What Does Blending Coffee Beans Mean for Espresso?

Blending coffee beans means combining beans from different origins, and it became the standard for espresso because single-origin coffee often tastes one-sided and costs more. Italian roasters blended for a richer, sweet-bitter cup at a lower price. A Yunnan-based dark cocoa blend is a common entry point: it works in moka pots and suits espresso beginners who want lower cost without losing body.

The blend usually includes Robusta alongside Arabica. Robusta adds denser crema and a thicker mouthfeel, which matters when milk is involved. Blending can happen before or after roasting, and the timing changes how the flavors settle. For moka pot use, a blend built on Yunnan beans keeps the price down while still delivering cocoa and nut notes.

Single-origin coffee is mostly used for pour-over, while espresso is generally made from blended beans. But must espresso use blended beans? What exactly is a blend? From the perspective of Front Street Coffee, this article systematically sorts out the origin of espresso blends, the purpose of blending, and the difference between pre-roast blending and post-roast blending, and analyzes in detail the flavor characteristics and suitable scenarios of four Front Street blends. The article also specifically introduces the "Front Street Dark Cocoa Blend" based on Yunnan coffee beans, which is highly cost-effective and suitable for moka pots and espresso beginners. Whether you are a coffee enthusiast or a shop operator, you can find ideas for choosing espresso beans that suit you.

Most people familiar with coffee know that single-origin coffee is usually presented via pour-over, while espresso is often made from blended coffee beans. So what exactly are blended coffee beans? Must espresso use blended beans? Next, Front Street Coffee (FrontStreet Coffee) will introduce knowledge related to espresso beans.

What are espresso blend coffee beans?

Espresso blend coffee beans originated in Italy. According to Front Street Coffee (FrontStreet Coffee), the initial rise of Italian blended coffee was because people at the time preferred rich, sweet-bitter espresso, while single-origin coffee had one-sided flavors, with both strengths and weaknesses. In addition, high-quality single-origin coffee beans were more expensive, and blends had an advantage in cost-effectiveness: priced lower than single-origin coffee, yet able to present unique flavors. Therefore, many Italians at the time preferred blended coffee over single-origin coffee, and blended coffee thus developed and continues to this day.

Espresso is more cost-effective than single-origin coffee partly because traditional espresso blends include Robusta varieties. Robusta coffee beans have a full-bodied flavor. Although their cupping score is not as high as single-origin coffee, when paired with single-origin coffee, they can bring richer, denser crema to espresso, and as a base for milk coffee, they can also provide a thick, smooth mouthfeel.

Friends who often drink single-origin coffee know that single-origin coffee refers to traceable Arabica coffee beans from a single origin with a cupping score above 80. Robusta's cupping level does not meet the standard for single-origin coffee, so it is not used as single-origin coffee. In addition, Robusta's growing conditions are relatively simple, and its price is much cheaper than Arabica varieties.

Blended coffee beans naturally refer to a combination of two or more raw beans, but there is a special case: different roast levels of the same coffee bean can also be blended together, and even new beans and aged or old beans of the same coffee bean can be mixed. Therefore, the "types" in blending are no longer limited to coffee varieties in the narrow sense, but broadly extend to the flavor level of coffee. Blending usually uses 2 to 6 kinds of coffee beans; too many types will instead fail to show coffee's unique flavor.

Why blend coffee beans?

The main purpose of Front Street espresso blends is to maintain flavor stability and taste balance. Coffee fruit is ultimately an agricultural product, and its flavor may be unstable each year due to climate and environmental changes. It may be sweeter this year, but not sweet enough next year. Mixing several coffee beans can better solve this problem, at least allowing the coffee flavor tasted each year to remain consistent.

Another key factor is that an espresso machine amplifies the most prominent flavor of coffee beans. For example, the main flavor of Front Street Coffee's (FrontStreet Coffee) Ethiopian Yirgacheffe is citrus-lemon acidity, and an espresso machine will amplify its acidity; while Indonesian Mandheling is mainly herbal, earthy, and bitter, and an espresso machine will amplify its bitterness. Therefore, Front Street Coffee (FrontStreet Coffee) does not use a single variety of coffee beans to make espresso; otherwise, the finished product would be very unbalanced and affect the taste. This is also why espresso should be made with blended coffee beans.

