Acetic Acid All wines contains this main component in vinegar. High levels of acetic acid will dominate the wine and will taste vinegary. The acetic acid develops when a wine is overexposed to oxygen123. |
Acidity All grapes naturally contain acids which are an essential component in wine. Acidity levels should have proper balance with fruit and other components. Sufficient acidity gives liveliness, structure, lingering aftertaste, crispness and is critical for wines to properly mature. High levels of acidity will make the wines taste sour, sharp or tart. Low level will make the wine dull, flat and lacking backbone. |
Aeration The process which allows the wine to absorb oxygen. Decanting the wine or swirling it in a glass will allow the wine to breathe, therefore helping it to open up and develop. The oxygen will allow the wine to release its aromas and give off scents developed in the bottle. |
Aftertaste The flavor sensation the wine provides after swallowing or spitting. Frequently referred to as the 'finish' of a wine. Good wines will have complex and deep aftertaste. |
Age Worthy Contrary to a widely spread belief, only a small number of top wines that have adequate flavor, acidity, alcohol and tannin will achieve additional complexity with time in the bottle. The vast majority of wines are meant to be enjoyed within several years of their release time. |
Alcohol Alcohol is produced during fermentation. Alcohol adds body and a perception of sweetness to wine. |

Aroma Aromas are smells, which originate with the grapes. |
Astringent Wines that leave a coarse, furry or drying sensation in the mouth. Astringency is regularly attributed to high levels of tannin or acid. |
