How Do You Build an Espresso Blend With Colombian Beans?

Blending coffee beans means combining origins so the cup tastes better than any single bean could alone. A common example is a nutty espresso recipe that pairs Colombian beans with Brazilian beans, roasted separately and then mixed in a set ratio to keep flavor steady from batch to batch.

The usual approach is a 3:7 post-roast blend of Colombian and Brazilian beans, which suits home brewers who want cafe-style flavor and more consistent output. Commercial blending often aims at lower cost or a signature taste, but blending coffee for flavor starts with knowing each origin's characteristics before mixing.

Blending coffee beans is not a simple mixing process, but an art that combines scientific calculation with sensory experience. From the practical perspective of Front Street Coffee, this article systematically sorts out the purposes of blending, the order of blending and roasting, as well as the blending steps and core principles, helping coffee enthusiasts understand how to build a nutty espresso recipe with Colombian and Brazilian coffee beans. The article also introduces the product concepts of Front Street Black Cocoa Blend and Sunflower·Warm Sun Blend, and includes a recipe example of a 3:7 post-roast blend of Colombian and Brazilian beans, suitable for readers who want to recreate cafe flavors at home or optimize output consistency.

Many friends who are new to coffee are curious about what exactly the formula for a blended bean is designed around. Front Street Coffee (FrontStreet Coffee) will now talk with everyone about the ideas behind blending coffee beans, and how to make a blended coffee by hand.

The reasons and purposes of blending

There are often several different motives behind why people mix coffee beans from different origins together. The most ideal starting point is, of course, to create a cup of coffee better than any single bean type. However, generally speaking, single-origin Arabica coffee can already produce a quite good taste—fresh aroma, soft texture, and a sweet aftertaste. Therefore, purely from the perspective of flavor, there is actually not necessarily a need for "blending" (that is, mixing beans from different origins together).

A more common commercial motive for blending coffee beans is to reduce costs, using average-quality coffee to blend a relatively balanced taste, thereby increasing profit margins. Another possible purpose is to create a unique flavor so that customers who prefer this taste can only buy it from this one manufacturer and cannot obtain it from other suppliers. This also has an accompanying benefit: regardless of how the flavor of coffee from certain origins fluctuates in a given year, the taste of this blended coffee can remain relatively consistent.

Here we will first set aside other commercial considerations and focus on blending aimed at improving flavor quality.

In Front Street's view, before starting to blend, the first step is to master the flavor characteristics of each coffee, and at least be clear in your mind: the taste you want to blend should be something no single-origin coffee can achieve. If the blended result is not as good as one or several of the beans perform on their own, that would be a pity, and it would be better not to blend at all. If you use coffee that is already of good quality for blending, you may very well end up in this awkward situation.

Although some fixed varieties of coffee can be drunk directly as single-origin coffee, most coffees have some shortcomings in flavor, such as lacking distinctiveness, insufficient layering, insufficient strength, or some taste being too prominent. To fill these gaps, it is necessary to combine several coffee beans with different characteristics to create a coordinated and deep flavor. Some people feel that the pleasure of coffee is concentrated precisely in the two stages of roasting and blending, and that drinking coffee is merely enjoying the results of one's own efforts. Blended coffee is absolutely not as simple as casually mixing beans into a pile.

Sometimes, two single-origin coffees blended together will instead suppress each other's unique flavors, so blending should not be understood as simply stacking several single-origin coffees together. Blending is like a painter mixing charming colors on a palette; a blender can likewise use coffee beans to mix an alluring taste. It is not an exaggeration at all to say that blending is an art. As an artist, in addition to experience and inspiration, one also needs the help of certain scientific calculations. The birth of a work of art is not accidental, but an outburst after long-term accumulation. Usually a blended coffee does not need to use more than five kinds of coffee beans, because once there are too many bean types, the variables become very complex, and probably only a very few experts will not be confused by so many different beans.

