Coffee lovers are an inventive bunch – think espresso tonics, meringue coffee and even coffee butter spread – but, there’s now a new beverage which looks set to reinvent the entire sector; clear coffee.

That’s right, someone has actually invented the world’s first colourless coffee drink.

Created by Slovakian brothers David and Adam Nagy, ‘CLR CFF’ was born after the pair struggled with teeth stains from drinking so much coffee.

As such, they sought out to make a refreshing ready-to-drink beverage that provided the same boost as coffee but wouldn’t affect their pearly whites.

It might look like a bottle of water but the brand’s website promises that it’s made from “high quality Arabica coffee beans” using “methods which have never been used before.”

After spending three months experimenting to crack the perfect formula, the duo insist that CLR CFF has a fresh, aromatic taste that’s free from preservatives, stabilisers and sweetners.

What’s more, it doesn’t require any sugar or milk and still contains an impressive caffeine content of 100mg per bottle.
