Pemberton was convinced that the virtues of his drink were the coca leaves and kola nuts. By using these ingredients he focused on a new medical drink. He replaced the wine with essential oils, but the drink was too bitter. He added sugar to sweeten it, but it became too sweet. He decided to add citric acid to counterbalance the overwhelming sweet flavor. His efforts paid off, and he invented a new product. He soon launched Pemberton Chemical Company in partnership with Frank Robinson. Robinson gave Pemberton the marketing knowledge he needed to advertize his product. By putting the names of the two medical ingredients together, Robinson came up with the name Coca-Cola. He also used a unique script to write Coca-Cola which would became its trademark. Pemberton became sick, to what was thought as complications from his morphine addiction.
