How Did Arabica Reach Brazil as Red Bourbon?

Brazilian Red Bourbon is one of the oldest varieties in the Arabica family. It began on Réunion Island, then spread through Africa and Latin America via missionaries before taking root in Brazil. Bourbon shows more vitality than Typica, adapts well to its environment, and yields more, with a thick sweet-acidity and occasional floral or nutty notes in the cup.

The Cerrado South Minas region sits at roughly 700 to 1,200 meters, mostly hilly terrain, and is Brazil's earliest developed coffee area; rising labor costs mean mechanical harvesting now dominates. Bahia in the north mainly produces washed beans, while coastal Espirito Santo leads in Robusta. Following coffee seeds from farm to roast shows how variety, terroir, processing, and roasting together shape the final cup.

Brazilian Red Bourbon is one of the oldest varieties in the Arabica family. Starting from Reunion Island, it spread to Africa and Latin America through the hands of missionaries, eventually taking root in Brazil. This article systematically reviews the full picture of Red Bourbon, from variety characteristics, origin distribution, and propagation history to semi-washed processing and grading systems; and using the Cerrado South Minas region as an example, it analyzes Front Street Coffee's roasting curve and cupping performance, with specific parameters for pour-over and espresso blends, helping coffee lovers understand the charm and brewing key points of this balanced bean variety.

Front Street has always believed that a satisfying cup of coffee depends on every step from seed to cup: whether the variety is excellent, whether the growing environment is suitable, whether the farmer cultivates with care, whether harvesting and fermentation are done properly, and whether roasting is just right—these all affect the presentation of the variety's regional characteristics. As a self-roasting coffee shop, Front Street is well aware that to achieve the ideal flavor in the cup, no step can be careless. Today, using Brazilian Red Bourbon as an entry point, let's talk about why variety matters. Bourbon belongs to the ranks of the oldest varieties, with stronger vitality than Typica, good adaptability to the environment, and higher yield than Typica. The Bourbon family has many variants, including Yellow Bourbon, Red Bourbon, and Pink Bourbon. Its main flavor expression is a thick and distinct sweet-acidity, and some batches also bring out obvious floral notes or prominent nutty tones.

01|Origin Introduction

South Minas has an altitude of about 700 to 1,200 meters, mainly hilly terrain, and is the earliest developed coffee-producing region in Brazil. Due to rising labor costs, mechanical harvesting is now mostly used. This is also the earliest area of coffee commercialization, with large exporters seen everywhere. The Bahia region in northern Brazil mainly produces washed Brazilian beans, while the Espirito Santo region near the coast is Brazil's main export area for Robusta varieties. Brazil's coffee-growing terrain is roughly divided into two types: the Brazilian Plateau above 500 meters and the Brazilian Plain below 200 meters. The widely known cultivated variety is Bourbon, including Yellow Bourbon, Red Bourbon, and flat-bean Santos. Brazilian coffee as a whole shows low acidity, nutty flavors, balance, and moderate body. In the specialty coffee field, Brazilian beans are not particularly outstanding, but they often play an important role in espresso blends. Because of their high balance, they are also often used by merchants as Blue Mountain-flavor beans.

Bourbon Variety

Let's briefly explain what Bourbon coffee is. Bourbon coffee was first planted on Reunion Island, which was called le Bourbon before 1789. Bourbon is a secondary species produced by a mutation of Typica. Together with Typica, it belongs to the oldest existing coffee varieties, and the fruit is bright red when ripe. The color change process of Red Bourbon fruit is: green, slightly yellow, slightly orange, ripe red, and then darker red when more mature. Therefore, some people also call it the Red Bourbon variety, but it is actually what we usually call Bourbon. Bourbon grown at high altitude often has better aroma and brighter acidity, and can even taste somewhat like red wine. In simple terms, Bourbon is a branch under the Arabica species and generally bears red fruit, called Red Bourbon; there are also Yellow Bourbon and Orange Bourbon, among which Yellow Bourbon has relatively lower yield but often better quality.

