Starbucks is renowned for its rich and flavorful coffee, but many coffee drinkers may not know the intricate steps that go into processing the coffee beans. Each cup of Starbucks coffee is the result of a detailed and methodical journey, from the farms where the beans are grown to the final roasting process. In this article, we will take you through the essential stages of coffee bean processing used by Starbucks, including harvesting, sorting, depulping, fermentation, drying, hulling, roasting, and quality control. Additionally, we will explore the company’s commitment to sustainability practices to ensure that every cup of coffee you enjoy is of the highest quality.
Harvesting
The journey of a Starbucks coffee bean begins in the lush coffee-growing regions of the world. Starbucks sources its coffee from several countries, including Colombia, Guatemala, Ethiopia, Kenya, and Costa Rica. These regions are known for their ideal climates, rich soil, and high altitudes, all of which contribute to the unique flavors found in each coffee.
Coffee beans start their life as coffee cherries, and the harvesting process plays a critical role in determining the quality of the beans. The cherries must be carefully picked when they are fully ripe to ensure that the coffee beans inside have the right flavor profile. Starbucks employs a method called selective picking, which involves picking only the ripe cherries from the coffee plant. This is a labor-intensive process, but it guarantees that only the best cherries are chosen for further processing.
Selective picking allows Starbucks to maintain a high standard of quality in their beans. While it may take longer than other methods, it ensures that the beans will have the optimal taste and aroma once they are roasted. Ripe cherries are typically a vibrant red color, and picking them at their peak ensures that the beans inside are full of flavor.
Sorting and Cleaning
Once the coffee cherries are harvested, they undergo a rigorous sorting process to ensure that only the best beans move on to the next stage. This sorting process involves removing any unripe, damaged, or overripe cherries that could negatively affect the quality of the coffee.
Unripe cherries are often green, and while they may look tempting, they lack the sweetness and flavor of their ripe counterparts. Overripe cherries, on the other hand, are usually too soft and may have begun to ferment, resulting in an undesirable taste. By carefully removing these subpar cherries, Starbucks ensures that only the best beans are processed.
After the cherries have been sorted, they are cleaned thoroughly to remove any debris, dirt, or dust. This cleaning process helps prevent any contaminants from affecting the flavor of the beans. The cherries are washed in clean water, and sometimes, mechanical equipment is used to help remove any unwanted materials that may have clung to the cherries during harvesting and transportation.
Depulping
Depulping is the process where the pulp and skin of the coffee cherries are removed to reveal the green coffee beans inside. The depulping process is essential, as it allows the beans to be further processed and refined before they are roasted.
Traditionally, depulping was done manually, but Starbucks has adopted eco-friendly methods in this stage. Modern depulping machines are often used, which use less water and energy compared to older methods. These machines gently remove the pulp and skin from the cherries, ensuring that the beans are not damaged during the process.
After the cherries are depulped, the beans are left with a thin layer of mucilage, which will need to be removed during the fermentation process. The depulped beans are typically placed in large containers or bins where they will begin the fermentation process, which plays a significant role in enhancing the flavor of the beans.
Fermentation
Fermentation is a crucial stage in the coffee processing process that helps develop the flavors of the beans. During this stage, the thin layer of mucilage left on the beans after depulping is broken down by naturally occurring microorganisms. These microorganisms, mainly bacteria and yeast, consume the sugars in the mucilage and break it down into simpler compounds.
This fermentation process can take anywhere from 12 to 48 hours, depending on the temperature and humidity of the environment. As the mucilage breaks down, it enhances the flavor profile of the beans by removing any unwanted bitterness. The fermentation stage allows the beans to develop more complex and nuanced flavors, contributing to the distinctive taste of Starbucks coffee.
While fermentation is a natural process, Starbucks ensures that it is carefully monitored to prevent over-fermentation, which can result in off-flavors. The company uses best practices and modern equipment to control the fermentation environment, ensuring that each batch of beans has the optimal fermentation time.
Drying and Hulling
Once the beans have undergone fermentation, they are ready for the drying process. Coffee beans must be dried to a specific moisture content in order to preserve their quality during storage and transport. Starbucks employs both traditional and modern drying methods to ensure that the beans are dried evenly and thoroughly.
The beans are typically spread out in thin layers on drying beds or large drying patios, where they are exposed to the sun’s warmth. In some cases, mechanical dryers are used to speed up the process, especially when the weather is not conducive to natural drying. Regardless of the method used, the beans are carefully monitored to ensure they do not dry too quickly or unevenly, as this can result in poor flavor development.
After the beans are dried, they undergo the hulling process. Hulling involves removing the outer layers of the coffee beans, known as the parchment or husk. This step ensures that only the clean, green coffee beans remain, ready to be shipped to Starbucks roasting facilities around the world. The hulling process is typically done using mechanical equipment that gently removes the husk without damaging the beans inside.
Roasting
Roasting is the stage that transforms the green coffee beans into the aromatic, flavorful beans that we know and love. Starbucks is known for its distinct roasting techniques, which produce a wide range of flavors to suit different tastes. The company uses a variety of roasting levels, from light to dark, to achieve the desired flavor profile for each coffee blend.
Starbucks uses high-quality roasting equipment, such as drum roasters, to ensure that the beans are roasted evenly. The roasting process involves heating the beans to specific temperatures, causing chemical changes that develop the coffee’s flavor. During roasting, the beans release gases and oils, which contribute to their flavor, aroma, and body.
Starbucks offers a range of roasts to cater to diverse customer preferences, including its signature blonde, medium, and dark roasts. Each roast level is carefully crafted to bring out different aspects of the beans’ natural flavors. For example, light roasts tend to have bright, fruity flavors, while dark roasts have a bold, smoky taste. Starbucks uses expert roasters who carefully monitor the roasting process to ensure consistency and quality in every batch.
Quality Control
At every stage of the coffee processing journey, Starbucks places a strong emphasis on quality control. From the selection of ripe cherries to the final roasting process, the company has established rigorous quality control measures to ensure that each cup of coffee meets its high standards.
Starbucks works closely with coffee farmers and suppliers to ensure that the beans are grown and harvested using best practices. The company also conducts frequent quality checks during the sorting, cleaning, depulping, and fermentation stages to maintain consistency and prevent any defects from affecting the final product.
Once the beans reach the roasting facility, they undergo additional quality control checks. Expert cupping, or coffee tasting, is performed to assess the flavor, aroma, and overall quality of the beans. Starbucks’ highly trained tasters evaluate each batch of beans to ensure that they meet the company’s flavor profiles and standards.
Sustainability Practices
Starbucks is committed to sustainable and ethical sourcing practices throughout its coffee bean processing journey. The company recognizes the environmental and social impact of coffee production and works to minimize its footprint while supporting the communities that grow the coffee.
One of the key sustainability initiatives of Starbucks is its Coffee and Farmer Equity (C.A.F.E.) Practices, which promote ethical sourcing and ensure that farmers are paid fair wages. These practices focus on improving the livelihoods of coffee farmers, promoting environmental sustainability, and ensuring transparency in the supply chain. Starbucks also invests in programs that help farmers adopt environmentally friendly farming techniques, such as using organic fertilizers, reducing water usage, and conserving biodiversity.
In addition to its ethical sourcing efforts, Starbucks is also focused on reducing its environmental impact. The company has implemented initiatives to reduce waste, conserve energy, and minimize water usage in its coffee bean processing facilities.
