Should you pick blended coffee beans or single-origin for espresso?

Both work, but they aim at different results. Single-origin beans highlight the terroir and personality of one origin, while blended coffee beans are built for stability and balance in the cup. Beans used for pour-over can also be pulled as espresso, and blends can be brewed as pour-over, though the grind changes.

Freshness matters before anything else. Look for a clearly marked roast date rather than an expiration date, choose roasters focused on fresh roasting, and check for a one-way exhaust valve on the bag, the small button that releases carbon dioxide. Front Street Coffee also weighs SOE roasting and bean selection in its guidance.

In the world of espresso, the choice of coffee beans often determines the foundation of a cup. The coffee beans commonly found on the market are broadly divided into two categories: single-origin and blends. The former emphasizes the terroir and personality of a specific origin, while the latter pursues stability and balance of flavor. Many people wonder: can single-origin beans used for pour-over be directly used to make espresso? And can blended beans be used for pour-over? From the perspective of Front Street Coffee, this article sorts out the differences between single-origin beans and blended beans, the impact of freshness on flavor, and the considerations of SOE in bean selection and roasting. It also shares the specific flavors of products such as Front Street Warm Sun Blend, helping coffee enthusiasts clarify their thinking and find the bean suitable for their own espresso recipe.

Under the wave of specialty coffee, more and more people are falling in love with single-origin coffee. The market has consequently formed two major categories of coffee beans: one is single-origin beans, and the other is blended beans. Single-origin beans usually appear in the context of pour-over coffee, though quite a few specialty coffee shops also use them to extract espresso. Blended beans, on the other hand, serve espresso more often, and their value lies in keeping the flavor of espresso stable. This time, Front Street will talk about exactly where the differences between single-origin beans and blended beans lie.

Before expanding on the topic of single-origin beans and blended beans , Front Street Coffee always puts one thing first—the freshness of the coffee beans.

When choosing, whether single-origin or blended, you should look for products with a clearly marked roast date (not an expiration date or shelf life), and choose professional roasters with a good brand reputation that focus on fresh roasting. In addition, coffee packaging of acceptable quality generally comes with a "one-way exhaust valve," that is, the small button-like hole on the upper part of the bag, whose function is to release the carbon dioxide naturally emitted by the coffee beans.

Bring the one-way exhaust valve close to your nose and gently squeeze the bean bag to let the air inside escape and take a sniff. If a rich, pleasant coffee aroma rushes out, it means the freshness is still there; conversely, if the aroma is faint, or even carries an oily, stale odor, then this bag of beans has most likely already oxidized and gone off, and is not recommended for purchase. Every bag of coffee beans sold by Front Street Coffee uses packaging with a one-way exhaust valve, striving to ensure that it is still in the freshest state when it reaches enthusiasts. Front Street values fresh roasting so much because, as time passes, once more than fifty days have passed since roasting was completed, the aroma has basically dissipated. So is fresher always better? Not necessarily. In the one or two days right after roasting, the aroma has not yet fully stabilized.

Single-Origin Coffee Beans

So-called single-origin coffee refers to coffee from a specific origin, specific producing region, or specific estate. It carries a special flavor that cannot be replicated and can reflect the local terroir. For example, Front Street Coffee's Huakui coffee comes from Front Street Huakui coffee beans produced at the Buku processing station in the Guji region of Ethiopia.

The reason single-origin coffee is special is that, during purchasing, the quality of green beans can be checked batch by batch, or even bean by bean. This process can be compared to picking strawberries: "Imagine you can only pick a small bowl of strawberries that are at peak ripeness, sweetest in taste, and softest. Single-origin coffee is the same. Because quality is monitored throughout the entire process, you can taste more sweetness, floral notes, and syrupy flavors in the cup, while avoiding defects and negative mouthfeel, so single-origin coffee is also priced relatively higher. The roast level of single-origin coffee beans varies widely, and different roast levels will make the same single-origin bean present completely different flavor directions.

Blended Coffee Beans

Blended beans are also called mixed coffee, espresso coffee beans . The method is to mix multiple single-origin coffee beans together so that each of their strengths can be brought into play. Blended beans are composed of coffee beans from different origins, with the aim of achieving a more balanced taste. For example, if one bean is smooth in body but lacks aroma, another bean full of aroma can be added so that their advantages complement each other, either complementing or strengthening each other in taste, ultimately creating a new flavor with richer layers. Sometimes the green beans are mixed first and then roasted, which is called pre-roast blending; sometimes they are roasted separately and then mixed, which is called post-roast blending. Whether pre-mixing green beans or blending after separate roasting depends on the characteristics of the coffees in the recipe, and both approaches are valid. The advantage of blending after roasting is that each bean can receive a different degree of roasting, allowing each component to show its best state.

