Below is an extended list at common phrases and coffee terminology used within the industry. We will be constantly updating this information, so be sure to check back.

 

AA

Letters used to grade quality of a coffee bean. Kenya AA coffee beans, for example, pass through Grade 18 (18/64" diameter) sieve perforations, but are too large to pass through Grade 16 (16/64" diameter) sieve perforations.

 

Acidity

The sharpness, snap, sourness, or liveliness of coffee.

 

Acrid

A harsh sour taste. An acrid coffee can be described as tart, sharp, or acerbic.

 

Afterburner

A device that heats the exhaust air from a roaster in order to destroy particulate and odors.

 

Air Roaster 

An air roaster, or fluid bed roaster, is a machine that uses fast streams of hot air to roast coffee beans. There are different types, or configurations, of air roasters, but all use hot air to convectively roast the beans and to help keep the beans moving. Most commercially available coffee is either air roasted or drum roasted.

 

Alkaloid

Any of a group of organic, nitrogenous compounds that are physiologically active and usually bitter. The taste term "alkaline" describes a dry taste sensation mostly at the back of the tongue. While somewhat bitter, an alkaline taste is not necessarily disagreeable and is characteristic of many dark roasts and some Indonesian coffees.

 

Altura

Means "heights" in Spanish and is used to describe high altitude or mountain-grown coffee.

 

American Roast

A light medium roast, the traditional roasting norm for North America. Also called "Brown Roast".

 

Aquapulp

Terms for a procedure in which the sticky fruit pulp, or mucilage, is removed from freshly picked coffee beans by scrubbing in machines.

 

Antesia

Damage from the Antestia bug, resulting in coffee beans ranging from slightly discolored to almost entirely black and shriveled up.

 

Arabica or Coffea Arabica

Coffea Arabica trees produce nearly all of the worlds specialty coffee. The vast majority of coffee is Robusta or Arabica. There are at least a dozen variations, or cultivars, of the Coffea Arabica tree. These include: Typica, Bourbon, Caturra, Catuai, Pache Comum, Pache, Catimor, Kent, Mundo Novo, Maragogype, Amarello, and Blue Mountain. Geisha is the oldest known Arabica.

 

Aroma

A quality that can be detected by the olfactory system.

 

Artisan Coffee

Coffee produced by skilled Roasters using high quality coffee beans from all over the world using both Robusta and Arabica. Accurate, good roasting equipment is also a requirement to create Artisan Coffee.

 

Ashy

Coffee odor similar to that of an ashtray or fireplace. An "Ashy" aroma indicates a dark roast, and is not necessarily a negative attribute. Ashy coffees generally have a carbon-like flavor.

 

Astringent

Causing the mouth to pucker or feel dry upon ingestion.

 

Baggy

A taste characteristic of coffee stored too long in burlap (jute) bags, causing the coffee beans to acquire a straw-like coffee bag flavor. Also used to describe light roasted coffee with mildewy qualities.

 

Baked

Flat, dull, and uninteresting coffee. A baked flavor may be caused by roasting too slowly. Coffee roasted in a drum roaster for much more than about 17 minutes will likely be burnt or have a baked flavor.

 

Balance

Term used to describe coffees to which no particular flavor overwhelms others but has enough flavors to be interesting or complex.

 

Bar Pressure

An Espresso machine uses nine to ten Bars of pressure to force hot water through finely ground coffee when making espresso. A Bar is equal to 14.5 PSI, or roughly the pressure of one Atmosphere.

 

Barista

An Italian term for an experienced or skillful bar operator. In Italy, a Barista typically serves different varieties of beverages including coffee and alcoholic beverages.

 

Batch Roaster

Batch roasters produce a fixed quantity (lbs per batch) of roasted beans at a time. In a batch roaster, the beans are removed before roasting the next batch. Continuous roasters produce roasted coffee at a fixed rate (lbs per hour).

 

Beneficio

A coffee mill where harvested cherries are processed and sorted before final bagging for export. Beneficio means benefit, or profit, in Spanish. Traditionally, a Beneficio was the local mill where farmers brought ripe cherries for processing. Increasingly, farmers are installing their own mills or Beneficios.

 

Bird Friendly

Used to describe coffee grown in a shade canopy rather than in full sun. Shade grown coffees create habitats needed for migrating songbirds, are easier on the environment, and arguably create higher quality coffee.

