Throughout all ranges of the availability chain, specialty espresso has totally embraced automation. For an trade that was as soon as outlined by its emphasis on artisanry and craftsmanship, this underscores a major shift in favour of consistency and high quality management.
With current advances in expertise, automation has lowered, and in some circumstances eradicated, the probabilities of human error in duties like roasting and brewing. In flip, companies can supply constant, uniform espresso experiences – an more and more necessary issue for shoppers.
However whilst automation transforms the trade, optimising effectivity and standardising the scaling of operations, many roasters and café house owners nonetheless maintain onto the essence of specialty espresso: craft and artistry. Hanging the fitting steadiness between these and automation has turn out to be important for companies to thrive in an more and more aggressive market whereas nonetheless retaining their model identification and values.
I spoke to Stephen Brown, proprietor of artisan roaster and pottery maker Potterbeans in Cornwall, UK, to seek out out extra.

Automation has redefined roasting
Espresso roasting is an historic follow courting again to the fifteenth century in Africa and the Center East. During the last hundred or so years, expertise has remodeled the method, emphasising a a lot larger concentrate on consistency and high quality management.
Automation emerged over the previous few many years as a means for roasters to exactly measure and manipulate quite a lot of roasting parameters, together with temperature, time, and airflow. In flip, roasters can create repeatable, customised profiles that spotlight a espresso’s greatest traits on the contact of a button – massively enhancing effectivity and elevating espresso high quality.
“The power to gather and share knowledge from thermocouples positioned within the bean pile and different areas of the machine has accelerated studying for everybody concerned in espresso roasting,” Stephen says.
In specialty espresso specifically, trade professionals are leveraging automation to push the boundaries of roasting even additional, creating modern new methods that unlock the complete spectrum of a espresso’s flavours and aromas.
“Our willingness to share that data throughout on-line platforms has allowed individuals from outdoors the trade to enter the combo, usually bringing distinctive approaches that don’t comply with widespread practices and conventional approaches,” Stephen provides.
But it surely’s nonetheless an artwork kind
Third wave and specialty espresso have been born from a need to “do issues in another way” within the trade, outlined by their emphasis on craft and artistry. Phrases like “hand roasted” and “hand brewed” have been widespread, highlighting the technical ability of roasters and baristas to carry out the perfect attributes of espresso.
Whereas current cutting-edge expertise has improved consistency in roasting, it stays an artwork which should be mastered with follow and expertise. Excessive-quality roasting nonetheless requires in-depth information about a lot of variables, together with origin, selection, processing methodology, and bean density, underscoring the effort and time wanted to develop the mandatory expertise.
As producers combine extra automated and AI-driven options of their machines, roast profile growth is about to evolve even additional, arguably making it simpler to create and duplicate roasting curves. Some argue that this dangers eroding the ability and instinct that nice roasters must have, however in the end, human-driven actions will at all times be important to the roasting course of.
“As I perceive it, regardless of all of the technological advances, there are particular situations that come up the place software program won’t be capable of navigate an unexpected blip within the roasting course of in the identical means that an skilled roaster might,” Stephen says.
“We’re not at a degree simply but the place it’s doable to surrender the reins completely.”
Sustaining a connection to roasting
Specialty espresso is a differentiated product, underscored by the eye to element that actors contribute to the availability chain. Producers take nice care rising, harvesting, and processing their espresso, whereas exporters guarantee shipments are saved and transported accurately to take care of high quality.
Baristas, in the meantime, put together drinks with precision and consistency, whereas roasters spend time understanding completely different variables that have an effect on the flavour growth of their coffees to realize the perfect outcomes. Throughout the board, human intervention performs an necessary position within the closing product.
“Crucial connections {that a} roaster has with espresso are earlier than it goes into the machine drum and the way it tastes as soon as it leaves the roaster,” Stephen says. “By these connections, you may higher perceive the components that impression flavour, comparable to origin, processing methodology, and altitude.”
