Khlava: A pumpkin colored beverage from the Vland Sector served hot or cold and made from the roasted seeds of a barley like grain plant. The grain is sadly not edible. Most people describe the taste as bittersweet. Solomani (Humans from the Sol System) often add a sweetner and some form of cream. As you've probably guessed Khlava is the Vilani version of coffee. Humans from Vland and Humans from Earth can get into very heated arguements about which is better. Khlava is not nearly as high in caffiene which some think is a benefit, though many Earth starship captains disagree.
(Found, suprisingly enough, on a recent EN World thread.)