 

Bitter

Having a sharp, pungent taste.

 

Black Beans

Black, or very dark, unroasted beans. Black beans typically result from harvesting immature cherries or by harvesting dead cherries that fall naturally from the tree. Black beans can also result from exposure to water and heat and insect-damage. Unroasted coffee beans with more than 25% black, deep blue, or dark brown surface area, may be considered black beans. Black beans have a detrimental effect on coffee taste. The number of black beans in a representative sample is a basic measure of coffee grade.

 

Blade Grinder

A coffee grinder that uses spinning blades to turn whole bean coffee to ground coffee. A blade grinder is simple and effective, but will produce an inconsistent particle size, or grind, compared to a bur grinder.

 

Blend

Usually refers to a mixture of two or more single-origin coffees. Sometimes the blend may contain other ingredients including flavorings, herbs, roots, or teas.

 

Blotchy

Irregular greenish, whitish or yellowish patches on unroasted coffee beans. Blotchy beans may result from incomplete or uneven drying during processing.

 

Body

A beverage’s weight or fullness a perceived in the mouth like a sensation of heaviness, richness, or thickness and associated texture. Body, along with flavor, acidity, and aroma, is one of the principal categories used by professional tasters cupping, or sensory evaluation of coffee.

 

Boiler

A pressure tank used to make hot water or steam, found in most espresso brewing machines.

 

Boulders

The largest coffee grounds in a particle size distribution.

 

Bourbon

A botanical variety of Coffea arabica. Bourbon first appeared on the island of Bourbon, now called Réunion, located in the Indian Ocean. Coffee produced from the Bourbon cultivar of the Coffea Arabica tree, was named after Bourbon Island where it was first cultivated. Bourbon Island was later renamed Reunion and is located east of Madagascar in the Indian ocean. France introduced the Bourbon cultivar to Africa and Latin America. Bourbon became the second most commercialized Arabica variety after Typica. Both the Typica and Bourbon varieties of Arabica are produced in large quantities throughout the world, but are slowly being replaced by more productive and disease resistant varieties such as Caturra. The Bourbon variety is bright yellow when ripe.

 

Bready

A bread-like, or grain-like, aroma. Insufficiently roasted, sour tasting, coffee will often have a bready aroma. Bready coffees may also be described as "green" or "beany."

 

Brine-like

A salty taste often caused by continuously heating coffee after brewing is complete. Brewed coffee that sits on a burner overnight is likely to taste briny.

 

Brew

Any method of making a coffee beverage from fresh water and roasted coffee grounds.

 

Brown roast

A light medium roast, the traditional roasting norm for North America. Also called "American Roast."

 

Bullhead

An extra large coffee bean. Sometimes a peaberry which has not totally grown together.

 

Burlap

A woven fabric made from fibers of the jute plant.

 

Burr grinder or Burr mill

Coffee grinder with two discs that grind coffee that can be adjusted. A burr grinder, or burr mill, uses rotating flat to conical metal disks with sharp ridges, or burrs, to evenly grind the coffee beans. A burr grinder is typically adjustable from very fine to coarse and produces a consistent particle size compared to the simpler blade grinder. Consistent particle size is important in brewing quality coffee, making burr grinders the choice of coffee professionals.

 

Canephora

Botanical name for a Robusta coffee tree variety. Robusta trees are "robust", meaning they are less susceptible to pests and disease and yield more coffee crop. Because of its ability to resist pests and disease, Coffea Canephora is the dominant coffee species grown at low elevations. Native to sub Saharan Africa. Robusta is the second-most-planted coffee species and yields coffee with approximately double the caffeine of arabica coffee.

 

Caramelization

A complex series of sugar-browning reactions that creates numerous new compounds.

 

Carbonization

The formation of carbon from an organic substance by pyrolysis.

 

Catalytic oxidizer

An afterburner that uses a precious-metal catalyst to clean roasting exhaust at relatively low temperatures.

 

Cellulose

A polysaccharide that is the main constituent of plant cell walls.

 

Chaff or Silver Skin

Part of the husk of the coffee seed released as beans expand during roasting.

 

Charge

Cherry

The fruit of a coffee tree which contains the coffee seed or green bean.

 

Chicory

Root of the endive which is sometimes roasted, ground, and added into blended coffees.

 

Chlorogenic acid

A polyphenol and antioxidant found in high concentration in coffee beans.

