Starbucks Autumn Blend, also known as Thanksgiving Blend, is a seasonal limited-edition blend. Based on beans from two classic origins—Sumatra and Antigua, Guatemala—this coffee combines them in precise proportions to deliver a rich and layered autumn flavor profile. This article explores the regional characteristics and processing technologies, analyzing the essential differences between Asian/Pacific and Latin American coffees, and detailing the key steps of washed and semi-washed processing methods to help readers better understand the logic behind the blend. Additionally, practical pour over recommendations are provided at the end to help you recreate a café-quality brew at home.
[Regional Flavor Characteristics]
The geographic environment of an origin directly influences the flavor profile of its coffee. Coffees from Asia/Pacific regions, such as Sumatra in Indonesia, typically exhibit a full-bodied, sweet, and smooth character, accompanied by unique herbal and earthy aromas. Coffee from this region is often processed using the semi-washed method, which enhances body and adds complexity with spicy notes. The acidity is relatively mild, but herbal and soil-like flavor characteristics are distinct. It’s worth noting that while Papua New Guinea and Timor also produce washed coffee, Starbucks primarily selects semi-washed beans to highlight more recognizable traits.
In contrast, Latin American origins—including countries in Mexico, Central America, and South America—are major suppliers for Starbucks. Before 2009, Latin American coffee accounted for more than half of Starbucks’ total purchases. These regions commonly use the washed processing method, emphasizing bright acidity, clean cup profiles, and balanced flavors of nuts, cocoa, and subtle spices. The consistency and quality stability of washed coffee make it an ideal base for Starbucks blends.
[Processing Differences]
The processing method is one of the key factors determining a coffee’s flavor expression. The washed method uses water flow and fermentation to remove the pulp and mucilage layer, leaving behind clean beans with bright acidity. The specific process includes: after harvesting the coffee cherries, the outer skin is first removed, followed by 18–36 hours of fermentation to break down the mucilage. Residues are then washed away, and the beans are dried for 5–7 days either on outdoor patios or in mechanical dryers. After drying, the beans rest for two months to develop their flavors, and finally, the parchment layer is removed to complete the process. This method enhances acidity and aroma, resulting in a brighter and livelier cup.
The semi-washed method, also known as honey processing or wet hulling, emphasizes herbal, earthy, and bold, full-bodied characteristics. This method is common in Sumatra, Indonesia, and involves the following steps: first, the pulp is removed on the farm, then the beans are soaked for 1–2 hours and manually rubbed to remove some mucilage without undergoing full fermentation. The beans are then partially dried in a low-humidity environment until the moisture content drops to about 24%, and further dried down to 10%–12%. This process retains more of the coffee’s native flavor compounds, giving it unique earthy and spicy tones.
[The Story Behind Autumn Blend]
This Autumn Blend was first introduced in 2008 under the name Thanksgiving Blend and was sold as a seasonal product from 2008 to 2011. In 2009, the design team chose warm orange and maple leaf motifs to match the autumn atmosphere. From over ten candidate beans, they selected the classic origins of Sumatra and Antigua, Guatemala, blending them in perfect proportions. This coffee has been described as vibrant as spring, capable of awakening the taste buds. It pairs well with sweet and savory pastries or croissants, making it perfect for sharing moments of gratitude with family.
[Practical Pour Over Recommendations]
If you’d like to try pour over brewing this Autumn Blend at home, we recommend using a medium-fine grind size, with water temperature controlled at 90–92°C and a coffee-to-water ratio of 1:15. Brewing can be done in three pours, with a total brewing time of around 2 minutes and 30 seconds to evenly extract the balanced flavors of nuts and cocoa. Keep the water flow steady and avoid over-extraction, which can lead to bitterness. Proper grind size and water temperature control are key to highlighting the layered complexity of this blend.
