In recent years, there have been more and more innovative coffee processing methods, such as anaerobic processing,Enzyme treatment, carbon dioxide impregnation treatment and other new treatment methods have begun to break into a small world. The enzyme washing treatment method that will be introduced in this article received mixed reviews when it was first introduced. Now many years have passed, Front Street will take everyone to go back and observe what is special about this treatment method.
Innovative treatment method - anaerobic enzyme washing
This approach is consistent withTraditional washed treatmentThe difference is that traditional washing processing is done through natural fermentation, while anaerobic enzyme washing uses an anaerobic environment to add enzymes to help fermentation to achieve the desired flavor.
This processing method is most classic in Columbia Tree Manor, and one of its products, Rose Valley, was born and became a blockbuster. Vargas, the owner of Big Tree Farm, has been growing coffee at Big Tree Farm for 20 years. At Dashu Farm, only fully mature coffee berries with bright red appearance are selected for picking, and the defective floating beans are removed by washing, followed by two anaerobic fermentations and a special enzyme group for fermentation. At the same time, great attention is paid to the drying process of the coffee beans, avoiding excessive temperatures during drying and adopting a slow drying method.
Anaerobic enzyme washing removes defective coffee beans through water washing, and finally puts the processed coffee beans into a closed container, injects carbon dioxide to expel oxygen, and slows down the decomposition rate of sugar in coffee pectin in an anaerobic environment. The pH also decreases at a slower rate, prolonging the fermentation time, thereby developing a better sweetness and a more balanced flavor of the coffee.
FrontStreet Coffee (FrontStreet Coffee) Rose Valley comes from Dashu Manor. It uses anaerobic enzyme washing to use this coffee beans, which has a peach-like aroma and a light rose fragrance.

Coffee varieties
Caturra is a natural variety of Bourbon species. It was discovered on a plantation in the Brazilian state of Minas Gerais between 1915 and 1918. Bourbon grown in plantations has a set of genetic mutations that cause the plants to grow smaller (similar to dwarfism). This new coffee species expressed in a new biological form is called Caturra by the locals in Guarani, which means "small". Sometimes called "Nanico".
Caturra's petite size allows plants to be planted closer together, and its secondary branches are closely spaced, allowing it to produce more fruit in the same space. This results in a significant increase in unit output. And because of its petite size, it is easier to harvest. In Colombia, Caturra's production is considered to account for almost half of the country's production. It has both high-quality acidity and aroma, overall brightness, and good sweetness.
FrontStreet Coffee roasting analysis
Considering that Columbia Rose Valley uses a double anaerobic washing method, in order to retain the fruity notes and rich acidity of the beans while showing the cleanliness of the taste and the sweet and sour flavor, Front Street roasters use medium roasted Rose Valley coffee beans.
Yangjia 800N, amount of beans added: 480g. When the furnace temperature reaches 180 degrees Celsius, put the pot into the pot, open the damper 3, and the fire power is 130; the temperature return point is 1'36'; when the furnace temperature reaches 140 degrees, the fire door opens 4; when the furnace temperature reaches 151.6 degrees, turn to the yellow point 6'00'. At this time, the bean surface turns yellow, the grassy smell disappears completely, and it enters the dehydration stage. At 8'17' Ugly wrinkles and black spots appear on the bean surface, and the smell of toast obviously changes to the aroma of coffee, which can be defined as the prelude to the first crack. At this time, you should listen clearly to the sound of the first crack. The first crack will start at 9'48', fully open the damper, and reduce the heat to 80 at 188°C; reduce the heat to 50 when the temperature is 192 degrees; after the first crack, it will develop to 2'10' and cook at 197°C.

After the coffee extraction is complete, shake gently and wait until the coffee liquid is fully even before tasting.
Flavor description
In terms of processing method, Rose Valley uses double anaerobic enzyme washing, so the acidity is more obvious. Generally speaking, Rose Valley tastes more like a glass of juice, with a grape and strawberry flavor mixed with floral aroma.
