Bottled Water VS Filtered Water

Brita Filters

We recently came across a video which shows what a cup of tea looks like when made from water of varying states of filtration. My personal view is that this may need investigating by an independent source.

However, it did get me wondering what a cup of tea would look like when brewed with bottled water. I did think of conducting the experiment myself, a pound on a bottle of water is alright, but buying a brand new kettle just to make two cups of tea is a bit excessive, so I shall have to stick to guesswork.

So here is my guess: there would be so little difference you wouldn’t be able to notice.

What I can ascertain for sure though, is that if you want drinking water that is purer than the stuff coming out of your taps, Brita filters are your best bet – at about 20 quid for a jug, and then maybe a fiver every few months or so for a new filter. Compared to even 40p per bottle of water, there’s no argument.

What do you think? Do you think using bottled water will yield a better cup of tea? Have you got a Brita filter, a bottle of water, some tea bags and a couple of spare kettles? If you’ve got answers, get in touch.

    I was initially quite sceptical about this. As I’m working from home, I thought I’d do a little experiment. This was not exactly scientific for several reasons. I used the same kettle for a start and it has a good coating of limescale in it. I also only ran the experiment once which is hardly thorough.
    I made one cup of tea using non-filtered tap water, leaving the tea bag in for one minute before stirring it 5 times and then removing the bag. Took photos.
    I washed out and then filled the kettle with filtered water from my Brita jug and repeated as before.
    I wasn’t sure I could tell much difference until I looked at the photos. The filtered one was noticeably clearer and didn’t have the bubbles and slight scum that could be seen on the surface of the non-filtered one.
    I’m going to use filtered water in my kettle from now on.

    I use a brita filter but as I live in one the hardest water areas in the country I have to replace the filter every 4-5 weeks, but it’s worth it!
    Not only does it make tea without the scum on the top – when the filter needs replacing it’s very obvious from the nasty residue in the bottom of the mug!
