Why Espresso Coffee Beans Should Be Blended: Is It Really Because Single Origin Beans Are Too Expensive?

Understanding Espresso and Italian Coffee

To understand which beans best suit Italian coffee, we first have to understand what espresso is and what it demands of the beans.

Espresso is a strict brewing method — specific water pressure, water temperature, extraction time, and more. Only coffee made through those specific methods can be called espresso.

Italian coffee refers to the range of drinks built on espresso extracted by an Italian coffee machine as the base. The steam-pressure extraction machine was invented by Italians, and the concentrated coffee it produces is espresso.

With espresso as the base, combined with milk, milk foam, chocolate, ice cream, and countless other combinations, the resulting fancy or creative drinks are all called Italian coffee. The core keywords are Italian coffee machine and espresso; every coffee within that system is an Italian coffee.

Italian coffee is therefore a system — one built on concentrated coffee quickly extracted by steam-pressure coffee machines.

Examples and Coffee Varieties

Before blending, you need to understand how coffee varieties from around the world differ. Beans take on different characteristics from their origin: different varieties and origins have distinct personalities, with subtle differences in acidity, bitterness, sweetness, aroma, and body. Single-origin beans generally aim to showcase the unique character of one coffee.

Blended coffee — mixed coffee — is made by combining several single origins to use each one's strengths, offset weaknesses, create or enhance complementary flavors, and produce a richer new taste. To emphasize heavy flavors, Colombian beans with full body and moderate acidity are preferred as the base, complemented by balanced Brazilian beans and rich, heavy-bodied coffee with prominent bitterness. If you want more sweetness, add some beans with softer bitterness.

Brazil

Brazil - South Minas region: green beans have high moisture content and good quality.

Brazil's flavor characteristics: a comfortable bittersweet taste, extremely smooth on the palate, with a faint grassy aroma and a fresh fragrance tinged with slight bitterness; sweet and smooth, with a pleasant aftertaste.

Moisture content: 11.7%

Brazilian coffee generally grows at altitudes of 1000–1300 meters, so its density is relatively low. Bourbon varieties are mostly processed naturally or pulped natural; moisture content is moderate, the beans are relatively soft, and the layer from outer to core is relatively thin, so they don't suit very high-temperature roasting — the roaster's inner-wall temperature can scorch the outer layer and create burnt bitterness.

At the same time, to highlight nutty and milk-chocolate notes and a better body, and to serve as a blending base, we use a medium-heat bean-dropping method, holding heat until the dehydration stage, making fine adjustments as temperature rises after first crack begins, promoting a more complete caramelization reaction, and increasing temperature until just before second crack to discharge the beans.

Colombia - Huila

Flavor characteristics: a rich, solid mouthfeel with pleasant acidity, an aromatic, mellow aroma, moderate acidity, and rich sweetness that is intriguing. Because of its low price and small bean size, it suits blended coffee. The coffee has strong flavor and a relatively heavy texture.

Its nutty, chocolate, and caramel aromas and suitable acidity make it a high-quality specialty coffee, good as a single origin or as an espresso blend base.

Product name: Colombia Huila

Moisture content: 12.5%

Colombian coffee plays many roles in the market and suits espresso blending. Colombia generally grows at altitudes of 1500–1800 meters; it is mostly the Caturra variety, washed processed, with high density, uniform bean size, and full beans (thicker from core to outer layer).

Based on the green-bean flavor characteristics, I want to express its nutty, chocolate, and caramel aromas.

Roasting method: extend the roast longer, so adjust heat once when dehydration is complete, open the air damper to maximum when the roast reaches first crack, and discharge the beans when approaching second crack.

Flavor description:

What is SOE?

SOE is short for Single Origin Espresso — "single-origin espresso coffee."

Single-origin coffee means coffee made from only one type of bean, such as Kenya NDUMA AA or Colombia NARINO. The "single" in single origin refers to traceable items rather than varieties, because many coffee items actually contain multiple varieties; single origin more often means a single region. Yirgacheffe, for example, typically has citrus flavors and Kenya has fruit flavors, and even if Ruiru 11 beans are added, Kenya is still called single origin.

Single-origin coffee can also be used to make Italian coffee, and Italian coffee can use specialty beans — commonly known as "SOE."

