Mariam Erin Pinza October 2024

Robusta beans often carries a negative reputation in thecoffee world, and it's easy to see why when you dig into the details. Whilehundreds of coffee species exist, only Arabica and Robusta dominate thecommercial landscape. Arabica beans is generally the higher-quality choice, whileRobusta—making up around 30 to 40% of global coffee production—gets a bad rapfor its more robust, less delicate flavor. So, is Robusta as inferior as peoplethink, or could it taste better under the right conditions?

Arabica vs. Robusta: The Basics

Before discussing how Robusta
shows signs of potential, let's examine the differences to help you decide which is better for your brew.

Difference between Arabica and Robusta

1. Taste and Caffeine Content

Arabica is often favored for its smoother, sweeter flavor with fruity and sugary notes. On the other hand, Robusta coffee flavor tends to be more bitter, sometimes even described as having a burnt or rubbery taste—not exactly what you'd want to wake up to in your morning cup. The reason? Robusta packs a much higher caffeine punch—about 2.7% compared to Arabica's 1.5%. While that extra caffeine is excellent for a solid wake-up call, it contributes to the brew's bitterness.
Robusta's more intense taste isn't just from the caffeine. The coffee beans contain more chlorogenic acids (CGAs), contributing to flavor and health benefits. These acids give Robusta a more pungent, bitter taste, with 7-10% CGA levels compared to Arabica's 5.5-8%.

2. Price, Farming, and Usage

If you're budget-conscious, Robusta production might be tempting since it's about half the price of Arabica on the commodity market. Thanks to its higher caffeine content, which acts as a natural insect repellent.
Robusta coffee plant is more accessible to grow, yields higher quantities, and is more resistant to pests. For these reasons, many roasters use Robusta in blends to cut costs, although this often comes at the expense of coffee flavor.
Nowadays, Robusta is mainly used in instant coffee or as a filler in some espresso blends, where it's valued for producing a thick crema. However, if flavor is your top priority, you might lean towards Arabica for your espresso shots.

What is Specialty Arabica?

Not all Arabica coffee beans qualifies as specialty grade, even when labeled "100% Arabica." Specialty coffee must score 80 or above on a 100-point scale, graded by Licensed Arabica Q-Graders who rigorously assess factors like flavor, aroma, and aftertaste. This coffee goes through a careful journey, from hand-picking and defect sorting to mindful roasting, ensuring top-tier quality and traceability. Store-bought Arabica often lacks care and transparency, producing over-roasted beans with a muted, less complex flavor.

Specialty coffee Arabica stands out for its bright, unique flavor profiles that can surprise even seasoned drinkers. Unlike mass-produced Arabica's bitterness or flat taste, specialty beans deliver a dynamic and enjoyable experience. Investing in specialty-grade coffee ensures a richer, more flavorful cup for those looking to elevate their coffee game.

What is Fine, Robusta?

Despite its bad reputation and undeniably natural resilience against climate change more than Arabica, high-end specialty Robusta can rival or surpass lower-end Arabica coffee flavor in taste. Specialty Robusta is rare, but it's becoming more recognized for its potential. In 2010, the Coffee Quality Institute (CQI) launched a program for Robusta following their successful Q-Grader certification for Arabica coffee quality. This initiative allowed coffee professionals to become licensed "Q-Robusta Graders," marking a significant step in recognizing and improving the quality of Robusta coffee. While Arabica has spent centuries of time and resources perfecting its quality through selective breeding, production, processing, roasting, and brewing techniques, Robusta has only recently begun to receive the same level of attention. As more focus is placed on high-quality Robusta, its potential to create decadent, flavorful cups of coffee is being explored.

Final Thoughts: Can Robusta Coffee Taste Better in the Future?

Choosing between Arabica and Robusta boils down to personal preference. Arabica coffee characteristics offers a sweeter, smoother experience, while Robusta provides a bold caffeine kick and a higher body, bitter flavor. But as the specialty coffee world embraces Robusta's unique qualities, we might soon see a shift. With programs like CQI's Specialty Robusta Grading pushing for higher standards, Robusta could evolve into a coffee that surprises even the most discerning palates.

So, whether you're a fan of fruity, delicate brews or prefer a strong cup that gets you moving in the morning, understanding these differences will help you pick the perfect coffee. And who knows? Soon, we might all enjoy a cup of high-end Robusta that rivals even the finest Arabica.
