[Reich Manor]

El Balar is a 5-hectare farm where Kaddura is grown. It is owned by the father of three siblings: Leo,Melvin and Elian Robles, who worked on the farm with their father for many years. El Balar is located about 1500 meters above sea level in San Marco de Tarazu. The farm has rich sandy soil and can grow high-quality coffee. They have been processing their own coffee for more than 10 years and were one of the pioneers of Tarazhu's creation of a washing plant.

01 | Origin description

Costa Rican coffee plantations with fertile volcanic ash, mild and suitable temperatures, and stable and abundant rainfall are one of the reasons why coffee has become one of the main agricultural products in Costa Rica. Its coffee beans are all Arabica species. The flavor is pure, the aroma is pleasant, and it has an impeccable balance in acidity and taste.

Tarazhu producing area has the highest average latitude and excellent climate and soil conditions, which makes Tarazhu the most famous and generally recognized coffee producing area in Costa Rica. Sanshui River (Tres Rios) is a famous small producing area in Tarazhu producing area. The most famous single estate coffee in Costa Rica in the boutique coffee world is the La Minita estate in Tarazu District, which produces only 160000 pounds a year. The climatic conditions in Costa Rica are very different, completely subverting the classification of the four seasons of the year, there are only two seasons, April to December is winter, with a lot of rainfall, and from the end of December to April the following year is the dry season, also known as summer. The annual average temperature in San Jose, the capital, ranges from 15 ℃ to 26 ℃, while the temperature in the coastal areas is relatively high, with a night average temperature of 21 ℃ and a daily average temperature of 30 ℃ in the Caribbean.

Planting conditions

The coffee beans produced at the high latitudes of Costa Rica are famous in the world, full-bodied, mild in taste, but extremely sour. The coffee beans here have been carefully processed, which is why they have high quality coffee. Costa Rica's volcanic soil is very fertile and well drained, especially in the central plateau CentralPlateau, where the soil consists of successive layers of ash and dust. Costa Rican coffee has full particles, ideal acidity and unique strong flavor.

02 | processing method

[double washing]

First washing and fermentation

After the coffee cherry harvest, the beans will first be picked by the specific gravity of the water flow; the principle is that the coffee fruit itself is screened by the difference in density and quality; the coffee beans with high density (heavy weight) will sink into the water, while the coffee beans with low density will float. The coffee fruits with high mature quality have high density, so they are screened out for further treatment.

After the high-quality and ripe fruits are selected, the peel is removed, washed and soaked, and the pectin mucus attached to the outer layer of raw beans is fermented. Pectin has natural sugars and alcohols, which play an important role in the development of sweetness, acidity and overall flavor of coffee.

The fermentation time is as long as 24 hours, and after fermentation, 80% of the pectin is removed, leaving only the flavor in the coffee beans.

The second washing and fermentation

Then enter the second washing fermentation process. After the coffee beans in the previous stage are cleaned, they are soaked in water again for 24 hours. This process increases proteins and amino acids, and the acidity of coffee beans creates complex and delicate layers of taste.

Finally, remove all the remaining pectin and move the coffee beans to a high scaffolding for sun drying, depending on the weather, which usually takes about 10 days.

03 | Analysis of raw beans

[Costa Rica double washing]

Variety: Kaddura

Kaddura's taste is full of fruit, sour berries, a little spiny, the finish is full of blueberries, raw beans look hard green, this is the most important feature of Kaddura.

04 | Baking analysis

This coffee has medium granule size, medium density and low water content. The goal of baking is shallow and medium baked, unlike other Costa Rican honey-treated beans, this Costa Rican double washing will not have the fruit fermentation flavor brought by honey treatment, and there should be a great improvement in cleanliness, so shallow and medium baking is used to show the bright acidity of the beans on the one hand and keep the taste clean and heavy on the other.

In the first batch of baking, the lower bean temperature is relatively high, the bean temperature is 200 degrees, and the firepower is also relatively high. In the baking process, it was found that although the altitude of the bean was not high, the bean quality was hard and the dehydration time was short, so the baking technique of gradually lowering the fire and climbing steadily was adopted. the firepower was fine when the beans entered the yellowing point, the dehydration was completed, and the precursors of an explosion were adjusted to avoid burns on the bean surface, and choose to come out before the end of an explosion to retain enough fruit acid.

Roaster Yangjia 600g semi-direct fire

Enter the pot at 200 degrees Celsius, adjust the firepower to 160 degrees after opening the throttle for 3, 30 seconds, keep the throttle unchanged, the temperature recovery point is 1: 38 ", keep the firepower, when 5: 20", the bean surface turns yellow, the smell of grass disappears completely, enter the dehydration stage, the firepower is reduced to 120 degrees, and the throttle is adjusted to 4.

After dehydration, the firepower dropped to 80 degrees Celsius and black markings appeared on the bean surface at 8: 30, and the smell of toast obviously changed to coffee, which can be defined as a prelude to an explosion. At this time, listen carefully to the sound of the explosion point. Start the explosion at 8: 50 ", turn the firepower down to 50 degrees, and the throttle should be fully opened 5 (the firepower should be very careful, not so small that there is no burst sound). Develop 1: 45 "after an explosion, put into the pot at 193.2 degrees."

This Costa Rican double water wash is well balanced, with the flavor of nuts, cream, sugar cane, hazelnut and melon seeds.
