Tasting descriptors
Strawberry or peach describes a reported sensory impression. That wording alone does not establish an added ingredient.
From cherry to bean
EVERY WAY
COFFEE IS PROCESSED.
27 documented processing entries, from washed and natural to fermentation experiments and decaf. Each name describes a technique, not proof of a coffee’s exact recipe, flavor or added ingredients.
Contextual illustration of processing, not a photograph of a particular farm or lot.
What’s behind that flavor?
Use the exact lot’s source to identify what was disclosed. These categories can overlap; they are a reading guide, not a certification assigned to any coffee.
Fruit added during processing
Look for an explicit producer or roaster description of fruit, juice or pulp added during fermentation. Record the stage and the named input.
Added microbial culture
Yeast or another culture may be introduced during fermentation. Inoculation alone does not establish that another fruit was added.
Flavoring after roasting
Flavoring applied to roasted coffee is a separate practice. Record it only when the source documents that step.
Method undisclosed
When the ingredients or processing stage are missing, keep them unverified. A flavor note cannot fill the gap.
Read the processing and infusion reference ↗ · Ask who supplied the description and which lot and processing stage it covers.
What a processing label can and cannot tell you
Washed, natural, honey and anaerobic describe approaches, not flavor guarantees. Ask whether the roaster documents the producer, fruit removal, fermentation conditions, drying procedure and any added ingredients. A color label such as “black honey” is not a globally standardized recipe.
Is semi-washed coffee the same as pulped natural or wet-hulled? Not reliably. The term can describe pulped-natural-style drying in one origin, but in Indonesian coffee it can refer to wet-hulling. Without the producer’s actual steps, we preserve “semi-washed” as a reported label rather than claiming it proves pulped natural, wet-hulled or fully washed processing. Compare the Royal Coffee terminology guide with Cafe Imports’ wet-hulling explanation.
Similarly named methods are not necessarily identical. Our Thermal Shock guide and Thermo-Shock guide document different producer-reported protocols. Check the specific lot before treating either term as interchangeable with the other.
Background reading, not evidence for an individual coffee’s protocol:
Comparing experimental process labels
Fruit co-fermentation and a coffee-cherry starter are not automatically the same method. Cherry Reposado and Culture-Washed also require lot-specific documentation.
The old guard
Methods that built the trade
Widely used methods with different handling and drying steps. The labels are a starting point, not proof of any producer’s exact protocol.
01
Washed
Washed processing typically removes the outer fruit (depulping), then removes sticky mucilage through fermentation and washing or mechanical demucilaging before drying coffee in parchment. Some producers add a clean-water soak. The label does not specify the water used, fermentation time, equipment or final taste; these details vary by mill and lot. A producer protocol is needed before making precise claims about the method.
Possible tasting notes, not a prediction
Can show crisp acidity and distinct origin character, but flavor and quality depend on the coffee and execution.

01
Natural
In natural (dry) processing, the coffee cherry is dried with skin and pulp intact around the seeds, often on raised beds or patios. Producers sort, turn and monitor the drying fruit to manage moisture and defects. Microbial activity can take place during drying, but handling varies by producer. The word natural describes the fruit-on drying approach; it does not establish added fruit, a particular fermentation protocol or guaranteed berry and wine notes.
Possible tasting notes, not a prediction
Fruit-forward or fuller-bodied cups are possible, not guaranteed; careful drying and the starting coffee matter.

01
Wet-Hulled
Wet-hulling, known in Indonesia as giling basah, removes the parchment while the coffee is still substantially wetter than a fully dried green coffee bean, often around 30–35 percent moisture at hulling in documented examples. The exposed seed then undergoes further drying. This differs from washed coffee, where parchment ordinarily remains in place until the seed is dried. The method is associated with Indonesia's humid growing regions, but its name cannot guarantee an earthy profile, low acidity or a specific quality grade. Ask the mill for hulling moisture and drying practices.
Possible tasting notes, not a prediction
Some Sumatran lots are earthy or full-bodied; these are examples, not guaranteed outcomes.

Monsooned
Monsooning is a post-harvest conditioning process practiced on India's Malabar coast. The exporter Aspinwall describes exposing already processed coffee beans to humid southwest-monsoon air in ventilated warehouses, repeatedly spreading, raking and loosely bagging them while monitoring moisture and mold risk. Its documented workflow lasts about 12–16 weeks; the beans may swell and become pale yellow. This is not drying intact fresh cherries in the natural process. The historical shipping story and regional label do not establish the protocol for an individual lot.
Possible tasting notes, not a prediction
Exporters describe a mellow, lower-perceived-acidity style, but flavor and quality still vary by lot.

