A Complete Guide to Coffee Varieties

From the highlands of Ethiopia to your local Czech roastery, understanding coffee beans is the key to a better cup.

Coffee is one of the most consumed beverages on the planet, and the Czech Republic is no exception. Czechs drink an estimated 160 liters of coffee per person each year, placing the country among the top consumers in Europe. Yet many coffee drinkers know surprisingly little about the beans that end up in their cup. This guide aims to change that.

Arabica: The World's Favorite

Coffea arabica accounts for roughly 60 to 70 percent of global coffee production. Originating in the forests of southwestern Ethiopia, Arabica is prized for its complex flavor profile, which can include notes of fruit, sugar, and floral undertones. The beans tend to be oval-shaped with a pronounced center crease.

Arabica plants thrive at higher altitudes, typically between 600 and 2,000 meters above sea level. They are more delicate than their Robusta counterparts and susceptible to pests and diseases, which contributes to their higher market price.

Key Arabica Sub-Varieties

Robusta: The Resilient Bean

Coffea canephora, commonly known as Robusta, makes up most of the remaining global production. The name itself hints at the plant's hardiness: it can grow at lower altitudes, resists many common coffee diseases, and produces higher yields per hectare.

In terms of taste, Robusta beans are generally stronger and more bitter than Arabica. They contain nearly double the caffeine content, which contributes to a harsher, more full-bodied cup. While specialty Robusta does exist, the majority of Robusta production goes into instant coffee and espresso blends, where it adds body and a thick crema.

In the Czech Republic, you will find Robusta primarily in traditional cafe blends and supermarket brands. However, several Czech roasters are beginning to source high-quality Robusta from farms in Vietnam and India that are experimenting with improved processing methods.

Liberica and Excelsa

Beyond Arabica and Robusta, two other species deserve mention. Coffea liberica produces large, asymmetric beans with a distinctive smoky, woody flavor. It accounts for a very small percentage of global production, mostly in the Philippines and Malaysia.

Excelsa, now classified as a variety of Liberica, is grown primarily in Southeast Asia. It offers a tart, fruity profile that some roasters use to add complexity to blends. These beans are quite rare in the Czech market, but adventurous drinkers can occasionally find them through specialty importers.

Understanding Single Origin vs. Blends

When shopping for coffee in the Czech Republic, you will encounter two broad categories: single-origin and blends.

Single-origin coffee comes from one specific region, farm, or lot. It allows you to taste the terroir, meaning the unique characteristics imparted by the soil, altitude, and climate of where the coffee was grown. A single-origin Ethiopian Yirgacheffe, for example, will taste markedly different from a Colombian Huila.

Blends combine beans from multiple origins to achieve a consistent, balanced flavor profile. Many Prague cafes create their own signature blends, mixing beans from different regions to complement each other. A well-crafted blend can offer more complexity than any single component on its own.

A good starting point is to try single-origin coffees from three different regions, such as Ethiopia, Colombia, and Indonesia. This gives you a clear sense of how geography shapes flavor.

Roast Levels and Their Effect on Flavor

The way coffee beans are roasted has a profound impact on the final taste:

Understanding coffee varieties is a journey, not a destination. The more you taste, the better you understand your own preferences. Start with this guide, experiment with different beans, and do not be afraid to step outside your comfort zone.