The Propagation Route of Bourbon

The Typica variety introduced to Brazil in 1727 had low yield and was susceptible to disease, so Bourbon entered Brazil around 1860 via Campinas in the south, and then quickly spread northward to other parts of South America and Central America. In Latin America today, most Bourbon has been replaced by its variants, especially Caturra, Catuai, and Mundo Novo, but it is still grown in countries such as El Salvador, Guatemala, Costa Rica, and Peru. In Africa, French missionaries known as Spiritan (from the Congregation of the Holy Spirit) played a key role in the spread of Bourbon. In 1841 the first mission was established on Reunion, and in 1859 a branch was established in Zanzibar; starting from Zanzibar, in 1862 one branch was established in Bagamoyo (coastal Tanzania, then called Tanganyika) and one in St. Augustine (Kikuyu, Kenya), and in 1893 another branch was established in Bura (Taita Hills, Kenya). Each establishment of a mission was accompanied by the planting of coffee seeds brought from Reunion.

In 1899, seedlings cultivated at Bura were taken to another French mission in Saint Croix (near Nairobi). In 1900 they were introduced to the Kilimanjaro region of Tanzania, and the seeds were distributed to local residents willing to grow coffee. This is the origin of Missionary Bourbon. After that, the Kent variety was also introduced in 1920. Therefore, even today Tanzanian coffee is still mainly Bourbon and Kent. The propagation route is roughly: French Bourbon Island—1860 Bourbon Pointu to New Caledonia; Yemen—1732 Bourbon Round to the British territory of Saint Helena; 1860 Bourbon Round to Brazil; 1900 Bourbon Round to Rwanda, Kenya, and Tanzania; after 2000 Bourbon Pointu to Colombia.

03|Processing Method Introduction Semi-Washed Method

After coffee cherries are picked, they first pass through a water tank to remove immature fruit and foreign matter, then the skin and part of the pulp are removed, and the mucilage is removed with a demucilager. Removing mucilage can shorten the time required for sun drying and reduce the risk of fermentation. This processing method is mostly used when climatic conditions are not ideal. If air humidity is high, the climate is warm, or there is rainfall, mold damage is likely during drying. Therefore, most washed beans in Brazil used for commercial trade are processed by the semi-washed method.

02 | Green Bean Grading

Brazil has many types of coffee, and the processing method is mainly natural. They are usually classified by producing state name and shipping port. Because production areas are scattered and quality varies, classification standards are also not uniform. Brazil's grading system scores defect ratio, size, flavor, and mouthfeel, and is an independent system that is more complex than those of other countries. For example, in Brasil Santos, NY 2 SC17/18 SS FC, NY2 is the defect ratio grade; the larger the number, the more defects, in order: 2, 2/3, 3, 3/4... NY indicates that the New York grading standard is used as the basis. SC 17/18 indicates the screen size of the coffee beans. SS FC (Strictly Soft and Fine Cup) indicates flavor and mouthfeel. This classification has two groups: the first group is Strictly Soft, Soft, Softish, Hard, Hardish, Rioy/Rioysh, Rio; the second group is Fine Cup and Good Cup. The main characteristics of Brazilian coffee are high sweetness, cleanliness, smoothness, and low acidity. It has wide uses and is deeply loved by the public.

04 | FrontStreet Coffee Roasting Analysis Roaster Yangjia 600g Semi-Direct Fire

Brazilian coffee generally grows at an altitude of 1,000 to 1,300 meters, has relatively low density, moderate moisture content, softer bean texture, and a thinner distance from bean surface to core, so it is not suitable for roasting at too high a temperature, otherwise it easily develops burnt bitterness. Front Street uses medium heat when charging the beans, maintains the heat through the dehydration stage, and makes fine adjustments as the temperature rises after first crack begins, promoting a fuller caramelization reaction. This semi-washed bean rises slowly in temperature after first crack, and can be dropped near second crack. Preheat the roaster to 200°C and charge the beans, open the damper to 3, turn on the flame after 30 seconds, adjust the heat to 160, keep the damper unchanged, turning point at 1 minute 30 seconds, maintain the heat, turn yellow at 5 minutes, the grassy smell disappears, entering the dehydration stage, lower the heat to 130, open the damper to 4. At 168°C, lower the heat again to 100. At 8 minutes, dehydration is complete, the bean surface shows wrinkles and dark streaks, and the toast aroma turns into coffee aroma, which is the prelude to first crack. At this time, pay attention to listening for the sound of first crack. First crack begins at 8 minutes 50 seconds, open the damper fully to 5. After first crack, development time is 3 minutes 10 seconds. At 190°C, lower the heat to 50, at 194°C lower it again to 30, and drop the beans at about 200°C.
