Great coffee starts with water
Reverse osmosis water is very pure, but too pure for great coffee. The BWT bestmin COFFEE cartridge adds minerals back, including magnesium, a key flavour carrier.
Why you’ll love it
The minerals in water carry flavour. Getting them right means sweeter coffee, better crema and a machine that lasts.
