How Espresso Led to Lower-Quality Coffee Beans

Last year marked the darkest period in recent coffee market history. The global coffee trade—second only to oil in futures volume—saw prices plunge to a 30-year low. According to The New York Times, the entire industry faced its biggest crisis ever, driven by oversupply and collapsing demand. For anyone watching specialty coffee, the downward spiral wasn’t just about bad weather or bad luck—it was tied to the rise of espresso.

In short: yes, espresso’s global dominance played a major role in lowering coffee bean quality. To create consistent, affordable blends, the industry increasingly relied on lower-grade beans, especially robusta, while cutting back on premium arabicas like Colombian. This shift hurt both prices and production of high-quality beans worldwide.

Espresso and the Birth of Blended Coffee

Espresso, as a brewing method, relies on a specific mix of beans—often from multiple origins, varieties, and roast levels. Most commercial espresso is not a single-origin drink but a blend, carefully crafted to produce a balanced shot with crema and body. Over time, the industry moved toward creating what the centennial publication Tea & Coffee Trade Journal called “mysterious blended aromas.” These blends are engineered not to highlight any single bean’s character, but to achieve a uniform taste profile across batches. To meet that need, roasters frequently include lower-cost, lower-quality beans in the mix.

The Global Shift: Robusta Up, Arabica Down

This blending approach had major consequences for global production. To meet the demand for cheaper components in espresso blends, Vietnam ramped up cultivation of robusta—the lower-grade, higher-yield coffee bean that’s easier and less expensive to grow. At the same time, Colombia, historically one of the world’s top producers of premium arabica (including the famed Colombian coffee), saw its output drop by half. The result? By last year, Vietnam had overtaken Colombia to become the world’s second-largest coffee bean producer. But this boom came at a cost: the overall market price of coffee plummeted, with high-quality beans taking the hardest hit.

Why Quality Suffered Under Market Pressures

The espresso-driven demand for consistency and low cost reshaped coffee growing priorities. Unlike specialty roasters who focus on origin and processing, large coffee chains and mass-market roasters prioritize volume, price stability, and flavor uniformity. In the era of espresso blends, profit margins mattered more than terroir, tradition, or traceability. That shift incentivized the use of robusta or low-grade arabica in blends, further suppressing demand for premium beans and discouraging investment in high-quality cultivation. The result was a race to the bottom in terms of both price and quality.

Crema, Roast, and the Role of Bean Type

Espresso’s signature crema—a creamy, reddish-brown foam atop a well-pulled shot—is a product of high pressure, fresh coffee, and proper roast level. Crema forms when water under pressure emulsifies coffee oils, mixes with carbon dioxide from freshly roasted beans, and traps tiny air bubbles. The more oil and CO₂ available, the thicker and more stable the crema. Generally, robusta beans produce more crema due to their higher natural oil content and darker roast profiles, which is one reason they’re often included in commercial espresso blends. However, that crema often masks bitter, flat flavors compared to the brighter, more complex profiles of high-grade arabicas.

Frequently Asked Questions

Did espresso cause the coffee price crash?

Espresso didn’t single-handedly cause the crash, but its global popularity drove demand for low-cost, mixed blends. This incentivized the use of cheaper robusta beans and reduced demand for premium arabicas like Colombian, contributing to oversupply and a 30-year low in global coffee prices.

Why did Vietnam become the second-largest coffee producer?

Vietnam increased production of robusta beans to meet the demand for cheaper espresso blends. With higher yields and lower production costs, Vietnam overtook Colombia, which cut its output by half as demand for its premium arabica dropped.

Are robusta beans always lower quality?

Robusta beans are generally considered lower grade due to their stronger, harsher flavor and higher bitterness. However, they have more natural oils and caffeine, produce more crema, and are more disease-resistant, making them common in commercial espresso blends where cost and consistency are prioritized.

Why did Colombian coffee production fall?

Colombia, a major producer of premium arabica, reduced output by half as global demand shifted toward cheaper blends. With less appetite for higher-priced, single-origin beans, Colombian farmers faced falling revenues and scaled back production.

Does crema mean better espresso?

Not necessarily. While crema is a sign of proper pressure and fresh beans, it can also come from lower-quality robusta beans. A thick crema doesn’t guarantee a complex or high-quality flavor—many commercial blends use robusta for crema at the expense of taste.

What’s the difference between arabica and robusta in espresso?

Arabica offers more delicate, nuanced flavors with higher acidity and sweetness, while robusta is stronger, harsher, and more bitter—but has more crema and higher caffeine. Most commercial espresso blends include both to balance cost, flavor, and crema.
