Gents, I was just wondering what water you use for brewing your teas and coffees. I'd love to use my local tap water but it contains far too many minerals and also has nasty dertergent smell to it. It's not suited for brewing tea or coffee at all and leaves that familiar 'film' layer on top of the tea and the inside of my mugs . Since I don't have any sort of filtering system, I use bottled Spa water from their Reine source in the Belgian Ardennes. So, what about your H2O?? Anyone using tap water straight from the tap with good results?
