Hi folks!
I recently moved. Where I lived previously, my water supply was from my own well which supplied good sweet water that made superior tea with whatever variety I chose. Where I now live, the water is supplied by the city waterworks. It seems to be a bit harder (more calcium, etc) than my well water was. The tea I've brewed (using the same pot, method and times) still tastes pretty good, but I'm noticing that the surface of the tea soon acquires a dark brown 'skin' that tends to stick to the sides of the pot or the cup. Am I correct in suspecting the differences in water is responsible for the 'skin'? Can anyone recommend techniques for preventing or minimizing the skin?
