The Espresso Overview lab has smelled like a sweet retailer for the previous couple of weeks — a Willy Wonka manufacturing unit for grownups. Of the lots of of coffees we cup yearly, a rising share of them are natural-processed. Within the wine world, the phrase “pure” doesn’t imply something particularly, is extra of a advertising and marketing time period designed to indicate minimal intervention within the winemaking course of. In espresso, “pure” processing means one thing very particular: that the beans or seeds are dried inside the whole espresso fruit. This method differs from the “washed” (or moist) methodology, during which the beans are stripped of their fruit earlier than they’re dried. Each approaches have profound affect on the sensory character of the inexperienced espresso. As in winemaking, pure processing of espresso is a minimal-intervention course of in its most elementary kind.
However now, “primary” pure processing — which usually entails drying entire espresso cherries on concrete patios or display screen tables within the solar, raking and turning them usually to keep away from mildew and encourage even drying — is being pushed additional by farmers and mill operators seeking to distinguish and intensify their coffees. Their essential technique is including a fermentation step earlier than the espresso fruit is laid out to dry. The fermentation is being additional elaborated by including wine yeasts, conducting the fermentation in sealed tanks (the anaerobic methodology), freezing espresso fruit earlier than drying it, and different novel processing experiments. No matter you consider this development towards experimentation, it’s clear that it’s not a passing fancy. The extraordinary aromas now filling the Espresso Overview lab could also be the results of numerous processing wrinkles, however they share at the least one frequent denominator — the espresso cherries all have been dried in the entire fruit.

This month, we requested roasters to ship us natural-processed single-origin coffees they’ve roasted for espresso format. We acquired a variety of samples, from the basic to the wildly inventive. Of the ten coffees we overview right here, 5 are straight naturals, dried in the entire fruit with none further steps within the course of, whereas 5 are extra experimental, with added steps resembling anaerobic fermentation or fermentation with yeast added.
Specializing in single-origin coffees (versus blends) makes this an attention-grabbing inquiry as a result of it successfully eliminates the affect of mixing. Traditional espresso blends usually mix low-toned, chocolaty coffees with high-toned, fruity coffees, for instance, and there may be typically a broad spectrum of creativity within the mix element selections and their ratios. Right here, the roasters needed to work with what the inexperienced espresso supplied, in impact getting out of the best way besides, after all, for the essential acts of choosing the coffees and creating their roast profiles. One factor is obvious: Roasters who’re working with naturals are usually not afraid of massive fruit, which characterizes all of this month’s coffees.
Omni-Coffees Are Additionally In
And it’s in all probability not a coincidence that 9 of the ten coffees reviewed listed here are light- or medium-roasted. Only one, Simon Hsieh’s “Chasing Horizon” (95) is roasted to medium-dark, however darker roasts are Hsieh’s specialty and the main target of his firm’s model, in order that’s not shocking. The opposite roasters are working clearly inside the third-wave mannequin of lighter roasting. In any case, massive fruit and light-weight roasting have a tendency to offer totally different challenges for espresso, each within the straight shot and in milk drinks, and a few attention-grabbing spins emerged in our discussions with roasters. Aside from Hsieh’s Chasing Horizon and Hula Daddy’s Kona Pure Espresso, not one of the coffees reviewed this month is introduced on roasters’ web sites as completely for espresso; fairly, they’re supplied for unspecified brewing functions. So, whether or not you’re purchasing for coffees for pourovers or residence espressos, the roast profile you purchase is similar, basically making them “omni” coffees aimed toward working nicely in both format.
A Be aware About Acidity
Whereas Espresso Overview’s analysis format for coffees cupped for brewed or non-espresso functions consists of specific consideration of acidity, our espresso overview kind doesn’t immediate us to take acidity under consideration. You’ll discover acidity not directly referenced in our international descriptions that describe construction, resembling “sweetly tart,” “richly savory,” “gently herbaceous.” However the reality is that this month’s principally lighter-roasted naturals specific a transparent acidity that’s unmuted by deeper roast ranges, and it’s right here that one’s preferences could come into play. You recognize who you might be: If you happen to dig a brilliant acidity with juicy fruit entrance and middle, you’ll discover loads to like right here; for those who go to espresso primarily for spherical, chocolaty photographs, you could be dissatisfied. In different phrases, these are largely what we name caveat coffees, love or hate affairs, on this case due to their tendency towards the intensely brilliant fruit finish of the flavour spectrum. No matter your sensory camp or your attachment to it, nevertheless, these 10 coffees signify extraordinary expressions of single-origin natural-processed coffees, ranging in rating from 93 to 95.
5 Traditional Naturals
We overview 5 coffees which might be processed by the fundamental pure methodology, once more, merely dried in the entire fruit with each day care and a focus through the course of to make sure that the cherries dry evenly and cleanly.
