Specialty espresso has remodeled espresso. The {industry}’s desire for fruit-forward, sweeter, and brighter coffees has led many roasters and cafés to maneuver away from conventional espresso roasts. Darkish, roasty, and robusta-heavy blends that had been so widespread within the late Nineteen Nineties and early 2000s have largely been changed with medium-to-light roasts and single origin choices.
Within the wake of those modifications, there was a flurry of innovation in espresso extraction that’s redefining the drink in new methods. Coarser grind sizes, shorter extraction occasions, and decrease stress have created turbo pictures – leading to sweeter and cleaner flavours.
As espresso costs have climbed increased in recent times, we’ve seen a revert to blends and high-quality robusta. Specialty espresso pioneers like Blue Bottle launched the First Espresso arabica-robusta mix in early 2024, which pays “homage to espresso of the Fifties”.
Though it’s reductive to say that espresso has come full circle, there are indicators that it’s returning to its roots. To search out out extra, I talked to Maurizio Giuli, CSO at Simonelli, Chiara Bergonzi, founding father of Lot Zero, and Patrik Rolf, CEO of April Espresso Roasters.

The origins of the drink
When speaking about how espresso has modified, we first want to know what it has advanced from. Iconic Italian model illycaffè outlined a single espresso as 7g of espresso extracted between 88°C and 93°C below 9 bar of stress to supply a concentrated beverage of not more than 30ml.
This places the “conventional” espresso shot at a 1:4 coffee-to-water ratio, considerably increased than the 1:2 or 1:3 ratios generally utilized in specialty espresso retailers at the moment.
Roast profile is much less mentioned, nonetheless. Whereas many assume that conventional espresso roasts would have been very darkish, a current video from James Hoffmann brewing espresso from the Fifties signifies that medium roasts might have been well-liked.
One other widespread assumption is that conventional espresso used robusta-heavy blends. Historic proof, nonetheless, doesn’t completely assist this concept.
Maurizio Giuli is the Chief Technique Officer at Italian espresso gear producer Simonelli Group. “Historically, the principle element of Italian espresso blends was Brazilian arabica,” he says. He explains that the transfer in direction of robusta didn’t occur till the mid-Nineteen Seventies when “excessive inflation in Italy coupled with a manufacturing disaster in Brazil meant that to maintain the value of espresso inexpensive, a share of Brazilian arabica was changed with robusta”.
Espresso tradition and consumption habits had been additionally considerably completely different just a few a long time in the past. Chiara Bergonzi, the founding father of specialty espresso roaster Lot Zero in Milan, Italy, explains how.
“A ‘conventional’ espresso is deeply rooted in Italian tradition, the place the main focus is on simplicity, fast consumption, and affordability,” she says. “It’s a drink consumed rapidly on the bar, conventionally for a really low cost value. Espresso is usually thought-about a fast pick-me-up, usually loved standing, and with out a lot fuss over the flavour profile. The main target is on depth, physique, and stability, quite than exploring nuances.”
Espresso continues to evolve
Technological evolution revolutionised espresso extraction and consumption. Previous to the late Nineteen Forties, machines may solely brew espresso below 2 bar of stress – which means baristas had been in all probability serving espresso extra akin to a moka pot.
The addition of piston levers after World Struggle Two profoundly modified the character of espresso brewing, and in the end gave us the drink we all know at the moment. Achille Gaggia found that boilers can drive water right into a cylinder earlier than it’s pushed water by means of a mattress of espresso – which is the place the time period “pulling a shot” comes from.
This led to a dramatic improve in brewing stress from 1.5 to 2 bar to eight to 10 bar, which additionally resulted in crema. Gaggia referred to it as “caffe creme” as a result of the ensuing espresso “was of such high quality that it produced its personal cream”.
Modifications continued all through the remainder of the twentieth century, particularly as robusta was added to blends. To masks and scale back the overly bitter flavours, darker roasts grew to become extra outstanding and baristas tightened coffee-to-water ratios.
However as specialty espresso emerged within the Nineteen Nineties and 2000s, approaches to roast profiling modified as soon as once more.
“The {industry} went in a really completely different path,” Chiara says. “Sourcing higher-quality espresso meant flavour profiles grew to become rather more advanced, highlighting acidity and sweetness that you simply wouldn’t sometimes discover in a standard espresso.”
To showcase high quality and delicate flavours, extra roasters began to embrace lighter roasts. Given its a lot shorter extraction occasions than filter espresso, nonetheless, espresso wanted to be extra soluble, so mild roasts weren’t usually your best option.
“As specialty espresso was turning into well-liked, espresso consumption was rising exterior of Italy,” Maurizio tells me. “There was a conflict between completely different approaches to roast profiling and what was thought-about greatest for specialty espresso and espresso.”
Roasting for espresso
In lots of instances, lighter roasts lead to overly acidic and unbalanced espresso. This drawback was compounded by a “lighter-is-always-better” mentality no matter how the espresso was brewed – particularly as single origins grew to become extra well-liked.
Contemplating that solubility is essential to extracting glorious espresso, extra developed roast profiles normally work higher.
“Medium roasts have gained reputation for a number of causes, notably as a consequence of a rising consciousness that darkish roasts are likely to overshadow the optimistic attributes of espresso and intensify bitter flavours,” Chiara says. “In distinction, medium roasts enable for the caramelisation of sugars, making a extra balanced profile that harmonises sweetness and acidity. This strategy minimises the bitter elements, leading to a sensory profile that showcases shiny, citrusy, and floral notes.”