01
Pulped Natural
Pulped natural describes coffee with the cherry skin and much of its pulp removed before drying, while some mucilage remains on parchment-covered seeds. Especially associated with Brazil, the method overlaps in everyday terminology with semi-dry or honey processing, and local practice differs. The label does not specify a fixed retained-mucilage percentage, fermentation duration, water use or cup flavor. Ask how that particular producer pulped, dried and monitored the lot.
Possible tasting notes, not a prediction
Sweetness, body and fruit-like impressions vary; they cannot reliably be ranked between washed and natural from the label alone.

01
Mechanically Washed (Demucilaged)
Mechanical demucilaging removes some or most sticky mucilage from depulped parchment coffee with specialized equipment, rather than relying entirely on an extended fermentation-and-wash cycle. Some machines still consume water, so 'mechanically washed' does not mean water-free. A published 2022 small-machine trial measured reduced processing time and water use in its specific setting; those savings and levels of bean damage are not universal specifications. The label does not prove zero fermentation, any precise mucilage-retention level or a particular flavor.
Possible tasting notes, not a prediction
No inherent tasting-note guarantee; results depend on the complete post-harvest process, coffee, roast and brew.

01
Post-Wash Soak (Kenya-Style)
A separate clean-water soaking step after washing and grading coffee parchment, documented at some Kenyan washing stations. Kenya's coffee sustainability manual describes soaking selected parchment grades overnight before moving them to drying tables; the water and duration depend on the mill. This step should not be confused with the earlier fermentation or washing. Its presence does not prove that particular compounds were removed or that the finished coffee will have higher acidity. Ask whether the specific lot received a post-wash soak and for how long.
Possible tasting notes, not a prediction
A clean or bright cup is possible, but post-wash soaking is not proof of those flavors.

The honey ladder
Honey processing has many styles
Honey is a method with styles such as yellow, red and black. Mucilage retention and drying vary by producer; colors are not standardized recipes or guaranteed flavors.
02
Honey
Honey processing removes the cherry skin but leaves some sticky fruit mucilage on the parchment during drying rather than fully washing it away. No actual honey is required. Labels such as yellow, red and black honey commonly refer to differences in mucilage handling and drying, but they are not standardized recipes across farms. Shade, turning and moisture control influence the result. The name does not independently prove sweetness, origin, ingredient additions or a specific cup profile.
Possible tasting notes, not a prediction
Sweet or fruit-like impressions may occur; the label alone cannot predict the cup.

Method references linked in guide
02
White Honey
White honey usually refers to a honey-process coffee that retains relatively little fruit mucilage on the parchment during drying. The amount removed, use of mechanical demucilaging, and drying conditions vary by producer. The color name is not a standardized percentage or a flavor guarantee. Ask how much mucilage was retained and how the coffee was dried. The term does not mean that bee honey was added.
Possible tasting notes, not a prediction
A relatively clean cup is possible, but sensory outcomes depend on the lot and how it was processed, roasted and brewed.

02
Yellow Honey
Yellow honey is a producer-used variation of honey processing. After the cherry skin is removed, some mucilage remains on the parchment during drying; yellow styles are often managed with less shade and faster drying than darker honey styles. The exact percentage of mucilage, duration and appearance are not universally standardized. Ask for the farm's actual depulping, demucilaging and drying protocol rather than treating yellow as a precise technical specification. No bee honey is required.
Possible tasting notes, not a prediction
A lighter or cleaner sensory impression is possible, but the label does not predict sweetness, acidity or quality.

02
Red Honey
Red honey is a producer-defined honey-processing style: the cherry skin is removed, some mucilage remains while the parchment dries, and partial shade or slower drying may contribute to its reddish appearance. There is no universal rule that red honey must retain exactly half its mucilage. Shade, humidity, turning and local practices differ by farm. To understand any particular lot, check the actual mucilage-retention and drying protocol. Red honey does not mean bee honey was added.
Possible tasting notes, not a prediction
Fruit-like sweetness or a fuller body may occur, but these impressions must be confirmed by tasting, not inferred from the color label.

Method references linked in guide
02
Black Honey
Black honey is a darker honey-processing style, often involving more mucilage left on parchment and slower drying or added shade. The specific mucilage amount, drying duration and conditions vary by producer; the name is not a universal technical standard. Careful drying management helps avoid mold and unwanted fermentation. For a given lot, verify the farmer's drying protocol rather than assuming a fixed percentage or a guaranteed flavor. Bee honey is not an ingredient implied by this name.
Possible tasting notes, not a prediction
Some coffees show fuller body or fruit notes; the label does not guarantee either or establish quality.

