7.3.6AquaPrima water filter
Water quality
Coffee can only taste as good as the water with which it is made. A
The optimal pH value for a good cup of coffee is in the neutral range of between 6.5 and 7.5. Coffee will taste bitter if the pH is higher. On the other hand, if it is lower coffee will take on a slightly tart taste.
Water hardness defines the lime content of water. It is indicated in degrees of German hardness (°dH). The optimal water hardness level should be more than 7°dH to 8°dH. If the water is not hard enough the flavouring will not have sufficient aroma carriers. The result: coffee will taste bland.
Hint: If the water is too soft, i.e. if the pH level is below 6°dH, simply mix a pinch of salt with the coffee in the filter paper. This will release the flavour into the coffee without leaving a salty taste. If the water is too hard, it would be advisable to use the AquaPrima water filter. This filter optimises the pH value and the water hardness.
