The concept of “coffee waves” — first, second, and third — was introduced by the specialty coffee writer Trish Rothgeb in 2002 as a way of describing distinct eras in how coffee has been produced, marketed, and understood. The terminology has stuck, partly because it captures something real about the different relationships consumers have had with coffee across the 20th and early 21st centuries.

The first wave is the story of how coffee became a mass-market product — widely affordable, universally available, standardised in quality, and valued primarily as a functional caffeine delivery system rather than as a complex agricultural product. It is the story of Nescafé, Maxwell House, and the institutional structures that turned a fascinating and varied crop into a commodity indistinguishable from any other.

The Invention of Instant Coffee

The key technology enabling the first wave was instant coffee. The concept of dissolving coffee into a dry powder that could be reconstituted with hot water had been explored since the 19th century — various inventors in Japan, the United States, and Britain claimed priority on early versions — but the product that made instant coffee a mass-market phenomenon was Nescafé, launched by Nestlé in Switzerland in 1938.

Nescafé used a spray-drying process that produced a shelf-stable powder capable of dissolving instantly in hot water, yielding a consistently uniform cup. The coffee used to make it was primarily commodity robusta — cheap, high-yielding, and caffeine-rich — selected for solubility and yield rather than for flavour complexity. The resulting drink was unmistakably coffee in aroma and effect, but stripped of the nuance and variation that characterised well-made filter or espresso coffee.

From a supply-chain perspective, this was extremely efficient. Nescafé could be manufactured in large facilities, shipped globally, stored for months, and prepared by anyone with access to hot water. The skill, equipment, and attention required to make good conventional coffee were eliminated entirely.

World War II and Global Diffusion

The Second World War was the event that turned instant coffee from a commercial product into a global standard. The United States Army commissioned instant coffee in enormous quantities — it was included in soldiers’ rations from 1942 onward as a cheap, lightweight, storable source of caffeine. American forces served in every theatre of the war, and they brought their instant coffee with them. Recipients of American aid packages across Europe, Asia, and the Pacific encountered Nescafé and similar products during or immediately after the war.

In countries like Japan, which had no indigenous coffee tradition, the American military presence created the first widespread exposure to coffee — typically instant coffee — and planted the seed of a coffee culture that would develop dramatically in subsequent decades. In Europe, where food supplies were disrupted by years of war, instant coffee arrived as part of reconstruction aid and became the first regular coffee experience for a generation that had grown up during rationing.

Maxwell House, the American brand that had been using the slogan “Good to the Last Drop” since 1917, similarly expanded globally on the back of wartime distribution and post-war economic growth. By the 1950s, instant coffee dominated coffee consumption in the United States, Britain, and many other markets.

The Commodity Machine

Behind the consumer-facing story of Nescafé and Maxwell House was a commodity market of extraordinary scale and complexity. The growth of mass-market coffee consumption drove demand for cheap coffee supply, which intensified the focus on yield and volume at the expense of quality. Robusta cultivation — in Brazil, Vietnam, and across West Africa — expanded dramatically. Arabica was increasingly selected and processed for consistency and cost-efficiency rather than for cup quality.

The global commodity coffee price — traded on the New York exchange — became the reference point around which the entire supply chain organised itself. When prices were high, producers expanded. When prices collapsed — as they did in 1989 when the International Coffee Agreement broke down, removing the quota system that had maintained price floors — producers were devastated. The collapse of the ICA in 1989 pushed coffee prices to their lowest real level in a century, contributing to rural poverty across Latin America, Africa, and Asia on a significant scale.

This price structure ensured that the people who actually grew the coffee — smallholder farmers in Ethiopia, Guatemala, Vietnam, and a hundred other countries — received a tiny fraction of what consumers paid in supermarkets. The intermediaries who bought, processed, shipped, and packaged the coffee captured most of the value. The farmer’s share of the retail coffee price was, in many cases, less than ten cents per cup.

The Standardisation of Taste

The first wave was also a story of taste standardisation. The commercial roasting industry, which expanded rapidly to meet the demand for pre-ground vacuum-packed coffee and instant powder, converged on a set of flavour profiles designed for maximum consumer acceptability — low acidity, full body, straightforward bitterness. Coffee was roasted dark enough to mask variation in the underlying bean and to produce a consistent sensory experience regardless of origin.

The result was that coffee became essentially uniform across brands and origins. A can of Maxwell House and a tin of Nescafé and a bag of Folgers all delivered roughly the same experience — caffeinated, bitter, consistent, and entirely disconnected from the diversity of the agricultural product from which they were made.

For the specialty movement that followed, this uniformity would be both the problem to be solved and the baseline against which everything new would be measured.
