The announcement on Wednesday doubles the original proposal of a 1 cent tax and will raise €240 million for public coffers.
Diet drinks like Coke Zero will be exempt from the tax. Fruit juices and mineral waters will also be spared. The tax has been presented as both a revenue-raising measure and an attempt to combat growing obesity.

After ministers accused the company of "blackmail" it quickly backed down and confirmed the investment would go ahead.
Like many countries, France has a growing obesity problem. Latest figures give France an obesity rate of 14.5 percent, up from 8.5 percent in 1997.
The soda tax follows a new levy imposed by Denmark on foods with high fat content. The tax, which came into force on October 1st, increases the price of products by €2.15 per kilogram of saturated fat.