Barth Anderson, of Barrington Espresso Roasting, whose “Supernatural” scored 95, says, “I usually gravitate to softly utilized natural-process coffees favoring delicate and elusive traits — not so the case with the Supernatural from Durato Bombe. With this espresso, I’m drawn to its straight-ahead utility of the pure course of. On our first go on the cupping desk at a really gentle roast, it jogged my memory of the shock I skilled after I tasted my very first pure. It was a blueberry powerhouse. What units it aside is the main target and refinement in its supply. I maintain its producers Asefa and Mulugeta Dukamo fully answerable for such finesse.
It’s heft, depth and ample chocolate make it a shoo-in for pushing the roast remedy into medium and showcasing it as a single-origin espresso. As anticipated, our shot trials proved to reinforce what we favored most about it on the cupping desk.” We additionally discovered this espresso to be as advanced as it’s intense, with watermelon sweet notes on the prime and savory leaning herb notes beneath. The chocolate is a throughline however not the espresso’s most distinguished characteristic, fairly it’s an built-in a part of the entire.
Roaster Jason Yang of Felala Espresso says he was drawn to “the depth and complexity of the flavors” of his Ethiopia Alemaza Pure (95), “accompanied by the acidity and sweetness inherent within the espresso, which creates a harmonious expertise.” He describes the problem of roasting this high-density inexperienced espresso, together with his resolution “to not contact second crack with the intention to preserve extra of the fruitiness and to maintain the stability of sweetness with the chocolate notes.” We picked up on the darkish chocolate notice, however discovered tart pomegranate, bittersweet blood orange zest, and wealthy sandalwood to be much more distinguished.
Kakalove Café’s Honduras Pure San Vicente Belarmino Contreras Pacas (94), whose berry-driven, richly floral course of we liked, attracted roaster Caesar Tu “due to the espresso’s well-known provenance, as San Vicente is a well-known washing station that has gained the Cup of Excellence many instances.” He provides that he appreciates the San Vicente mill’s deal with small farmers and number of processes. The San Vincente is particularly elegant, displaying pungent florals in each the straight shot and in milk alongside a mulberry-like purple fruit notice.
Simon Hsieh’s “Chasing Horizon” (95) is a mix of three Ethiopian naturals from the Guji and Yirgacheffe areas. Hsieh says that whereas these three coffees every have a special character, all of them share “a clear cup with out over-fermented taints.” He provides that, “One performs nicely in aroma and brightness, one performs an awesome winey/chocolaty position, whereas the final offers very engaging physique and aftertaste. Once they stand alone, they could lack sure strengths, however collectively they work with full energy.” We discovered this single-origin mix to be as floral as it’s chocolaty, with sweet-spicy hyacinth-like florals as its anchor.
Rounding out the basic naturals is Trendy Instances’ Ethiopia Guracho Pure (93), which is delicately berry-toned and richly candy, with notes of blackberry coulis, cocoa nib, agave syrup, cedar and creamy macadamia nut. It’s particularly fairly in cappuccino format, the place berry and cocoa notes stability wealthy fragrant cedar.
Roastery supervisor Seancarlo Ohlin says of this espresso, “We’ve all the time been big followers of pure Ethiopian coffees and have made it a focus of our espresso program. We sourced this espresso from Atlas Espresso Importers and have been working with them for various years. This espresso was sourced as a mixing element however instantly turned heads on the cupping desk. We determined it was nice as a single origin, and it tasted incredible on bar. Our espresso roasts typically have an prolonged roast improvement, however we determined to run our regular improvement for this single-origin espresso, and we’re completely happy we did! It’s bursting with juicy fruit traits that delightfully linger on the palate. Shout out to our head roaster Courtney Heald for mastering this roast!”
5 Naturals on Steroids — The Experimental Spectrum
Now to the experimentally processed naturals, additionally dried in the entire fruit however with an additional twist. These improvements are typically proprietary to producers (secret recipes, if you’ll), however every roaster shared a bit in regards to the methodology and the explanations they had been drawn to those coffees as espressos. Experimental processes of any form are often supposed to accentuate or spotlight a specific facet of the inexperienced espresso. Within the case of naturals, it’s often all in regards to the fruit, and often entails including a fermentation step earlier than the espresso fruit is dried.
Two of those coffees made the fermentation step anaerobic, that means the fermentation was performed in sealed tanks to get rid of oxygen and yeast fermentation whereas selling bacterial or lactic acid fermentation. The anaerobic step appeared to advertise depth and complexity when it comes to savory florals and different umami impulses, nuancing the fruit and sweetness.
Fortifying fermentation with numerous yeasts is one other new(ish) processing frontier and, once more, producers and their roaster companions usually choose to carry their playing cards shut so far as particular particulars go. However we all know that frequent experiments embody the addition of wine yeasts to the espresso fermentation. There may be all the time yeast current throughout fermentation, however the concept is that controlling the particular strains can produce extra favorable aroma and taste outcomes.
