The History of Instant Coffee: From Satori Kato in 1903 to Nescafé and the Modern Market

Instant coffee occupies an unusual position in the world of coffee. Within the specialty coffee community it is often dismissed or ignored entirely, treated as a category so far removed from serious coffee that it barely warrants comment. Among the global population of coffee drinkers, it is the dominant form. According to data from the International Coffee Organization, instant coffee accounts for approximately 34 percent of all coffee consumed worldwide, and in some markets, including the United Kingdom, Australia, Japan, and much of Eastern Europe and South America, it commands majority or near-majority market share. The technology that makes it possible, the conversion of brewed liquid coffee into a dry soluble powder that reconstitutes instantly in hot water, is not trivially simple, and the story of how it was developed, commercialised, and propagated through two world wars and global trade is richer than most people who stir a spoonful into a mug will ever know.

The Earliest Experiments: Before Satori Kato

The idea of a soluble, portable coffee product preceded practical realisation by several decades. A British patent was filed in 1771 for a "coffee compound" that could be prepared without brewing, though the product was not widely developed commercially. In 1853, the United States military used a compressed cake of coffee and sugar during the Civil War, a precursor to the concept of portable coffee rations, but this was not a soluble powder in the modern sense.

David Strang of Invercargill, New Zealand, received a patent in 1890 for a process to produce soluble coffee, which he sold under the brand name "Strang's Coffee." The New Zealand patent preceded more famous claims, but Strang's product did not achieve wide commercial success or historical prominence. A Japanese-American chemist named Satori Kato, working in Chicago, is generally credited with the first US patent for a practical soluble coffee process, filed in 1901 and granted in 1903. Kato presented his instant coffee at the Pan-American Exposition in Buffalo in 1901. His formulation produced a powder that dissolved readily in hot water, though the flavour quality was limited by the processing methods available at the time.

A Belgian-American inventor named George Constant Louis Washington developed a more practical and commercial version of instant coffee independently, around 1909. Washington, who lived in Guatemala and observed crystals of dried coffee forming on the spout of his silver coffee carafe, developed a process to produce these crystals consistently. His company, G. Washington Coffee Company, launched in 1910, became the first commercially successful instant coffee brand in the United States and was the product used in World War I American military rations. Soldiers wrote home describing "a cup of G. Washington" as a reliable comfort in the field.

The Science of How Instant Coffee Is Made

Modern instant coffee is produced by one of two methods: spray drying or freeze drying. Both begin with brewing large volumes of coffee concentrate from ground roasted beans using hot water extraction under pressure, producing a liquid several times more concentrated than normal brewed coffee.

In spray drying, the liquid coffee concentrate is pumped into a large heated chamber and sprayed through a nozzle as a fine mist. The water evaporates almost instantly in the hot air, leaving behind tiny dry particles that fall to the chamber floor and are collected as powder. Spray drying is rapid and economical but subjects the coffee to high heat during drying, which degrades many of the volatile aromatic compounds responsible for fresh coffee flavour. The resulting powder is shelf-stable, free-flowing, and dissolves instantly, but its flavour profile is noticeably flatter than brewed coffee.

Freeze drying, developed for commercial coffee production in the 1960s, produces a higher-quality product. The liquid concentrate is frozen at extremely low temperatures, typically around minus 40 degrees Celsius, forming a solid. This frozen material is then placed in a vacuum chamber where the ice sublimes, converting directly from solid to vapour without passing through a liquid phase. The result is a granular or crystal product with a more porous structure that retains more of the coffee's aromatic complexity than spray-dried powder. Freeze-dried instant coffees are sold at a price premium and marketed as superior quality products. Brands including Nescafé Gold, Douwe Egberts, and Starbucks Via (which uses a proprietary microground process rather than pure freeze-drying) occupy this higher-quality tier.

Nescafé: The Brand That Made Instant Coffee Global

Nescafé's origin is a case study in large-scale industrial problem-solving. In 1930, Brazil, then producing approximately 60 percent of the world's coffee, faced a catastrophic oversupply crisis following years of overproduction. The country approached Nestlé, already one of the world's largest food companies, to develop a product that could absorb the surplus by converting green coffee into a stable, shelf-long product that could be stored, traded, and consumed without the infrastructure of fresh-coffee brewing.