Can single-origin coffee beans be used in an espresso machine to make espresso?

Although Front Street Coffee (FrontStreet Coffee) mentioned above that single-origin coffee is not suitable for making with an espresso machine, it does not mean it cannot be done at all. It is just that espresso made from single-origin coffee beans has another name—SOE coffee. Making SOE coffee requires adjusting the ratio of espresso to milk or water, reducing the amount of milk or water, and highlighting the coffee's own taste so that the coffee is not too weak.

Finally, choosing beans for making SOE also has very strict requirements. Although SOE performs outstandingly, because it comes from a single origin, its shortcomings are relatively easy to amplify. Factors such as roast level and grind size will all affect the flavor. Therefore, SOE coffee is difficult to maintain a stable flavor, and Front Street Coffee (FrontStreet Coffee) does not offer it in-store.

How should Front Street espresso blend coffee beans be blended?

Of course, blended coffee beans cannot be combined arbitrarily. As Front Street Coffee (FrontStreet Coffee) said above, an espresso machine amplifies the original flavor of coffee beans, so Front Street Coffee (FrontStreet Coffee) suggests that blended coffee beans should have similar roast levels and flavors that can integrate and complement each other before blending. Suppose Front Street Yirgacheffe coffee beans were blended with Front Street Indonesian Mandheling coffee beans; it would probably be a "dark" drink. Therefore, coffee bean blending must strictly consider the blending ratio and flavor harmony to create delicious coffee. This also greatly tests the blender's understanding of coffee beans.

In addition, Front Street Coffee (FrontStreet Coffee) mentioned above that espresso blend coffee beans are blended from 2-6 kinds of raw beans, and raw coffee beans naturally still need roasting processing, so blends are further divided into pre-roast blending and post-roast blending.

Pre-roast blended coffee beans

Pre-roast blending is mixing coffee beans before roasting, while post-roast blending is roasting first and then mixing. Front Street believes that the advantage of pre-roast blending is that the same roast level can be used, making the coffee flavor more stable and uniform, and it can be completed in one roast. The same roast level can also greatly reduce quality control difficulty and improve efficiency.

But pre-roast blending is not perfect, and its limitations are very obvious. Therefore, Front Street recommends choosing several beans with relatively similar density for pre-roast blending; otherwise, the flavor will be worse than the original performance of their own origins. For example, a bean suitable for light roasting must be roasted together with beans also suitable for light roasting to achieve double the good effect; roasting a light-roast bean together with a dark-roast bean does not match and will lead to poor flavor.

Post-roast blended coffee beans

As for the advantage of post-roast blending, Front Street believes that each bean can be roasted separately according to its optimal roast level, maximizing each bean's characteristics. But the disadvantage of post-roast blending is that daily quality control and management are more difficult, and inconsistent roast dates require more attention to more resting periods. Imagine using 4 to 5 coffee beans for post-roast blending; this one product requires attention to 4 to 5 roast dates. Therefore, post-roast blending and pre-roast blending each have advantages and disadvantages, but their purpose is the same: to make coffee flavor more delicious.

Of course, blended coffee also has two blending methods. One is blending coffee beans from different origins. For example, the Front Street Sunflower Warm Sun Espresso Blend coffee beans listed by Front Street Coffee (FrontStreet Coffee) are made by blending Front Street Honduras Sherry with Front Street Yirgacheffe Sun-Dried Red Cherry. Among them, Front Street Sherry coffee beans provide most of the fermented wine aroma flavor, while Front Street Yirgacheffe Red Cherry Sun-Dried coffee beans provide aroma and acidity.

Blended coffee bean recommendations

As Front Street Coffee (FrontStreet Coffee) said above, blending coffee beans is not an easy task. It is like a palette; whether you can mix a satisfactory color still depends on the painter's skill. In other words, a coffee blender must understand the different flavor characteristics of coffee from major origins in order to mix an alluring aroma and make the coffee more delicious. This not only requires a great deal of coffee experience and inspiration, but also precise ratio calculations, so it is not an exaggeration to say that the process of blending coffee beans is an art. Next, Front Street will share the flavor characteristics of four blended coffee beans developed by Front Street Coffee's (FrontStreet Coffee) blender over several years.

