The economics of coffee have always been tumultuous, from unfair to environmentally unfriendly growing practices to labor controversy.
All the private wars of small farmers and large companies boil down to warm Styrofoam cups, gourmet coffees and cutting edge drinks in a dizzying array of colors and tastes usually retailing anywhere from $2 to $4 a cup - black gold.
And the fuel addiction is obvious on college campuses.
"It's always been my experience that 18- to 20-year-olds don't drink that much coffee - but I think I'm being proven wrong," says Ira Simon, director of food and vending services at UNC.
A casual survey of UNC students streaming from class to class shows hands circling cups embossed with trade names that have become synonymous with the product.
"College towns and coffee shops go hand in hand," says Grant Meadows, manager of 3 Cups on 431 W. Franklin St. "Our society is becoming more and more inundated with coffee."
And the aromatic brew saturates at the rate of about 100 pounds of coffee sold a week at 3 Cups. Meadows says about half of that is sold in bulk and the other in takeaway cups.
"We probably go through 65 to 85 pounds of regular coffee a week," says Dominique Soroka, general manager of the campus-based Daily Grind Espresso Cafe .
That figure doesn't include specialty coffees or flavored coffees - which Soroka estimates is about 25 pounds a week.
