Introduction:Brazil is one of the world’s top coffee-producing countries, and the South Minas region, with its diverse processing methods, produces many high-quality specialty coffee beans. This article delves into the region’s commonly used pulped natural processing method, exploring its processing characteristics, flavor profile, as well as the traits of common varieties like Santos and Bourbon. We also provide practical pour over grind size recommendations to help you better appreciate the charm of this classic coffee bean.
As a major player in the global coffee landscape, Brazil not only boasts high production volumes but also offers a rich diversity of processing techniques, second only to Ethiopia, the birthplace of coffee. Among these, the South Minas region in Minas Gerais state adopts a strategy that combines multiple processing methods such as pulped natural, natural, and washed, thanks to its moderate climate conditions. This has made it one of the key regions for specialty coffee production in Brazil. This article will focus on the commonly used pulped natural processing method in the area, discussing its processing principles and flavor characteristics, analyzing the traits of major local varieties like Santos and Bourbon, and finally offering pour over brewing suggestions along with grind size references to help you gain a more comprehensive understanding of this classic coffee bean.
Brazil is located on a tropical plateau with a relatively dry climate, so local research institutions have specifically developed a pulped natural process that shortens processing time to suit this environment. This method typically involves removing the outer fruit pulp from the coffee cherries, then placing the beans with their mucilage layer in the sun to dry for about one to three days. Afterward, they are moved to mechanical equipment for further drying until the moisture content drops to around 12%, at which point they can be stored. Compared to the traditional natural process, which takes two to three weeks, the pulped natural method significantly shortens the production cycle. This not only reduces the risk of the beans absorbing external off-flavors but also results in more stable overall quality. More importantly, this method successfully retains the sweetness and fruity aroma unique to the natural process while avoiding the common earthy taste, resulting in a cleaner flavor profile—especially suitable for single-origin coffee brewing. As a result, it has gradually become the mainstream processing method for specialty coffee in Brazil.
Due to microclimatic variations across different regions, various producing areas in Brazil choose the most suitable processing methods based on local conditions. For example, the Cerrado region in central-western Minas, characterized by dry air and low humidity, still primarily uses the traditional natural process. Local producers believe that, when properly controlled, the natural process best highlights the distinctive nutty aroma and rich sweetness of Cerrado coffee, whereas the pulped natural method is less commonly used. In contrast, South Minas, with its slightly different terrain and climate, demonstrates greater processing flexibility. The coexistence of the common pulped natural, natural, and washed methods allows for a more diverse flavor expression in the region’s coffee—an important reason why it has become a core part of Brazil’s specialty coffee production.
It’s worth mentioning that the diversity of coffee processing methods in Brazil is rare even on a global scale and is on par with Ethiopia, the birthplace of coffee. In addition to pulped natural, some farms also experiment with emerging processes like honey processing, continuously exploring methods that fully showcase regional characteristics. This adaptive and flexible strategy enables Brazilian coffee to not only maintain high production volumes but also secure a solid position in the specialty market.
In the annual Brazil “Cup of Excellence” national treasure bean auctions, farms from the South Minas region have consistently achieved outstanding results and are important representatives of Brazilian specialty coffee. In comparison, the Chapada de Minas region in north-central Minas, though not a specialty coffee-producing area, has massive output mainly for commercial use. Overall, South Minas, the highland areas of central-western Minas (i.e., Cerrado), and the higher-altitude forested areas in the southeastern part of the state are generally regarded as the main specialty coffee-producing regions within Minas Gerais.
When talking about Brazilian coffee, one cannot overlook the Santos variety. This variety is a descendant of the Bourbon variety and got its name because it was primarily exported through the port of Santos in the early days. Interestingly, coffee beans produced by Santos coffee trees in the early stages of fruiting (roughly three to four years) are smaller in size and slightly curved. The coffee produced during this period is called “Bourbon Santos,” which not only has standout flavors but is also highly favored by coffee enthusiasts. However, as the trees age, the beans gradually become larger, the shape becomes flatter, and the curved characteristic fades. At this stage, it is referred to as “Flat Bean Santos,” and its flavor is usually not as vibrant as in the earlier stages. Currently, the vast majority of Brazilian coffee circulating in the Taiwanese market is Flat Bean Santos—stable in quality but with a relatively simpler flavor profile.
In fact, many farms across Brazil still persist in planting traditional varieties, such as the preserved old Bourbon types. These beans have distinct physical characteristics: smaller in size, curved in shape, and featuring a faint red hue along the center line, hence referred to as “red center.” This type of Bourbon coffee delivers a full-bodied mouthfeel and intense aroma, often described as having the depth of aged fine wine—definitely worth a try for coffee enthusiasts. If you’re looking to experience a different flavor profile of Brazilian coffee, consider trying specialty coffee beans from the South Minas region made from the Bourbon variety and processed using the pulped natural method. Pair it with an appropriate grind size (for pour over, we recommend a medium-coarse to coarse grind, around 800–1000 microns), and you might just be pleasantly surprised.
