Introduction to the Variety characteristics of Rosa / Geisha GEISHA Coffee the relationship between the producing grade of Rosa coffee bean and its flavor and taste

Qianjie has been described in many articles that as a crop, like other fruits and vegetables, the flavor of coffee is always closely related to variety, climate, altitude, soil, management and so on. However, few coffee will be like Rosa, whose debut is the pinnacle, and it is the perfect natural embodiment of the variety when it meets the matching soil.

Get to know the variety GEISHA first.

Rosa seedlings were first found in wild forests in southwestern Ethiopia in search of new disease-resistant varieties, named after the nearby Geisha Mountains. It was taken to Costa Rica in 1954 and recorded as T2722. The subjects were planted on many coffee farms in Central and South America in the 1950s and 1960s, but were not widely planted because of their low yield and fragile plants. It was not until 2003 that it was unearthed by the Peterson family of the Emerald Manor and won the best Panama competition in 2004, which began the era of the summer of Panama.

Rose summer is very picky about the growing environment, requiring high altitude, fertile soil, clouds or plant shade, can not be directly exposed to the sun. The owner of the emerald manor said that the garden needs a large number of shade trees to block the sun for the delicate rosy summer, and traditional pruning should be used at the initial stage of planting, otherwise the plant is easy to die. The higher the altitude is, the longer the ripening time of coffee fruit is, and the more complex and unique flavor performance is.

Unlike other coffee varieties, the foliar system of Rosa coffee tree is very thin, that is to say, the efficiency of photosynthesis is very low, the root is still very fragile, and the absorption of water and nutrients is very slow, so the yield of coffee is very low. coupled with the high altitude growth environment, the fruit ripens later. The fruit yield of a rose summer coffee tree is only half that of the Kaddura variety, which is one of the reasons why rose summer is so valuable.

Since Rose Xia became famous, coffee farmers all over the world have competed to grow this variety, not only in Central and South America. However, each producing area has its own unique style, and different customs will affect the quality and flavor of coffee, so Rosa also shows its own flavor and tonality. Qianjie believes that the most representative place is the birthplace of Rose Summer-Ethiopia and Panama, the famous place of Rose Summer.

What are the flavor characteristics of rose summer in different producing areas?

Panama has only three main coffee producing areas: Boquete, Volcan and Renacimiento, but it produces the most expensive coffee in the world. Pokuit producing area is one of the towns in Chiriki province, located on the eastern side of Mount Baru at an altitude of about 1000-2000 meters, facing the warm and humid Caribbean monsoon and the cold Atlantic current on the back, with high and steep mountains. Among them, "Baru Volcano National Park" (VolcanBaru National Park) is an ecological conservation area, rich in biodiversity, with seven kinds of micro-climate, coupled with year-round mist and abundant rainfall, creating good local planting conditions. The rosy summer coffee of the Panamanian Emerald Manor and Arida Manor on the front street comes from the Pokuit producing area.

After winning the championship, Peterson and his brother managed the rosy summer coffee trees in the park more systematically based on altitude, region and cup test performance. The area planted in Rosa rugosa is divided into three plots: Cannes Vidis Caas Verdes, Haramillo Jaramillo and veil El Velo. In order to ensure the traceability of each coffee batch, Peterson refines each large plot into different small plots, through which buyers of Rose Summer Coffee can access specific planting plot information. The rose summer seed was first found in the Haramillo plot, where the Daniels decided to increase the planting elevation of the rose summer. As the discovery and cultivation land of the rose summer, Haramillo has become the most famous plot of the Jade Manor. The average elevation of Haramiyo is more than 1650 meters above sea level, and the damp and cold air in the mountains makes the rose summer coffee here full of natural essence. The emerald red sign on the front street is the Mario (Mario) plot from Haramillo, which is treated by the sun to show the fragrance of rose, citrus, berries and honey.

Back to the birthplace of the rose variety, Ethiopia is generally planted at an altitude of 1900 to 2000 meters, and ultra-high altitude is more conducive to the accumulation of sugar in coffee fruits. Qianjie believes that compared with the rose summer in Panama, Ethiopia's rose summer is mainly based on yellow drupe flavor, reminiscent of yellow peach, with medium-to-high sweetness, better batch performance and even toffee flavor.

