Mocha
Mocha is considered a dwarf variety of bourbon. It is short, produces round cherries and seeds, and is genetically very close to bourbon.
Mocha, named after Moka Port in Yemen, was planted in Yemen and brought to reunion island. Now it is cultivated all over Central America.
/kloc-In the 5th century, Mocha Port monopolized the coffee export trade, which had a great impact on the coffee export trade in Arabian Peninsula.
From15th century to the beginning of18th, almost all coffee beans produced in Africa were exported and transported to European countries through Mocha Port. Coffee exported from Mocha Port is called "Mocha Coffee".
Strictly speaking, mocha coffee beans refer to coffee beans with rich chocolate flavor. This makes people associate chocolate with coffee and develop chocolate espresso.
But in Europe, "mocha coffee" may refer to this drink, or it may just refer to coffee brewed with mocha coffee beans.
