Usually, the only drawback to starting each day with an invigorating cup of coffee is the staining that can build up on your teeth. UK-based Slovakian brothers David and Adam Nagy think they have solved that problem with the introduction of ‘CLR CFF’; Clear Coffee ($8) in a bottle!

Using a secret process, they render quality Arabica coffee beans into a potent clear form before blending it with water to a strength of 50mg of caffeine per 100 ml of CLR CFF. Each bottle of this caffeine infused liquid is 200ml (6 3/4 oz.) for a total of 100 mg per serving which is a bit more potent than your average 8-ounce cup of joe.

Most reviewers have reported that this stuff tastes just like a regular cold-brewed coffee. The Nagy’s take pride in making their clearly innovative beverage with no preservatives, stabilizers, sugar, or other sweeteners of any kind. Right now CLR CFF is only available in the United Kingdom at Selfridges and Whole Foods Markets there, or via their website for mail delivery. [via]