We are inclined to keep away from the time period “unique” as a result of it’s usually used within the context of cultural appropriation (i.e., categorically “different” in relation to our personal expertise, however maybe typical in another person’s). However it wouldn’t be inappropriate to make use of it to explain a few of these experimental coffees as, frankly, universally non-coffee-like. For a lot of producers working within the experimental realm, that is the purpose: to broaden a espresso’s sensory vary into the areas of tea, wine, even non-beverages like cheese or yogurt.
For a few years, we’ve adopted Hula Daddy Kona Espresso’s yeast fermentation experiments with espresso grown at its personal Kona farm. It’s solely only recently that roaster Laura Ross determined to begin working with roast profiles aimed toward espresso functions. This month’s Kona Pure Espresso (95) is richly chocolaty, sweetly nutty and subtly fruity. Wine yeasts added to a fermentation step appear to have intensified each aroma and taste.

PT’s Colombia Tres Dragones Pure (94) was processed by what producers Rigoberto and Rodrigo Herrera of Finca Potosi, recognized for his or her experience in fermentation, name a “hybrid pure” methodology, that means that the espresso was each fermented and dried in the entire fruit. Roaster Mike Mazulo says, “The Tres Dragones Pure, yr after yr, has continued to point out the care and dedication taken at Granja La Esperanza with this lot, as they do with all their espresso, all the time working to refine their processes. It has been successful yearly, each as espresso and brewed. I really like a pure espresso that’s dynamic as a single shot, in milk, or over a scoop of ice cream — it’s vibrant, candy, deep, wealthy, and sophisticated, with ripe to macerated fruit-forward taste and the physique to enhance. The eye to element in pure processing can actually spotlight the trouble of the farmers.” We skilled this espresso as winey and musky, richly chocolaty — satiating in its herbaceous, savory depth and fruity carry. It’s a great instance of the fragile candy ferment that may be achieved in espresso, barely and deliberately evocative of alcohol.
We additionally overview two anerobic natural-processed coffees, during which the entire cherries are fermented in an oxygen-free, hermetically sealed vessel earlier than drying, giving them an depth and depth that works nicely in espresso format. Paradise’s Colombia Quindio Anaerobic Pure (94) shows notes of tropical fruit (rambutan) and bittersweet citrus (kumquat) ensconced in deep chocolate notes. It is a espresso that we additionally just lately reviewed as a brewed espresso at 94. When cupped fairly than brewed as espresso, it displayed totally different dominant aroma and taste notes (hyperlink to overview). Roaster Miguel Meza says, “In a pure espresso for espresso, we search for fruit and intense distinctive flavors. This espresso appears to have cinnamon added to the fermentation, and we favored how that got here by means of in a shot of espresso, together with the sweetness and roundness of the mouthfeel from the anaerobic pure processing. We truly didn’t roast this espresso with espresso in thoughts; it’s a lighter roast supposed for filter use that simply occurred to make an attention-grabbing espresso, as nicely.” Whereas we didn’t detect the cinnamon notice, we did hone in on sandalwood, a equally spice-toned descriptor.

Travas Clifton, founding father of modcup espresso, feedback: “Every time we’re utilizing pure coffees for espresso, we wish to spotlight a element central to our branding: [the fact that] Espresso is a Fruit. Earlier than we speak about something in espresso, we should perceive that the bean is definitely a seed, a seed of an unbelievable flavor-complex fruit.” Within the case of modcup’s Fruit Bomb/Ethiopia Shantewene (93) the fruit is current and intense, with an attractive lean towards the savory and tart virtually definitely promoted by an anaerobic ferment step.
Maybe essentially the most uncommon processing methodology of all is represented right here by GK Espresso’s Colombia Finca Jardines del Eden Ice Fermentation Pure (94), whose processing concerned freezing the espresso cherries proper after harvest for 5 days, slowing the drying and rising the sweetness of the fruit. Roaster Gary Liao says that the revolutionary processing methodology resulted in a super-sweet espresso that impressed him to create an ice caffè latte with pudding for his café. He loves the profile for its winey presentation and dessert-like qualities.

Milk Is a Unusual Bedfellow
These 10 natural-processed single-origin coffees, examined as espressos, are all clear representations of their respective inexperienced coffees and their processing strategies, and every provides a strikingly divergent presentation in cappuccino format. With basic espresso blends, chocolate notes are inclined to dominate in milk codecs, however these naturals increase our sense of how espresso can play with milk, from the decadently floral and virtually over-the-top fruity to the extra conventional chocolaty and nutty, with a center floor of savory, herbaceous umami. Learn by means of the critiques to get a way of how these coffees construct on the notion of how a cappuccino can style when it’s a bit out of the field. Once more, one’s preferences will reign supreme, as they need to, however these coffees give us an opportunity to push our sensory boundaries in new and thrilling methods.
We hope you get pleasure from this foray into the unapologetically fruity realm of pure espressos, or at the least give a few of these a (pun supposed) shot.
