How Are Blended Coffee Beans Used in Espresso Recipes?

Blended coffee beans combine single-origin lots from different regions in set proportions so their strengths offset each other's gaps and produce a more balanced, consistent cup. Three representative espresso recipes are covered here: a Specialty Blend of Colombia Huila and Brazil Cerrado, a Commercial Espresso Blend with Robusta added, and a Basic Espresso Blend pairing Yunnan AA with Brazil.

The trade-off between pre-roast and post-roast blending runs through all three recipes. Post-roast blending lets each component be roasted to its own level before mixing, while pre-roast blending mixes green beans first. The article also records altitude, variety, and processing details from each origin, plus the flavor direction and suitable uses after blending, which helps both home enthusiasts and shop owners.

Blended coffee beans are made by mixing single-origin coffee beans from different regions in certain proportions, allowing their respective strengths to complement or reinforce one another, thereby achieving a more balanced and stable flavor profile. This article revolves around the core logic of espresso blending, first explaining the trade-offs between the two processes of pre-roast blending and post-roast blending, then sharing three representative recipes from Front Street Coffee one by one: the Specialty Blend (Colombia Huila × Brazil Cerrado), the Commercial Espresso Blend (with Robusta added), and the Basic Espresso Blend (Yunnan AA × Brazil). The article records in detail the altitude, variety, processing method, and roasting approach of beans from each origin, and provides the flavor direction and applicable scenarios after blending, making it suitable for coffee enthusiasts and those opening a shop for reference.

The Art of Front Street Coffee's Blended Coffee Beans and Espresso Blend Recipes Shared

Blended coffee, also known as mixed coffee, is the mixing of various single-origin coffee beans together, thereby fully bringing out the strengths of each single-origin coffee bean. Blended beans are made by mixing coffee beans from different origins to create a more balanced taste. For example, if one coffee bean is smooth but lacks aroma, you can add another bean rich in aroma, so that the advantages of individual coffee beans complement each other, whether complementing or reinforcing one another in taste, thereby creating a richer new taste in a coffee. Sometimes the beans are mixed first and then roasted, which is called pre-roast blending; sometimes the coffee beans are roasted first and then mixed, which is called post-roast blending.

Whether pre-blending green beans or roasting individually and then blending, it must depend on the characteristics of the coffees in the recipe. Both methods are acceptable. Post-roast blending provides different degrees of roasting for each bean, so that each component can show its best effect.

Before blending beans, you must first know what flavors coffees of different varieties around the world have. Beans have different characteristics depending on their origin. Different coffee beans have different personalities due to different varieties and origins, with subtle differences in flavor such as acidity, bitterness, sweetness, aroma, and body. Single-origin coffee beans often focus more on expressing the unique characteristics of a certain type of coffee. Blended beans are mostly used for espresso drinks such as Espresso, Americano, Latte, or Cappuccino. The coffee taste is more balanced, smoother, and more stable, and can be said to be more suited to mass taste.

So, how do we blend?

(1) Front Street Coffee Specialty Blend Coffee Beans: Colombia : Brazil

Colombia Huila Region

Located in southwestern Colombia, it is one of the main coffee cultivation areas. Colombia generally has an altitude of 1500-1800 meters, mostly Bourbon and Caturra varieties, washed processing method, relatively high density, uniform bean size, and plump bean shape (thicker from the core to the surface). Because the Huila region is full of famous coffee cultivation areas, the names of various small areas have become brand names and circulate. Although the cultivation conditions in this region are also very good, the cultivation infrastructure of coffee farms and surrounding conditions is not yet very developed. The green bean drying equipment or washed processing facilities are not yet complete, which is a very regrettable point. Coffee from the Huila region has a strong taste and a heavier body. In particular, the nutty, chocolate, and caramel aromas and suitable acidity of coffee from the Huila region can be called premium specialty coffee. And aromas such as caramel and suitable acidity can be called premium specialty coffee.

Flavor characteristics: rich and solid mouthfeel, with a pleasant acidity, aromatic and mellow smell, moderate acidity, and rich sweetness that is very thought-provoking. Because it is cheap and the beans are small, it is suitable for blending mixed coffee. The coffee has a strong taste and a heavier body. Its nutty, chocolate, and caramel aromas and suitable acidity can be called premium specialty coffee, suitable for single-origin use or as an espresso blend base.

