You might want to read Antony Wilds book "Black Gold" who has a different slant on the spread of coffee throughout the West Indies. He claims that the Spanish brought coffee to Cuba in 1748.
Wild refers to Frenchman Gabriel de Clieu whom the coffee industry credits with the spread of coffee throughout the West Indies starting in Martinique in 1723. Wild claims that de Clieus story is not true as the Dutch already had introduced coffee in Surinam in 1718 and the French in Hispaniola in 1715.
Yemen is regarded as the origin of coffee arabica plants grown throughout the world as but Yemens coffee is thought to have originally come from the Harar district of Ethiopia.
This German site has some info about growing conditions for what its worth.
I cracked a bag of this yesterday, 9 days after roasting. My first mouthful was cigars, not really that nice on first impression but there was a lingering aftertaste of spice and other flavours I couldnt properly define as it was made in a latte. I will try it as an espresso tomorrow.as 9 days is till too short a rest period for my preferences of most coffee I roast.
