A

Abyssinica: As well as being the name of our company, it is also a botanical term used to describe all sorts of flora which originate in Ethiopia. Coffea Arabica is the botanical name used to describe Arabica coffee because early botanists first encountered the plant in Yemen. Coffea Arabica Abyssinica is the botanical term used for the unique strains of Coffea Arabica found only in Ethiopia today.

Acerbic: A taste fault in the coffee brew giving an acrid and sour sensation on the tongue. The result of excessive heat after brewing which stews the coffee.

Acid: A characteristic of Arabica coffees, particularly varieties grown at high altitude. Some strains are sought for this particular quality and are called acidy coffees. An acidy coffee has a sharp pleasing taste as opposed to the sweet mellow flavour of non-acidy coffees. There is desirable acidity which is piquant and undesirable acidity which has a sour taste.

Acidity: A term used to describe and grade coffee. It is a primary coffee sensation, created as the acids of a coffee combine with the natural sugars, to increase the overall sweetness of the coffee. It is a pleasant quality that indicates a coffee's flavour and provides a sharpness, or bite to the drink. It is tasted mainly on the tip of the tongue but leaves a dryness at the back of the palate or under the edges of the tongue. Coffees with high acidity are analogous to a dry wine; indeed, several Ethiopian coffees have a distinctly winy aftertaste. The acidity of a coffee may be described as lively, moderate, flat or dull. It is a characteristic of coffees grown at high altitudes such as Yirgacheffe, Sidamo, and Harar. It is NOT, however, the same as bitter or sour. Coffees are low in acidity, between 5 and 6 on the pH scale.

Acrid: A secondary coffee taste sensation characterized by a sour sensation on the back sides of the tongue. Caused by higher-than-normal percentage of sour acids and a high concentration of salts. This is relatively common in unwashed coffee from the Americas but is very rare in Ethiopian coffees.

Aftertaste: The sensation of brewed coffee vapours, released from the residue remaining in the mouth after swallowing. It can range from chocolaty to spicy. 

Alkaline: A coffee taste sensation caused by the presence of alkaloid compounds. It is characterized by a dry sensation at the back of the tongue.

Aged: A taste taint that gives coffee beans a less acidy taste and greater body. The result of enzyme activity in the green coffee beans creating a chemical change during the aging process after harvesting.

Americano: A milder drink suitable for drinking several large mugs. It consists of a shot, or sometimes two, of espresso poured into a mug of hot water.

Arabica: A specific variety of coffee (Coffea Arabica). Considered to be the best variety of coffee because of its fruity, acidic taste and low caffeine content. Arabica is the most expensive variety of coffee and accounts for nearly all of the specialty coffee market. "Coffea Arabica" is the species name assigned to the coffee tree by European botanist Linnaeus while categorizing the flora of the Arabian peninsula.

Aroma: The fragrance of brewed coffee which is the best way to experience the subtle floral notes of some coffees. 

Aromatic: A term used to describe and grade coffee. It designates a coffee that fully manifests the aroma characteristic of its nature and origin.

Astringent: A secondary coffee taste sensation characterized by a predominantly searing, salty sensation on the upper sides of the tongue. Caused by acids increasing the saltiness.

B

Bag: A sack of coffee which is usually 60kg but in some countries is 50kg or 70kg.

Baggy: An unpleasant taste caused by weakly roasted coffees that have been stored for a long time in unsuitable conditions.

Baked: A taste and odour that gives the coffee a flat aroma and bland taste. It is the result of the roasting process taking too long because insufficient heat is created. Roasting terminology ranks this unpleasant characteristic in three levels of intensity: cooked, baked or burnt.

Balanced: A term used to describe and grade coffee. It indicates a coffee in which a particular characteristic does not overwhelm all the others; thus, there is enough complexity to interest drinkers.

Barista: The name given to a person whose full-time job is brewing coffee.

Basic Tastes: The four primary taste sensations which our tongues can detect: sweet, sour, salt, and bitter. Characterized respectively by sucrose, tartaric acid, sodium chloride, and quinine.

Batch Roaster: A machine which roasts a given quantity at one time. It does not continually roast beans. It comes in many different capacities  but small independent roasters usually have a machine with a capacity between 15kg and 60kg.

Beany: The aroma of an insufficiently roasted coffee that has not been able to develop its full aroma.

Biscotti: A hard biscuit that has been baked twice and is often served with coffee.  Good for dunking.

Bitter: A term used to describe and grade coffee. It is a characteristic of an over-extracted brew (too little coffee at too fine a grind) as well as over-roasted coffees, and those with various taste defects; it is a harsh, unpleasant taste detected towards the back of the tongue. This is a desirable characteristic at a certain level and is why dark roasts have some popularity. Robusta coffee is distinctly more bitter than Arabica.

Black Beans: Over-ripe coffee cherries that have been harvested too late or have dropped from the trees. They should be discarded because they have a detrimental effect on taste.

Bland: The absence of flavour often found in low grown Robusta coffees. Also caused by under extraction (too little coffee or too coarse a grind).

Blend: A mixture of two or more individual varieties of coffee.

Bodum: This is a trade name of a specific brand of French press/plunger pot. However, the name has become somewhat synonymous with the term French press pot. Also commonly called a Cafetiere.

Body: A term used to describe and grade coffee. It describes the impression of the density and consistency of the coffee in the mouth. It may range from thin to medium or from full to buttery and syrupy. Heavy-bodied coffee is the best drunk with milk and light-bodied coffee is best drunk black.

Bouquet: A term used to describe and grade coffee. It is used to describe the total aromatic profile of a coffee resulting from the volatile organic compounds present in the fragrance, aroma, nose and aftertaste. It is also used as a term to describe the fragrance of freshly ground coffee.

Brackish: A taste fault giving the coffee brew a salty and alkaline sensation. The result of salts and inorganic alkaline material left after evaporation of water from the brew due to excessive heat after brewing.

Brazil: The largest coffee growing country in the world.

Bready: A term used to describe coffees that have not been roasted long enough or at a high enough temperature to bring out the essential oils.

Brève: Cappuccino made with light cream.

Bright: Tangy acidity is often described as bright.

Briny: The salty sensation caused by excessive heat after brewing or over-roasting.

Buttery: A rich and oily flavour caused by oily material suspended in the coffee beverage. The result of substantial amounts of fat present in the beans. Most often a characteristic of high coffee-to-water ratio brews.

Chocolaty: A term used to describe and grade coffee. It is an aromatic aftertaste of unsweetened chocolate or vanilla.

City or Full City Roast: Stages in the roasting process when most of the aromatic oils are produced. Beans can be oily and shiny if the roasting process is stopped at this time.

Complexity: A term often used to describe blended coffees but not restricted to them. If a coffee has good complexity it should have a harmonious multiplicity of taste sensations.

Cooked: A term used for coffee that has been brewed at too hot a temperature for too long.

Crema: The tan foam that forms when you brew espresso. The crema makes a 'cap' which helps to retain the flavours and aromas of the espresso within the cup. Crema is due to colloids and lipids forced out into an emulsion under the pressure of an espresso machine.

Cupping: A term used by coffee professionals to describe the activity of sipping brewed coffees to assess their qualities.
