What’s a single-origin espresso? Very usually outlined, it’s an espresso produced from a single crop of espresso grown and processed in a single nation, area, cooperative or farm. In different phrases, it isn’t a mix of coffees grown somewhere else or at totally different instances.
Single-origin (S.O.) espressos enable an espresso drinker to discover the broader world of espresso in the identical conscious, knowledgeable means as espresso drinkers who style their coffees brewed as drip or French press. With single-origin espressos, the curious espresso drinker can discover the sensory impacts of variables like tree selection, processing methodology, rising elevation and, to some extent, roasting technique — explorations which can be tough to unattainable to pursue with blends. Plus, single-origins have the capability to shock us, and make the straightforward act of tasting an espresso shot or cappuccino a memorable mini-revelation that tasting a routine mix, even an excellent routine mix, can’t provide us.
Such espresso explorations would appear to be notably supported by this month’s tasting, as the entire 13 top-rated coffees we report on are recognized fairly particularly: by particular farm or co-op, by number of tree that produced them, and infrequently by rising elevation. And we had been in a position to inform one thing in regards to the roasting by taking Agtron coloration readings of the beans.
Tasting Colleagues
I used to be joined on this blind tasting of single-origin espressos by John DiRuocco, vice chairman of espresso at Mr. Espresso, a long-established (based in 1978) espresso roaster in Oakland, California. The Mr. Espresso motto, fairly justified by its observe, is “Italian inspiration, modern style.”

We carried out the tasting over a number of days on the lab within the Mr. Espresso roastery, with Brandon Talley, assistant director of espresso high quality at Mr. Espresso, pulling the pictures on a Faema E71E, and Espresso Assessment’s Jason Sarley in a supervising assist function. As traditional, we generated the pictures utilizing 18 grams of floor espresso to provide 36 grams of completed espresso, a comparatively customary ratio in North American observe. For the “with milk” evaluation, the shot was mixed with three components complete milk, heated however not frothed on the steam wand. As all the time at Espresso Assessment, the tasting was carried out blind, with Jason delivering the coffees recognized solely by numbers to John and me.
Significance of Processing Technique
When the tasting was completed and the outcomes had been tabulated, it turned out that one variable particularly moved to the entrance of the sensory line: processing methodology. (Processing methodology, readers will recall, describes the sequence of procedures that flip the moist seeds of contemporary espresso fruit into dry, secure, roaster-ready inexperienced espresso beans.) The dramatic impression of processing strategies involving anaerobic (restricted oxygen) fermentation and its rising variety of variations and purposes tended to upstage the impression of different variables that create variations amongst inexperienced coffees, like tree selection, rising elevation and varied extra typical processing strategies.

13 of the coffees we examined achieved rankings of 94 or 95, all of which we overview right here. Amongst these top-rated 13 samples, 9, or nearly 70 p.c, had been processed utilizing strategies that prominently integrated anaerobic fermentation. Among the many remaining 4 top-rated samples, two had been processed by the traditional moist or washed methodology (all comfortable fruit residue was faraway from the beans earlier than they had been dried), one by the honey or pulped pure methodology (skins had been eliminated, however the fruit flesh or mucilage remained on the beans throughout drying), and one by the pure methodology (the beans had been dried inside your entire fruit).

The impression of the anaerobic ferment could possibly be felt within the typically putting sweetness and stunning fragrant complexity amongst the entire 9 anaerobic-process samples. Nevertheless, the one pattern that displayed specific anaerobic character in its candyish sweetness and perfume-like flowers was the Royal Flamingo Colombia Crimson Fruits Campo Hermosa Edwin Noreña (94). John very a lot admired this espresso at 95 and felt it was coherent and full in its originality, with its intense aromatics supported by a sound construction. For me, nonetheless, there was a bit an excessive amount of strawberry gummy and never fairly sufficient espresso, although I managed a 92. However I believe many readers will go along with John’s tackle this one. Give this putting espresso a strive.
John and I switched sides with the quietly melodic, elegant Speckled Ax Ethiopia Dame Dabaye (John 92, Ken 95, web 94), which I discovered pure, poised and flawless. John discovered it a lovely however simple washed Ethiopia espresso. However, once more, strive it; you will not be blown away, however I strongly doubt you’ll throw any of it away both.
Tree Selection
The celebrated Geisha/Gesha number of Arabica, with its elongated beans, nice construction, and intensely floral, cocoa and stone-fruit character, has been one of many fundamental autos that bold espresso growers have relied on over the previous couple of a long time of their typically profitable makes an attempt to distinguish their inexperienced coffees and appeal to recognition and better costs for them. Genuine Geishas, notably these grown from seed of the unique Panama pressure (Geisha T2722), proceed to impress with their grand however balanced construction and intense floral, fruit and cocoa aromatics.