 

Cinnamon roast

The lightest commercial roast product by dropping the beans during early first crack.

 

City roast

A light roast, terminated during the latter stages of, or just after, first crack.

 

Coffee Berry Borer

The Coffee Berry Borer, or Hypthenemus Hampei, is one of the most significant pest problems for coffee farmers. The CBB is a black, two millimeter long, beetle that bores holes through the seeds coffee cherries. "Broca" is the widely used Spanish term for the coffee berry borer. CBB damage is also called "Broca damage".

 

Coffee Leaf Rust (CLR)

Coffee Leaf Rust is a disease caused by fungus afflicting coffee plants and first became a problem for coffee farmers in Sri Lanka in the 1860s. CLR has since spread to every coffee growing region of the world, and it destroyed Brazil's crop in 1970 as it did previously on the Islands of Java and Sri Lanka nearly a century before. Many affected plantations replaced their Arabica trees with more disease resistant Robusta. Some affected coffee producing countries have since began replacing the now less desirable Robusta trees with newer Arabica cultivars that are more disease resistant compared to the "heirloom" classics Typica and Bourbon. CLR is often prevented by the use of copper-based fungicides. The use of chemicals to prevent this, and other crop damages by fungus or pests, can sometimes take away certifications such as Organic.

 

Coffee-roasting machine

A specialized oven that transfers heat to coffee beans in a stream of hot gas while continually mixing the beans to ensure they roast evenly.

 

Cold-Water Method or Cold Brew

Brewing method in which ground coffee is soaked in a proportionally small amount of cold water for 10 to 20 hours. The grounds are strained out and the resulting concentrated coffee is stored and mixed with hot water as needed. The cold water method produces a low-acid, light-bodied cup that some find pleasingly delicate or easier to digest, but others may find bland.

 

Conduction

The transfer of heat from one substance to another by direct contact.

 

Continuous roaster

A high-yield roaster in which axial position, not time, determines bean temperature. Such roasters receive, roast, and discharge beans in a constant stream as opposed to in batches.

 

Convection

The transfer of heat by movement of a fluid.

 

Crema

The usually pale, antioxidant-rich, foam which covers the surface of coffees brewed into espresso or using other methods, like the french press. The color, amount, and dispersion of crema can dictate quality, roasting time, and freshness of coffee. It may also indicate the skillfulness of a barista.

 

Creosote

A brown, oily liquid mixture of phenols and other organic compounds deposited in the exhaust ductwork of a coffee roaster.

 

Crushed

Crushed coffee beans are most commonly the result of improperly set or damaged pulping equipment. Coffee beans can also be crushed during mechanical separation of the beans from the husk, or during mixing in fermentation tanks.

 

Crust

The layer of saturated coffee grounds that floats to the surface when cupping (tasting) coffee. As part of the traditional coffee cupping method, called "breaking the crust", the grounds are agitated to release trapped vapors allowing the cupper note the coffees unique characteristics. The crust is then scooped out with a spoon before tasting the brewed coffee.

 

Cupping

A systematic, somewhat standardized, method of evaluating coffee.

 

Dark roast

A smoky, bitter roast produced by discharging beans after the onset of the second crack.

 

Decaffeinated Coffee or Decaf Coffee

Coffee in which the caffeine has been extracted during the green bean stage by the bean using one of the following methods: European, Traditional, Swiss Water Processed, Mountain Water, or using the carbon dioxide method. The direct solvent method involves treating the beans with solvent, which selectively unites with the caffeine and is removed from the beans by steaming. The indirect solvent or solvent-water method involves soaking the green beans in hot water, removing the caffeine from the hot water by means of a solvent, and recombining the water with the beans, which are then dried. Both processes using solvents often are called European Process or Traditional Process. The water-only method, commonly known by the proprietary name Swiss Water Process or Mountain Process, involves the same steps, but removes the caffeine from the water by allowing it to percolate through a bed of activated charcoal. In the carbon dioxide method, which is only beginning to be established in the specialty-coffee trade, the caffeine is stripped directly from the beans by a highly compressed semi-liquid form of carbon dioxide.

 

Desorb

To cause the release of a substance from a surface.

 

Development

The degree of breakdown of a roasted coffee bean’s cellulose structure.

