Yemenn Coffee is,
The only true  Mocha and The world's most  Most Exotic and Oldest Coffee.  Most famous coffees comes from Yemen (Ismaili, Matari). The coffee is Yemen Mocha, long and justly considered to be the world's greatest, uniquely delicious coffees. Once the subject of myth, Mocha coffee has become the object of Misunderstanding and misrepresentation (for the chocolate taste). Mocha coffee takes its name from  the Yemeni  port city  called Mocha, a small port in Yemen on the Red Sea. Some four centuries ago small quantities of this coffee with a very fine flavor, grown on the hillsides of Yemen, were exported through this port. It was the first coffee enjoyed by Europeans. Soon after, all imports from Arabia Flex (Yemen) were classified as Mochas. In the seventeenth and early eighteenth centuries even coffees grown in the West Indies, Indonesia, Ethiopia were marketed as Mochas. The coffee trees growing in the West Indies were at that time the grandchildren of the trees in Yemen; the beans produced in both locales were, to the taste, indistinguishable. Since place names were intended primarily as guides to flavor, the labeling was, if literally inaccurate, effectively true. Were the growths of Yemen compared today, the difference in flavors would be easily recognized. An attempt to classify these growths as Mochas in the modern marketplace would be deceptive and confusing and foolish. How did what was true become a lie? The soil, altitude, and climate of any given coffee-growing area contribute unique characteristics of body, flavor, and aroma to the beans produced in that area. It has been centuries since the Arabian seed was smuggled and transplanted to the West Indies, Indonesia, and Caribbean coffee has taken on the character of its new home. For better or worse it must live up to the merits of its new name-not the name of its ancestors.  
Yemen Mocha Coffee is cultivated and processed today much as it has been for centuries. Seedlings, grown in nurseries, are transplanted to terraced farms (from 6,000 feet to 7,500 feet), which have been carved out of the steep hillsides. Lack of rain necessitates the maintenance of irrigation systems designed to provide the trees with controlled constant moisture. The relative dryness of the soil and air results in the production of a bean that is small and extremely hard. Yemen's entire tiny crop is processed by the dry method, and much of it, in fact, is permitted to dry on the tree before picking and hulling. Again, it is the dry hot air that permits this unusual but in this case,advantageous technique. This rather primitive method of producing coffee goes back centuries and accounts for the classic flavor which this wonderful coffee displays. It's worth noting that this coffee is grown organically. It is not something the farmers set out to do, but there is probably no more primitive coffee-growing area on earth. The region is very remote, and the dried coffee must be carried out of the steep valleys by donkeys. Carrying in heavy fertilizers is beyond consideration even if it might increase yields. 

Yemen Mocha is packed in special plaited straw packages known as 'mats" rather than the bags now used universally. The appearance of the bean is as unique as its packing. These small round beans are irregular in form and size with a peculiar pale green to yellow color. But despite this (or perhaps because of it), they yield one of the finest cups of coffee on earth. The Yemen Mocha has tremendous character and wonderful complexity. It can be described as winey, spicy, nutty, malty and fruity. Its uniquely acid cup makes this coffee simultaneously smooth and piquant (pleasantly pungent). It possesses heavy body, and unique flavors a characteristic usually lacking in its nearest cousins, the Ethiopians. This coffee yields one of the most superbly aromatic and uniquely-flavorful cups in the world. We feel fortunate to be able and continue to bring this rare and delicious coffee to our customers the same way started more than 400 years ago.

Botanical varieties: 
Virtually all Yemen coffee comes from ancient, "heirloom" varieties of coffee arabica first naturalized hundreds of years ago. The two most famous are Ismaili, which produces small, round, pea-like beans, and  Mattari, which produces small, rounded, oval beans.
