11 In North America we all know when the waitress shows up at the table with an orange spout and handle on the coffee pot, she's about to pour us decaf, coffee with reduced caffeine. But what exactly is caffeine?

The tree has its own defense against bugs by naturally having caffeine in the beans. There are several types of bugs that really seem to prefer coffee trees. In the past few years, researchers have found a species of coffee tree that is naturally caffeine free. There is hope that that species can be crossed with others to produce coffee beans that don't have caffeine.
Here's a little trivia about the orange color representing decaf. No one really knows for sure but some say that decaf and the color orange association goes clear back to 1920s when Sanka made decaf coffee for the first time and wanted to make it very identifiable to the public. Another theory says that when people get out of bed and go to the kitchen to make their first cup of coffee, they see bright orange and even in their disheveled, zombie state, they recognize that bright orange color means they aren't getting real coffee. Another famous company, Folgers, associated the color green with their decaf coffees. Now you'll find several coffee companies associate the color green with decaf but orange still prevails in the restaurants and when serving the liquid nectar of the gods.
