Tuesday is National Coffee Day in the United States, a day to honor everyone's favorite morning beverage, whether it's taken iced, black or in Frappucino form. The average coffee drinker consumes 3.1 cups of coffee a day, and if you're among them, this is your time to celebrate.

One of the most famous origin stories about coffee involves an Ethiopian goatherd named Kaldi, who tried nibbling on red berries -- or coffee cherries -- when he saw his goats try them. Excited, Kaldi took them to a group of local monks, who promptly threw the beans in a fire. The aroma made other monks come running, they stewed the berries in water and news of the drink spread from there, according to the National Coffee Association USA.

Today, more than 150 million Americans drink coffee daily, and about two-thirds of all coffee is consumed in the morning. The average price for a cup comes in at $1.38, adding up to $40 billion spent by Americans on java every year, a 2010 study found.
