8. Tea
First off, we know tea was a favorite of Captains Picard and Sulu, so that's two points in tea's favor. Regardless of their reasoning, they just look way cooler and more sophisticated than coffee drinkers. A captain just exudes awesomesauce when he/she can sit down with a nice cup of Earl Grey - hot, in the face of the oncoming storm of a Romulan invasion. Tea also provides myriad health benefits, not the least of which is
an ability to help the body recover from radiation. We all know the dangers radiation presents to space travelers, don't we? Sure, sick bay has ample treatments for something as old as radiation poisoning, but a little extra protection is never a bad thing right? So sit down with your finest china and learn to brew some leaves. Yes, you need to do it yourself. The replicators do a fine job of generating a reasonable facsimile, but there is nothing like the real thing. Earl Grey only please.
