Caffeine
From Memory Alpha, the free Star Trek reference.
- "The removal of caffeine from beverages has plagued bartenders and restauranteurs for centuries! You can't expect me to solve it overnight!"
- - Quark (DS9: "Nor the Battle to the Strong")
Caffeine is a stimulant present in a variety of foods and beverages, including coffee and raktajino. It can be somewhat addictive to most humanoids (excluding Vulcans) if consumed in large quantities. For centuries bartenders and manufacturers have tried unsuccessfully to create a suitable substitute.
According to Charles Tucker, Zariphean tea had enough caffeine in it to keep a Human awake for three days straight. (ENT: "Breaking the Ice")
As of the 24th century, there was yet to be a decaffeinated raktajino with a decent taste. Quark's attempt to create such a beverage for Major Kira during her pregnancy with Miles and Keiko O'Brien's son failed miserably. Had he succeeded, the new concoction would have been called "Quarktajino". (DS9: "Nor the Battle to the Strong")
