Coffee production in Sri Lanka peaked in 1870, with over 111,400 hectares (275,000 acres) being cultivated. The Dutch had experimented with coffee cultivation in the 18th century, but it was not successful until the British began large scale commercial production following the Colebrooke–Cameron Commission reforms of 1833. By 1860, the country was amongst the major coffee-producing nations in the world. Although coffee production remains a source of revenue, it is no longer a main economic sector. In 2014, the country ranked 43rd of largest coffee producers in the world.
