH of 7, makes a coffee at a pH of 5. Therefore, a coffee made from water with a pH of 9, should make a coffee with a pH of 7 – two points more on the pH scale.
