FAQs about Water Filters for Coffee and Tea

How can you descale water for the coffee machine?

To descale water for the coffee machine, a table water filter can be used. This filters lime and other contaminants from the tap water before it is filled into the coffee machine. This way, the water becomes softer, and the formation of lime deposits in the coffee machine is reduced, contributing to the preservation of the machine and the improvement of the coffee taste.

What is the best water for coffee?

For coffee preparation, soft, descaled water with a balanced mineral content, especially with an addition of magnesium, is best suited. Magnesium improves the extraction of coffee aromas, resulting in a fuller and richer taste.

What water should you use for filter coffee?

For preparing filter coffee, soft water with a low to medium mineral content is best suited to optimally extract the aromas. A balanced ratio of minerals, especially magnesium, promotes the development of the coffee's flavor nuances.

Which still water should you use for tea?

For tea preparation, still water with a balanced mineral content should be used, with a low lime content being particularly important so as not to affect the taste of the tea. Water with a high magnesium content supports the development of aromas and ensures a fuller taste experience. Both can be achieved with the BWT Magnesium Mineralized Water cartridges.

other hard minerals from the tap water. The MyAQUA Mineraliser can be installed directly in the kitchen tap for this purpose.