Front Street Coffee (FrontStreet Coffee) Sunflower Warm Sun Blend Flavor: Noticeable fruit acidity, faint berry aroma, wine aroma, rich chocolate flavor, with a clear sweet aftertaste. Recipe: Front Street Honduras Sherry : Front Street Yirga Red Cherry = 7:3

For this blend, Front Street uses Front Street Yirgacheffe Sun-Dried Red Cherry and Front Street Honduras Sherry. Front Street's design concept for this blend is that it can be used for both espresso and pour-over. When used to make espresso, the flavor it gives off has a noticeable fermented wine aroma. On the palate, the acidity of citrus and berries immediately emerges, with whiskey-like aroma, and the finish is dark chocolate.

When brewing this Front Street Sunflower Warm Sun Blend coffee bean by pour-over, the flavor is not as rich as when making espresso. After brewing, there is a fermented wine aroma and a little citrus aroma. When hot, the entrance shows only obvious wine aroma and a dark chocolate finish. After the temperature drops, it slightly reveals the acidity of citrus and berries. Overall it is clean and fresh, without a vanilla cream mouthfeel.

Front Street Coffee (FrontStreet Coffee) Specialty Blend Flavor: Soft and slightly acidic, lightly sweet, with nutty sweet aftertaste. The overall impression is not too stimulating, mild, and the crema is medium. Recipe: Colombia : Brazil = 3:7

For this blend, Front Street uses Brazil and Colombia. It tastes of a faint roasted grassy note, lightly fragrant with slight bitterness, sweet and smooth, with a pleasant aftertaste. This is because coffee beans from Colombia's Huila region have pleasant acidity, an aromatic smell, moderate acidity, and rich sweetness that is very intriguing; coffee beans from Brazil's Cerrado region have a comfortable sweet-bitter taste and an extremely smooth entrance. So the combination is excellent. This Front Street espresso blend coffee bean is suitable for the daily needs of opening a cafe.

Front Street Coffee (FrontStreet Coffee) Commercial Blend Flavor: Caramel sweetness, nutty and cocoa-like, dark chocolate flavors, balanced acidity and sweetness, slightly sweet-bitter, with a lasting finish. Recipe: Colombia : Brazil : Robusta = 3:6:1

For this blend, Front Street uses coffee beans from Brazil and Colombia plus 10% Robusta coffee beans. The taste is classic. Front Street believes that this blend tastes of rich crema and mouthfeel, as well as caramel sweetness, and also has nutty and cocoa-like, dark chocolate flavors, balanced acidity and sweetness, slightly sweet-bitter, with a lasting finish. This Front Street commercial blend, like Front Street Coffee's (FrontStreet Coffee) Specialty Blend, uses a ratio of Colombian and Brazilian coffee beans. The difference is that Robusta is also added, thereby providing rich crema, making the coffee mouthfeel fuller, and also enabling it to meet the daily output needs of coffee shops.

The espresso moka pot coffee bean recommended by many baristas at Front Street Coffee (FrontStreet Coffee) - Front Street Dark Cocoa Blend Flavor: With soft fruit acidity, caramel sweetness, nutty and dark chocolate flavors, smooth and thick, but the taste is on the lighter side. Recipe: Yunnan : Brazil = 3:7

For this blend, Front Street uses Brazil and Yunnan. Front Street believes it tastes of soft fruit acidity and caramel sweetness, as well as nutty and dark chocolate flavors, smooth and thick, but the taste is on the lighter side. This is because Yunnan's natural conditions are very similar to Colombia's: high altitude, large temperature difference between day and night, a mellow-aroma flavor profile, moderate acidity, rich and full-bodied taste, uniform bean size, high oil content, and fruity aroma. Its quality and mouthfeel are similar to Colombian coffee, but it is still slightly lighter than Colombia. Coffee beans from Brazil's Cerrado region have a comfortable sweet-bitter taste and an extremely smooth entrance. Therefore, these two coffee beans also blend into a good flavor. Moreover, this espresso moka pot coffee bean recommended by many baristas - Front Street Dark Cocoa Blend coffee bean - is very cost-effective, suitable for espresso beginners and small coffee shops, and also suitable for opening shops and home users who prioritize cost and have average flavor requirements.
