The Flavor characteristics of Rosa Coffee introduction to the varieties produced by the method of Grinding and scaling

rose summer variety

The summer Geisha variety originated from Ethiopia, the birthplace of coffee. It was discovered in Ethiopia's summer forest in 1931 and sent to Kenya Coffee Research Institute. It was successively introduced to Uganda, Tanzania, Costa Rica and other countries. In 1970, it was introduced to Panama. At first, the cultivation of Rose Summer in Panama was not noticed. Because it could not reach mass production, it was also used as a windbreak forest. It was not until the owner of Emerald Manor separated it to participate in the Best Panama Competition and won the BOP champion in 2004 that Rose Summer attracted attention.

Rose summer coffee tree growth environment requirements are very high, need high altitude, cloud or shade plants, can not be directly exposed to the sun, in addition to fertile soil. The higher the altitude, the longer the ripening time and the more complex and unique the flavor of coffee fruit.

Different from other coffee varieties, the leaf system of Rosedale coffee tree is very thin, that is to say, the efficiency of photosynthesis will be very low, the root of the tree is still very fragile, the absorption of water and nutrients is very slow, so the coffee yield is very low, and the high altitude growth environment, the fruit ripening time will be relatively late. A rosewood coffee tree produces only half as much fruit as the kadura variety, which is one of the reasons rosewood is so valuable.

At present, Guixia is planted in many parts of the world and is the new king of fine coffee. Among them, Panama, Guatemala, Colombia and other Latin American countries have relatively high quality, and Panama Guixia is the best among fine coffee.

Panama rose summer

Panama is located in the southernmost part of Central America. Coffee cultivation is mainly distributed in the west, near Costa Rica and near the Pacific Ocean. Panama is roughly divided into four production areas, among which Boquete, the most famous production area in Chiriqu, Chiriquí Province, is close to Baru volcano, with fertile volcanic soil, unique microclimate in the mountains, where coffee flavor is fragrant and ripe fruit is sour and sweet, with a long aftertaste.

Emerald Manor, which we often hear about, is located in the Boquet region. It can be said that without the efforts of Emerald Manor, there would be no amazing Rose Summer Coffee today.

In 1964, Rudolf Peterson, the first Emerald Estate owner, bought an estate in Poquette that dealt primarily in dairy products. In 1973, his son Price Peterson resigned his doctorate to help his father manage the farm and introduced kadura and kaduai coffee varieties, and set up a washing plant to officially start producing coffee beans.

Emerald Manor has three estates that grow rose varieties, namely El Velo, Cannes Verdes Caas Verdes and Jaramillo Jaramillo. The best batches of rose are produced in Cannes Verdes and Jaramillo.

Emerald Manor bought Haramiyo Manor in a superior environment. Daniel, the owner of the third generation manor, found that the flavor of rose coffee beans was very unique after cup testing. Therefore, he carried out cup testing on other areas of the park and recorded the flavors of different batches of coffee beans one by one. After years of experiments, it has been found that only rose summer born at an altitude of more than 1400 meters will have a unique flavor. The Peterson family divides the plots planted according to altitude, and there are now familiar red labels, green labels and blue labels.

Among them, the red label is the special selection of jade, planted at an altitude of 1600-1800 meters, the cup score of more than 90 points rose summer coffee, but also the highest quality rose summer beans in Emerald Manor. Green label is also called private collection, planting altitude is the same as red label, because when picking mixed beans, there is no detailed label plot, so the flavor sometimes appears similar to red label flower fragrance, sweet and sour juice feeling. The blue label is the rose summer coffee planted in the environment of 1400-1500 meters. The blue label series will be cancelled in 2021. Emerald Manor will sell the rose summer coffee produced in this area for export and become volcanic rock rose summer coffee beans.

It is worth mentioning that the red label of Jade Special Selection Series has a characteristic that all coffee beans of each batch come from the same plot. For example, the red label purchased on the front street comes from the Haramiyo plot, which can provide buyers with detailed purchase options.

Of course, when it comes to high-quality rose summer, there are also many famous estates on the front street, such as Elida Manor, which has won many Best Panama competitions. Front Street also adds it to the daily production, so that everyone can taste it.

