Wine Acidity
Wine is a complex beverage consisting of a variety of compounds that contribute to the taste of the beverage. Acidity is one of the main components of a wine’s taste, along with body, fruit, sweetness and tannin. Acidity plays a key role in making a wine taste good or bad and can determine the wine’s longevity.
To understand how a wine’s acidity affects its taste, one must first understand what acidity is. Acid is a type of chemical compound found in many foods and beverages. It has a sour taste, and it provides a sense of balance and structure to the flavor of a wine.
The primary acids found in wine are tartaric, malic, and citric acid. Tartaric acid is found primarily in white grapes and is responsible for making wines feel tart or tangy on the tongue. Malic acid is found primarily in red grapes and gives wines a green apple flavor when present in large amounts. Citric acid is used primarily in sparkling wines to give them a crisp, lemony flavor.
Different types of wine can have varied levels of acidity. Sparkling wines typically contain higher levels of acidity than their still counterparts. White wines usually contain more acidity than reds. In general, higher acidity wines fare better with food while low acid wines make good sipping wines.
When making wine, winemakers must be aware of the acidity since it can affect how the wine ages. Higher acidity wines are more likely to age properly and last longer. Lower acidity wines, however, will likely not improve with age and can lose flavor quickly. This is why winemakers often adjust the acidity during the fermentation process to achieve the desired flavor profile for the wine.
The acidity of a wine can also affect its overall body, or the way it feels on the palate. Wines with higher acidity tend to have a lighter structure, while low acid wines may have a heavier or thicker body. Wines with higher acidity are also more refreshing and can be good food pairing options.
Overall, acidity is an important characteristic of wine, affecting its taste as well as its ability to age. Winemakers manipulate the acid levels during the fermentation process in order to achieve the desired flavor profile. Knowing the acid profile of different wines can help you decide which wines are best to drink now and which to store for the future.
