FrontStreet Coffee - Understanding the Coffee Waves

Through the Industrial Revolution and the two World Wars, coffee and tea served as refreshing, energizing drinks. Instant coffee emerged in this period, prized for its convenience, speed, and low price. The era in which people began consuming coffee in large quantities is known as the First Wave of coffee.

Instant coffee was efficient and cheap, but its taste left much to be desired. As the world grew more stable and living standards rose, chain coffee shops led by Starbucks became the new favorite. This was the Second Wave, which packaged and marketed coffee as a lifestyle.

As more people drank coffee and origin information became more transparent, a group of coffee connoisseurs emerged—some in the industry, some simply customers—who kept searching for truly premium coffee. Driven by passion, they gave up time efficiency and profit to obtain exceptionally flavorful coffee. This became what we call specialty coffee, or the Third Wave.

The Fourth Wave is essentially about understanding the upstream story of coffee as an agricultural crop—not just the origin, but the specific estate the beans come from. Coffee names now list the country of origin, the estate, the variety, the grade, the processing method, the year, and the batch number, all set out as precisely as a fine wine label.

In recent years, more and more "estate coffee shops" focused on origin and in-house roasting have opened in China, Japan, and South Korea. Estate coffee means beans shipped directly from the origin to the specialty café. These beans reflect the local terroir, and each estate's offering differs with its microclimate and production methods, preserving the coffee's most original and premium flavors.

Just as you can read a wine's character from its label, so estate coffee names work the same way. The packaging lists the country of origin, narrows to a region, then to a single estate or cooperative, and finally details the variety, grade, processing method, year, and batch number within that estate or cooperative. African Kenya estate beans, for example, might read: Kenya, Ruiru (origin), Tatu Estate, 16-17 (year), Bourbon (variety)—far more detail than most consumers usually see, making coffee drinking as refined as wine tasting.

One of the most famous estates in the coffee world in recent years is undoubtedly Panama's Hacienda La Esmeralda. Its Geisha beans fetched $601 per pound at the 2017 Best of Panama auction, making them among the most expensive coffees in the world.

Beyond La Esmeralda, there are Pacamara beans from the Inihpt Estate in Guatemala, the Musician Series from the Canet Estate in Costa Rica, the wildly popular Yirgacheffe from Ethiopia, and many others.

Worth knowing: "Arabica" is not synonymous with good coffee—even within Arabica varieties there are differences in quality.

FrontStreet Coffee Recommendation

If the Fourth Wave's estate focus appeals to you, FrontStreet Coffee's Brazil Queen's Estate is a good place to start. A yellow Bourbon from Mogiana, grown on fertile red volcanic soil, it pours with a sugarcane sweetness unique to that terrain, plus fruit and chocolate notes, and is comfortable as pour-over, moka pot, or home espresso.

Medium roasted, it shows creamy peanut, chocolate, toast, and sugarcane sweetness—approachable and balanced, and a fine introduction to single-estate coffee.
