Flavor characteristics of Rose Summer Coffee Story hand-brewed Flavor is the Rose Summer Price of Panamanian Jade Manor expensive

Nowadays, most of the beans selected in the major coffee competitions are Rosa Coffee. How on earth does this excellent coffee variety show? How to distinguish the grades of summer roses? Qianjie Coffee specially tried a lot of Rosa Coffee for this purpose, trying to find the rules among them.

What is Rose Summer? Rose summer refers to a variety of coffee, called "Geisha/Gesha" in English, and happens to have the same name as "Geisha" in Japanese, so some people call it a geisha.

Qianjie coffee believes that variety is an important factor affecting the overall taste of coffee, just as there are differences between green apples and snake fruits in apples, while high-altitude rose coffee is easy to have obvious floral aroma and delicate and elegant acid. such an elegant flavor is also one of the reasons why it is popular all over the world.

Where does Rose Summer come from? The variety Geisha was discovered in the forests of Ethiopia in 1931. Rosa was then sent to the Coffee Institute in Kenya, introduced to Uganda and Tanzania in 1936, Costa Rica in 1953 and Panama in 1970. At first, little attention was paid to Rose Summer, until the Panamanian Emerald Manor, also known as Panama Geisha Hacienda La Esmeralda, separated it from other varieties in 2003 and became the winner of the BOP competition in 2004. The rose summer variety officially entered everyone's line of sight. When La Esmeralda talks about Panamanian rosy summer coffee, he has to mention the famous Emerald Manor. In 1964, Rudolph Peterson, an American banker, retired, moved to Panama and bought the emerald estate in Poquet, initially dominated by dairy. Then his son Price resigned as a doctor to help his father run the farm, introduced Kaddura and Kaduai coffee beans in 1987, set up a washing plant in 1994, and has had its own coffee processing plant ever since.

At present, the Emerald Manor mainly has three manors to grow rose summer varieties: veil El Velo, Cannes Vidis Caas Verdes, Haramillo Jaramillo. Haramillo Jaramillo, which has a superior geographical environment and good flavor of the original coffee variety, was bought in 1996. Veil El Velo was acquired by Jade Manor in 2012. Qianjie Coffee believes that the acquisition of a high-altitude manor like Jade Manor was a unique decision at that time, which made it possible for the Jade Manor to occupy a certain position in the coffee industry. Among them, Haramiyo Manor is the estate that planted the Panamanian rose summer coffee bean breed. Because of its low yield, the former owner only used it as a windbreak tree, and it was not until it was acquired that it was found to be distinctive. Qianjie Coffee feels that this is the charm of Rose Summer. The worse the environment, the better the flavor. Although the Jade Manor found coffee beans with flavor at the beginning, in order to be accurate, the coffee beans in different areas of the garden were tested, and the planting plots were determined according to the elevation.

After winning the championship of BOP in the Panamanian bean competition in 2004, it was later identified by experts that the coffee bean was a rose summer variety of Ethiopia. Since then, the Peterson family has focused most of its efforts on developing infrastructure to support excellent batch separation and fine processing. Jadeite Manor Rose Summer Classification: the marketing strategy of Red Standard, Green Standard and Blue Standard Jadeite Manor is different from other manors. according to the cup test performance and the varieties and plots planted, it is divided into five brands. There are three brands of Rosa varieties: jadeite Special selection (Esmeralda Special), Private Collection (Private Collection) and Rosa 1500 (Geisha1500). Kaduai has two brands: Diamond Hill (Diamond Mountain grows) and Pamela (Palmyra). The rosy summer of the specially selected jadeite is the red mark we often hear. The rose beans, which are planted at 1600-1800 meters above sea level and with a cup test score of more than 90 points, are produced in two producing areas: Jalamiyou (Jaramillo) and Kanaus Vedvis (Caas Verdess). The independent bidding held by the Jade Manor itself, in the divided plots, the Rose Summer batch that was put forward for bidding is the red bid. However, there are also non-competitive red bids on the market, that is, the rose summer which is selected from the same plot and then circulated to the market, the varieties and quality are the same, but there are differences in the price. This grade of rose summer is treated in the sun or water, with special, bright floral and citrus aromas.

Private collection, commonly known as green standard, is not a batch of independent competitions, planting rose summer varieties that do not participate in bidding but are still of excellent quality. Micro-batch mixed beans from different plots, such as Jaramillo and Caas Verdess, were planted at 1600-1800 meters above sea level. Due to the use of mixed bean mode, there is no detailed indication on the plot, so sometimes the flavor similarity between green mark and red mark is very high, but the next production may be different. Although the green standard is not as high as the red standard, it still has the classic flavor of Rose Summer, floral, fruity, sour citrus, thick and juicy taste. In recent years, green standard rose summer provides water washing treatment and sun treatment. It is well known that the higher the altitude, the richer the aroma changes to the coffee. Rosa coffee also has a strange feature, that is, growing in the more extreme environment, the best flavor performance, people familiar with the history of this variety will know, Rosa was found in the windbreak forest because of the unique flavor. This feature is reflected in the cup test of Qianjie Coffee. Different beans of Qianjie Coffee will use different grindings to ensure that all tested samples have a pass rate of 70% in the standard sieve. In order to achieve this pass rate, we need to adjust the bean grinder to a smaller gear than other low-altitude beans, as well as in some other high-altitude beans.

