Why is wine acidic?
As you may have noticed before, when sampling a wine, specifically a white wine, you pick up on an acidic or acidic flavour. Have you ever wondered what causes that acidity?
As with most other flavours, this acidity comes from a natural source, specifically the grapes. When they are crushed, we get a juice made up of different types of organic acids, as well as other substances and phenolic compounds.
There are many types of acids in grape juice, but there are the main types, and each of causes a completely different sensation in the mouth. They are:
- Tartaric acid: the hardest and most structured
- Citric acid: the one that gives it is freshness
- Malic acid: more metallic
We should point out that some acidity in wine comes from the fermentation process.
What does acidity do in wine
Acidity is a crucial feature of any wine, for two main reasons.
Firstly and most importantly, acid has a protective function, since it protects wine from certain bacteria that could harm it. As such, only wines with a certain level of acidity can last over time.
But that’s not all! Acidity also has an organoleptic function. Specifically, it’s what makes wines fresh and balanced. As such, its balance with the rest of the flavours is crucial for creating quality wines, such as one of our own delicious Rioja wines.
How to tell if a wine is acidic
There are different ways of knowing or guessing at the acidity of a wine, even before you try it. Here are five basic tips for easily spotting an acidic wine:
- Red wines are always less acidic than white wines or rosés. But that doesn't mean that there’s no acidity in red wine.
- Acidic wines are livelier.
- Think about the type of grapes: some are more acidic than others Sauvignon Blanc or Viura de Rioja.
- The riper the grape in the wine, the greater the concentration of sugars, making the wine less acidic.
- The soil in which the vines grow also affects the acidity. If the wine is from a cold zone, it will probably keep more natural acids than wines from warmer zones.
Tip for finding the acidity in wine
As you know, the taste buds are what help us to perceive each of the flavours. What area of the tongue is stimulated by the acidity in wine? It’s easy: the sides of the tongue, behind where we notice saltiness.
The simplest way to do this is with our own wine. We used El Coto Blanco, a zingy fresh wine with citrus notes, which is just what we need for this test.
Just swill the wine around in your mouth, specifically on the sides of your tongue. Spit the liquid out, lower your jaw and open your mouth. You’ll see where you’re salivating more than normal. This shows that you’re drinking an acidic wine.