 

Disease

Disease refers to any disease that might afflict a coffee tree plant. There are many coffee plant diseases that can damage a coffee crop, but most are caused by fungus (mold). The most prevalent coffee mold problems are Coffee Leaf Rust (CLR), which shows as yellow-orange blotches on the leaf, and Coffee Berry Disease (CBD), which lives in the bark of the tree and produces spores that attack the coffee cherries. CLR, CBD, and Coffee Berry Borer (CBB) are significant disease and pest problems facing the worlds coffee farmers. Often, the use of chemicals are needed to treat these conditions in order for the farmers to save their crop but unfortunately will lose the Organic certification because of this.

 

Direct/Indirect solvents

Used during the decaffeination process, solvents used are usually methylene chloride and ethyl acetate, but have also included in the past solvents such as benzene, trichloroethylene (TCE), dichloromethane and even chloroform.

 

Doser

A spring-loaded device on commercial coffee grinders that serve a single serving of coffee grounds for brewing.

 

Double drum

A coffee-roasting machine with a drum made of two concentric layers of metal separated by a gap of several millimeters wide.

 

Double picked

A term describing when coffee cherries are handled by hand twice, once when being picked off the tree and again when sifting for impurities such as imperfect beans, pebbles or other foreign matter.

 

Drop

To discharge beans from a coffee-machine.

 

Drum roaster

A coffee-roasting machine in which the beans are tumbled in a rotating, cylindrical drum. A drum roaster roasts coffee in batches and uses a drum to hold the roasting coffee. As the drum spins, hot gasses transfer heat to the drum and the drum conductively heats the tumbling coffee beans. Some drum roasters have perforated drums that allow hot gasses to pass through the drum and convectively heat the roasting coffee. Most commercially available coffee is either air roasted or drum roasted.

 

Electrostatic precipitator

A device that removes particulates from coffee-roasting exhaust by using a high-voltage electrostatic charge to cause the particles to stick to charged panels.

 

Elephant Beans or Ears

An cluster of two or more deformed beans that grew closely locked together, but sometimes separate during processing or roasting. Also called "ears", due to their often ear-like appearance.

 

Endothermic

A reaction requiring the absorption of heat energy.

 

Environmental temperature

The air temperature in a roasting machine.

 

Exothermic

Releasing heat.

 

Espresso

Used to describe both a roast of coffee and a method of brewing in which hot water is forced under pressure through a compressed bed of finely ground coffee. In the largest sense, it can refer to an entire approach to coffee cuisine, involving a traditional menu of drinks, many combining brewed espresso coffee with steam-heated, steam-frothed milk.

 

Estate-Grown Coffee

Coffee produced by a single farm, mill, or group of farms.

 

Facing

Surface burning of a coffee beans, occurs late in a roast.

 

Faded

Unroasted coffee beans that have lost much of their original color, a characteristic of old crop and beans that were dried too rapidly. Processed coffee beans will slowly fade from green to pale yellow, if stored too long before roasting. Also called "soapy" or "bleached".

 

Fair trade coffee

Coffee that has been purchased from farmers at a "fair price" as deemed by international agencies. Fair trade pricing does not necessarily apply to all the farm workers involved in producing the coffee nor does it imply that the price provides the farmers a livable wage.

 

Ferment

A green-coffee defect that is the result of chemical breakdown by microbes. Coffee allowed to ferment too long during wet processing. After de-pulping coffee cherries to remove the skin and some of the pulp, the separated seed will still have a significant amount of pulp attached. The remaining pulp can be loosened by fermentation, allowing it to be washed away before drying. If fermentation is not stopped as soon as the remaining parchment is no longer slimy, and has a rough texture, the coffee may acquire oniony or soury flavors.

 

Fines

Tiny cell-wall fragments produced by grinding coffee beans.

 

Filter method

Method of brewing coffee through a filter that separates the coffee grounds from the brewed coffee. Also known as drip coffee.

 

First crack

A phase of coffee roasting characterized by loud, popping noises created by the release of pressure and water vapor from the inner beans. The first of two distinctly different periods of cracking sounds during a roast, when the coffee beans are giving off their own heat and expanding suddenly. "first crack" begins at bean probe temperatures around 400 degrees Fahrenheit, making a sound similar to popcorn, and then diminishes, and sometimes stops momentarily, before the start of "second crack". "Second crack" begins at bean probe temperatures around 440 to 450 degrees Fahrenheit. The darkest of palatable roasts (Dark French) is attained at the peak of "second crack". If the roast is allowed to continue to completion of "second crack", the coffee will be burnt and may catch fire.

