Whether you're courtside at Wimbledon or enjoying a summer's day in the park with your mates, it's important to keep topped up with the clean stuff this summer.
Our panel finds out whether tap water can hold its own against its fancy-schmancy bottled rivals.

THE BLIND TEST - Tanousis: “You can tell it contains lots of bicarbonates as it’s quite heavy on the tongue. It’s dull as hell and kind of stale-tasting.”
THE SCIENTIST SAYS - Bell: “This is at least 500 times pricier than tap water, but it does not taste 500 times better. It’s for people with more money than sense.”
OUR VERDICT - Dan: “Describing water as ‘silky’ sounds mental, but in this case it’s true, and not in a good way.”
Pumped into every home in Britain by one of 23 privately owned water companies. Our panel tasted Thames Water, which supplies the South East with 2.6 gigalitres a day.

THE BLIND TEST - Tanousis: “It tastes like swimming pools – stale and offensive. Definitely tap water. This will hydrate you, but it doesn’t stand up in terms of taste.”
THE SCIENTIST SAYS - Bell: “The chlorine flavour comes from the cleaning process, but British tap water has such high levels of regulation that there’s no doubting its quality.”
OUR VERDICT - Dan: “Loses on the taste front, but for sheer environmental friendliness and value, it’s pretty darn good.”
House water at several three-Michelin-starred restaurants, including Heston Blumenthal’s Fat Duck and The Dorchester. Consistently tops blind taste tests by snobby sommeliers.

THE BLIND TEST - Tanousis: “Very clean, well balanced and soft, which means a high calcium content. I’d guess this is Whitehole Springs. It tastes as water should.”
THE SCIENTIST SAYS - Bell: “This tastes the cleanest, but they’re all subject to the same bottled water regulations. You’d have to have a very sensitive palate to tell.”
OUR VERDICT - Dan: “You’d think it’d be nigh on impossible to taste any difference, yet this water is a wet dream.”
Chunks of 12,000-year-old floating ice are collected in nets to melt naturally in tanks. Supposedly free from modern pollutants, it’s the only iceberg water in the UK.

THE BLIND TEST - Tanousis: “This actually dries the sides of your tongue out, like that stuff they squirt into your mouth at the dentist. Not thirst-quenching.”
THE SCIENTIST SAYS - Bell: “You can taste the polar bear as it sinks into the sea from its melting iceberg… Given the world we live in, it’s bizarre people are drinking this.”
OUR VERDICT - Dan: “If ever there was liquid proof that price is not an indicator of quality, this is it. Nice bottle, though.”
Owned by Danone, the same megabucks corporation as sister brand Evian, Volvic bottles more than a billion bottles a year before exporting it to 60 countries.

THE BLIND TEST - Tanousis: “This one’s got a natural coolness, like I’ve just put my tongue in a mountain stream. If I had to guess, I’d say it was the Iceberg Water.”
THE SCIENTIST SAYS - Bell: “Yup, tastes like water. These bottles take about 400 years to degrade, or they can be incinerated, in which case they release pollutants.”
OUR VERDICT - Dan: “The best bottle on the high street – thirst-quenchingly perfect for a hot summer’s day.”
So there we have it...the rest is up to you.
