MG2+ Technologie BWT

Magnesium makes all the difference

BTW’s innovative Mg2+ technology has revolutionised the processes for softening drinking water, resulting in mineral-rich water with a great taste.


Our patented, award-winning Mg2+ technology marks a milestone in water technology. It forms the basis of the first, and unique, BWT bestmax PREMIUM filtration system, using a 5-stage process that not only softens the water and removes any unwanted particles but also enriches it with magnesium. Magnesium is a valuable flavour carrier that also balances the acid-base level of the water. “Water in balance” is a major factor in achieving the best taste and sensory properties of end products like tea and coffee in the food service and vending sectors.


The BWT water+more Mg2+ technology offers the ultimate experience in coffee taste:


  • Optimum extraction process in the machine
  • Dense, firm crema
  • Full aroma and taste