Specialty espresso reinvents espresso
As specialty espresso consumption grew around the globe, baristas and roasters adopted a extra scientific strategy to roasting and brewing.
“We’re rather more exact, utilizing superior gear that permits for higher management of variables like stress, temperature, and grind measurement,” Chiara says. “This has created a extra refined espresso expertise, enhancing consistency and the flexibility to extract extra advanced flavours.”
Training can also be a tenet of specialty espresso, serving to to bridge data gaps within the provide chain and improve client consciousness.
“In the present day’s espresso drinkers are rather more knowledgeable about origins, processing strategies, and even the environmental affect of their espresso, resulting in a extra considerate and aware consumption expertise,” Chiara provides.
Competitions have additionally performed a pivotal function in redefining espresso. Patrik Rolf is the founding father of Denmark’s April Espresso Roasters. He underscores the significance of the World Barista Championship, which he says “has all the time been on the forefront of espresso brewing innovation, made doable by a greater understanding of apparatus and water high quality, amongst different elements.”
The industry-standard 1:2 ratio was turned on its head on the 2013 version when Australian Barista Champion Matt Perger pulled longer “espresso pictures” – just like allongé or lungo pictures widespread in Quebec, Canada and Italy.
Within the years since, there was a flurry of experimentation with longer ratio espresso brewing exterior of the competitors, from the hybrid espresso-pour overs at California’s Cat & Cloud to the Noma-canos developed on the Danish fine-dining restaurant Noma.
A scientific paper printed in 2020 aimed to construct on this innovation and systemically enhance espresso extraction. Researchers discovered {that a} decrease dose, coarser grind measurement, and shorter extraction time decreased channelling and elevated extraction time, which produced a extra balanced espresso with larger flavour readability.
Unconventional brewing strategies
There’s little question that experimenting with espresso extraction provides worth to the {industry}. The aim of the 2020 analysis paper was not solely to enhance extraction consistency but in addition to discover a cheaper approach to pull pictures. Smaller doses and shorter brew occasions imply cafés use much less espresso and may serve drinks extra rapidly, serving to them save an estimated US $3,600 a 12 months.
Nevertheless, making use of an strategy developed in a scientific setting to a business setting doesn’t all the time work. Furthermore, utilizing completely different variables would drastically change how we expertise espresso, which can not align with client preferences.
“Nearly all of customers, particularly in sure markets, are unlikely to embrace brighter and extra acidic flavour profiles in espresso,” Chiara says. “Whereas there’s a rising appreciation for the complexity of washed coffees, many espresso drinkers nonetheless gravitate in direction of milder, fuller-bodied flavours that darker roasts and unwashed coffees sometimes supply.”
Chiara provides, nonetheless, that clients have developed a deeper understanding of espresso, which has shifted consumption habits.
“Arabica tends to be extra balanced, permitting the pure sweetness and acidity to shine by means of,” she says. “This encourages drinkers to expertise extra nuanced flavours and add much less sugar to their espresso.”
A return to custom?
Since its invention within the late nineteenth century, espresso has undergone an enormous transformation, largely due to specialty espresso. However current reverts to blends and robusta point out a return to its roots.
As espresso costs and enterprise prices have steadily climbed over the previous couple of years, an increasing number of specialty espresso roasters have launched high-quality blends to their choices. An economical menu choice, blends additionally are likely to lead to extra balanced and well-rounded flavour profiles for espresso than single origin heaps.
Concurrently, we’ve additionally seen robusta rise to prominence. A helpful addition to blends and a steadily rising single origin providing, robusta has proved to be an inexpensive choice for roasters to handle their margins.
In early March 2024, pioneering specialty espresso roaster Blue Bottle launched the First Espresso arabica and robusta mix to “reimagine the profile of the primary trendy espressos”. Impressed by the Fifties, which the model describes as pivotal to the popularisation of espresso, the product signifies a shift in direction of a standard strategy to blends, roast profiles, and occasional flavour.
The ever-changing nature of espresso
The reply to the query of whether or not espresso ought to change is that it has always been evolving since its inception.
“Change has been essential to maneuver us away from the errors of the previous and in direction of a greater understanding of find out how to brew and serve a superb espresso,” Patrik says. “Specialty espresso is, in some ways, an expression of our personal perspective on espresso, so there’s no proper or fallacious means.”
Extra modifications are inevitable, too. “What is taken into account ‘good’ now received’t be ‘ok’ in ten years,” Maurizio says. “Shopper preferences will, in fact, additional evolve within the years to come back.”
Some of the profound modifications has been client notion of espresso. Extra individuals now benefit from the drink for its flavour and sensory expertise quite than only a fast power repair.
The query of whether or not espresso can ever be too “unconventional”, nonetheless, will all the time stay.
“I wouldn’t say espresso has develop into too unorthodox, however that we remained stagnant for too a few years, not like different meals traits which have advanced and influenced the tradition round them,” Chiara says. “Specialty espresso is elevating client consciousness, permitting them to higher perceive and recognize what’s of their cup. This evolution isn’t about transferring away from custom however elevating requirements and growing appreciation for the craft.”
From the extreme and daring flavours related to its early days to the brighter and extra acidic sensory profiles we all know at the moment, espresso has come a great distance.
Traits within the espresso {industry} are cyclical, so client preferences are more likely to shift over time. Whichever means they swing, there’ll all the time be room for additional innovation.
