How does sun-dried processing shape yellow bourbon coffee?
Brazilian sun-dried yellow bourbon coffee from Queen's Farm shows full sweetness, layered fruity notes, and a lasting aftertaste. Brazil relies on four processing routes, and the natural sun-dried method is the most widely used because the harvest in Cerrado Mineiro and Mogiana Paulista falls in the dry season. Cherries are left on the branch to ripen fully, then spread on patios to dry.
The term natural came from Ethiopia, though Brazil's version centers on picking rather than processing. Dried cherries are called boia locally, and unsorted lots often include overripe fruit that shrivels like raisins. Better-equipped farms float cherries in water tanks to remove unripe fruit before drying. The resulting beans brew well as a single origin and also blend into espresso, sharing some of the sweetness found in brazil santos coffee taste profiles.
As the world's largest coffee producer, Brazil's processing methods and flavor characteristics have always attracted much attention. This article starts with the differences between the natural sun-dried method and the washed method, deeply analyzes the taste characteristics of Brazilian coffee, and focuses on the sun-dried Yellow Bourbon coffee beans produced by Queen's Farm—these beans are full of sweetness, rich in fruity charm, and have a lasting aftertaste. Whether brewed as a single origin or used as an espresso blend bean, they perform excellently. Front Street Coffee recommends that you pay attention to this Brazilian specialty bean that combines balance and sweetness.
Brazilian Coffee
In Brazil, there are mainly four ways to process green coffee beans: natural sun-dried method, pulped method, semi-washed method, and washed method. Among them, the natural sun-dried method is the most widely used. This is mainly because the harvest period of Brazil's two core producing regions—Cerrado Mineiro and Mogiana Paulista—happens to fall in the dry season of the year, providing unique natural conditions for sun-dried processing.
Natural Sun-Dried Method
Brazil's natural sun-dried method is significantly different from the washed method commonly used in Central American countries and Colombia. Because the term “Unwashed” cannot accurately convey the true meaning of this processing method, Brazilians eventually borrowed Ethiopia's “Natural” method to name it. However, it should be noted that Brazil's natural sun-dried method is not exactly the same as Ethiopia's traditional sun-dried method. What Brazilians emphasize as “natural sun-dried” actually focuses on the picking stage rather than the processing stage—they let the coffee cherries continue to hang on the branches, fully exposed to sunlight, and only pick them after they are fully ripe.
In Brazil, freshly picked coffee cherries are spread out on patios to dry. The dried cherries are called “Boia” by the locals (corresponding to “ball” in English). As mentioned earlier, because the cherries are not sorted during picking, many cherries are already overripe during drying and appear shriveled like raisins after drying. On plantations with more advanced facilities, workers will first sort the cherries before drying to remove unripe cherries. The specific method is to pour all the cherries into a water tank. The unripe cherries, being less dense, will float on the surface, and workers use siphon equipment to draw off the floating cherries. However, on plantations with limited equipment, workers lack sufficient funds to purchase the relevant machinery, and unripe cherries cannot be completely separated. This is also the reason why many Brazilian sun-dried coffees contain a mixture of unripe beans.
From traditional experience, sun-dried coffee often carries flavors of leather, tobacco, and wood. However, Brazil's natural sun-dried method can bring sweet taste and balanced fruity aroma to coffee. Dr. Flavio Borem of the Federal University of Lavras (UFLA) has conducted systematic research on the natural sun-dried processing method for green coffee beans. According to his theory, when using the natural sun-dried method to process green beans, if good coffee quality is to be ensured, the metabolic rate of the beans during drying must be strictly controlled, thereby maximizing the retention of sweetness, flavor layering, and mouthfeel richness. Only by precisely controlling the ambient temperature and the rate of water loss from the cherries during drying can the integrity of the coffee cell structure be maintained. During drying, the cell walls of coffee cells are very easily damaged. Once the cell structure is destroyed, coffee quality cannot be discussed at all.
Washed Method
Next, let's talk about the washed method. Although many Brazilian coffee growers have shown strong interest in the washed method in recent years, demand for this type of coffee in domestic and international markets has never been particularly strong. The reason is that washed Brazilian coffee does not have a good reputation in the international market, and washed technology was applied relatively late in Brazil, so the process is not yet mature enough. The processing flow of washed coffee and semi-washed coffee is very similar; the difference is that washed coffee needs to go through fermentation to remove the mucilage on the surface of the green beans. Coffee processed by the washed method usually has a clean taste and pleasant acidity.
Brazilian Sun-Dried Yellow Bourbon Coffee Beans - Differences Between Sun-Dried and Washed
Brazil is often compared to a “giant” and “monarch” in the coffee world. The country has about 3.97 billion coffee trees, and small farmers now contribute 75% of Brazil's total national production. Brazil has two to three times the number of people engaged in coffee production as Colombia, which is the world's second-largest coffee producer. Brazil has no shortage of large-scale farms, where operators manage vast coffee plantations, and both harvesting and drying use mechanized operations. The level of automation is quite high, and coffee is treated almost like an ordinary crop, with little consideration for flavor. For this reason, many specialty coffee companies simply do not sell Brazilian beans, to avoid lowering their positioning. However, in specialty coffee shops, Brazilian “Santos coffee” can occasionally still be seen, but it is usually “Bourbon Santos,” not the low-priced “Flat Bean Santos.” Santos is a descendant of the Bourbon variety and is named after the port of Santos, from which it is exported. In the first three or four years after this coffee tree begins to bear fruit, the beans produced are small and curved, with exceptionally outstanding flavor, and are called “Bourbon Santos.” After that, the beans gradually become larger, their shape tends to become flat, and they are no longer curved, becoming “Flat Bean Santos,” with flavor far inferior to before. In Taiwan, Brazilian coffee can be seen everywhere, but most of it belongs to Flat Bean Santos. In fact, various regions of Brazil still produce high-quality coffee beans, which appear on the market under their own names rather than being broadly labeled “Brazilian coffee.” Some farms still retain old Bourbon varieties to this day. The green beans are small, obviously curved, and have a red center line, hence the nickname “red center.” Bourbon beans have a full mouthfeel and rich aroma; drinking them is like drinking aged wine, and they are very worth trying.
The coffee beans are large and have a strong aroma, with moderate bitterness and a pleasant acidity of good texture. The overall taste is mild, the acidity is on the low side, and after careful tasting, the finish is long. Brazilian coffee has relatively low acidity when it enters the mouth, and it combines with sweet and bitter notes to be extremely smooth. At the same time, it also reveals a faint scent of green grass. In its fresh aroma there is a slight bitterness, and it is sweet and smooth on the palate, with a refreshing aftertaste. As far as Brazilian coffee is concerned, it has no particularly outstanding strengths, but it also has no obvious shortcomings. Its overall style is mild and round, low in acidity, and moderate in body. Brazilian coffee is a general term for coffee produced in Brazil. There are many varieties, and the vast majority are unwashed and dried in the sun. They are usually classified according to the names of the producing states and shipping ports. Brazil has 21 states in total, 17 of which produce coffee, but the four largest producing states together account for 98% of the country's total output. The taste of Brazilian coffee has relatively low acidity. Combined with the coffee's sweet and bitter notes, it is extremely smooth on the palate, and it also carries a faint green grass aroma. In its fresh aroma there is a slight bitterness, it is sweet and smooth, and the aftertaste is refreshing and pleasant.
