Espresso tastes even better this way; we've tested it. If coffee or tea tastes flat and bland, it's not necessarily due to the bean or the type of tea. The water, or rather, an imbalance of minerals in the water, can be just as responsible.

With bestmax PREMIUM and its AromaPLUS formula, you can change that immediately. This groundbreaking innovation for water optimization from water+more restores the mineral balance in water. The essential mineral magnesium particularly benefits from this. It brings out the true aromas of coffee, tea, or cocoa. But bestmax PREMIUM water also performs well on its own. Well chilled, served in a carafe, it makes an excellent companion: free of particles, odorless, and with a balanced mineral note, it is a true delight for gourmets.


With bestmax PREMIUM you can reliably remove carbonate hardness and protect your machines from limescale deposits.




Pure enjoyment, cup by cup or glass by glass – with the innovative bestmax PREMIUM filter candles this becomes reality.

The proven quadruple filtration and bypass water filtration, combined with the new AromaPLUS formula, ensure balanced mineralization with a high magnesium content. This allows the aromas in hot and cold drinks to fully develop.

Filtration through activated carbon also binds organic contaminants and chlorine, thus removing unpleasant odors and flavors from the water. It goes without saying that carbonate hardness in the water is also eliminated at the same time, a matter of course for water filtration specialists.
