Water

Something I have known forever and now want to declare it! :-
Water that comes from your tap in the Thames Valley (London, Homecounties...) is the best in the UK. It is hard water, which is better-tasting than soft water (Wales), some areas have fluoridated water which means the drinker will benefit from better dental health. Bottled water (Evian, Volvic & ilk) is horrible in comparrison. Totally-tap: Thames Valley tap water is packed with refreshing energy.
