The Basics of Blending Coffee

Coffee Blending Basics

Coffee blending lets you combine beans from different origins to create a cup that matches your personal taste. Learning the basics of coffee tasting can help you identify the flavors you want in a blend. Whether you want more body, brighter acidity, or richer chocolate notes, blending gives you complete control.  

Well, have you ever sipped a Costa Rican coffee and wished that it had just a little more body and richness to it? Do you love the deep, rich notes of a traditional Sulawesi but miss the bright citrus acidity of a Kenyan coffee? Blending single-origin coffees lets you create a cup that matches your preferred flavor profile.

Roasters blend coffee to improve consistency, reduce costs, or create unique flavor profiles. Specialty roasters focus primarily on developing distinctive tastes.

Economically, blending coffees makes sense for large commercial roasters, who frequently combine cheaper coffees with more expensive specialty beans to reduce the cost of their offerings. Consistency is also of particular importance to large roasters and distributors. Customers expect a brand of coffee to taste the same from one cup to the next. Coffee varies by farm, region, and harvest. Blending helps maintain a consistent flavor. The result is often a bland (though they’ll call it balanced) cup of coffee with no predominant flavor notes. Specialty roasters also value consistency, but their main goal is creating unique flavors. This is where the true artistry of coffee blending lies; in discovering and melding the unique qualities of two or more coffees to create a new coffee that is more than the sum of its parts.

How to Choose Blends

Even if you don’t want to create your own blends, it’s helpful to know what flavors you like and how they work together. Many specialty roasters list the origins of the coffees they incorporate into their blends. Understanding coffee origins helps you choose blends with confidence.

Coffee Blending Recipes

If you frequent coffee forums and discussion groups, you’ll find dozens of “recipes” for blending coffee, especially for espresso. Consider trying these blends to get a feel for coffee blending before devising your own blends.

1. Mocha-Java: A classic combination that may be one of the oldest blends known. One-third Yemen Mocha to two-thirds Sumatra Mandheling, all at Full City roast, for a smooth, rich coffee with full body and deep cocoa flavor.

2. Black and Tan: Blend equal proportions of dark-roasted Colombian and light-roasted Colombian to take advantage of the qualities brought out at different roast levels. This approach works with other single-origin coffees as well.

3. Filter Drip Melange: Blend 60% Colombian at Full City with 40% Kenya at City for a drip coffee that has balanced body, bittersweet flavors and bright acidity.

How to Blend Coffee for Espresso

To Robusta or not to Robusta, that is the question. At least, that’s one of the burning questions facing coffee roasters who offer espresso blends. The traditional wisdom is that coffee blends made expressly for espresso benefit from a bit of Robusta, mainly because it provides bite, bitterness and crema. Many artisan roasters disagree with this, and point out that most dry-processed coffees will provide all one needs in terms of these qualities. If you want to attempt your own espresso blends, you might start by sampling the blends offered by the best specialty roasters and then trying to approximate them.

How to Blend Coffee at Home

Don’t let the idea of creating your own signature blend intimidate you. Don't overcomplicate the process. Focus on experimenting and enjoying the results. The best advice of all is to have fun with it; approach it from the perspective of an artist experimenting with a new medium.

In The Art and Craft of Coffee, Kevin Sinott offers this novel approach to devising your own blends.

1. Start with a base coffee that you like, brewed the way you typically brew your coffee.

2. Think about what you would add to make it “better.” More body? A hint of cocoa? More sweetness? Choose a second coffee that has those qualities.

3. If you’re really daring, choose a third coffee and a fourth—up to five coffees. Beyond that, most experts agree that you’ll start canceling out the benefits of blending.

4. Brew a cup of each coffee and transfer them to insulated, covered vessels to keep the coffee hot.

5. Once you have all of your coffee samples brewed, start mixing and keep a running list of the ratios you use. For example, pour 3 ounces of one coffee into a cup and add 1 ounce of a second coffee into the same cup. Taste. Adjust the proportions to highlight the qualities you want to accent.

6. When you get a blend ratio you like, mix roasted beans in the same ratio and brew to see if it retains the qualities that set it apart.

Coffee blending combines beans from different origins to create balanced, unique flavors. Experiment with different ratios until you find your ideal cup.

Frequently Asked Questions About Coffee Blending

What is Coffee Blending?

Coffee blending is the process of combining beans from different origins to create a balanced flavor profile. By mixing coffees with complementary characteristics, you can customize body, acidity, sweetness, and aroma to match your preferences.

Why do coffee roasters blend coffee?

Roasters blend coffee for three main reasons: to create a consistent flavor, develop a unique signature profile, or reduce production costs. Specialty roasters typically focus on crafting distinctive flavors rather than lowering costs.

Which coffee beans work well together?

Beans with complementary flavors often produce the best results. For example, a bright, citrus-forward coffee can balance another with chocolate notes and a fuller body.