Front Street Coffee would like to remind you of one point: before blending, you must first understand what flavors the coffees of various producing regions and varieties around the world each have. Beans have their own characteristics when divided by origin, which requires the roaster to have a relatively clear grasp of the characteristics of coffee beans from multiple producing regions in order to adjust the roasting curve accordingly. Different coffee beans have different personalities due to different varieties and origins, with subtle differences in acidity, bitterness, sweetness, aroma, body, and so on, while single-origin coffee beans often focus more on expressing the unique personality of a certain type of coffee.

Is single-origin espresso (SOE) just using pour-over beans to make espresso?

Conceptually, making espresso from single-origin coffee beans used for pour-over is indeed SOE, "single origin espresso," but in actual operation it is far from as simple as imagined.

Compared with traditional blended espresso, SOE is supposed to be an espresso with a more prominent flavor. This characteristic determines that when selecting beans for SOE, one should try to choose coffee beans with high flavor recognition and sufficient intensity; if beans with relatively weak flavor intensity are chosen to make SOE, the resulting espresso will appear thin and weak. Just imagine, such an SOE that has neither distinctive features nor the balance and stability advantages of blended beans would not be worth the loss.

Second, the roast level should be neither too dark nor too light. A darker roast will greatly grind away the flavor of the origin, while a lighter roast will cause the coffee machine to further amplify the acidity brought by light roasting under high pressure, and the espresso can easily become so sharply acidic that it is hard to swallow; at the same time, a lighter roast also makes the bean texture harder, making under-extraction more likely. Whether it is grinding away the flavor of the origin or causing imbalance through sharp acidity, both deviate from the original intention of highlighting the flavor of a single origin, so the curve for making SOE from the same bean and the curve for making pour-over should be two different roasting curves.

Can blended coffee beans be used to make pour-over coffee?

Blend refers to a mixture of two or more different coffee beans. Many people's stereotyped impression of blends is still stuck on the blended beans used in traditional espresso . But in fact, a blend is not equal to espresso coffee beans. A blend is merely the concept of mixing different coffee beans for a certain purpose, and is not exclusive to espresso, that is, blended beans = espresso coffee beans. So pour-over is only an extraction method, and blending is only a type of coffee bean; the two do not determine each other. Can blended coffee beans be used to make pour-over? The answer is yes.

Front Street Coffee's Front Street Espresso Blend Coffee Beans:

Mixing coffee beans from different producing regions to make blended beans was also a very common blending approach in the past.

1. Stable flavor

Coffee beans are ultimately an agricultural product. Even for the same bean, the flavor will fluctuate from year to year. Mixing several coffee beans together can solve this problem well, keeping the taste basically consistent each year.

2. Balanced taste

Espresso machines have a characteristic: they amplify the most prominent flavor of the coffee beans, so we almost never use a single variety of coffee to make Espresso. Otherwise, if that bean is biased toward bitterness, the Espresso made will be unusually bitter; if it is biased toward acidity, it will be excessively sour. Therefore, blending is needed to balance the various tastes.

Front Street Warm Sun Blend, roasted by Front Street Coffee itself, is made from a blend of two producing regions: Honduras and Ethiopia Yirgacheffe. Front Street Honduras Sherry Coffee Bean brings this coffee a rich whiskey aroma and a finish of liqueur chocolate, with a full aroma. Front Street Sun-Dried Red Cherry brings fermentation notes and berry aroma, smooth on the palate. Flavor characteristics: obvious fruity acidity, a faint berry aroma lingering, rich wine aroma and chocolate flavor, and a comfortable sweet aftertaste.

Blended beans for pour-over single-origin coffee:

This is done by blending different varieties of coffee beans from the same producing region or the same origin. As the name suggests, it is a mixed bean obtained by blending different varieties, such as a very popular Front Street Panama Butterfly Geisha Blend, known for blending about 70% Geisha variety with 30% Caturra and Catuai; and a recently launched Front Street Costa Rica Mirazu Estate Geisha Blend, blending half Geisha variety and half SL28, ET47, and Maico.

However, Front Street believes that calling coffee beans made by mixing different varieties a blend is only to highlight one of the varieties, and is not a blend in the traditional sense.

Interestingly, if coffee beans made by mixing different varieties are also counted as blends, then most of the coffee beans we commonly see would all become blends, such as the common Kenya coffee that often mixes SL28 and SL34, Ethiopia's local heirloom varieties, and so on.