However Geishas might now not appear as new and totally different as they as soon as did. So making use of anaerobic processing to a espresso from a decent however in any other case unremarkable tree selection is an alternate approach to shock the customer with fragrant fireworks and seductive sweetness. And at decrease costs than may be anticipated for espresso from Geisha bushes, with their typically stingy yields and fussy wants. In fact, producers can double down and apply anaerobic processing to their Geishas, as is the case with the Massive Shoulders Espresso’s anaerobic pure Marcela Gesha Espressso (95), Euphora Espresso’s anaerobic washed Colombia Buenavista Ataraxia Geisha (94), and AOI Espresso’s Ethiopia Growers Reserve Gesha Village Gaylee Particular Fermentation (94), all of which pursue a particular cup by way of each distinctive tree selection and anaerobic processing.
Origin and Single-Origin Espressos
Seven of this month’s 13 highest-rated samples had been produced in Colombia, all in southern or south-central Colombia. Of the remaining six, three had been produced in Ethiopia, one in Rwanda, one in El Salvador, and one in Hawaii.
Why the preponderance of Colombias, clearly a well-liked origin, however till lately not the go-to origin for coffees meant for espresso? (Historically, that might be Brazil.) Primarily as a result of a cluster of farms in southern Colombia seem to have mastered the usage of advanced strategies of anaerobic fermentation, which, carried out skillfully, can remodel a high-grown, probably acidy espresso right into a lower-toned, richly advanced, espresso-friendly espresso.

True, among the different profitable coffees on this month’s tasting used easier, extra direct purposes of anaerobic strategies than the Colombia farms. However, all in all, solely two out of this month’s top-rated 13 samples had been processed utilizing legacy strategies historically related to the origins that produced them: The Wonderstate Colombia Sierra Morena Pink Bourbon (95) is a conventional washed-process Colombia, and the Speckled Ax Ethiopia Dame Dabaye (94) a conventional washed Ethiopia. Native tree selection might contribute to the success of MK Espresso’s Juru Rwanda Rulindo Crimson Bourbon Honey (94), although the honey processing methodology is atypical for a Rwanda.
Keep tuned, however it seems that the expectation that we are able to make constant associations between espresso origin and low cup character continues to erode as bold farmers all around the world tinker with tree selection (e.g., Geisha) and processing methodology.
Roast Shade and Espresso
Historically, Italian observe is to roast for espresso to round what People may name a darkish medium roast. Nevertheless, when a style for espresso drinks and European-style cafés first developed within the U.S. within the Eighties, roasters went actually darkish for espresso brewing. They aggressively dark-roasted high-grown Central America or Colombia coffees, producing intense, bitter coffees that required the softening, buffering impression of scorching frothed milk to render them drinkable. Later, many American specialty roasters migrated towards one thing extra like the unique Italian custom: reasonably dark- to medium-dark.
Right now, after all, on the vanguard of the U.S. specialty espresso scene, style in roast fashion has utterly flipped, no matter brewing methodology. Reasonably than every thing darkish, as was the case 20 years in the past, right now just about every thing is mild. Generally very mild, no matter meant brewing methodology.
Of the seven U.S. coffees reviewed this month, six are light-roasted. Just one, the Speckled Ax Ethiopia, was roasted modestly darker, to a little bit previous second crack, classifying it as a reasonably darkish roast. The six coffees from Taiwan roasters had been a bit darker roasted than the U.S. samples, tending towards medium or medium-dark, although none could possibly be referred to as outright darkish roasted.
Omni Roasts and Acidity
Most of this month’s coffees most likely qualify as what some within the espresso world name omni roasts—roasts that the roaster feels will do effectively when subjected to nearly any brewing methodology.
This observe—one roast for all brewing strategies—has a sensible benefit for espresso sellers, after all. Fewer merchandise, a extra compact stock, and maybe easier communication. The elevated technical sophistication obtainable right now in managing roast, facilitated by pc management and monitoring, might assist roasters apply roasting practices that are likely to spherical sharpness and soften and combine acidity in lighter roasts, making them extra espresso-friendly.
The possibly shiny, aggressive acidity attribute of high-grown, light-roasted coffees has all the time introduced an issue for espresso brewing. Some years in the past, when the observe of pulling espresso from such shiny, lighter-roasted coffees took off, I recall tasting some quite imbalanced espressos. Though we nonetheless run into an occasional quite sharply acidy single-origin espresso at Espresso Assessment, our tasting for this month means that roasters have gotten more and more skillful at sourcing and light-roasting single-origins for all-purpose brewing, and, by implication, for espresso.
Acid-Decreasing Anaerobics
The very fact that there have been so many anaerobic-fermented coffees among the many espressos we tasted this month might have helped the acidity-reducing trigger. Anaerobic processing tends to cut back or soften acidity, typically changing it with a backgrounded lactic tang, whereas encouraging a sweetness that helps stability any bitter edge to the acidity.
Single-Origin Espressos within the Café
After we selected this month’s subject, we had been a little bit afraid that single-origin espressos had had their day and had been on their means out of trend.
Maybe. Nevertheless, we acquired a reassuringly massive variety of submissions for this subject.
Roasters who despatched us top-rated coffees and with whom we subsequently corresponded had been largely divided in regards to the worth of single-origin espressos of their cafés. Typically, Taiwan roasters had been extra constructive than had been North American roasters, and for good motive, given brewing espresso at residence seems extra in style in Taiwan than within the U.S. Mark Shi of Taiwan’s MK Espresso reviews: “Since Taiwanese cafes banned on-site ingesting throughout the Covid-19 pandemic and most prospects had been working from residence, I discovered that many individuals who drank espresso day by day purchased automated espresso machines at the moment, so for the beans appropriate for espresso (together with blended beans and single-origin beans), the demand is trending greater and better.”
Arthur Chen of Taiwan’s Balmy Day Espresso Workplace (Ethiopia Anaerobic Washed G1 Wild Rose S.O. Sidamo, 94), gives an prolonged suggestion for a way roasting for espresso needs to be carried out (slowly), concluding that single-origin espressos “… needs to be like a style bomb, permitting the flavour of the espresso to be concentrated and targeted, in order that the single-origin espresso taste can bloom within the mouth like fireworks.”
American Single-Origin Skeptics
A usually extra skeptical angle amongst American roasters relating to single-origin espressos is voiced by Previous Soul Espresso’s Jason Griest (El Salvador Finca Loma La Gloria Pure Course of “Unicorn Lot”, 94). Jason writes, “Single origin espressos could be enjoyable, however we discover a ‘good’ one elusive to seek out and so, hardly ever have one on the bar at our outlets.” Jason echoes the place of many North American roasters, who really feel that an espresso espresso must be versatile above all: “Our fundamental espresso mix referred to as The Treatment is made up of three parts, designed to enrich one another when it comes to physique, acidity and candy/bitter notes that may be loved each as a straight shot and with milk.” Lee Paterson of Hawaii’s Hula Daddy (Kona Espresso Particular Choice, 94) factors out that “Since most of our gross sales are to North America, the place drip espresso is king, espressos are a small a part of our enterprise.”

