I know water is water and you can get it out of your own tap, but I prefer a sparkling water.
My own home grown water from the tap is Norwich water which is absolutely lovely but as stated, I prefer a sparkling water. Having tried nearly all of them, I discovered they were either too fizzy or too salty tasting and nearly always far too expensive.
I first came across Isklar in my local Tesco. It was on offer, so bought a pack of 6 x 460ml and discovered that this water was the one! Then the price went back to normal and they also had no more stock, saying 'it was too expensive for the average consumer'. I have since found that Isklar is the second best seller in the world, so maybe they couldn't get anymore themselves for the price they were prepared to pay. I was then amazed to find that Amazon sold it and the price at the time was £2.60 in Tesco for a pack of 6, but Amazon was selling them for £5.70 for a pack of 24. I immediately bought 4 cases and now the price has jumped again and they have no stock.
Maybe the glacier this water comes from has melted away....I surely hope not! I highly recommend you try Isklar, cos at Amazon's prices you cannot lose.