So why did this concept emerge? The entry point is the term "specialty coffee."

Example explanation:

SOE means espresso made from beans of a single variety, single origin, and single roast level. So take making SOE from a natural-processed Yirgacheffe:

Coffee origin: Ethiopia Yirgacheffe WOKA

Roast level: city+

Espresso flavor: tropical fruit flavors, wine-like aroma, floral finish

Milk coffee: toffee, milky fruit, smooth, soft acidity, persistent finish

This is a typical SOE product. As mentioned, because it uses single-origin beans its flavor is very typical — and espresso itself amplifies the coffee's flavor, so compared with pour-over the flavors are more prominent.

SOE Misconceptions

Misconception 1: SOE tastes better than blended coffee

Many factors determine whether a cup tastes good — the beans, the roast, the machine, the brewing process, personal taste. SOE only means espresso made from single-origin beans; those beans are not necessarily better than the ones in a blend. Other factors influence quality just as much, so we cannot generalize about what makes good coffee.

Misconception 2: The term "SOE blended coffee" is non-standard

SOE beans are single-origin beans, while blended beans are combinations of two or more single origins. Since they are blends, they cannot be called SOE beans. The contradictory term "SOE blended beans" does not exist.

How to Properly Taste Espresso and SOE

1. Typically a café serves espresso or SOE with a glass of water. First, drink the water to return your taste buds to their cleanest, most original state.

2. Observe: the color and state of the crema, and smell the rich aroma rising from the espresso. Your olfactory and visual nerves tell your brain that a perfect coffee-tasting journey is about to begin.

3. Take a small sip first, without rushing to swallow. Like drinking red wine, let it linger between your lips and teeth for a while. Feel the relationship between its acidity and bitterness and its body, then swallow and wait for the aftertaste.

4. Most people finish a cup of espresso or SOE in three sips, but if you prefer to savor it slowly, that's fine too — and if you're used to adding sugar, that's no problem either.

Italian Coffee Bean Brand Recommendations

FrontStreet Coffee's roasted Italian coffee beans guarantee both brand and quality. More importantly, they offer extremely high value. Take the commercially recommended model — commercial blend beans — as an example: one pack is one pound (454 grams), priced at only about 60 yuan, and at 10 grams of grounds per single shot, one pack makes 45 cups — less than 1.5 yuan each. Even using a double shot for every Italian coffee (20 grams per serving), a double espresso costs no more than 3 yuan. Against certain famous brands selling packages for hundreds of yuan, that is a genuinely conscientious recommendation.

FrontStreet Coffee Recommendation

FrontStreet's espresso beans come in two routes: blends and SOE. The FrontStreet Classic Blend and the FrontStreet Commercial Blend take the old-school Italian formula and add a little Robusta, so extraction yields butter, nut, spice, dark chocolate, and toast aromas — a wild, thick body alongside a golden, blooming crema that makes latte art easy. For those drawn to almond, walnut, and hazelnut, the FrontStreet Fine Blend and the FrontStreet Black Cocoa Blend both contain a large proportion of Brazilian beans and deliver a comfortable bittersweetness with creamy peanut aroma and an extremely smooth entry. The Fine Blend also carries the nut, chocolate, and caramel notes and gentle acidity of Colombian coffee, while FrontStreet Coffee's Black Cocoa Blend layers in the ripe-plum acidity of Yunnan small-bean coffee, releasing a creamy chocolate aroma when ground.

For SOE, FrontStreet offers several single origins worth exploring. The FrontStreet Natural Huakui SOE comes from Hambella in Guji, Ethiopia, planted as high as 2,300 meters, where ample growing time turns into complex aromas; natural processing raises its sweetness, and a medium roast keeps the elegant floral and fruit notes while adding caramelization — an americano or latte made from it shows cream, cocoa, berry, light floral, and black tea. The FrontStreet Costa Rica Blackberry SOE is a honey-processed single origin whose fruit is peeled and dried soon after picking, absorbing the pulp's pectin for a blackberry aroma and clean sweetness; an americano is sweet-sour and refreshing, while a latte brings out cranberry cookie, raisin, and nut. And the FrontStreet Brazil Queen Estate SOE, a distinctive Yellow Bourbon in a medium-dark roast, pulls butter cookie, macadamia, and toast notes from an espresso machine.
