A regular Hershey bar is 1.55 ounces and contains 210 calories, 13 grams of fat and 24 grams of sugar as well as very small amounts of dietary fiber and iron. The largest size bar Hershey offers is a novelty bar weighing 80 ounces, or 5 pounds.
The Hershey bar dates back to 1900 and is manufactured by the Hershey Company. Hershey bars are so popular in the United States that other companies modify their recipes to taste more like Hershey chocolate, though it is less popular overseas. All varieties of Hershey bar produced in the United States are kosher.