Front Street Coffee (FrontStreet Coffee) focuses on freshly roasted coffee, and also launches blended coffees with different positioning according to the needs of different customers. For example, for customers seeking cost-effectiveness, Front Street recommends an espresso bean recognized by many baristas—Front Street Black Cocoa Blend. This all-Arabica espresso bean blended from Brazil and Yunnan has a price advantage and outstanding flavor. For customers who value flavor performance more, Front Street launches Sunflower·Warm Sun Blend, blended from Yirgacheffe natural red cherry and Honduras Sherry. With its ultimate rum chocolate flavor, it is loved by many customers.

The relationship between blending and roasting

Should you roast first and then blend, or blend first and then roast? Which method is more ideal?

Front Street Coffee (FrontStreet Coffee) believes that if you already have a set formula, then the most convenient approach is naturally to first mix different coffee beans in proportion, and then roast them together. But if you are still trying and comparing different blending components and ratios, then of course you would rather first roast each kind of bean separately, and then do various combination tests. Otherwise, every time you adjust the components and ratios, you have to roast again.

In the field of roasting, blending first and then roasting is usually called "green blending," while roasting first and then blending is called "roasted blending." Actually, there is no saying that one of these two methods is superior or inferior. The advantage of green blending is that roasting the same batch of beans together can make the roast degree of the whole batch more consistent, and the flavor more stable; but when selecting beans, try to choose beans with similar screen sizes to mix, otherwise it is very likely to roast unevenly. Roasted blending, on the other hand, allows you to separately control the optimal roasting attributes of each bean before mixing, making it easier to make up for each other's shortcomings.

Under normal circumstances, all coffee beans can be roasted together. Only when the roasting effect is not ideal should you consider roasting them separately. In such cases, separate roasting often achieves better results. Especially for drum roasters, generally a relatively moderate roast level can be found.

General steps and principles of blending

Before blending coffee beans, we should first clarify the following points:

1. The theme of the blend, that is, what kind of taste you want to create, in other words, determining the goal of the blend.

2. Understand the characteristics of each coffee bean. To blend coffee, you must first be thoroughly familiar with the characteristics of each single-origin coffee and understand the subtle relationship between roast degree and coffee flavor, and all of this can only be achieved through cupping.

3. Determine the respective roles of the coffee beans participating in the blend. Since multiple coffee beans are used in combination, you must be clear about what each bean is responsible for—whether it is meant to highlight a soft bitterness, a bright acidity, or a heavy body, and so on.

When blending, the following principles should generally be followed:

1. The raw beans used for blending should each have their own characteristics; avoid using coffee beans with similar flavors. When selecting raw beans, you can consider three aspects:

Green bean processing method: whether the green beans are processed by the washed method or the natural method. The processing method has a great relationship with the flavor of the coffee beans.

Green bean origin: coffee origins are generally divided into three major regions, including Central and South America, namely about 20 countries such as Brazil, Colombia, Guatemala, Mexico, El Salvador, Jamaica, and Peru; Southeast Asia, namely about 10 countries such as India, Indonesia (including islands such as Java and Sumatra), and Papua New Guinea; and Arabia and Africa, namely about 25 countries such as Ethiopia, Kenya, Tanzania, Arabia, and Uganda. As mentioned earlier, the most commonly used raw beans on the market are Brazil and Colombia.

2. The number and proportions of coffee bean types participating in the blend

Since it is a blend, it naturally refers to a combination of two or more raw beans, but beans of the same kind roasted to different degrees can also be blended together, and even new beans and aged beans or old beans of the same coffee can be blended. Therefore, the "types" referred to in blending are no longer just coffee varieties in the narrow sense, but broadly extend to the level of coffee flavor. Blending generally uses 2 to 6 kinds of coffee beans; too many types make it difficult to express the unique flavor of coffee. Blended coffee generally does not use a 1:1 ratio, because this may mutually suppress the other's unique flavor. Therefore, when blending, there must be a distinction between primary and secondary so that a more wonderful taste than single-origin coffee can be created. If you want the blended coffee to have a complex and varied taste, you can reduce the proportion of the theme raw beans, and vice versa.

3. Blended coffee relies on continuous experimentation

Before blending, you should draft a blending plan in a mathematical combination manner, and then determine the best scheme through the process of blending and cupping. Do not think this is a passive and clumsy method; in fact, only through the blender's experience, inspiration, and this tireless experimentation can a good cup of coffee be blended.
