MORE ABOUT WATER
If there is one thing that who is in the Specialty Coffee industry can agree on, it is that good quality water is essential for brewing great coffee. Do you know that water is the main ingredient in coffee about 98% of your filter coffee?
Water for coffee extraction should: Be odour free and hygienic, please see here below what you should look at when you buy water for coffee.

The absolute crème de la crème of water treatment systems in coffee applications currently has to be reverse osmosis (R.O.). Traditional reverse osmosis systems use an extremely fine membrane to basically strip everything out of the water, leaving you with no hard minerals at all. However some new R.O. systems designed especially for the coffee market feature special blending valves allowing you to blend a variable amount of water that has bypassed the R.O. membrane back into your feed water giving you total control over the exact mineral content.
OUR RECOMMENDATION FOR AEROPRESS INVERTED
People who use the inverted method do so to prevent any premature drip-through of their coffee and to give them complete control over usually longer brew times.
