How much caffeine is in a cup of arabica coffee?

Coffea arabica (common name "Arabica Coffee") is one of the most common varieties of coffee seen on today’s market and is widely accessible. However, only a small percentage of coffee consumers know that this coffee type has a naturally lower caffeine count than most other popular coffees. Because Arabica has an approximately 40-50% lower caffeine count than other coffees, the average person can safely consume two cups of non-decaf coffee with the same effect as consuming one cup of a different variety.
