BWT is a leading European manufacturer of water treatment solutions, widely used in cafés, restaurants, and professional coffee environments. Their filtration systems are built to reduce limescale, unwanted flavours, and impurities while maintaining a mineral balance that supports proper extraction.

At Nordic Brew Lab, we see BWT water filters as a practical solution for improving everyday brewing water. They are especially useful when you want better-tasting water straight from the tap, without fully rebuilding a water profile from zero. Compared to demineralising systems, BWT filters offer a more straightforward approach to water optimisation with consistent, repeatable results.
