How did the coffee industry evolve in the 20th century?

At the dawn of the 20th century, coffee was largely an undifferentiated raw good. Consumers typically purchased green beans in bulk and roasted them at home. The century saw a radical shift as industrialization allowed companies like Hills Brothers, Folgers, and Maxwell House to dominate the market by selling pre-roasted, packaged coffee. The invention of vacuum-sealed tins was a pivotal moment, allowing roasters to preserve freshness and distribute coffee on a national scale for the first time.

Simultaneously, the quest for convenience led to the birth of instant coffee. While early experiments date back to the 18th century, it was Satori Kato’s 1901 patent that provided a viable method for a stable, soluble product. This technology was refined over the decades, most notably by Nescafé in the 1930s. The product’s true explosion in popularity occurred during World War II, when it became a standard ration for soldiers, cementing its place in the global diet.

This era also saw the rise of the 'first wave' of coffee, characterized by a focus on mass production, affordability, and convenience over origin or flavor profile. To meet the massive demand for instant products, the industry increasingly relied on Robusta beans, which were cheaper and easier to mass-produce than the more delicate Arabica varieties. This shift contributed to the perception of coffee as a bitter, one-dimensional commodity.

By the latter half of the century, the industry began to pivot again. The emergence of specialty coffee—often cited as the 'third wave'—began to challenge the dominance of mass-produced, instant coffee. This movement emphasized transparency, high-quality sourcing, and distinct flavor profiles, effectively reversing the century-long trend of prioritizing convenience over quality. Today, the industry continues to balance these legacies, with modern technology now being used to elevate the quality of even soluble coffee products.

In practice, this history explains why we see such a stark divide in the market today. The 20th century built the infrastructure for the coffee we drink, but it also created the very standards that specialty coffee enthusiasts now work to transcend by focusing on the farm, the roast, and the brewing method.
