Rose Valley of Qianjie Coffee has always been a very special coffee bean. It has amazing peach plate features with aromas of cranberries, chocolate and roses. So what kind of growing environment created his unique aroma?

"good mountain and water planting environment and nutritious volcanic soil."

One is the planting environment of good mountains and good water in the Santander region of Colombia, which is about 1400-1600 meters above sea level, coupled with the coffee variety planted-Kaddura itself has a bright, clean taste and obvious sweet flavor, which creates the delicate berry acidity and caramel-like sweetness of this coffee bean.

Such a good flavor is inseparable from the resurrection of a mountain in the province of Whelan in southern Colombia in 2008, spewing out a lot of mud and ash, but fortunately not magma.

Instead of worrying, local coffee farmers hope that the mud will keep spewing out, covering the soil of the entire Columbia area with a layer of mineral-rich volcanic ash to nourish the coffee fields.

The formation of coffee flavor is closely related to the number of plant roots and the nutrition in the soil. As a result, volcanic soil has given coffee trees more flavor and aroma, and even some coffee farmers have attributed volcanic ash to the improvement in the quality of Colombian coffee after 2008 and its frequent championships.

"the post-processing method gives Rose Valley a unique flavor, not essence."

After 2014, the post-processing method of coffee has entered the fourth wave of trend; the first three waves of coffee are popular in the sun, water washing (water, anhydrous fermentation), degumming machine semi-washing, peeling and sun drying, honey treatment, except that the aqueous fermentation is in a low oxygen environment, the rest are carried out in an aerobic environment.

The anaerobic fermentation of coffee is more time-consuming and time-consuming than traditional aerobic fermentation, and the anaerobic flavor produced by yeast and lactic acid bacteria can better highlight the aroma and taste of the ensemble of lactic acid, alcohol, aldehydes and ester metabolites. just like lactic acid drinks, yogurt, the rhythm of sweet and sour fruit and thick coffee body, the coffee market, which is quite good for innovation and change, has become the fourth wave of the most representative post-production method.

Qianjie Coffee Rose Valley coffee beans are washed with anaerobic enzymes. Enzyme is actually a protein secreted by yeast, so it belongs to natural and artificial flavoring materials.

Anaerobic enzyme washing removes defective coffee beans by washing. Finally, the processed coffee beans are put into a closed container and injected with carbon dioxide to exhaust oxygen, which slows down the decomposition rate of sugar in coffee pectin in an oxygen-free environment. PH also decreases more slowly, prolonging fermentation time, so as to develop a better sweetness and more balanced flavor of coffee.

How does Rose Valley Coffee taste good?

In order to keep the unique sour aroma of Rose Valley coffee, the whole coffee can be more mellow and plump, Qianjie coffee is roasted moderately, and the substance of coffee beans can be released more easily. Therefore, when brewing, it is recommended to grind the coffee beans to a medium thickness / granulated sugar size (75% of China's 20 standard sieve), with a water temperature of 90 degrees Celsius.

Qianjie coffee shop brewing parameters: V60 filter cup, 90 degrees Celsius water temperature, moderate, 1:15 powder water ratio, powder quantity: 15g, three-stage extraction