A rising reliance on expertise, nonetheless, can improve the chance of dropping the human contact that provides worth to the trade. Overusing automated and AI-driven options can dilute the craft parts of roasting in specialty espresso, diminishing its level of differentiation.
To keep up a reference to the roasting course of and spotlight its artisanal facets, Potterbeans makes use of regionally sourced oak wooden to roast its espresso. This age-old methodology largely fell out of trend within the late 19th and early 20th centuries as fuel and electric-powered machines turned more and more in style.
“It was very a lot by likelihood that we acquired a dual-fuelled roaster,” Stephen tells me. “We meant to set it up as a fuel powered machine, however I first needed to attempt wooden roasting.
“After tasting the outcomes, I made a decision that this was how we have been going to roast espresso. It was a really memorable second.”
The impression of wooden roasting on espresso flavour
Fuel turned the go-to warmth supply for a lot of roasters within the early 1900s, permitting them to simply management roasting temperatures, whereas electrical machines some many years later helped espresso companies scale back their working prices and enhance consistency.
Nonetheless, there’s a area of interest group in specialty espresso that has saved the custom of wooden roasting alive. Roasting over wooden is a slower course of in comparison with utilizing fuel or electrical energy, largely as a result of wooden accommodates between 12 and 15% moisture, whereas fuel is a dry pure warmth supply.
“It was essential to us that the wooden wasn’t kiln-dried, which burns gas to create gas, and was regionally sourced,” Stephen says. “Sustainability was our prime motivator, however we now have since turn out to be conscious of how solar-dried wooden advantages espresso high quality.”
Larger ranges of moisture inevitably lengthen the primary stage of the roasting course of, often known as the drying section, requiring a extra expert and cautious method.
The result’s a full-bodied, easy flavour profile that retains extra of the espresso’s pure oils, serving to to steadiness acidity and sweetness – making it a super choice for espresso specifically.
Balancing artisanry with consistency
For roasters to seek out success in at the moment’s market and meet client expectations, consistency is every thing. However concurrently, specialty espresso corporations want to remain on model and retain a concentrate on craft, which implies balancing each has by no means been extra necessary.
Stephen explains that to realize this, Potterbeans implements a lot of high quality management processes to seize and analyse roasting knowledge.
“Measuring mass misplaced throughout roasting and amassing as a lot knowledge as doable ensures we are able to recreate our successes and perceive the way to get rid of any defects that may occur,” he says. “Along with this, we use and goal particular percentages of mass loss through the roast to assist gauge the roast degree and bean color.”
In an more and more automated trade, holding onto craftsmanship and human ability is crucial to maintain the values of specialty espresso intact. Very like the trending “wood-fired pizza”, wooden espresso roasting conveys a handcrafted high quality that pulls a sure nook of the market.
In keeping with analysis, 77% of shoppers are prepared to pay extra for merchandise they understand as handcrafted. The artisanal high quality of specialty espresso stands out as a degree of differentiation in an more and more commercialised market, permitting roasters to seek out their area of interest.
Craftmanship is synonymous with ability
Technological developments in roasting actually release roasters’ bandwidth for different duties, permitting them to concentrate on different areas of their enterprise, however human contact and ability will at all times be integral.
Because it’s the first gas supply, the standard of wooden impacts the roasting course of. Managing key variables like moisture, density, and dimension requires instinct and expertise to realize the optimum outcomes, making human-driven actions indispensable.
Stephen explains how he and his staff perform visible and tactile assessments to know how a lot power a bit of wooden might launch because it burns. A fast visible evaluation can be achieved between roasts to verify how a lot power is left within the current fireplace, together with checking the machine’s drum temperature to evaluate whether or not extra wooden must be added to finish the following roast.
Automation has remodeled and benefitted espresso roasting in infinite methods, however retaining an emphasis on craft and artisanry will at all times be part of specialty espresso.
Whereas it will possibly streamline operations and enhance effectivity, automated expertise can by no means totally substitute human intuition, ability, and information acquired by expertise – which is what makes specialty espresso so distinctive.
