How does the coffee bean process shape Pink Bourbon flavor?

Colombian Pink Bourbon is a rare variety grown in southern specialty regions such as Huila and Cauca, prized for pink cherries and delicate berry notes. The coffee bean process used after harvest, whether washed, semi-washed, or anaerobic washed, decides how much of that fruit acidity survives into the cup. Beans are grown mostly above 1,500 meters and picked selectively.

Huila coffee from the San Agustin area represents the classic Colombian profile of nuts, chocolate, and high sweetness, which is why it often forms the base of espresso blends. Pink Bourbon takes a different route, leaning toward refined berry acidity, so it is handled carefully to preserve clarity. Roast level and brewing parameters then determine whether those fruit notes read as bright or muted.

Colombia is not only the world's third-largest coffee exporter but also home to numerous specialty regions, from Huila to Cauca. Beyond common varieties like Caturra and Bourbon, Pink Bourbon stands out with its romantic pink cherries and delicate berry notes. This article starts from the Front Street Coffee daily bean series to outline Colombia's coffee region distribution, variety characteristics, and three processing methods—washed, semi-washed, and anaerobic washed—and provides detailed information on three Front Street Pink Bourbon coffees, including origin details, flavor descriptions, roasting analysis, and brewing parameters, offering a complete reference for coffee enthusiasts.

Among Front Street Coffee's daily bean lineup, Front Street Colombia Huila coffee beans are a representative of classic Colombian flavor—rich aromas of nuts and chocolate intertwined, with excellent sweetness. Because of this rich, full-bodied character, Front Street Colombia coffee beans are also often chosen as a base for espresso blends. Several of Front Street Coffee's own roasted espresso blends contain Colombian beans, which produce a balanced and satisfying cup when used for espresso or other coffee drinks. However, Colombia also has a Front Street Pink Bourbon coffee that takes the route of refined berry acidity. Although it is not a typical flavor of the Colombian region, the variety's rarity and pleasant flavor profile make it a high-quality bean not to be missed.

Front Street Colombia Coffee

Colombia is located in northwestern South America, adjacent to Panama in Central America. In 1808, a priest brought coffee into Colombia for the first time from the French Antilles by way of Venezuela. Today, Colombia is the world's third-largest coffee exporter, mainly focused on Arabica beans, and is also the country that exports the most Arabica coffee beans. This land is rich in resources, with coffee, flowers, gold, and emeralds known together as the "four treasures."

Colombian Coffee Regions

Colombia's specialty coffee regions are concentrated in the south, mostly at altitudes above 1,500 meters, covering San Agustin in Huila, Popayan in Cauca, Narino, and Tolima.

From north to south, Colombia's main coffee regions include: Santander and Norte de Santander: Located in northern Colombia, bordering the Magdalena River to the west, with cultivation at about 1,400 to 1,600 meters. Coffee from this region is known for its strong taste, long finish, and unique herbal aroma. Antioquia: Located in the north-central area, with 126,000 hectares of coffee cultivation, accounting for 18% of Colombia's total production, second only to Huila. Most of the department lies in the highlands of the Andes, while also being brushed by warm Caribbean sea breezes. The capital, Medellin, is Colombia's second-largest city and an important coffee-producing region.

Tolima: Adjacent to Huila and Cauca, with the Andes and Cordillera mountains running north-south through the entire department. Between these two famous mountain ranges, the Magdalena River flows from south to north.

Huila: Located at the southern end of Colombia's Central Cordillera in the south of the country, it is the nation's most famous specialty coffee region. Surrounded by mountains, with cultivation at altitudes above 1,500 meters, Colombia's most important rivers converge here, bringing abundant water resources and moisture.

Cauca: A region certified under Colombia's coffee denomination of origin, with an average altitude of 1,758 meters, reaching up to 2,100 meters. The local terrain, rainfall, temperature, and volcanic soil provide ideal conditions for coffee growing. 80% of the department is mountainous, with parallel mountain ranges in the east and center that are part of the Andes; the central range includes two major volcanoes, Sotara and Petacas. Narino: Bordering the Pacific Ocean to the west and Ecuador to the south, with the Andes running through the entire department and several rivers flowing southward through it, this is a high-mountain coffee-growing region of Colombia that has nurtured many small specialty coffee farmers. Narino was also Colombia's first coffee region named after its place of origin.

