FrontStreet Coffee's Espresso Recipe Guide: How to Blend Espresso? What Are the Tips for Espresso Blend Beans?

Introduction

Blend coffee, also called mixed coffee, combines several single-origin beans to make the most of each one's character. The goal is a more balanced flavor profile. If one bean is smooth but lacks aroma, for instance, another with a rich aroma can be added so the two cover each other's weaknesses and create — or intensify — complementary flavors for a fuller new taste. Sometimes the beans are mixed before roasting, which is called raw blending; sometimes they are mixed after roasting, which is called roasted blending.

Whether you pre-mix green beans or blend individually after roasting, both approaches depend on the character of the coffees in the recipe, and both are acceptable. Mixing after roasting allows each component to be roasted to a different degree so that every bean performs at its best.

Before blending, you need to understand how varieties taste around the world, because beans carry distinct character according to origin. Different varieties and origins give beans distinct personalities, with subtle differences in acidity, bitterness, sweetness, aroma, and body. Single-origin beans tend to emphasize the character of one particular coffee. Blends are used most often for espresso-based drinks — Espresso, Americano, Latte, Cappuccino — where they provide a more balanced, smoother, more stable flavor that appeals to a wider audience.

The main reasons for blending are:

1. Stable Flavor

Coffee is an agricultural product, so even the same bean tastes different from year to year. Mixing several beans together solves this neatly, keeping the taste broadly consistent year after year.

2. Balanced Taste

An espresso machine amplifies whatever flavor is most prominent in the beans, which is why single-variety coffee is almost never used for espresso on its own. A bitter bean would yield a punishingly bitter shot; an acidic bean, a sharply acidic one. Blending is how we balance those flavors.

Blending is never simple addition. It is an attempt to have different beans cover one another's weaknesses through the blender's own understanding of coffee flavor, producing a blend with exceptional character.

The Rise of Single Origin Espresso (SOE)

SOE stands for Single Origin Espresso and has become popular recently. It is not necessarily equivalent to specialty coffee, but choosing a single-origin bean with an easily recognizable flavor can produce a distinctive espresso — the classic citrus of Yirgacheffe, say, or the tropical fruit of Kenya. Because espresso amplifies flavor, those notes stand out more than they would in a pour-over. For all that SOE performs impressively, coming from a single origin also makes its weaknesses easy to amplify, so roasting and grind size heavily affect the cup; it is not automatically better than a blend.

How Do We Blend?

(1) FrontStreet Coffee's Premium Blend:

Colombia : Brazil, ratio 3:7;

Colombia Huila Region

Located in southwestern Colombia, Huila is one of the country's main coffee-growing areas. Colombian coffee generally grows at 1,500–1,800 meters, mostly from Bourbon and Caturra varieties, using washed processing. The beans are dense, uniform in size, and full in shape (thicker from bean core to surface). Because famous growing areas are scattered throughout Huila, the names of various small districts have become brand names in circulation. Cultivation conditions are good, but the infrastructure of the farms and their surroundings is not well developed — green-bean drying equipment and washed-processing facilities are still incomplete, which is a shame. Coffee from Huila has strong flavor and heavier texture; its nutty, chocolate, and caramel aromas, with suitable acidity, make it a high-end specialty coffee.

Flavor characteristics: A rich, solid taste with pleasant acidity, an aromatic profile, moderate acidity, and a rich, intriguing sweetness. Because of its low price and small beans, it suits blending. The coffee has strong flavor and heavier texture; its nutty, chocolate, and caramel aromas with suitable acidity rank it as high-end specialty coffee, suitable as a single origin or as an espresso blending base.

Brazil Cerrado Region

Brazilian coffee generally grows at 1,000–1,300 meters, so its density is relatively low. Mostly Bourbon, using natural processing. With moderate moisture content, a softer bean texture, and a thinner distance from surface to core, it should not be roasted at too high a temperature — the inner wall of the roaster would scorch the bean surface and create burnt bitterness.

At the same time, to express the nuts, milk chocolate, and good body and to serve as a blending base, we insert at medium heat, hold the heat through the dehydration stage, make fine adjustments as the temperature rises after first crack begins to promote a more complete caramelization, and can drop the beans as the temperature approaches second crack.

Flavor characteristics: A comfortable bittersweet taste, extremely smooth on entry, with a light grassy aroma, fresh and slightly bitter, sweet and smooth, and a refreshing finish.

Blended flavor: Sweet and aromatic. Roasted medium-dark, it pulls an espresso with soft, slight acidity, clear sweetness, and a nutty finish — overall not too stimulating, balanced, with moderate crema, meeting the daily needs of a coffee shop.

(2) FrontStreet Coffee's Commercial Espresso Blend:

Colombia : Brazil : Robusta, ratio 3:6:1, raw blending;

[Robusta] beans resist disease and pests well and yield heavily. They are usually less acidic than Arabica, often with a slight woody aroma. At 2.2% caffeine they exceed Arabica's 1.2%, and their chlorogenic acid content is higher too, making them quite bitter. They are usually reserved for commercial beans and cost less than Arabica.

Taken on their own, commercial beans make coffee far inferior to specialty beans. Generally they are chosen for blending, and through blending an excellent-tasting coffee can still be produced, suitable for latte, cappuccino, and other espresso drinks. Because of the Robusta, our commercial espresso blend has richer crema and a classic taste, with caramel sweetness and nut, cocoa, and dark-chocolate notes — balanced sweet and sour, slightly bittersweet, with a persistent finish, well suited to daily café production.

(3) FrontStreet Coffee's Basic Espresso Blend:

Yunnan AA : Brazil, ratio 3:7, roasted blending;

Our Yunnan AA is [Typica], the oldest native variety from Ethiopia, originating in southeastern Ethiopia and Sudan. All Arabica varieties descend from Typica. Its top leaves are copper-colored, which is why it is called red-topped coffee; the flavor is elegant but the plant is weak, with poor disease resistance, susceptibility to leaf rust, and low yield. Typica has four slender branches in a spreading posture with a tilt angle of 50–70 degrees. The opposite leaves are long and elliptical with smooth surfaces, the terminal branches are long, there are few branches, and white flowers grow at the base where the petioles meet the branches. Mature cherries look like cherries — bright red.

It needs more shade when planted and bears a harvest only about every two years. Yunnan's excellent geography and climate give coffee good growing conditions, with planting areas in Lincang, Baoshan, Simao, Xishuangbanna, Dehong, and elsewhere. Yunnan's natural conditions closely resemble Colombia's, with high altitude and a large day-to-night temperature difference. The flavor is mellow and aromatic, with moderate acidity, a rich and rounded taste, uniform particles, high oil content, and fruit aroma — its quality and taste are similar to Colombian coffee.

Blended flavor: Soft fruit acidity with caramel sweetness, nut, and dark-chocolate flavors, smooth and viscous, though the taste is rather light. This cost-effective espresso blend suits shop and home users who prioritize cost and have general flavor requirements.

When blending, there should be a clear primary and secondary distinction so the result tastes more interesting than a single origin. Before writing a blending plan, first imagine suitable combinations, then blend and roast accordingly, and settle on the best plan through cupping and later adjustment. Hope this helps.

FrontStreet Coffee Recommendation
