A “coffee estate” is used to imply a farm that has it’s own processing facility, a wet-mill. In Spanish this is called an Hacienda. A Finca (farm) does not necessarily have a mill. (And Finca is not a coffee-specific term). In a strict sense an Estate would have both a wet mill and dry mill, meaning they prepare coffee from the tree all the way to ready-to-export green coffee in jute bags. Estate coffee is not necessarily better than any other type, except that they have the possibility of controlling quality all through the process.