Colombian Coffee Bean Varieties Colombian Coffee Varieties In addition to the Caturra, Bourbon, Typica, and Pacamara commonly seen in American-producing regions, Colombia also has three unique disease-resistant varieties: Castillo, Tabi, and the Colombia variety that shares the country's name. There are also rare and precious varieties, such as Geisha, small-bean Mocha, Rume Sudan, Eugenioides, Laurina, Maragogype Geisha, and Pink Bourbon.

Today Front Street Coffee will focus on Pink Bourbon. This variety was bred from a cross between Red Bourbon and Yellow Bourbon and was first planted in the Huila region. At first it was mixed in with other Bourbon and Caturra plants, and only later was it harvested and processed separately. When the coffee cherries ripen, they take on a romantic pink color, but maintaining this color consistently is extremely difficult—the color of the fruit is ultimately determined by recessive genes in the pollen grains. The pollen grains involved in the cross may carry either the yellow gene leaning toward Yellow Bourbon or the red gene leaning toward Red Bourbon, and these are all recessive genes that easily interfere with one another, making Pink Bourbon a very rare variety.

Colombian Coffee Bean Processing Methods

Washed processing is the mainstream method for Colombian coffee beans. Friends who often buy Front Street Coffee's daily bean series will notice that most Front Street daily beans use the washed method. This is because washed processing can present a region's basic flavor and is also the starting point for understanding a region's flavor. Compared with natural processing, washed processing makes it easier to control coffee bean quality; the key is to slow down the "fermentation" process by washing the coffee clean. At the same time, because it consumes a large amount of water, washed processing is less common in countries with scarce water resources.

【Washed Method】 1. Bean selection: Pour the harvested cherries into a large tank. Ripe cherries sink to the bottom, while unripe or overripe cherries float on the surface. 2. Remove pulp: Use a machine to strip off the skin and pulp, leaving only the coffee beans wrapped in mucilage. The washing process is meant to wash off this layer of mucilage. 3. Fermentation: Mucilage clings strongly and is not easy to remove, so it must be placed in a tank for about 18 to 36 hours, using microbial fermentation to break down the mucilage. 4. Washing: Put the fermented beans into a water tank and rinse them back and forth, using the friction between the beans and the water flow to wash the coffee beans clean. 5. Drying: After washing, the moisture content of the coffee beans is about 50%, and they need to be dried until the moisture content drops to 12%; otherwise, too much moisture can lead to mold and spoilage. The best method is sun drying. Although it takes 1 to 3 weeks, the flavor is excellent. Some places use machine drying, which greatly shortens processing time, but the flavor is relatively not as good as beans dried in the sun. 6. Hulling: After drying is complete, the coffee beans are stored in a warehouse for one week (to stabilize moisture content), then sent to a factory for hulling to remove the parchment layer. 7. Sorting and grading: Remove defective beans to ensure better quality, then hand them over to exporters to be sold around the world.

From the washed method also came semi-washed and anaerobic washed processing. Front Street Coffee below will introduce three Colombian Pink Bourbon coffees that use washed, semi-washed, and anaerobic washed methods respectively. 【Semi-Washed】 Semi-washed is an improved processing method developed to reduce the water consumption of the traditional washed method. The earlier steps of screening floating beans and removing pulp are the same as in the washed method, but when removing mucilage, it is scraped off directly by machine, omitting the soaking fermentation and washing rinse stages. The drying process uses natural sun drying or mechanical drying until the moisture content reaches 12%. The flavor of semi-washed beans falls between natural beans and washed beans, with lower acidity than washed beans and less sweetness than natural beans.

【Anaerobic Washed】 The coffee beans are fermented in an oxygen-free container. After ripe coffee cherries are harvested, they first undergo 12 hours of dry fermentation in polypropylene woven bags. After this step, the coffee is depulped and dehulled, ready for the second round of fermentation. In the second round, the coffee beans need to ferment for 24 hours in an anaerobic environment—they are transferred to plastic tanks and sealed to block oxygen circulation. After the two steps are completed, the coffee beans are slowly dried on raised beds for 20 to 25 days, until the moisture content drops to between 10% and 12%. Anaerobic processing is highly challenging for the operator, because it is very easy to over-ferment, making the coffee taste more like vinegar than fruit.