Elida Estate has a century-old history of coffee cultivation, founded by the Lamastus family in 1918, and has been handed down to the fourth generation. More than half of Elida's growing area is located in the Baru Volcano National Park, the highest in Central America. The microclimate and high-altitude planting environment brought by volcanoes allow plants to grow well. In addition to coffee, many rare fruit varieties at high altitudes are planted here.

The owner of Alida Manor has very high requirements for coffee harvesting and green bean processing. Only the coffee fruits with the highest maturity are harvested. The pectin layer has high sugar content and the flavor is complex fruit sour and sweet. This also makes Alida's Rose Summer achieve good results in many competitions.

approach

For high-quality rosewood coffee, local plantations in Panama harvest ripe coffee cherries, which are generally treated by sun and water.

exposed to sunlight

The most mature coffee cherries will be strictly screened, tiled on the terrace, try not to cover too thick, need to be manually flipped regularly, keep uniform slow drying. Due to the drying with pulp, coffee beans will have a sweet berry taste, flavor will show a more intense fruity aroma, taste more thick and full.

Anaerobic fermentation, low temperature, slow solarization

There is also a special treatment based on solarization, anaerobic fermentation low temperature slow solarization NATURAL-ASD, which is used for the summer roses produced by Arida Manor. The coffee cherries are fermented in an airtight container for 4-5 days, then spread in thick layers on a sun bed and allowed to dry slowly to enhance the coffee cherry flavor. Because ASD processing methods have to be precise and strict in controlling various details, it requires a lot of time and effort.

water washing treatment

Before drying, the coffee fruit strips off the coffee peel and pulp, and the acid produced by fermentation removes the pectin from the outer layer of the beans. The surface of the coffee beans is cleaner, and the final taste of the coffee is fresher and the acidity is brighter. The washing process requires a large amount of clean water to clean the coffee beans, so the cost of washing is also relatively high.

Brewing Reference

Having said that, how do you brew a cup of delicious rose summer coffee? Front Street considers freshly roasted coffee beans a prime condition. The aroma of coffee beans will change according to the environment and time of storage. Once the best taste period has passed, the aroma of coffee will accelerate to lose. Front Street knows how important it is to have fresh coffee, so the beans shipped are freshly roasted within 5 days, so that when we receive them, they are ready to be opened and brewed.

Front Street found that some guests think that hand-brewed coffee grinding will be more troublesome, if there is no grinding equipment, front street whether online or physical stores can provide grinding services. Since coffee beans are ground into powder, the aroma will be more volatile, so it is necessary to drink as soon as possible. If you want to drink the full flavor of coffee, Qianjie recommends equipped with grinding tools, freshly ground and brewed.

As for the grinding degree selection of hand-brewed coffee, the brewing parameters of Qianjie are based on the Chinese standard sieve No.20, and the medium and light roast coffee like Guixia will choose the sieving rate of 80%. Since the installation, use and maintenance status of each bean grinding equipment are different, even if the scale is consistent, it may lead to different coffee powder thicknesses. Qianjie suggested that if conditions permit, you can prepare a standard sun to calibrate your own grinding equipment, so that you can adjust the grinding parameters more clearly.

Front Street chose the most popular Emerald Manor red label Rosedale coffee beans. Considering that Rosedale coffee beans are lightly roasted and the solubility of coffee substances in light roasted beans is lower than that in deep roasted beans, in order to ensure that Rosedale flavor can be fully extracted, a higher water temperature is used for brewing, and a finer grinding degree is also selected.

Filter cup: V60

Water temperature: 90-91 degrees Celsius

Grindability: Sieving rate 80% on No. 20 standard sieve

Powder water ratio: 1:15

Powder: 15g

Pour coffee powder into V60 filter cup, wet the powder bed with twice the amount of coffee powder, form a drum and steam for 30s, then inject small water flow from inside to outside to 125g, and then continue to inject the same fine water flow into the third stage to 225g until all coffee liquid is filtered and removed from the filter cup, about 2 minutes.

After grinding, the red label rose summer has charming rose and citrus aromas. It tastes like berries, apricots, complex fruits and honey. It has a thick fruit juice feeling, rich flavor layers and obvious sweetness.
