How many calories in one werther's original carmel coffee hard candies?

Look on the back of the bag the candies came in and you will see the calorie content of these candies. You will also find other nutritional information as well. If you don't live in the US, nutrition information is not always required on packaging. My roll of Werthers from a vending machine has no nutritional information whatsoever. Through the joy of Google, I found that one piece has 20 calories.
