Low-TDS water has a higher acidity that can negatively impact the taste of your coffee. The BWT BestMin Premium is a water filtration system designed specifically for restoring the mineral balance of low-salt and low-TDS water. This filter ensures that you have the best water for brewing by removing impurities and infusing it with minerals and Magnesium ions -- an essential flavour carrier.

Restores mineral balance

If your espresso or pour-over tastes flat or off even when you know you have good coffee beans and the perfect recipe, it could be your water. Low-TDS and low-salt water have a massive effect on extraction. They are more acidic and lack key flavour carriers leading to poorly extracted sharp, or sour coffee. BWT BestMin Premium brings back important minerals to the water and adds Magnesium ions which is a flavour carrier.

Best water for brewing

Designed for use downstream of reverse osmosis systems and for producing hot water for beverages, BWT BestMin Premium is the perfect water treatment solution for cafes and coffee vending machines. This filtration system removes particles from and restores important minerals into the water so that it’s optimal for coffee preparation.

Compatible with the BWT BestAqua Coffee

The BTW BestAqua Coffee is a compact reverse osmosis system created for use in cafes. It is an effective treatment for high-salt and high-chloride water and helps protect your equipment from corrosion. It is also best used with the BWT BestMin Premium Water Filter to produce minerally-balanced coffee water.
