Sudan Rume is generally translated as "Rumi Sultan" or "Sultan Rumi." It is a very rare coffee variety. It was not as famous as Rosedale Coffee, but it was very similar to Rosedale Coffee's experience before it became famous. Front Street Coffee to discuss what is Rumi Sultan?

The Past Life of the Sultan of Rumi

Its name gives us some clues. Similar to Rosedale coffee, it was originally grown in Africa, but not in Ethiopia, but in the Boma Plateau region of southeastern Sudan, in the Lumei Valley (now Boma National Park in South Sudan, close to the western border of Ethiopia). Hence the name Sudan Rume.

Ethiopia's western border with south sudan is a vast virgin forest containing thousands of arabica coffee varieties, while lumei sudan was only one of the unknown wild coffee species in this forest before it was known to the world. Discovered in 1942, this coffee is known in the coffee world as RS-510, essentially a wild coffee variety collected for experimentation. It has been used as the male parent of coffee hybrids for more than 50 years. When mixed with RS-510, a variety with good flavor and good yield can usually be obtained, because RS-510 has excellent flavor, but ordinary disease resistance and low yield. Mixing RS-510 with better coffee varieties allows coffee farmers to have new hybrids with high yields, strong disease resistance, and excellent flavor varieties, and many well-known modern varieties, such as Castillo, Colombia, have been developed using this technique.

The Life of the Sultan of Rumi

What made RS-510 famous as Rumi Sultan was Australian barista Sasa's 2015 World Barista Championship title with Rumi Sultan from LasNubes Estate in Colombia. What's interesting is that the batch Sasa uses is the first harvest of Las Nubes estate. You can see how good this coffee is.

However, the disadvantages of Lumei Sultan are also obvious, its disease resistance is very poor (except coffee berry disease resistance), and the yield per plant is lower than that of iron pickup. The management level of ordinary smallholder farming is not well managed. So all the Lumei Sultan beans available today are on plantations in Central and South America.

The Rumi Sultan of Front Street comes from Coffea diversa Garden in Costa Rica, which also has a nickname "Thousand Coffee Manor". Unlike most coffee farms, Diviza Manor is operating as a coffee garden. The estate is home to many local and even exotic rare varieties and varieties. It is worth mentioning that most of the varieties grown here are not found anywhere else in the world, and this is the only place where rare varieties are grown commercially.

Therefore, the species Lumei Sultan is also a coffee carefully cultivated by the owner of the estate, Gonzalo Hernandez. The biological characteristics of Lumei Sultan are dark green broad leaves, medium branch spacing, medium branch spacing, and small and long beans.
