How would you describe the taste of plain, ordinary water? It has a ph of 7, meaning it isn't acidic or alkaline but you can taste some of the minerals in it.
My cousin always calls it dinosaur wee. He doesn't like it, and ever since he learnt about the water cycle, uses this as an excuse, even though, most of what he drink contains water mixed with stuff.
Water tastes different all over the country. The nicest water I ever remember was when I lived in Birmingham and the water came from a reservoir in Wales. Welsh water is lovely. The worst (with no disrespect to Molly) was in Norfolk when we stayed at the holliday camp in Caister, the water tasted like boggy tangy stuff - that was my first venture into drinking bottled water for a week!