 

Foxy

Unroasted coffee beans with a brown or rust color. Foxy beans may result from faulty fermentation, improper washing, over drying, or by harvesting over-ripe cherries. Also called "brown".

 

Flavor

The combined sensation of a substance’s taste and aroma.

 

Floaters

Coffee cherries that float in water and are 'floated-off' during wet-processing. Underripe, dried, damaged, or deformed coffee cherries tend to float and are discarded at the beginning of wet processing. Also called "lights".

 

Fluid-bed roaster

A drumless coffee-roasting machine in which beans are rotated and held aloft by a stream of hot gases.

 

Full city roast

A medium roast dropped just before, or just after, the onset of second crack.

 

French Press

Brewing method that separates spent grounds from brewed coffee by pressing them to the bottom of the brewing receptacle with a mesh plunger.

 

Froth

The process of making froth, or velvety hot foam, from milk using the steam wand of an espresso machine. A Barista skillfully uses the steam wand to draw air into the milk until the mixture reaches 155 to 165 degrees Fahrenheit and the foam becomes thick and velvety.

 

Green coffee or Green bean

Term describing the coffee seed from a ripened cherry prior to roasting.

 

Gourmet Coffee

Sometimes called "specialty" or "premium" coffee, gourmet coffees are made from exceptional coffee beans. Gourmet coffees have distinctive flavors, specific to botanical variety, processing method, and the unique characteristics of the soil and environment that produces them.

 

Grind

The particle size of ground coffee. The recommended grind depends on brewing method. The grind should be adjusted to create the desired amount of coffee extraction. The finer the grind, the quicker coffee can be extracted. Too much coffee extraction will remove unwanted chemicals and make the coffee taste bitter, while too little extraction will cause the coffee to taste flat and watery. Finely ground coffee has more surface area than coarsely ground coffee which allows for quick extraction, but the increased surface tension will not allow water to pass through the grounds by gravity. Espresso machines force hot water through very finely ground coffee at eight to ten times atmospheric pressure (8 to 10 Bars) to quickly make coffee that is neither under-extracted or over-extracted. Experience has found that with an espresso machine, optimum flavor is achieved by adjusting the grind so that a 1.5 ounce shot glass fills in about 25 seconds. A medium grind is used for filter-drip coffee machines and a coarse grind is used for brewing with a French Press. The finest of all grinds is the powdery Turkish Grind, used to make Turkish Coffee.

 

Hermetic

Refers to airtight containers used to store roasted coffee.

 

High-yield roaster

A very fast coffee-roasting machine that preserves an unusually high proportion of coffee’s moisture and organic matter. Italian roast The darkest commercial roast, which produces bitter, pungent, acrid coffee.

 

Kona

An arabica coffee grown specifically in Hawaii, USA and is considered to be a gourmet coffee because of rich volcanic soil conditions.

 

Maillard reactions

Chemical reactions between amino acids and reducing sugars that contribute to coffees brown color and roasty flavors.

 

Malty

The aroma of malt. Often used together with Cereal and Toast-like to include the aroma of cereal, malt, and toast. "Cereal", "Malty", and "Toast-like" describe grain-like aromas and flavors of roasted grain (including roasted corn, barley, or wheat), malt extract, freshly baked bread, or toast.

 

Manometer

An instrument that uses a column of liquid to measure pressure.

 

Medicinal

The smell of medicine, or iodine. A medicinal flavor with notes of iodine which can result from cherries drying while still on the coffee plant. Medicinal flavors cannot be hidden well by blending.

 

Medium roast

Roast dropped just before or just after the onset of second crack. Full city and Viennese are medium roasts.

 

Middle eastern coffee or Turkish coffee

A brewing method in which the roasted coffee is ground very fine, sweetened, boiled, and served without filtering. The grind of the coffee is so fine that most dissolves when brewed while only a few grounds remain at the bottom of a served cup of coffee.

 

Milling

Mechanical removal of the dry parchment skin from wet-processed coffee beans, or the entire dried fruit husk from dry-processed beans.

 

Moldy

Unroasted coffee beans with a light green or white fur-like texture characteristic of mold. Roasted coffee beans affected by mold have a "musty," or "moldy," flavor.

