Today, FrontStreet Coffee wants to share one of the oldest coffee varieties—Bourbon—from the renowned Brazilian estate that has won multiple COE awards, Fazenda Rainha. Brazil is a representative country for cultivating Bourbon, and the most famous type there is Yellow Bourbon, a genetic mutation of Bourbon. A recessive gene affects the color of the fruit, which turns yellow when ripe—hence the name Yellow Bourbon. The best-known Yellow Bourbon comes from Fazenda Rainha, in the mountainous border region between São Paulo state and Minas Gerais state, at an altitude of 1,200–1,400 meters. The area has abundant annual rainfall and an altitude advantage, and mature cherries are all harvested by hand. Fazenda Rainha also won second place in Brazil's COE competition in 2000, which helped establish the international reputation of the Yellow Bourbon variety.

Estate Introduction

This FrontStreet Coffee Brazil Fazenda Rainha Yellow Bourbon comes from Fazenda Rainha, a 280-acre estate located in the ancient volcanic valley of Vale da Grama in Brazil. In 2011, the estate won first place in Brazil's COE competition. Fazenda Rainha belongs to the renowned and respected Carvalho Dias coffee family. The family's four major estates have won awards every year since the first Brazil COE competition in 1999, with over 12 awards in 7 years. In 2004 they even swept the championship, 9th place, 11th place, and more. Many estates large and small in Brazil have hoped for years just to be shortlisted, yet this family's estates have won multiple awards year after year. Even Fazenda Rainha, which FrontStreet Coffee purchased, has an impressive record: 2nd place in 2000, 3rd place in 2001, and 29th place in 2005, among other results.

The Carvalho Dias family is also a founding member of the Brazilian Specialty Coffee Association, and their commitment to coffee quality and environmental protection is evident. On their family farms, they harness natural waterfalls to develop pollution-free hydroelectric power, making them self-sufficient in electricity (another award-winning estate in the family is named after this waterfall—Waterfall Estate). They have built churches, classrooms, nurseries, and medical stations, insist on preserving original forest with native flora and fauna, and continue reforestation efforts. Fazenda Rainha is a case in point: due to the higher altitude and non-plain terrain, machines cannot be used for harvesting, so all fruit is picked entirely by hand. They also cultivate low-yield, high-quality Bourbon varieties, making it a representative estate of premium Brazilian coffee.

Fazenda Rainha's Coffee Processing System

Mature cherries are hand-picked into cloth bags to avoid contact with the ground. Coffee harvested on the same day is always sent to the estate's processing facility for Pulped Natural processing that same day. Hand-picking into cloth bags avoids earthy flavors and any improper fermentation. When the harvested coffee arrives at the facility, it immediately undergoes "washing": the fruit is washed clean, and unqualified or dried fruits (bóia beans) are filtered out by size. The qualified beans that pass screening go on to the depulping process (using a pulper machine). The estate has 200 acres of Yellow Bourbon trees. The rolling mountainous terrain prevents large-scale mechanical harvesting, so all the coffee here must be picked by hand.

The estate uses semi-washed processing, followed by drying on racks and mechanical roasting. After mechanical screening, manual screening is also required. The sheer volume of work requires farm employees to live on the farm year-round. All employees and their families enjoy housing, healthcare, and education benefits here. The estate is a member of a mid-sized farm organization in the local Grama Valley, mainly exporting Bourbon specialty coffee. The organization's office is in nearby Pocos de Caldas, and it also operates a national cupping laboratory equipped with large warehouses. The organization cooperates with local universities and other institutions for research, including Lavras University—the famous Dr. Flavio Borem comes from this university's agricultural research center.

Variety

This FrontStreet Coffee Brazil Fazenda Rainha bean is 100% Yellow Bourbon, whose origin can be traced back to Bourbon's birthplace, Reunion Island in Madagascar. In the 18th century French explorers first brought coffee there, so the variety is also known as "French Missionary." In the 20th century it was brought to the African continent and then introduced to Brazil, and its derived varieties are now spread throughout Africa and the Americas. The Bourbon grown in Brazil produces yellow fruit due to the influence of recessive genes.

This bean uses the Cereza descascada method (pulped method) invented in Brazil. This natural processing method, similar to honey processing, makes the coffee flavor more rounded, with effects between washed and full natural processing. During processing, a small amount of water is first used to remove pulp and skin, then the coffee is placed directly on drying racks for sun-drying, with constant turning so all the coffee contacts sunlight. After several days of drying, mechanical drying brings it to the appropriate moisture content.

The processed beans have relatively stable properties and can be stored for a long time. They have lower moisture content, and the beans are relatively large, with 98% reaching 16 mesh or above and half reaching 18 mesh.

FrontStreet Coffee Fazenda Rainha Roasting Analysis (550g batch size)

The green beans have a solid texture and excellent flavor performance, with slight orange peel and spice aromas. Their moisture content is relatively low at 9.9%, which gives them a strong heat-absorption capacity. The roasting plan is therefore to start at 200°C, then use high heat and low airflow to speed up dehydration. After the dehydration stage ends, open medium airflow and medium heat for the Maillard reaction, not rushing the time, and finish near the end of first crack.

After 4 trial roasts, the final choice was between 1 minute 45 seconds and 2 minutes after the end of first crack. The flavor has obvious sweetness—but not a boring kind of sweetness. There is a light lemon aroma in the background, more prominent in the wet aroma stage. The later stage shows obvious dark chocolate flavor. The overall impression is quite rounded: while expressing the character of FrontStreet Coffee's Brazil coffee, it keeps a lively edge.

FrontStreet Coffee Recommendation

Fazenda Rainha's Yellow Bourbon is a benchmark for the sweet, balanced Brazilian style, and FrontStreet's other Brazilian beans carry that same character. The Brazil Cerrado Red Bourbon is a classic half-sun-dried single origin: medium-roasted, it shows creamy peanut, toasted bread, caramel, and hazelnut aromas with a rounded, low-acid body and a light bitterness, and it works for pour-over, moka pot, espresso, siphon, and French press.

For an even sweeter, fruitier cup, FrontStreet's Brazil Queen Estate Yellow Bourbon, from Mogiana near South Minas, brings a distinctive sugarcane sweetness along with fruit and chocolate notes. Brazilian beans also form the base of FrontStreet's espresso blends—the Classic Blend, the nutty Premium Blend, the balanced Black Cocoa Blend, and the shop-focused Commercial Blend—where they contribute creamy, chocolatey aromas and a soft, stable balance.
