Introduction:Want to understand the roasting essence and flavor potential of Brazilian coffee? This article takes the Yellow Bourbon from Fazenda Rainha as an example, delving into everything from regional characteristics, refined natural sun-drying processing, to optimal roast levels and pour over brewing parameters. It helps you grasp the flavor profile and brewing tips of this classic bean, offering practical insights for both beginners and advanced enthusiasts.

The roasting curve is a core element in shaping a coffee’s flavor profile. Even the same coffee bean can show vastly different acidity-sweetness balance, aroma layers, and body texture under light, medium, or dark roasting. As the world’s largest coffee producer, Brazil is known for beans that are generally full-bodied, low in acidity, smooth on the palate, and distinctly nutty and chocolatey—making them ideal for those who prefer a rich cup. This piece focuses on the Yellow Bourbon variety grown at Fazenda Rainha in the Mogiana region of Brazil, taking you through the region’s environment, varietal genetics, processing methods, as well as actual roasting curves and pour over settings, to give you a comprehensive understanding of Brazilian coffee’s flavor logic and practical applications.

The typical characteristics of Brazilian coffee include mild acidity, a full body, and often notes of caramel, nuts, and dark chocolate. These traits make it a key base for many espresso blends. As the world’s top coffee producer, Brazil has approximately 3.97 billion coffee trees, with over 75% of production coming from small-scale family farms. Moreover, the number of people involved in coffee cultivation in Brazil is 2 to 3 times that of Colombia, highlighting its pivotal role in the industry.

Since most coffee farms are located in low-altitude and flat areas, Brazilian estate owners began cultivating improved Arabica varieties adapted to plains environments decades ago. These tree varieties do not require high altitudes or shade and can be directly planted in sunny grasslands or flatlands, significantly improving planting efficiency and yield stability. This has also given Brazilian coffee its unique “plains flavor” profile.

Due to geographical and climatic conditions, Brazilian coffee generally exhibits soft and understated acidity. However, its rich notes of nuts, caramel, and chocolate, along with a solid body, still deliver a highly satisfying drinking experience. While some coffee enthusiasts find its acidity relatively muted, selecting the right variety and processing method can still reveal remarkable detail and vibrancy. For instance, the Yellow Bourbon from Fazenda Rainha in the Mogiana region is a standout—this bean not only boasts intense nutty aromas but also offers a balanced taste suitable for various brewing methods. Whether prepared via pour over, French press, moka pot, or siphon, it showcases its distinctive charm.

Fazenda Rainha is located in the Alta Mogiana region of northern São Paulo state and is owned by the Carvalho Dias family, which manages a total of four estates. Since the first Brazilian COE competition in 1999, the family has accumulated more than 12 awards, including winning 1st, 9th, and 11th places simultaneously in 2004. Fazenda Rainha itself has also performed exceptionally well, securing 2nd place in 2000, 3rd place in 2001, and 29th place in 2005—totaling three awards to date, making it a highly representative specialty coffee producer in the region.

The Grama Valley area where Fazenda Rainha is located is home to several medium-sized farms specializing in the Bourbon variety. This group operates a national-level cupping lab and large storage facilities, and collaborates with academic institutions such as the University of Lavras to advance research in cultivation and processing techniques. Notably, Dr. Flavio Borem from the university’s agricultural research center provides strong academic support for the region’s technological upgrades.

Yellow Bourbon is a mutation of the Bourbon variety. Due to recessive genes, its cherries turn a distinct yellow when ripe. This variety naturally has higher sugar content and a clean flavor profile. When processed via natural or semi-natural methods, its acidity is slightly reduced, but it achieves an excellent balance with rich sweetness and features tropical fruit aroma characteristics. Nearly 280 acres of Fazenda Rainha’s planting area is dedicated to Yellow Bourbon, with about 200 acres exclusively growing this variety—showcasing the estate’s emphasis and confidence in this cultivar.

To fully realize the potential of Yellow Bourbon, Fazenda Rainha abandoned traditional large-scale natural drying methods in favor of small-batch refined sun-drying using African beds (African Bed). The process includes regular turning of the beans by dedicated personnel and strict monitoring of moisture content changes to ensure even drying of each bean. This enhances the purity and layering of the final flavor.

After receiving the Yellow Bourbon from Fazenda Rainha and conducting multiple roasting tests, we ultimately chose to finish the roast about two minutes after the first crack. At this roast level, the coffee exhibits pronounced sweetness without being overly one-dimensional. During the wet aroma stage, subtle lemon notes can be detected, while the latter part reveals a rich dark chocolate character. The overall mouthfeel is round and full, preserving the classic traits of Brazilian coffee while adding unique lively notes—making it highly suitable for drinkers who enjoy diverse flavor expressions.

[Pour Over Recommended Parameters]

Coffee dose: 15 grams
Coffee-to-water ratio: 1:15
Grind size: Medium-fine (approximately BG#6S)
Water temperature: 90°C
Filter: Hario V60

[Pour Over Steps and Techniques]
Adopt a segmented extraction method: start with a 30-second bloom using 30 grams of water, then pour in a small circular motion until reaching 125 grams for the first pour. Once the water level drops and is about to expose the coffee bed, continue pouring to 225 grams and stop. Wait for the water level to drop again and just before it exposes the bed, remove the filter. The total extraction time is controlled around 2 minutes, effectively highlighting the aroma and layers of the Yellow Bourbon.