Rose summer 1500 blue standard rose summer selected 1400-1500 meters above sea level, produced from three different plots: Jaramillo, Caas Verdess and El Velo. The flavor is slightly floral, sour and sweet, and the taste is not thick. Blue standard rose summer was originally only washed with water. A new version of tanning treatment was added in 2020. In these levels of jadeite, because the red mark and the green mark belong to beans at the same altitude, only the red mark specifies the plots, while the green mark is mixed harvested, the price is very different, so the view of Qianjie coffee is that the performance-to-price ratio of the green mark will be higher.

Qianjie Coffee roasting suggests that Qianjie Coffee roasts these three different grades of Panamanian rose summer coffee beans, the main idea is to highlight the rich flower aroma and bright and changeable fruit acid characteristics, using light roasting methods. However, Qianjie takes into account the different growth environment of each level, and the baking details also need to be adjusted accordingly.

The red standard rose summer furnace temperature is 150℃ into the pot, the firepower is 120mm, and the throttle is set at 3; the temperature is 1: 36 ", when the furnace temperature is 140℃, the throttle is opened to 4, the firepower remains the same; when the furnace temperature is 147.6 ℃, the bean watch turns yellow, the grass smell disappears completely, and enters the dehydration stage. When the furnace temperature reaches 150℃, the firepower is adjusted to 100, and the throttle remains unchanged. The smell of toasted bread has obviously changed to the smell of coffee, which can be defined as a prelude to an explosion. At this time, it is necessary to listen carefully to the sound of the explosion point, when the sound of the explosion point begins to explode, the throttle opens to 4, and after the explosion, the development of the ℃ after the explosion begins.

The green standard Rose summer furnace temperature 160℃, firepower 110, throttle opening 3; tempering point 1160mm 391028 ", the furnace temperature 140℃ will open the throttle to 3.5.The firepower will not change; when the furnace temperature is 153.3 ℃, the bean watch will turn yellow, the grass smell will disappear completely, and enter the dehydration stage. When the furnace temperature reaches 161℃, the firepower will be adjusted to 90 and the throttle will not change. The smell of toasted bread has obviously changed to the smell of coffee, which can be defined as a prelude to an explosion. At this time, it is necessary to listen carefully to the sound of the explosion point, when the sound of the explosion point begins to explode, the throttle opens to 4, and after the explosion, the development of the ℃ after the explosion begins.

The blue standard rose summer furnace temperature 180 ℃ into the pot, firepower 130, throttle open 3; temperature recovery point 1 temperature 39 ℃, open the throttle to 4, the firepower remains the same; when the furnace temperature is 151.6 ℃, the bean watch turns yellow, the smell of grass disappears completely, and enters the dehydration stage. The smell of toasted bread obviously changes to the smell of coffee, which can be defined as a prelude to an explosion. At this time, it is necessary to listen carefully to the sound of a burst point. The sound of the explosion point begins to explode at the 8th hour, the throttle opens to 5, and the development after the explosion begins to drop beans at 28190 ℃. Suggestion on brewing coffee in Qianjie

Qianjie recommends using freshly roasted coffee beans for brewing, so that you can maximize the rich flavor of the coffee. The coffee beans shipped in Qianjie are all roasted within 5 days, because Qianjie is well aware that the freshness of coffee beans has a great impact on the flavor. The purpose of Qianjie roasting is "freshly roasted coffee", so that every guest who places an order is the freshest coffee when he receives it. The bean cultivation period of coffee is about 4-7 days, so when the guest gets it, it is the time when the flavor is the best.

The recommended brewing parameters for Qianjie coffee are: Hario V60 filter cup, 90 ℃ water temperature, 15 g powder quantity, 1:15 powder-to-water ratio, fine grinding in use (80% pass rate of Chinese standard No. 20 sieve).

Qianjie takes into account that these rose summer coffee beans are lightly roasted, and the solubility of light roasted beans is lower than that of deep roasted beans, so in order to ensure that the flavor of rose summer can be fully extracted, higher water temperature is used for brewing. At the same time, a finer degree of grinding is also selected. Brewing technique Qianjie coffee using staged extraction, also known as three-stage brewing, steaming with 30 grams of water for 30 seconds, small water injection around the circle to 125 grams for stages, water level drop is about to expose the powder bed, continue to inject water to 225 grams to stop water injection, such as the water level drop is about to expose the powder bed to remove the filter cup, (steaming starts timing) the extraction time is 2 grams 3900 ".

Rose summer coffee flavor description red standard: there are bright roses, citrus aroma, black rice, berries, apricots, compound fruits, honey, thick juice, rich flavor levels, sweet obvious. Green label: strong jasmine fragrance, high sweetness, citrus, berries, juice, cream, green tea, orange peel, cantaloupe, the overall flavor is rich, aftertaste, citrus lasting.
