Among the thousands of different coffee bean species, it is inevitable that some beans have unique names! They don't have conventional names like most beans such as Bourbon and Typica, but they have their own numbers like secret spies.

For example, bean varieties named with English letters + numbers include: Kenya's SL28, SL34; or Costa Rica's H1, or F1. But when it comes to varieties that are all numbers, the first thing that comes to mind must be the Ethiopian number series starting with 7! So the question is ~ what does this string of numbers mean?


The Origin of “Digital Beans”
Ethiopia is the birthplace of coffee, and there are tens of thousands of coffee species that have yet to be officially named. Because the quantity is really too big! The time it takes to test and verify one by one is unimaginable! Therefore, the local government decided to use "Heirloom" to collectively refer to them.

On the one hand it’s convenience, on the other hand it’s about protecting these breeds! After all, as the birthplace, coffee practitioners from various countries will naturally compete to obtain it, just like the story of "Gesha and Gesha 1931"! The number series starting with 7 is a series of beans that have been harvested from "native species" and gained new names! The origin of the story goes back to 1970...
In 1970, a coffee-specific disease spread in Ethiopia. Infected coffee berries will lose their original beautiful color, turn gray-black, and then die on the branches. This disease is named "Coffee Berry Disease" (CBD).

Once the coffee trees are infected, it will cause huge losses to the coffee farmers! As a result, coffee farmers began to use chemical drugs to prevent and combat these diseases. Although they had a certain effect, they were still spraying pesticides, treating the symptoms but not the root cause. Therefore, people still started to change their species! That is to find natural varieties with strong disease resistance.


Beginning in 1973, Ethiopia's Coffee Agricultural Research Center JARC targeted 15 areas to collect coffee beans. It continued until 1975 and collected a total of 639 samples of different coffee varieties, and then conducted scientific identification and planting experiments on them. Finally, in 1978, among these 639 samples, a total of 13 beans stood out. Not only are they resistant to CBD, they are also high-yielding, drought-tolerant, and have very good flavor!

In this way, JARC classified some beans as "1974/1975CBD-Rexistent Selections", they are: 741, 75227 in the Gera area; 74110, 74112, 74140, 74148, 74158, 74165 in the Metu-bishari area; 744, 7440, 7454, 7487 in the Washi area; and finally 754 in the Wush Wush area. The 74/75 here refers to the year of discovery, and the numbers following 74/75 are their respective numbers!


The reason why these numerically numbered bean seeds have become famous in recent years is due to Ethiopia’s Cup of Excellence, or Coe for short. Because the names of the varieties will be announced at the end of the Excellence Cup, when the list of winners was announced, people discovered that only three of the top ten were traditional Typica varieties, and the remaining seven bean names were all numerically coded! Oh, let’s just fight to become a god! “Coffee people” from all over the world are rushing to buy it, just to explore the delicious taste of the 74 series.

But at the beginning, let alone foreigners, even their own people at home didn’t know what the origin of this series was. The grower of the 74165 bean seed that won the championship did not know it was 74165 at first. However, when the association verified its plant when submitting it, it was discovered that it was the 74165 variety of that year.


So, what will these 74 Series coffees taste like? Among the beans roasted by Qian Street, there is also a numbered variety of beans, which is the Santavini coffee beans from the Sidamo production area, variety 74158. The 96-hour anaerobic sun-drying method gives this coffee beans an extremely fragrant flavor.The fragrance of flowers and fruits is sweet and sour,Below, Front Street will show you how to bring out its gorgeous flavor.

Considering that FrontStreet Coffee beans are lightly roasted and have a hard texture, high-temperature hot water of 92°C-93°C is needed to bring out the floral and fruity flavors in the coffee. Grinding Front Street recommends medium-fine grinding (Chinese standard No. 20 sieve pass rate 80%), because it is too coarse to extract the mellow sweet substances, and the brewed coffee will appear thin.In terms of brewing ratio, Front Street believes that 1:15 to 1:16 is acceptable. If you want a richer taste, use 1:15. If you want to feel the floral sweetness more clearly, you can use 1:16 to make the flavor more spread out.

Three-stage water injection: Wet the powder bed with twice the amount of coffee powder to form a drum and steam it for 30 seconds. Then inject water in a small circle from the inside to the outside until it reaches 125g. When the powder bed drops to half of the filter cup, continue to inject the same thin water flow into the third section to 225g until all the coffee liquid has been filtered and take out the filter cup, which takes about 2 minutes.



Taste the brewed 74158 coffee on Front Street Street and feel the rich layering. The entrance of the coffee is the aroma of dried mango, strawberry, and black tea. The sweetness is very prominent. As the temperature drops slightly, the orange-like juice flavor is obvious and the finish is short. Even after the coffee is completely cooled, the fruity flavor remains prominent and is almost non-bitter, making the taste bud experience very pleasant.