Brazil Cerrado Region

Brazilian coffee generally grows at an altitude of 1000-1300 meters, so its density is relatively low. Mostly Bourbon variety, using semi-washed processing. The moisture content is moderate, the bean texture is relatively soft, and the thickness from the bean surface to the core is relatively thin, so it is not suitable for roasting at too high a temperature. The temperature of the inner wall of the roaster will scald the bean surface, which will produce a burnt bitter taste;

At the same time, if you want to express the characteristics of nuts, milk chocolate, and better body, and use it as a blend base, we adopt the method of charging beans at medium heat, maintaining the heat until the dehydration stage, and after the start of first crack, making fine adjustments as the temperature rises, promoting a more sufficient caramelization reaction, and when the temperature rises to near second crack, the beans can be discharged.

Flavor characteristics: comfortable sweet-bitter taste, extremely smooth on the palate; with a faint grassy aroma, fresh and slightly bitter; sweet and smooth, with a finish that makes one feel comfortable;

Flavor after blending: a sweet and fragrant mouthfeel. Using a medium-dark roast, when making espresso, the taste will have soft slight acidity, fresh sweetness, and a nutty sweet aftertaste. The overall feeling is not too stimulating, mellow, with medium crema, meeting the daily output needs of a coffee shop.

(2) Front Street Coffee Commercial Espresso Blend Beans: Colombia : Brazil : Robusta

[Robusta] beans have strong resistance to pests and diseases and high yield. They usually do not have the acidity of Arabica beans and often carry a slight woody aroma. The caffeine content is 2.2%, higher than Arabica beans' 1.2%, and the chlorogenic acid content is also higher. They are also quite bitter and are usually used in commercial beans, with a cost lower than Arabica beans.

In terms of the flavor of a single bean, the coffee obtained from commercial beans is much inferior to the taste of specialty coffee beans. Generally, commercial beans are chosen for blending. Through blending, a very good-tasting coffee can also be made, which can be used to make espresso drinks such as lattes and cappuccinos. And when we make Espresso with our commercial blend, because of the Robusta beans, the crema will be richer, the taste classic, with caramel sweetness, nutty and cocoa-like, dark chocolate flavors, balanced acidity and sweetness, slightly sweet-bitter, and a lasting finish, suitable for the daily output of a coffee shop.

(3) Front Street Coffee Basic Espresso Blend Coffee Beans: Yunnan AA : Brazil;

Our Yunnan AA is [Typica], the oldest native variety from Ethiopia, produced in Ethiopia and southeastern Sudan. All Arabica varieties are derived from Typica. The top leaves are copper-red, called red-top coffee. The flavor is elegant, but the plant constitution is relatively weak, disease resistance is poor, and it is prone to leaf rust, with low fruit production. Typica has four slender branches, spreading outward, with an inclination angle of 50~70 degrees. The opposite leaves are long oval-shaped, with a smooth surface. The branches at the ends are very long and have few lateral branches, while the flowers are white and bloom at the base where the leaf stalk connects to the branch. The ripe coffee cherry looks like a cherry and is bright red.

During cultivation, it needs more shade coverage and can usually only be harvested once every two years. Yunnan's high-quality geographical and climatic conditions provide good conditions for coffee growth. The planting areas include Lincang, Baoshan, Simao, Xishuangbanna, Dehong, and other prefectures. Yunnan's natural conditions are very similar to Colombia's, with high altitude and a large temperature difference between day and night. The flavor is of the mellow-aroma type, with moderate acidity, a rich and mellow taste, uniform bean size, high oil content, and fruity aroma. Its quality and taste are similar to Colombian coffee.

Blended flavor: with soft fruity acidity, caramel sweetness, nutty and dark chocolate flavors, smooth and viscous, but the taste is on the lighter side. This cost-effective espresso blend bean is suitable for shop owners and home users who prioritize cost and have general requirements for flavor.

When blending, there must be a distinction between primary and secondary components in order to blend a more wonderful taste than single-origin coffee. Before formulating a blending plan, first envision a more suitable combination method, then blend through appropriate roasting, and determine the best plan through cupping and later adjustments. I hope this helps everyone~
