At our new home, we have hard water. I had thought that the teabags I was buying were just weak, but the internet seems to indicate that the hard water will actually change the taste of the tea to a more chalky taste with some residue.
Two suggestions I have come across are either brewing with bottled water (I try to reduce the amount of packaging I buy so don't want to do this), or brewing the tea double strength (this makes it a little bitter).
What is the best way to get a tasty brew using hard water?