Ethiopia's most representative rose summer coffee comes from the estate of Rosa Village, where the rose summer varieties are different from Barnabas, where there are three rose summer varieties: Gori Gesha, Rosa 1931 and IIIubabor Forest. Gori Rosa and Rosa 1931 is related to the Panamanian Rosa variety, but it is still not the same variety. The characteristics of Rosa 1931 are very similar to those of Panamanian Rosa, while Yilu Babo is a disease-resistant variety provided by Ethiopian Research Institute. In order to ensure the quality of Rosa coffee produced by Rose Village Manor, Adam, the owner of the manor, established a strict grading system, dividing Rosa into different grades, including competitive bidding, gold bid, red bid, green bid and CHAKA.

The bidding lot of Ruoxia Village is the top lot, which can only be obtained through the buyer's auction. The red mark of Rose Xia Village, which started on Qianjie Street, also has complete traceability information, accounting for 15% of the total annual output, and high-quality Rosa coffee with a score of more than 88 points according to the SCA standard cup. The Rose Summer Village Red Standard in the sun not only has the unique compound fruit, honey and flower aroma of the classic Rose Summer, but also adds the bright acidity of African coffee. Qianjie believes that this is a very cost-effective batch of Rose Summer, which is worth starting with Rose Xia enthusiasts.

How to cook the flavor characteristics of rose summer?

In Qianjie, there are many choices for rose summer alone. Here, Qianjie selects two most popular sunburn emerald red standard rose summer coffee and sun rose summer village red standard rose summer coffee, using the daily parameters of the store. Tell us about Qianjie extraction ideas!

The flavor description of each coffee on the front street is based on freshly roasted beans. If the beans have been stored for more than a month, the aroma is likely to have been lost and it is difficult to restore when brewed. Qianjie is also well aware of the importance of freshness, so it will ensure that only coffee beans freshly roasted within 5 days are shipped, so that everyone can enjoy the most complete taste period when they receive it.

The flavor of Rosa Coffee is famous for its rich floral aromas and complex fruit flavors. Qianjie roasters want to retain more high quality acidity, so they choose medium-to-light roasting (slight adjustments will be made in different batches). This baking degree does not change the high hardness of beans at high altitude, so it is necessary to improve the extraction rate in cooking to show a fuller flavor level. Higher water temperature and finer grinding will be used here to stimulate more aromatic substances, and Qianjie hopes that the flavor of Rose Summer Coffee will be clearer, so it will increase the proportion of powder to water at 1:16.

In order to improve the extraction rate of Rosa coffee and avoid over-extraction while highlighting the sweet and sour flavor, Qianjie baristas will use V60 filter cups. The body of the V60 filter cup has a diversion rib connecting the top and bottom and a large round hole in the center to accelerate the falling speed of the water flow, while the spirally shaped exhaust trough is designed to lengthen the flow path and increase the contact time of coffee powder and hot water. Each flow of water converges along the groove to the center of the filter cup, the pressure on the coffee powder is concentrated, and the extracted coffee is more layered.

The following front street demonstration store produces emerald red standard sun roses summer cooking steps, you can refer to and compare their own cooking ideas.

The parameters of red standard rose summer coffee are: filter cup: V60, water temperature: 91-92 degrees Celsius, powder content: 15g, powder-water ratio: 1:16, grindness: fine sugar size (20 sieve bowl sieve powder to 80%)

Three-stage extraction: first pour 15g coffee powder into the filter cup to clear the weight, the first stage is injected with 30g water for steaming for 30 seconds, at the same time, the whole small water flow center injection begins to circle outward, pay attention to the need to moisten the whole powder layer.

In the second stage, 120g of water is injected with a larger flow of water, in order to raise the entire powder layer, and the water column needs to be injected vertically and evenly, and the chronograph shows 150g, which is finished in about 55 seconds.

When the liquid level drops to half of the position, start to use a small flow around the small circle to inject 90 grams of the third section, try to control the flow is too large, easy to break the coffee powder layer and cause insufficient extraction. The final amount of water injection is 240 grams, and the completion time of drip filtration is about 2 minutes and 10 seconds. After removing the filter cup, shake the coffee liquid in the sharing pot and start tasting.

The hand-made jadeite red standard rose summer coffee tastes with fresh acidity of jasmine, citrus and tropical fruits, the flavor level varies with the temperature, the overall taste is smooth, and the aftertaste is pleasant.

Rose summer tastes like tropical fruit, bergamot and lemon, cream is sweet and mixed with fermentation flavor, the temperature is slightly cool, and the fragrance of jasmine slowly unfolds.
