When first encountering the concept of blended coffee, many beginners may feel confused—what exactly does blended coffee mean? In fact, most of the coffee we drink daily belongs to blended coffee, which is coffee made by mixing multiple varieties, multiple origins, or coffee beans of different roast levels in certain proportions. Front Street Coffee would like to share a little experience: blended coffee often performs better in flavor than single-origin coffee.

Reasons and Purposes for Blending

People combine coffee beans from different origins for various reasons. The most ideal starting point is, of course, to create a taste better than any single origin. However, in most cases, single-origin Arabica coffee beans can already make coffee of quite good quality—fresh aroma, soft mouthfeel, and sweet aftertaste. Therefore, from a flavor perspective, blending is not necessarily required.

The main commercial motive for blending coffee beans is to reduce costs, using coffee beans of average quality to create relatively balanced-tasting coffee, thereby increasing profit margins. In addition, there is another possible goal: to create a unique flavor through blending, so that consumers who prefer this taste can only buy it from a specific manufacturer and cannot obtain the same product from other suppliers. This also has an added advantage: regardless of how the coffee flavor of certain origins fluctuates in different years, the taste of this blend can always remain consistent.

Here we first set aside other commercial considerations and specifically discuss blending aimed at improving coffee flavor quality.

Before doing any blending, Front Street believes that one first needs to master the flavor characteristics of various coffees and at least have a clear expectation in mind—that the coffee one wants to blend should have a taste that no single-origin coffee can achieve. If the blending result is instead inferior to the performance of one or several of the coffees in it, that would be a pity, and it would be better not to blend at all. If the coffee beans selected for blending are themselves of quite excellent quality, this situation is very likely to occur.

Although some fixed varieties of coffee can be drunk directly as single-origin coffee, most coffees have one deficiency or another in flavor, such as lacking a unique flavor, insufficient layering, insufficient strength, or some taste being too prominent. To make up for these shortcomings, it is necessary to combine several coffee beans with different characteristics to create a coordinated and deep taste. Some people think the pleasure of coffee lies precisely in the two stages of roasting and blending, and drinking coffee is merely enjoying the results of one's own efforts. Blended coffee is by no means as simple as casually mixing coffee beans together.

Sometimes two single-origin coffees will instead suppress each other's distinctive flavors after blending, which shows that blending is not simply putting 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. So it is not an exaggeration to say that blending is an art. As artists, they not only need experience and inspiration, but also need the help of certain scientific calculations. The birth of a work of art is never accidental, but an outburst after long-term accumulation. Usually, a blended coffee uses no more than five kinds of coffee beans. Because once there are too many types, the situation becomes very complicated, and probably only extremely professional experts would not be confused by so many different beans.

Front Street Coffee focuses on freshly roasted coffee and has launched a variety of blended coffees for the needs of different customer groups. For example, for customers who value cost performance, Front Street recommends an espresso coffee bean recognized by many baristas—Front Street Black Cocoa Blend. This product is blended from all-Arabica beans from Brazil and Yunnan, combining price advantage with excellent flavor. For customers pursuing flavor, Front Street has launched Sunflower·Warm Sun Blend. This product is blended from Yirgacheffe natural red cherry and Honduras Sherry, and has won the favor of many guests with its ultimate whiskey bonbon flavor.

The Relationship Between Blending and Roasting

Should coffee be roasted first and then blended, or blended first and then roasted? Which method is better?

Front Street Coffee's view is that if you already have a confirmed formula, then the simplest method is naturally to first mix different coffee beans in proportion and then roast them together. But if you are trying and comparing different blending combinations and proportions, then of course you want to first roast each kind of coffee bean separately and then conduct various pairing experiments. Otherwise, every time you adjust the blending components and proportions, you have to roast again.

In the roasting field, blending first and then roasting is usually called "raw blending," while roasting first and then blending is called "roasted blending." These two methods actually have no absolute superiority or inferiority. The advantage of raw blending is that roasting the same batch of beans together can make the roast level of the whole batch more consistent and the flavor more stable, but when selecting beans, one needs to choose beans of similar screen size for mixing, otherwise uneven roasting is very likely to occur. Roasted blending can handle each coffee bean individually according to its best roasting attributes, and when mixing afterward, it can better make up for each other's shortcomings.

Usually all coffee beans can be roasted together. Only when roasting results are unsatisfactory is it necessary to consider separate roasting. At this time, separate roasting often achieves better results. Especially for drum roasters, a relatively moderate roast level can generally be found.

General Steps and Principles of Blending

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

1. The theme of the blend—what kind of taste you hope to create, that is, 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 level and coffee flavor, and all of this can only be achieved through cupping.

3. Determine the respective tasks undertaken by the coffee beans participating in the blend. Since multiple coffee beans are used in the blend, it is necessary to be clear about the role of each bean, whether it is to highlight a soft bitterness, a bright acidity, or a heavy body, etc.

When blending, the following principles should generally be followed:

1. The raw beans used in the blend should each have distinctive characteristics; avoid choosing coffee beans with similar flavors. The selection of raw beans can be considered from three aspects:

Green bean processing method: whether the green beans are processed by the washed method or the natural method; the processing method is closely related to coffee bean flavor.

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 the Arabian and African regions, 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 proportion 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 coffee beans of the same type at different roast levels can also be blended together, and even new beans of the same coffee type can be blended with aged or old beans. Therefore, the "types" referred to in blending are no longer coffee varieties in the narrow sense, but broadly extended to the level of coffee flavor.

Blending generally uses 2 to 6 kinds of coffee beans, because too many types make it difficult to show the unique flavor of the coffee. Blended coffee usually does not use a 1:1 ratio, as this may suppress each other's distinctive flavor tonality. Therefore, when blending, there must be a distinction between primary and secondary so that a taste more wonderful than single-origin coffee can be created. If you want the blended coffee to have complex and varied flavor layers, you can appropriately reduce the proportion of the theme raw beans, and vice versa.

3. Blended coffee depends on continuous experimentation.

Before blending, a blending plan table should be drawn up using mathematical combinations, and then the best solution should be determined through the process of blending and cupping. Do not think this is a passive and clumsy method; in fact, only by relying on the blender's experience, inspiration, and this tireless repeated experimentation can a good cup of coffee be blended.