Tim Coonan of Massive Shoulders Espresso (Marcela Gesha Espresso, 95) takes a extra encouraging middle-ground place: “Our S.O. espresso program serves three functions. These are coffees which can be difficult for roasters and baristas alike. So it’s academic for us. We discover these are appreciated by these common prospects who’re in search of a chance to each be taught extra about espresso and in addition [are] keen to discover some boundaries within the course of. These are prospects who additionally take pleasure in their espresso solo, not with milk.”
American Single-Origin Fans
Taking a wholehearted pro-single-origin place are Bryan and Beth Brzozowski of Royal Flamingo Espresso (Colombia Crimson Fruits Campo Hermosa Edwin Noreña, 94), who’re planning to increase their profitable e-commerce and wholesale enterprise to a brick-and-mortar café this yr. They write, “Single-origin espresso is one thing we’ve turn into recognized for in our espresso group and has performed a significant function in our e-commerce and wholesale development. After we open our café subsequent month, we’ll be leaning exhausting on single-origin espresso. … For instance, we’re planning to have a couple of choices on the menu the place prospects can order a drip and a shot of single-origin espresso comes alongside (a pair we’re calling the Barista’s Boilermaker).”

Summing up the pro-single-origin facet is Caleb Nicholes of Wonderstate Espresso: “We imagine that single-origin espressos have a definite and essential function in specialty espresso. In all of our café areas, we provide each a single-origin espresso, which is roasted lighter, in addition to a deeper roasted mix. Having a lighter-roasted espresso choice offers us the chance to introduce our prospects to a really light-roasted espresso expertise that may be very a lot reflective of a espresso’s selection, micro-climate and processing fashion. Whereas brighter, extra fruit-driven and fragrant espressos could be jarring for some espresso shoppers, it is a wonderful approach to develop perceptions round what espresso could be. We like to shock our prospects with one thing they’ve by no means tasted earlier than, and single-origin espresso is without doubt one of the greatest methods we have now discovered to try this.”
Single-Origin Espressos at House
In fact, café homeowners must please practically everybody who comes within the door. Shoppers solely must please themselves—or at most their households and company. So maybe the single-origin espresso sport, with its potential for espresso exploration and sensory revelation (together with its threat for non permanent disappointment) is greatest performed by shoppers at residence. In that case, we really feel that the coffees we overview this month provide a superb and numerous place to begin.
John DiRuocco Displays on the Tasting
John writes: “Roasters from all around the world submitted their most interesting choices from acquainted to unique. It was an thrilling problem to explain and consider these coffees. The huge assortment of processes and varieties translated to a thrill trip of aroma, acidity, and fruit. As a roaster based mostly in Italian espresso custom, our method to espresso at Mr. Espresso is predicated on the concept of stability and roundness, one thing that may be loved a number of instances a day, day by day. What set one of the best of the coffees we tasted aside for me weren’t solely taste profiles that contained explosive fruits, intricate floral flavors, and intense acidity, however people who had been balanced by a pronounced sweetness and spherical physique to create a memorable espresso expertise.”