02
Anaerobic Honey
Anaerobic honey combines an oxygen-limited fermentation stage with honey-style drying in which some fruit mucilage remains on the parchment. Some producers ferment depulped coffee in sealed vessels before drying, but the order, duration, temperature, fruit handling and use of cultures vary. The label neither means that honey was added nor guarantees extra sweetness or a specific aroma. For a given lot, ask which stage was anaerobic and whether any fruit or other ingredients were introduced.
Possible tasting notes, not a prediction
Possible fruit or sweetness impressions; no specific flavor is guaranteed by the processing label.

The fermentation era
Where coffee's new frontier lives
Producers experiment with fermentation time, temperature, microbial cultures and oxygen exposure. A process label alone does not prove a particular tasting note.
03
Anaerobic
Anaerobic coffee includes a fermentation stage in a sealed or oxygen-restricted environment. Producers may ferment intact cherries or depulped coffee, then finish using natural, washed or honey processing. Time, temperature, vessel, microbial cultures and any added ingredients vary widely. The term identifies a fermentation condition, not a single universal recipe. It cannot by itself establish an exact flavor, fermentation organism or quality level.
Possible tasting notes, not a prediction
Some lots are fruit-forward or wine-like; others are not. Sensory outcomes require tasting and lot-level evidence.

Carbonic Maceration
Carbonic maceration adapts a carbon-dioxide-rich fermentation technique from winemaking to coffee. Producers hold coffee cherries in a vessel supplied with CO₂; fruit condition, oxygen availability, pressure, temperature, duration and subsequent drying or washing vary by lot. A 2023 study on Yellow Caturra found that fermentation duration influenced physical and sensory outcomes, including trade-offs at longer durations. That experiment cannot establish one universal flavor profile or verify the exact gas, microorganisms, additives or pressure used for unrelated coffees. Ask for a documented producer protocol.
Possible tasting notes, not a prediction
Fruit-like or wine-like notes may occur, but carbonation, precise acidity and cup quality cannot be inferred from the label.

03
Lactic Fermentation
Lactic fermentation describes a coffee protocol designed to favor lactic-acid bacteria, sometimes using a selected starter and sometimes controlled conditions. Such bacteria can metabolize sugars and produce lactic acid, but the outcome depends on strain, temperature, oxygen, duration and the coffee itself. The label does not establish an exact acid level, a specific flavor or the addition of dairy ingredients. Ask whether cultures were added and what process measurements the producer recorded.
Possible tasting notes, not a prediction
Some lots are perceived as round or creamy; this does not prove milk was added or predict other lots.

03
Koji Fermentation
Koji fermentation is an experimental coffee process using selected Aspergillus oryzae cultures, familiar from Japanese food production. Producer interviews describe tests with koji applied to coffee cherries, with results compared against other processing methods. The label does not tell us the culture dose, fermentation length or drying method, and one experimental result cannot establish flavor changes for all coffees. Ask for the producer's specific method and documented controls.
Possible tasting notes, not a prediction
Reported mouthfeel and aroma changes are experimental, not guaranteed for every lot.

03
Yeast-Inoculated Fermentation
Yeast-inoculated fermentation means a producer deliberately introduces a selected yeast culture during post-harvest processing. Results depend on the particular strain, dose, time, temperature, oxygen conditions and coffee. Research shows sensory outcomes can change, but a selected yeast does not guarantee sweetness, fruitiness, greater consistency or a higher quality score. Ask which starter culture was used and whether the producer documented the process.
Possible tasting notes, not a prediction
Lot-specific; selected yeast can change flavor without guaranteeing a particular sensory profile.

Fruit Co-Fermentation and Coffee-Cherry Starter
This entry covers two labels that should not be confused. Fruit co-fermentation introduces fruit or fruit-derived material other than coffee cherries during processing. Mosto generally means fermented coffee-cherry juice or processing liquid used to seed another lot; it does not alone prove that outside fruit was added. Recipes vary. Additions may affect flavor even when removed before roasting. Ask the producer which fruits, liquids or cultures were introduced and at which stage.
Possible tasting notes, not a prediction
Flavor must be assessed at the lot level; neither label is a reliable flavor prediction.

Thermal Shock
Thermal shock is a temperature-management technique, not a single standardized processing recipe. The Coffee Quest documents a specific Finca El Paraíso Red Plum protocol with controlled fermentations followed by washing at 40°C and then 12°C before drying. Those temperatures and steps are an example, not rules for every lot. The producer's proposed mechanism of flavor-compound retention is not independent proof for all coffee. The label alone does not establish sterility, ingredient use, exact fermentation steps or a guaranteed flavor.
Possible tasting notes, not a prediction
Lot-specific. Reported floral and fruit-like notes are observations, not a guaranteed consequence of thermal shock.

