BWT bestbarista ROC COFFEE represents a completely new evolutionary step in water optimization for coffee and all kinds of hot drinks. This is the first system in the world to create the best water for coffee whilst remaining completely independent of local water quality.

Reverse Osmosis + Remineralization

Based on the first step of reverse osmosis technology, virtually all minerals and unwanted substances are removed from local raw water. In a unique second step, the optimum minerals for the best extraction are added. In a carefully controlled process, both the quantity and quality of minerals in the resulting, optimized water are fixed.

Focusing on Magnesium and Silicate, the unique combination of minerals ensures a consistent and globally identical quality of water for coffee.

The new E=mc2 formula for coffee water by BWT water+more ensures constant quality for optimum extraction and reliable protection of coffee machine equipment.

E=mc2 is the new worldwide formula for the best water for coffee!
