David and Adam Nagy, a pair of Slovakian brothers who enjoy their coffee strong but not coffee stained teeth Have decide to solve the problem themselves. It's clear coffee.
Made from Arabica coffee beans and purified water. With no artificial flavors or sweeteners.
After about three months work and unconventional methods. Success was theirs.
The nutrition facts say a 200 milliliter bottle contains water,fresh coffee,caffeine with less than a 1/10 of a gram of fat.

What does it cost you ask? About $4.00 a bottle, not cheap.
