The more wines you try, the more you should appreciate a wine’s acidity as an essential element of good taste.
Certainly, it takes a number of things to comprise a well balanced wine. The wine’s fruit flavors, sweetness (or lack of it in drier wines), alcohol level, possible oak aging, and, in the case of red wines, tannins, all factor into the equation.
But acidity may play the most significant role over any of these characteristics, and after you get beyond what I call the “beginners” wine tasting stage – where your taste preferences are usually predominated by sweeter, fruiter wines – you’re much more likely to be aware of wines that display good acidity.
Acidity is essential for a number of reasons. First, it can add a degree of brightness or crispness to a wine. For example, wines that are overly fruity and high in alcohol can sometimes taste fat or flabby. A nice splash of acidity can provide a bit of lift, particularly on the wine’s finish.
Second, acidity can be used as a balancing characteristic, especially in wines with a high residual sugar content. This is because higher acidity helps to offset the wine’s sweetness, and even though the sugar level is the same, your taste buds will perceive it to be less sweet and better balanced.
Third, and what I think is most important, is that wines with good acidity pair naturally well with a number of foods. Acidity helps soften the astringency of high-acid foods like tomatoes and lemons and cuts through the fat content of foods such as salmon, cheeses or heavy cream sauces. This allows you to taste both the food and the wine, which is absolutely paramount in order to maximize your dining experience.
Examples of white wines that are generally high in acidity include riesling, sauvignon blanc, trebbiano and pinot blanc, while notable reds include sangiovese, nebbiolo and pinot noir. Give these wines a try and see if don’t agree that good acidity is a key element in providing the complete package to wine enjoyment.