Nestlé's chemist Max Morgenthaler led the development team, working from 1930 to 1937 on the formulation. The challenge was producing a soluble coffee product that maintained acceptable flavour quality through the drying process, something none of the previous formulations had fully achieved. Morgenthaler's team developed a spray-drying process in which coffee was mixed with a carbohydrate (initially lactose, later modified) to stabilise the aroma compounds and improve the flavour of the final product. Nescafé launched in Switzerland on April 1, 1938. Within a year it was being sold in France, Great Britain, and the United States.

World War II accelerated Nescafé's global penetration in a way that no marketing campaign could have replicated. The United States military incorporated Nescafé into standard field rations beginning in 1942, and the entire US production of Nescafé through 1944 was allocated to military supply. Millions of American, British, and Allied soldiers consumed Nescafé daily as the only reliable coffee available in field conditions. By the war's end, Nescafé was associated in the minds of veterans and their families with reliability, comfort, and accessibility in difficult circumstances. The brand emerged from the war with an established position that translated directly into civilian market dominance.

The Postwar Market and the "Coffee Wars"

Through the 1950s and 1960s, Nescafé competed primarily with other instant brands in a market where brewed coffee remained the majority preference in the United States and Europe. Maxwell House, Folgers, and other major American brands developed their own instant products. In 1964, General Foods launched Maxim, the first freeze-dried instant coffee marketed to consumers in the United States, at a significant price premium over standard spray-dried products, successfully creating a quality tier within the instant category.

By the 1970s, Nescafé had achieved market leadership in Britain, Germany, Australia, Japan, and much of South America. In Japan, where canned coffee vending machines were proliferating (the first canned coffee, Pokka Coffee, launched in 1969), the category evolved in a distinct direction that would eventually influence the ready-to-drink coffee market globally. Japan's Ueshima Coffee Company (UCC) launched canned café au lait in 1969, and by the 1980s Japan had the world's most developed cold-coffee-in-a-can retail market, a category later studied and imitated by brands worldwide.

The UK market became particularly interesting from a cultural standpoint. Britain, which had never developed a strong filter-coffee or espresso tradition in its domestic food culture, adopted instant coffee as the national default with a thoroughness that surprised even Nestlé's projections. By the 1980s, over 80 percent of all coffee consumed in British homes was instant. This figure has declined with the growth of coffee capsule systems (Nespresso launched in 1986, Dolce Gusto in 2004) and espresso machine adoption, but as of 2023 instant coffee still accounts for approximately 75 percent of British retail coffee volume by unit, a figure with no close parallel among major European coffee-consuming nations.

Third-Wave Instant Coffee: The Category Reinvented

The specialty coffee movement largely ignored instant coffee through the 1990s and 2000s. This changed with the development of new processing technologies that made high-quality instant coffee from single-origin beans with light roasts feasible. Starbucks Via, launched in 2009, used a combination of microground roasted coffee and soluble coffee to produce an instant that retained more aromatic complexity than standard spray-dried products. It was sold at approximately $1 per sachet, several times the unit cost of Nescafé, and targeted the existing Starbucks customer who wanted their coffee experience to be portable.

Specialist instant coffee brands followed, including Swift Cup (founded 2015 in the United States), Voila Coffee, and Verve Coffee Roasters' instant range. These products use freeze-drying of specialty-grade arabica coffee brewed to barista standards before processing, aiming to produce a soluble product with a cup quality competitive with pour-over coffee. Independent taste tests by publications including Sprudge and The New York Times Wirecutter have found that the best current specialty instant coffees are genuinely difficult to distinguish from brewed filter coffee in blind testing conditions, a claim that would have been implausible a decade earlier.

Instant coffee's association with low quality is, for these newer products, outdated. The underlying technology has improved, the sourcing of the raw coffee has improved, and the market segment willing to pay a premium for a convenient but quality product has grown. Whether this represents a permanent repositioning of the category or a specialty niche within an otherwise price-sensitive market remains to be seen. Globally, the dominant instant coffee products remain large-volume, price-competitive brands, with Nescafé commanding approximately 45 percent of the global instant coffee market as of 2023.
