Definitions for the vocabulary to describe the flavour of coffee.

Aromas

Animal-like
This odour descriptor is somewhat reminiscent of the smell of animals.  It is not a fragrant aroma like musk but has the characteristic odour of wet fur, sweat, leather, hides or urine.  It is not necessarily considered as a negative attribute but is generally used to describe strong notes.

Ashy
This odour descriptor is similar to that of an ashtray, the odour of smokers' fingers or the smell one gets when cleaning out a fireplace.  It is not used as a negative attribute.  Generally speaking this descriptor is used by the tasters to indicate the degree of roast.

Burnt/Smokey
This odour and flavour descriptor is similar to that found in burnt food.  The odour is associated with smoke produced when burning wood.  This descriptor is frequently used to indicate the degree of roast commonly found by tasters in dark-roasted or oven-roasted coffees.

Chemical/Medicinal
This odour descriptor is reminiscent of chemicals, medicines and the smell of hospitals.  This term is used to describe coffees having aromas such as rio flavour, chemical residues or highly aromatic coffees which produce large amounts of volatiles.

Chocolate-like
This aroma descriptor is reminiscent of the aroma and flavour of cocoa powder and chocolate (including dark chocolate and milk chocolate).  It is an aroma that is sometimes referred to as sweet.

Caramel
This aroma descriptor is reminiscent of the odour and flavour produced when caramelizing sugar without burning it.  Tasters should be cautioned not to use this attribute to describe a burning note.

Cereal/Malty/Toast-like
This descriptor includes aromas characteristic of cereal, malt and toast.  It includes scents such as the aroma and flavour of uncooked or roasted grain (including roasted corn, barley or wheat), malt extract and the aroma and flavour of freshly baked bread and freshly made toast.  This descriptor has a common denominator, a grain-type aroma.  The aromas in this descriptor were grouped together since tasters used these terms interchangeably when evaluating standards of each one.

Earthy
The characteristic odour of fresh earth, wet soil or humus.  Sometimes associated with moulds and reminiscent of raw potato flavour, considered as an undesirable flavour when perceived in coffee.

Floral
This aroma descriptor is similar to the fragrance of flowers.  It is associated with the slight scent of different types of flowers including honeysuckle, jasmine, dandelion and nettles.  It is mainly found when an intense fruity or green aroma is perceived but rarely found having a high intensity by itself.

Fruity/Citrus
This aroma is reminiscent of the odour and taste of fruit.  The natural aroma of berries is highly associated with this attribute.  The perception of high acidity in some coffees is correlated with the citrus characteristic.  Tasters should be cautioned not to use this attribute to describe the aroma of unripe or overripe fruit.

Grassy/Green/Herbal
This aroma descriptor includes three terms which are associated with odours reminiscent of a freshly mowed lawn, fresh green grass or herbs, green foliage, green beans or unripe fruit.

Nutty
This aroma is reminiscent of the odour and flavour of fresh nuts (distinct from rancid nuts) and not of bitter almonds.

Rancid/Rotten
This aroma descriptor includes two terms which are associated with odours reminiscent of deterioration and oxidation of several products.  Rancid as the main indicator of fat oxidation mainly refers to rancid nuts and rotten is used as an indicator of deteriorated vegetables or non-oily products.  Tasters should be cautioned not to apply these descriptors to coffees that have strong notes but no signs of deterioration.

Rubber-like
This odour descriptor is characteristic of the smell of hot tyres, rubber bands and rubber stoppers.  It is not considered a negative attribute but has a characteristic strong note highly recognisable in some coffees.

Spicy
This aroma descriptor is typical of the odour of sweet spices such as cloves, cinnamon and allspice.  Tasters are cautioned not to use this term to describe the aroma of savoury spices such as pepper, oregano and Indian spices.

Tobacco
This aroma descriptor is reminiscent of the odour and taste of tobacco but should not be used for burnt tobacco.

Winey
This terms is used to describe the combined sensation of smell, taste and mouthfeel experiences when drinking wine.  It is generally perceived when a strong acidic or fruity note is found.  Tasters should be cautioned not to apply this term to a sour or fermented flavour.

Woody

Tastes

Acidity
A basic taste characterised by the solution of an organic acid.  A desirable sharp and pleasing taste particularly strong with certain origins as opposed to an over-fermented sour taste.

Bitterness

Saltiness

Sourness
This basic taste descriptor refers to an excessively sharp, biting and unpleasant flavour (such as vinegar or acetic acid).  It is sometimes associated with the aroma of fermented coffee.  Tasters should be cautious not to confuse this term with acidity which is generally considered a pleasant and desirable taste in coffee.

Body
This attribute descriptor is used to describe the physical properties of the beverage.  A strong but pleasant full mouthfeel characteristic as opposed to being thin.
