For tea with heavier astringency, the minerals in the hard water can combine with the astringent substances to form a refreshing taste.
Teas that are accustomed to drinking with milk, such as Assam tea, paired with hard water can perfectly suppress the astringency and bring out a soft taste and a light tea fragrance.
Hard water suppresses the astringency of tea and, at the same time, suppresses the aroma of tea. Decrease the performance of tea leaves and make tea turbid.