Double & Sequential Fermentation
This umbrella label describes coffee fermented in two or more deliberately differentiated stages. A producer might change the vessel, available oxygen, selected culture or other condition between stages. The name alone does not specify the sequence, length, fruit state or drying step. Multiple stages do not automatically create more complex or higher-quality coffee. Ask the producer to describe each stage in order and to disclose any added ingredients.
Possible tasting notes, not a prediction
No reliable general flavor prediction; sensory outcomes need lot-level evidence.

03
Extended Fermentation
Extended fermentation means fermenting coffee longer than a producer's usual reference protocol; it is not a globally standardized number of hours. Results depend on the coffee, culture, oxygen, temperature, hygiene and drying. Longer fermentation does not automatically improve quality or guarantee fruit or wine-like flavors. Ask the producer for the actual duration and monitored conditions.
Possible tasting notes, not a prediction
No universal flavor outcome. Lot-level tasting and documented protocol are essential.

Culture-Washed (Starter-Culture Washed)
Culture-washed is an experimental starter-culture washed process documented for the Kamogo coffee from Cahoots Coffee at Kapyoma Washing Station in Uganda. September Coffee credits a protocol described by Pranoy: coffee cherries are submerged to cultivate a native microbial starter; the cherries are removed and the active liquid is introduced to freshly depulped coffee. For the documented Kamogo lot, the producer reports roughly 18 hours of fermentation, grading-channel washing, drip-table resting and around three weeks of parabolic solar drying. These are lot-specific reported details, not a universal formula. The phrase 'dry washed' is not established by this source as a synonym. Ask for the actual starter, duration and drying records for other lots.
Possible tasting notes, not a prediction
September Coffee reports fig, date and almond impressions for its Kamogo release; these are that roaster's observations and cannot be generalized.

Taking the caffeine out
Decaffeination, done honestly
Two documented decaffeination approaches, not an exhaustive market survey. Pressurized CO₂ and other decaffeination processes also exist.
04
Swiss Water Decaffeination
Swiss Water is a branded water-based decaffeination process for green coffee. Beans contact green coffee extract containing coffee solubles but little caffeine. Caffeine moves into the liquid and is captured by activated-carbon filters; the beans are subsequently dried. The company reports 99.9% caffeine removal from green coffee, not a guarantee of zero caffeine in a brewed cup. The process aims to retain the original coffee's characteristics but cannot promise an identical flavor. Verify that a lot actually used the Swiss Water process.
Possible tasting notes, not a prediction
Depends on the original coffee, roast and brew; neither smoothness nor flavor preservation is guaranteed.

Sugarcane (Ethyl Acetate) Decaffeination
Sugarcane or EA decaf uses ethyl acetate to extract caffeine from hydrated green coffee. In documented Colombian operations the ethyl acetate comes from sugarcane byproducts; verify the source for a specific lot. The extraction liquid is removed, and the beans are treated and dried. Ethyl acetate is a solvent even when plant-derived. Sugarcane does not mean sugar is added to the coffee, and the name does not establish sweetness or cup quality. Ask the roaster for the facility and method used.
Possible tasting notes, not a prediction
Lot-dependent; the word sugarcane is not evidence of added sweetness or flavor.

Cherry Reposado
Cherry Reposado is a producer-defined processing label used for the Catuai Macho release from Finca Macho / Santa Rosa 1900 in Costa Rica. Verve Coffee identifies the lot as Cherry Reposado but does not publish the detailed resting, fermentation, depulping or drying sequence. This is not an industry-standard method with a verified fixed protocol. Do not assume it means anaerobic, honey, or natural processing; ask the producer or roaster for the exact cherry handling and drying steps.
Possible tasting notes, not a prediction
Verve describes plum, black tea and dark-chocolate impressions for its Macho lot. Those are roaster tasting notes, not independently verified or universal outcomes.

Thermo-Shock
Thermo-Shock is a producer or roaster label for temperature-managed coffee processing, not a universally fixed recipe. Klatch Coffee describes a Finca Las Flores Bourbon Ají lot with 12 hours of cherry oxidation, hot-water exposure at 50°C before an 80-hour oxygen-restricted fermentation, then dehumidified drying. This differs in sequence from Finca El Paraíso's documented warm-then-cold washing step after fermentation. Those are two specific producer-reported protocols, not proof of distinct universally standardized categories. Claims about locking in flavors or changing cell structure should not be treated as independently established for all coffee.
Possible tasting notes, not a prediction
Klatch reports rose, spearmint and white-cherry impressions for its specific Bourbon Ají lot; no flavor is guaranteed in other lots.