 

Mouthfeel

The in-mouth tactile sensations produced by a beverage. Organic acid A carbon-containing compound with acidic properties.

 

Neapolitan Roast

Term for coffee brought to a degree of roast darker than the typical espresso roast, but not quite black.

 

Open pot

Method of brewing coffee in which grounds are steeped in a pot over heat and the grounds separated or strained prior to serving.

 

Organic Coffee or Certified Organic Coffee

Coffee that has been certified by a third-party company as having been grown and processed without the use of unapproved pesticides, herbicides, or similar chemicals. The third-party company or agency involved in the certification determines what chemicals may or may not be used.

 

Pales

Unroasted yellow coffee beans that stink when crushed or ground. Pales may result from drought or from harvesting immature coffee cherries.

 

Peaberry, Caracol

A small, round bean formed when only one seed, rather than the usual two, develops at the heart of the coffee fruit. Peaberry beans are often separated from normal beans and sold as a distinct grade of a given coffee. Typically, but not always, they produce a brighter, more acidic, but lighter-bodied cup than normal beans from the same crop.

 

Percolation

Technically, any method of coffee brewing in which hot water percolates, or filters down through, a bed of ground coffee. The pumping percolator utilizes the power of boiling water to force water up a tube and over a bed of ground coffee.

 

Pulping

Removing the pulp as part of the wet process. After picking coffee cherries, the first step of processing, using the wet method, is to remove the skin and pulp. Conventional pulping machines have a rotating cylinder that collects harvested cherries immersed in water and presses them against perforations just large enough for the beans to pass. The beans of soft cherries are pushed through the perforations and collected separately while the harder green cherries along with the skin and much of the pulp from the ripe cherries are passed through the machine.

 

Pungent

A strong or sharp taste or smell; usually refers to spiciness.

 

Quakery

A peanut-like flavor that results from processing unripe or underdeveloped coffee beans.

 

Radiant

In coffee roasting, a term describing the transfer of heat from one body to another in close proximity. Reducing sugars In coffee roasting, sugars that donate electrons when reacting with amino acids in Maillard reactions.

 

Respiration

The exchange of gases by coffee beans with their environment.

 

Roast profile

A graphical representation of the progression of bean-probe temperature readings during a roast.

 

Scorching

The burning of bean surfaces during the early stages of a roast.

 

Second crack

A phase during a dark roast in which the release of carbon dioxide from the beans creates loud, popping noises.

 

Shrinkage

The weight lost by coffee beans during roasting.

 

Soluble chemistry

The coffee components that can be dissolved in water.

 

Specialty coffee

Any reference to coffee, or the coffee business, related to the use of higher-quality arabica coffee beans.

 

Taste

The components of flavor perceived by the tongue.

 

Tobacco

The aroma and flavor of fresh tobacco in brewed coffee. A tobacco-like taste is not necessarily disagreeable and is found in various specialty coffees throughout the world. A tobacco-like taste or aroma should not be confused with characteristics of burnt tobacco or ash.

 

Tipping

Burn marks at the long ends, or "tips," of coffee beans.

 

Trowel

A small scoop mounted in the faceplate of a coffee roaster for sampling beans during roasting.

 

Underdeveloped

A term describing a part of a coffee bean's structure not sufficiently broken down by roasting.

 

Vacuum sealing

A packaging method involving the removal of air before sealing.

 

Varietal Coffee

As used by many people in the American specialty coffee industry, a term describing an unblended coffee from a single country, region, and crop. However, to follow the California wine analogy more precisely, varietal coffees ought logically to come from a single predominant botanical variety of coffee tree. Term is often confused with single origin coffees, which are used to describe coffee that comes from a specific country and region in particular, not necessarily region, country, and crop.

 

Viennese roast

A medium-dark roast produced by dropping beans just after the bleeding of oils from bean surfaces.

 

Wet scrubber

A device that passes a roaster’s exhaust air through a spray of water to remove odors and particulates.

 

Whole bean coffee

Coffee that has been roasted but not yet ground.

 

Woody

A taste characteristic of old coffee. Woody coffee has a smell of dry wood, an oak barrel, dead wood, or cardboard. This defect results when beans are improperly stored for an extended period of time. Coffees stored at low altitudes in high temperatures and humidity (as in many ports of shipment) tend to deteriorate quickly and become woody. All coffees can become woody if stored long enough.
