Individual flavors may also be detected, due to the complex mix of organic molecules such as esters and terpenes that grape juice and wine can contain. Tasters often can distinguish between flavors characteristic of a specific grape (e.g., Chianti and sour cherry) and flavors that result from other factors in wine making, either intentional or not. The most typical intentional flavor elements in wine are those that are imparted by aging in oak casks; chocolate, vanilla, or coffee almost always come from the oak and not the grape itself.
Banana flavors (isoamyl acetate) are the product of yeast metabolism, as are spoilage aromas such as sweaty, barnyard, band-aid (4-ethylphenol and 4-ethylguaiacol), and rotten egg (hydrogen sulfide). Some varietals can also have a mineral flavor, because some salts are soluble in water (like limestone), and are absorbed by the wine. Wine aroma comes from volatile compounds in the wine that are released into the air.Vaporization of these compounds can be sped up by twirling the wine glass or serving the wine at room temperature. For red wines that are already highly aromatic, like Chinon and Beaujolais, many people prefer them chilled.Etymology
The term was introduced to Europe via the Ottoman Turkish kahve, which is, in turn, derived from the Arabic qahweh. The origin of the Arabic term is derived either from the name of the Kaffa region in western Ethiopia, where coffee was cultivated, or by a truncation of qahwat al-būnn, meaning "wine of the bean" in Arabic. The English word coffee first came to be used in the early to mid-1600s, but early forms of the word date to the last decade of the 1500s. In Ethiopia's neighbor Eritrea, "būnn" (also meaning "wine of the bean" in Tigrinya) is used. Also the Amharic and Afan Oromo name for coffee is bunna.
